Diabetes and Omega-3’s

Diabetes, Omega-3 fatty acids Super FoodsReading, interpreting and understanding scientific literature can be tedious because the authors often find that their previous paper on the subject missed its mark or was completely wrong. Easy to do when you are blazing new trails; however, the caution they go through to cover their tracks oftentimes makes for difficult reading. Luc Djousse and his colleagues at the U of Washington reported in the May 18, 2011 edition of the American Journal of Clinical Nutrition that, “With the use of objective biomarkers, long-chain omega 3 Fatty Acids (FAs) and Alpha-Linolenic Acid (ALA) were not associated with a higher incidence of diabetes. Individuals with the highest concentrations of both types of FAs had lower risk of diabetes.”

Speed reading is absolutely out of place. Omega-3 fatty acids in the body help to control the inflammation process, which is a benefit because the start of the healing process—initiated by the omega-6 arachidonic acid—also involves the possibility of getting carried away with the exercise. Say you have a cut or abrasion. The key activity that ensues is to stop the loss of fluids – save the blood.  It is that process which tells the body to start the healing by sending white blood cells and platelets to the site of the wound and to agglomerate and close the exit door by swelling the tissues, which is also another way of looking at inflammation. To inflame can be life saving. The omega-3’s are then involved in the work of modulating the activity helping to ease the inflammation that comes with the correction process.

Fatty acids, especially those that are long and highly unsaturated, increase cell membrane fluidity and functionality. Fatty acids are essential to membrane activity at the location of hormone receptors. Insulin resistance in adult-onset diabetes is directly associated with fewer membrane enhancing long-chain fatty acids, largely due to impaired function of desaturase and elongase enzymes needed for a healthy membrane. Ruiz-Gutierrez 1993, “We have studied the fatty acid composition of erythrocyte membrane phospholipids in nine Type 1 (insulin-dependent) diabetic patients and nine healthy control subjects. Cell membranes from the diabetic patients showed a marked decrease in the total amount of polyunsaturated fatty acids mainly at the expense of docosahexaenoic acid, DHA, and arachidonic acid C20:4n6”.

Cell membrane abnormalities in lipid content are found to be related to poor metabolic control, which is a characteristic of diabetes. Diet is a very important  factor, and interventions with dietary essential fatty acids (EFAs) in the correct ratio (found to be 4:1, omega-6:omega-3), can make a difference. Decsif  T., 2002, “Reduced availability of long-chain polyunsaturates in diabetic children suggests that an enhanced dietary supply of long-chain polyunsaturates may be beneficial”. Children with diabetes demonstrate a deficit of long-chain fatty acids, so incorporating them into a child’s diet is prudent. An unspoken benefit in the application of EFA’s to diabetes treatment is the decrease in triglyceride levels, themselves striking indicators of the potential for cardiovascular issues and very often appearing in persons with diabetes.

Herein resides the prolonged physiological support of the EFAs. For those who lack the efficient conversion of the omega-3 alpha linolenic acid from plant sources (notably flaxseeds and their oil) to EPA and DHA, fish oil may be a viable alternative. In fact the the FA conversion process with diabetes is almost non-existent, but also common with aging.

For quite some time the essential fatty acids have been misunderstood. Of the types of fatty acids, the omega-3’s have received the most publicity, having been applauded for positive health effects, principally, because over the last century the general population ate little fish and had little or no n-3s in the diet. Unless they were more or less health nuts, few did not have any exposure to omega 3s as in flax, and even if they did their ability to elevate up to EPA and DHA was minimal. Fish oil was the answer but the explosion that ensued caused over-consumption and still does.

Hence the comments of Djousse et al that n-3 FAs did not increase diabetes but if both the omega 6s and the 3 s were added together there was marked improvements. There is an inference that n-3s were of no benefit and needed the balance of both EFAs, which we applaud and so should you. Balance is paramount.

Soda and Obesity

type 2 diabetes, obesityWhile a major study relating soda and obesity was done in California, the hypothesis, observations and outcomes are applicable to all the states of the Union.  More than half the adolescents in that state and almost a fourth of the adults treat themselves to at least one sweetened beverage every day.  One of the concerns expressed by UCLA researchers is that the serving size has grown from an average of 6.5 ounces and eighty-eight calories in the 1950’s to 20 ounces and two hundred sixty-six calories by the 2000’s.  In fast food restaurants in 2003, the average serving was 23 ounces (almost 300 calories).  These added caloric sweeteners, including high fructose corn syrup, are not only markers of a poor diet, but also are associated with overweight and obesity in all age groups.

CITATIONS FROM REPORT / ARTICLE
The UCLA Health Policy Research Brief from September, 2009, reports from its data that, “Adults who drink soda occasionally (not every day) are 15% more likely to be overweight or obese, and adults who drink one or more sodas per day are 27% more likely to be overweight or obese than adults who do not drink soda, even when adjusting for poverty status and race/ethnicity.”  Even though the prevalence of overweight in children is lower than in adults, the rates among children have increased more.  In fact, overweight has tripled in teenagers and quadrupled in those from six to eleven years old in the last three decades.  In California the cost of obesity approaches twenty-one billion dollars a year, burdening families, employers and the health care industry.  The study comments that, “California spends more public and private money on the health consequences of obesity than any other state.”  To compound the matter, the article admits that “…drinking soda is also associated with increased risk for type 2 diabetes.”

COMMENTARY
One third of American adults are obese. Their health care costs $1500 more a year than it does for an average-weight person.  The Center for Disease Control announced in July, 2011, that obesity in the entire United States costs $147 billion a year in direct medical costs.  Dr. Thomas R. Frieden, director of the CDC, said the problem is “getting worse rapidly.  The average American is now 23 pounds overweight.”  For Medicare, the cost of obesity is 72% greater just for prescription drugs.  The CDC says that one in three children born in 2000 will develop diabetes.  How did we get there?  Diet.  Does the rest of the world share the problem?  Yes.  Where does the blame go?  White flour, white sugar, high fructose corn syrup, soft drinks and fast food.

Whether it gets marketed as corn sugar or as high fructose corn syrup, which is what it is, this commodity is not equal to other sweeteners when it comes to weight gain.  HFCS costs less than table sugar because, being liquid, it’s easier to transport and blend.  It’s sweeter than sucrose (table sugar), so less is needed, and it’s cheaper because of a combination of corn subsidies and sugar tariffs and quotas.  Cheap corn, in fact, is the building block of the fast-food nation.  Cheap corn created the chubby 20-ounce bottle of soda we have today.

High fructose corn syrup commonly is 55% fructose and 45% glucose, somewhat different from the 50-50 mix in table sugar, where one fructose molecule is attached to one glucose molecule.  Some HFCS may be as high as 80% fructose.  Since all sugars contain four calories per gram, there must be something else about fructose that matters.  Fructose is metabolized more rapidly that glucose, flooding metabolic pathways and increasing triglyceride storage.   It doesn’t spur the production of insulin or leptin, the hormone that sequesters appetite.  The body then lacks satiety.  This elevates serum triglycerides and increases fat storage.  Since it may have less impact on appetite than glucose, fructose contributes to weight gain.  Ingesting lots of fructose may also reduce insulin sensitivity.  (Beck-Nielsen, 1980)

Soft drink consumption has more than doubled in the twenty years from 1977 to 1997.  Not surprisingly, obesity followed the same trend. Cause and effect? It’s been estimated that for each additional sweet drink consumed per day, the odds of obesity increase by sixty percent.  A study of more than fifty thousand nurses by Harvard compared time periods from 1991-1995 and 1995-1999, and found that women whose soda consumption increased had bigger rises in body-mass index than those who drank less or the same amounts of soda. Fast food seems to go well with it.  Unhealthy foods get along nicely with each other.

The debate between the soft drink industry and the health nuts is ongoing.  People who consume lots of fresh-squeezed juices, vegetables and fruits are not the same group that consumes soda and cold cut sandwiches.  The daily calories from soft drinks account for almost a fourth of the recommended daily intake for many Americans, who drink almost fifty-six gallons of soda a year.

In case you’re interested, more than 30% of Americans are obese. More than 24% of Mexicans, 23% of British, 22% of Slovakians, 22% of Greeks and Australians, 21% of New Zealanders, and 15% of Czechs, but only 3% of Japanese and Koreans. Go figure. Obesity, by the way, means being more than 20% above ideal weight for height.

Bubbling Over: Soda Consumption and Its Link to Obesity in California
Susan H. Babey, Malia Jones, Hongjian Yu and Harold Goldstein

In California, 62% of adolescents ages 12-17 and 41% of children ages 2-11 drink at least
one soda or other sweetened beverage every day. In addition, 24% of adults drink at least
one soda or other sweetened beverage on an average day. Adults who drink soda occasionally
(not every day) are 15% more likely to be overweight or obese, and adults who drink one or
more sodas per day are 27% more likely to be overweight or obese than adults who do not
drink soda, even when adjusting for poverty status and race/ethnicity.

The prevalence of overweight and obesity has increased dramatically in both adults
and children in the last three decades in the United States. In the 1970s, about 15% of
adults were obese and by 2004 the rate had climbed to 32%.1 Although the prevalence of
overweight among children is lower than among adults, the rates among children and
adolescents have increased considerably more. The prevalence of overweight and obesity
nearly tripled among 12-19 year olds and more than quadrupled among 6-11 year olds
in the last three decades.

In California, 21% of adults are currently obese and an additional 35% are overweight. Among adolescents, 14% are obese and another 16% are overweight.2 Similar to national trends, the trend in California is toward increasing weight in both adults and adolescents.3 Each year in California, overweight and obesity cost families, employers, the health care industry and the government $21 billion.4 California spends more public and private money on the health consequences of obesity than any other state.5

Overweight and obesity are associated with serious health risks. In children and adolescents, overweight and obesity are associated with increased risk for cardiovascular disease indicators including high total cholesterol, high blood pressure, and high fasting insulin, an early indicator of diabetes risk.6 In addition, overweight children and adolescents are more likely to be overweight or obese as adults.7 In adults, overweight and obesity are associated with increased risk for diabetes, heart disease, stroke, some types of cancer and premature death.1, 8, 9

Drinking sweetened beverages such as soda and fruit drinks that have added caloric sweeteners (e.g., sucrose, high fructose corn syrup) is one marker of a poor diet, and is
associated with overweight and obesity in people of all ages.10-13 A number of studies have found that greater consumption of sweetened beverages is associated with overweight and obesity among both adults and children.12-19 In addition, randomized controlled trials that examine the impact of reducing intake of sweetened beverages on weight indicate
that reducing consumption of soda and other sweetened drinks leads to reductions in
overweight and obesity.20, 21 Among adults, drinking soda is also associated with increased risk for type 2 diabetes.13 Moreover, drinking sweetened beverages has
increased, and it is now more common than ever, particularly among adolescents.22
Between 1977 and 2002 Americans increased their calorie intake from soft drinks by
228%.23 Portion sizes have also increased from an average serving size of 6.5 fl oz (88 calories) in the 1950s, to 12 fl oz (150 calories), 20 fl oz (266 calories), and even larger portion sizes common today.24-26 The average serving size of soft drinks in fast food restaurants in 2002 was 23 fl oz (299 calories), with some chains now commonly selling soft drinks in 32 to 64 fl oz portions (416 to 832 calories, respectively).27 Sweetened beverages are a significant contributor to total caloric intake, especially for children and adolescents, and they lack the nutrients our bodies need.24, 26, 28

Additionally, eating habits established in childhood are important determinants of
eating habits as adults.29, 30

Impaired cellular insulin binding and insulin sensitivity induced by high-fructose feeding in normal subjects
H Beck-Nielsen, O Pedersen and HO Lindskov

We have studied whether the sucrose-induced reduction of insulin sensitivity and cellular insulin binding in normal man is related to the fructose or the glucose moiety. Seven young healthy subjects were fed their usual diets plus 1000 kcal extra glucose per day and eight young healthy subjects were fed their usual diets with addition of 1000 kcal extra fructose per day. The dietary regimens continued for 1 week. Before change of diet there were no statistically significant differences between body weight and fasting plasma concentrations of glucose, insulin, and ketone bodies in the two groups studied. High- glucose feeding caused no significant changes in insulin binding or insulin sensitivity whereas high-fructose feeding was accompanied by a significant reduction both of insulin binding (P less than 0.05) and insulin sensitivity (P less than 0.05). The changes in insulin binding and insulin sensitivity correlated linearly (r = 0.52, P less than 0.01). We conclude that fructose seems to be responsible for the impaired insulin binding and insulin sensitivity induced by sucrose.

Soft drinks and weight gain: how strong is the link?
Wolff E, Dansinger ML.
Boston University School of Medicine, Boston, Massachusetts, USA. [email protected]

CONTEXT
Soft drink consumption in the United States has tripled in recent decades, paralleling the dramatic increases in obesity prevalence. The purpose of this clinical review is to evaluate the extent to which current scientific evidence supports a causal link between sugar-sweetened soft drink consumption and weight gain.

EVIDENCE ACQUISITION
MEDLINE search of articles published in all languages between 1966 and December 2006 containing key words or medical subheadings, such as “soft drinks” and “weight.” Additional articles were obtained by reviewing references of retrieved articles, including a recent systematic review. All reports with cross-sectional, prospective cohort, or clinical trial data in humans were considered.

EVIDENCE SYNTHESIS
Six of 15 cross-sectional and 6 of 10 prospective cohort studies identified statistically significant associations between soft drink consumption and increased body weight. There were 5 clinical trials; the two that involved adolescents indicated that efforts to reduce sugar-sweetened soft drinks slowed weight gain. In adults, 3 small experimental studies suggested that consumption of sugar-sweetened soft drinks caused weight gain; however, no trial in adults was longer than 10 weeks or included more than 41 participants. No trial reported the effects on lipids.

CONCLUSIONS
Although observational studies support the hypothesis that sugar-sweetened soft drinks cause weight gain, a paucity of hypothesis-confirming clinical trial data has left the issue open to debate. Given the magnitude of the public health concern, larger and longer intervention trials should be considered to clarify the specific effects of sugar-sweetened soft drinks on body weight and other cardiovascular risk factors.  PMID: 18924641

Sugar-sweetened beverages and risk of metabolic syndrome and type 2 diabetes: a meta-analysis.
Malik VS, Popkin BM, Bray GA, Després JP, Willett WC, Hu FB.

Department of Nutrition, Harvard School of Public Health, and Department of Medicine, Brigham and Women’s Hospital, Boston, MA, USA.

OBJECTIVE
Consumption of sugar-sweetened beverages (SSBs), which include soft drinks, fruit drinks, iced tea, and energy and vitamin water drinks has risen across the globe. Regular consumption of SSBs has been associated with weight gain and risk of overweight and obesity, but the role of SSBs in the development of related chronic metabolic diseases, such as metabolic syndrome and type 2 diabetes, has not been quantitatively reviewed.

RESEARCH DESIGN AND METHODS
We searched the MEDLINE database up to May 2010 for prospective cohort studies of SSB intake and risk of metabolic syndrome and type 2 diabetes. We identified 11 studies (three for metabolic syndrome and eight for type 2 diabetes) for inclusion in a random-effects meta-analysis comparing SSB intake in the highest to lowest quantiles in relation to risk of metabolic syndrome and type 2 diabetes.

RESULTS
Based on data from these studies, including 310,819 participants and 15,043 cases of type 2 diabetes, individuals in the highest quantile of SSB intake (most often 1-2 servings/day) had a 26% greater risk of developing type 2 diabetes than those in the lowest quantile (none or <1 serving/month) (relative risk [RR] 1.26 [95% CI 1.12-1.41]). Among studies evaluating metabolic syndrome, including 19,431 participants and 5,803 cases, the pooled RR was 1.20 [1.02-1.42].

CONCLUSIONS
In addition to weight gain, higher consumption of SSBs is associated with development of metabolic syndrome and type 2 diabetes. These data provide empirical evidence that intake of SSBs should be limited to reduce obesity-related risk of chronic metabolic diseases.

The obesity epidemic in the United States.
Morrill AC, Chinn CD.
Capacities Inc., Watertown, Massachusetts 02471, USA. [email protected]

We describe the epidemic of obesity in the United States: escalating rates of obesity in both adults and children, and why these qualify as an epidemic; disparities in overweight and obesity by race/ethnicity and sex, and the staggering health and economic consequences of obesity. Physical activity contributes to the epidemic as explained by new patterns of physical activity in adults and children. Changing patterns of food consumption, such as rising carbohydrate intake–particularly in the form of soda and other foods containing high fructose corn syrup–also contribute to obesity. We present as a central concept, the food environment–the contexts within which food choices are made–and its contribution to food consumption: the abundance and ubiquity of certain types of foods over others; limited food choices available in certain settings, such as schools; the market economy of the United States that exposes individuals to many marketing/advertising strategies. Advertising tailored to children plays an important role.  PMID: 15683071

Diet Soda is Not A Free Ride

diet soda & weight gainThere is little doubt that obesity in America is on the upswing. Lots of people think that an artificially-sweetened beverage can offset the poor dietary decisions to which they have become accustomed. There has been established a relationship between non-sugar sweeteners and weight gain based on physiological responses to the message of satiety and the perceived need to consume more calories to achieve it. While the perception of sweet taste is supposed to satisfy appetite, the calculated deception to the body just might boomerang and call off all bets.

In the San Antonio Heart Study that ran from 1979 to 1988, researchers examined the association of artificially sweetened beverages with long-term weight gain, and found that, “A significant positive dose-response relationship emerged between baseline ASB (artificially sweetened beverage) consumption and all outcome measures…”  These outcome measures included overweight / obesity, weight gain, and changes in body mass index (BMI).  As with most nutrition research, considerations were made for demographics and behavioral characteristics.  Drinking more than twenty-one ASB’s a week had the most impact, with “…almost double risk of overweight / obesity among 1,250 baseline normal-weight individuals.”  For those with a body mass index already elevated, the changes were more pronounced.  This report concluded with, “These findings raise the question whether AS (artificial sweetener) use might be fueling—rather than fighting—our escalating obesity epidemic.”

That last sentence from the San Antonio Heart Study is quite the incrimination, would you say?
Diet soft drinks have long been thought to be healthier alternatives to their sugary counterparts, but reports like this one have linked increased incidence of weight gain, metabolic syndrome, and even diabetes to frequent intake of diet soft drinks.  Keep in mind, though, that all studies in all areas of health care are subject to scrutiny and critique.    Regardless of the topic, there are always two—or more—sides.  But here it may have been discovered that fooling the body is the instigator behind the concern.

When the body is told that something sweet has been ingested, it launches the production of insulin to carry the sweet to the cells to be burned for energy.  By the time the body finds out that there really is no sugar to be burned—in the form of glucose—the insulin has already been sent on its way to work.  Now the insulin has to find something to do, so it initiates a signal that says, “Feed me.  I need to carry glucose.”  That arouses hunger.  What do we grab for immediate satisfaction?  Carbohydrates, the simpler, the better.  Most of them spike glucose rapidly, which, if it fails to get burned for energy, is stored as fat.  It now appears that a lack of exercise becomes part of the equation.

There’s another tack to look at.  Some artificial sweeteners are alleged to block the brain’s production of serotonin, the neurotransmitter that controls mood, learning, sleep, and…appetite.  When the body experiences low levels of serotonin—and that can affect depressed mood—it seeks foods that can bring the levels back up.   Those foods happen to be the ones that will also bring the belt size up. Real sugar, of course, provides empty calories that can also cause weight gain as excessive energy intake.  But a weight conscious public does what it thinks is right.

Sweet taste enhances appetite.  Aspartame-sweetened water, for example, increased subjective hunger ratings when compared to glucose-sweetened water.  (Yang. 2010)  Other artificial sweeteners were associated with heightened motivation to eat, with more items selected on a food preference list. (Blundell. 1986)  This suggests that the calories in natural sweeteners trigger a response to keep overall energy intake constant, and that inconsistent coupling between sweet taste and actual caloric content can lead to compensatory overeating and consequential positive energy balance.  (This means that more energy came into the body than went out.)  People associate taste with calorie content.  You can tell that a crème brulee has more calories than the eggs from which it is made, but you’d probably eat more of it if made with artificial sweetener than with cane sugar.

Humans have a hedonic component.  We like those things that appeal to the senses and activate our food reward pathways.  That contributes to appetite increase.  But artificial sweeteners fail to provide completeness.  Unsweetening the American diet over the long haul, a little at a time, might just do the trick.  After all, it seems to work with salt.

Maple Syrup – M’m! M’m! GOOD!

anti-diabetes maple-syrupAstounding as it may seem, maple syrup—real maple syrup—has been found to have anti-cancer and anti-diabetes properties. Plant researchers at the University of Rhode Island have isolated compounds from maple tree sap that are strikingly beneficial to human health. What’s more, some of these compounds are brand new, and surface only after the sap is processed into syrup.

A Science Daily report from March, 2011, announces that the University of Rhode Island medicinal plant researcher, Navindra Seeram, has discovered thirty-four new beneficial compounds in pure maple syrup to be added to the twenty he found the year before, “…five of which have never been seen in nature.” The researcher is quoted, “It’s important to note that in our laboratory research we found that several of these compounds possess anti-oxidant and anti-inflammatory properties, which have been shown to fight cancer, diabetes and bacterial illnesses.” Seeram applauds Mother Nature as the best chemist, commenting that, “…maple syrup is becoming a champion food when it comes to the number and variety of beneficial compounds found in it.” (Science Daily; Mar. 30, 2011) Seeram’s team acknowledges that inflammation is at the center of several nefarious disease, including heart disease, diabetes, certain cancers, and neurodegenerative diseases such as Alzheimer’s. The maple syrup compounds may show medicinal promise, but the scientists suggest that consumers not consume large quantities of the syrup, but to use it instead of artificial products found in the marketplace.

The scientific names of the compounds derived from maple syrup are enough to scare you away.  With thirty or more letters and numbers, these unpronounceable words sound serious.  And they are.  Among them are phenolic compounds and plant lignans, the former having anti-oxidant properties and the latter having hormonal properties.  Of these two major constituents, the phenolics are more active (Li and Seeram. 2010), and were found to be comparable to vitamin C (Li and Seeram. 2011).

Plants make certain chemicals for themselves, often to remain protected from predation or environmental damage, as may occur from heavy metal exposure via exhaust from the electric company’s smokestack, which often contains mercury.  These beneficial chemicals transfer to us when we eat those plants, where they may act as chelators besides anti-oxidants.  The more a plant is stressed, the more it produces phenolic anti-oxidants, the bioflavonoids being the best-known among them.

Real maple syrup demonstrates quite a nutritional profile compared to the fake stuff, which is primarily high-fructose corn syrup (HFCS) flavored with a synthetic ingredient.  Ounce for ounce, maple syrup has slightly fewer calories and carbohydrates than HFCS, eleven times the calcium, and more magnesium and zinc.  Plus, it tastes a whole lot better.

Two phenols in maple syrup, ethyl acetate and butanol, are able to inhibit enzymes that are relevant to Type 2 diabetes (Apostolidis. 2011), with butanol being more active.  Additionally, butanol converts to butyric acid, which plays a role in DNA transcription.  Real maple syrup is allowed to be labeled as such.  In Quebec, the largest producer of real maple syrup, the locals refer to imitation syrup as “pole syrup,” implying that it has been tapped from telephone poles.  That’s not too outlandish a comment.   In fact, a brand new compound that forms only during the processing of the sap has been named quebecol, in honor of the Province.  (Li and Seeram. J Func Food. 2011)  It is not uncommon for heat (in this case, sap boiling) to separate chemical components and then rearrange them to form something else, all mass being retained.

It had already been established that anti-oxidants reside in the leaves, bark and twigs of the maple tree, so examining the sap is a logical step.  Exposure to direct sunlight appears to enhance anti-oxidant production.  Besides Seeram, other research teams, especially from Canada, have hopped onto the maple syrup train.  Because all these scientists are headed in the same direction, why not?

Diabetes Prevention: Can We Stop Type 2 Before It Starts?

weigh-inPredictions for an increase in diabetes are dreadful. One in three children born in the United States in the year 2000 are apt to become diabetic unless they change the way they eat and start to move more. The implications of this epidemic are frightening because blindness, amputations, kidney failure and heart disease are in their futures. From the mid 60’s to the mid 90’s, the number of diagnosed diabetes cases has tripled. The type 2 diabetes that appeared at age forty is now showing up at age twelve. Almost all of those kids are overweight.

The Department of Health and Exercise Science at Wake Forest University, in North Carolina, recently concluded a study of the Diabetes Prevention Program that focused on lifestyle influence on type 2 diabetes, and found that overweight and lack of exercise are still principal causes of the disease.  The study included more than three hundred volunteers with body mass indexes (BMI) between 25 and 40, some of whom served as controls, while the others received a diabetes education program that included dietary interventions.  By now, you already figured that the intervention group experienced significantly greater decrease in glucose, insulin, and insulin resistance.  Not only that, but also they lowered their BMI’s and lost about an inch from their waistlines.  (Katula. 2011)  Getting rid of that gut makes a ton of difference.  (Pun intended.)  Parallel studies at Indiana University Medical School yielded similar results, with the additional benefits of improved blood pressure and total cholesterol levels.  (Ackerman. 2011)

In type 1 diabetes, where insulin is required, science is trying to prevent the loss of beta cells, the ones in the pancreas that make insulin.  Examining genetic susceptibility to disease is one step in the process.  Family history is part of that.  Up to now, there are no known pre-diagnosis steps that can be taken to prevent the onset of type 1.  On the other hand, there are several possibilities for helping to save beta cells shortly after a diagnosis of diabetes.  (Wherrett. 2011)  Assiduous effort is put into this area, with the expectation that some factors known to trigger autoimmunity and the eventual destruction of beta cells can be controlled.  Early trials offer promise, but have not yet reached fruition.  (Thrower.  2009)

The list of diabetic complications is long and fearsome:  coronary artery disease, cerebrovascular disease, peripheral vascular disease, retinopathy, and neuropathy, to name a few.  Researchers are looking closely at plants that can offset the costs and side effects of pharmaceuticals, and even obviate their use, but admonish us that diet and lifestyle still need to be reined in.  (Haque. 2011)  Because soy foods are integral to Asian cuisine, it seems appropriate to look for components of soy chemistry that might affect blood glucose.  The soy phytoestrogen, genistein, was reported to protect against glucose-induce pancreas cell death in a study done in China.  (Zhong. 2011)  The applicability of this finding to either type 2 or type 1 diabetes, or both, is yet to be determined, but the prospects have merit.

Patients already diagnosed with type 2, or those who feel themselves candidates, may be comforted to know that alpha lipoic acid, a sulfur compound found in organ meats, spinach and broccoli, and also available as a supplement, prevents a rise in diabetes markers while improving the efficiency of glucose metabolism.  In German studies it was found that administration of alpha lipoic acid for ten days, either orally or intravenously, improves insulin sensitivity in both lean and obese individuals.  (Konrad. 1999)  (Jacob. 1999)  It would be imprudent, though, to expect supplemental alpha lipoic acid to do something we wouldn’t do for ourselves, such as lose weight and exercise.

Dietary fiber gets lots of attention, and is mostly associated with digestive health.  The soluble type is fermented in the gut and makes some physiologically active byproducts.  The insoluble type is comparatively inert and absorbs water to make elimination an efficient process.  Legumes, some cereals and fruits, psyllium, and tuberous vegetables provide soluble fiber.  Wheat and corn bran, whole grains, and nuts and seeds are sources of insoluble fiber.  Psyllium has received considerable interest as an ingredient in high-fiber breakfast cereals, where it’s been reputed to lower cholesterol and to reduce blood glucose response to a meal.  More than one study has reported psyllium to be effective for both.  As little as 5 grams of psyllium taken either with, or just before, a meal has effected improvement in lipid and glycemic control.  At the University of Virginia Diabetes Center, scientists noted a 14% reduction in postprandial glucose at breakfast, and a 20% reduction at dinner, compared to placebo, in people diagnosed with non-insulin-dependent type 2 diabetes.  (Pastors. 1991)  Analyses in Mexico and Texas arrived at the same conclusion, but recorded a pronounced positive effect on total cholesterol, LDL cholesterol and triglyceride levels.  (Rodriguez-Moran. 1998)  (Lee. 1994)

The United States is not alone in the quest to control the diabetes epidemic by recommending lifestyle changes.  The Japanese saw a risk reduction of more than 67% through weight loss, and the Finns realized risk reduction by controlling total and saturated fats and increasing dietary fiber, as well.  (Kosaka. 2005)  (Lindstron.  2006).   Globally, children do not eat enough vegetables.  Those who do, often limit their repertoire to only a few.  French fries don’t count.   What they are missing is magnesium, the prophylactic mineral that is able to improve glucose and insulin balance, especially in obesity.  (Song. 2004)  (Huerta. 2005)  (Lopez-Ridaura. 2004) This mineral is loaded with properties that boost health. The prevention of diabetes is as simple as exercising, losing a few pounds, getting ample fiber, and eating magnesium-rich produce.  Here, an ounce of prevention really is worth a few pounds of cure, not to mention getting stuck with a needle.

Beta-Glucans, The Healer

oatmeal-and-white-backgroundThere are quite a few products on the market that promise to heal wounds quickly. The one made from a combination of bacitracin, neomycin and polymyxin is so popular that it’s been copied as a generic. But it isn’t all-natural. For those interested in a natural alternative, there’s a new kid on the block, called beta-glucans, found in baker’s yeast and a few other common sources, and destined to be on the shelves as a gel in 2012. Heralded as a “super medicine,” beta-glucans are currently used in veterinary medicine, dietary supplements, and cosmetics. And Norwegian scientists say it has even more potential.

The Research Council of Norway announced the results of a study headed by Rolf Einar Engstad, of Biotec Pharmacon, that proclaimed, “Since the mid-1980’s we have known that these substances (beta-glucans) fight infection and have a bearing on the body’s ability to kill cancerous cells, but never knew why.”  At the start of the project, the researchers were uncertain of the efficacy of the delivery method, but in infected laboratory animals, “…determined that animals receiving beta-glucans orally acquired protection that was at least as good as rats that received an injection into their bloodstream.”  Effectiveness of topical application in the healing of wounds was welcome news.  Incisions, bed sores, diabetic ulcers, and other skin insults can be treated with topical beta-glucans.  A matter that has since been addressed is short shelf life, something that can happen to any organic material, such as organic produce.  To add to beta-glucans’ acclaim is its capacity to enhance the innate immune system, that immunity with which we are born and which is first mobilized if the body is invaded by a pathogen.  (The Research Council of Norway.  2011)

As a supplement, beta-glucans has been around for a while.  These sugars are found in the cell walls of bacteria, fungi, yeasts, algae, lichens, and plants, such as oats and barley.  Orally, they have been used for treating cholesterol, diabetes, cancer and HIV/AIDS, and for bolstering the immune systems of those suffering from chronic fatigue syndrome and emotional or physical stress.  It may be given IV post-surgery to prevent infections.  Topically, it’s been used for dermatitis, eczema, wrinkles, bedsores, radiation burns, and other skin conditions.  The enhancement of macrophage function aids in healing wounds, although the exact mechanism of this improved healing is uncertain. (Portera. 1997)  Besides that, increases in collagen manufacture have been noticed, resulting in improved tensile strength of the new wound covering.  (Browder. 1988)  The activity in this arena includes the stimulation of growth factors and the release of cytokines, regulatory proteins that mediate the immune response.  (Wei. 2002)  This results in stimulation of fibroblast (giving rise to connective tissue) collagen biosynthesis.

Yeast-based beta-glucans is being taken more and more seriously as an immune health ingredient.  Because it can stand a wide range of body pH, yeast-based product could supplant—or at least enhance—probiotics as a first line of defense against invasion by bacteria and viruses.  (Watson, 2011)

Beyond healing wounds, beta-glucans may prevent the absorption of cholesterol from the stomach and intestine when it is taken orally.  The beta-glucan found in oats led oatmeal makers to petition the FDA to allow such a claim on their labels.  The FDA agreed, as long as the amount is 10% of the product.  (Federal Register. 2002)

By injection, beta-glucans stimulate the immune system by increasing chemicals that prevent infections.  Used in immunotherapy, as in treating certain invasive diseases, beta-glucans incites cytotoxicity (cell toxicity) in neoplastic (abnormal new growth) tissue while leaving healthy tissue alone.  (Vetvicka. 1996)

As with any promising developments in alternative approaches to wellness, funding for additional studies becomes a roadblock.  The promise of beta-glucans, which, because it appears in food cannot be patented as a drug (yet), paints a rosy picture for treating cuts and scrapes, and perhaps for the prevention of contagious diseases and chronic illnesses.

Shift Work and Your Health

overworked-workerRotating shifts causes difficulties because it works in opposition to the body’s normal circadian rhythms, the most influential being the sleep/wake cycle.  There is also the matter of social isolation that comes from working when everybody else is asleep, and vice-versa.  One of the complications of changing shifts is the incidence of gastrointestinal upset.  Shift workers have a notoriously high occurrence of ulcers, based partly on disruption of sleep patterns and partly on the activation of H. pylori infection if it is at all present and waiting for the opportunity to strike.  (Pietroiusti, 2006)  (Segawa, 1987)  Chronic fatigue, untimely sleepiness, and even failure to fall asleep are some other physical interruptions caused by shift work.  Among the worst social perturbations is divorce, an element that hits some jobs more than others, law enforcement being a prime example.

Canada’s Institute for Work and Health delved into this topic and found that night work is associated with an increase in breast cancer among women who work rotating shifts for long durations.  (IWH, 2010)  The etiology of breast cancer is mostly uncertain, but about one fourth its incidences can be attributed to genetic factors.  At least a little blame has been put on light at night and its effect on melatonin, the hormone produced by the pineal gland that communicates information about light to different parts of the body in order to regulate biologic rhythms.  When the eye’s pupil detects changes in brightness—night—it sends the sleep message to the brain by way of melatonin.  When this activity gets stymied, melatonin is not able to exert its anti-cancer character, and the risk of breast cancer is elevated after a prolonged time. (Schernhammer, 2001)   (Hansen, 2001)   Melatonin is a popular sleep aid, especially for those experiencing jet lag, but few have associated it with anti-cancer function.  (Knower, 2012)  An interesting realization in this circumstance is the body’s inability to manufacture vitamin D from exposure to natural light, raising the question of the appropriateness of supplementation.  (Shao, 2012)  Among researchers’ quests is the determination of the actual concentrations of vitamin D in women who have survived breast cancer and whether or not insufficiency is prevalent among sufferers, survivors, and healthy controls.  (Trukova, 2012)  (Blask, 2009)

Little is known about sleep taken at night, and even less about sleep taken during the day, when years of natural law dictate otherwise.  Nobody really knows how much sleep is necessary for optimal health.  But there is evidence that long sleepers and very short sleepers have increased mortality.  (Ferrie, 2007)  The first part of sleep lasts about fifteen minutes, and is labeled as Stage 1.  If you are awakened from this stage, you may even deny having been asleep.  Stage 2 occupies about half of sleep time, yet is the least understood part.  Being deprived of this stage results in almost total sleep loss because this is the part from which other stages develop.  This, by the way, is the stage affected by medications and sleep aids.  Stages 3 and 4 are combined into the slow-wave-sleep stage, differing only by the number of delta waves measureable by an EEG.  Contrasted to Stage 2, this is the one common to most persons, and is the one compensated after long periods of sleep deprivation.  This is the one needed for body repair and the activity of growth hormone(s).  Rapid eye movement (REM) sleep is the best known stage and throughout its duration the body is virtually paralyzed and loses its ability to regulate heat.  Dreams, which are deemed necessary to psychological well-being, occur here.  REM, dominating the late stages of sleep episodes, is strongly influenced by circadian rhythm.   Daytime sleep is normally one or two hours shorter than night time sleep.  REM, therefore, is shortened.  This adds to the alertness problems of the night shift.

A modern concern about shift work is increased risk of type 2 diabetes and the metabolic syndrome, compounded by the possible elevation of cardiovascular jeopardy.  This affects women more than men, but the combination of obesity, high triglycerides, and low HDL cholesterol is common to both.  (Karlsson, 2001)  Years of rotating night shift work are associated with weight gain that comes from failed attempts to eat right and from limited time for exercise.  And to think that all this is precipitated by disturbed circadian periodicity.  Eating on the run and mindless snacking are more common among night workers than their daytime counterparts.  Even if day and night workers had the same major CVD factors, the night workers admit to increased job strain and greater at-work physical exertion, both of which contribute to the altered parameters that incite metabolic syndrome.  (Esquirol, 2009)  In Japan, where the work ethic is ubiquitously strong, different work schedules have been associated with a rise in the incidence of diabetes.  (Morikawa, 2005)  (Suwazono, 2006)  Over the long term, changes are evident not only in daily glucose levels, but also in glycosylated hemoglobin (HbA1c), which measures glucose over an extended time.  (Suwazono, 2009)

Workplace cafeterias commonly close at night.  Workers are then left to their own culinary devices, and that often translates to unhealthy eating habits by virtue of convenience and time constraints.  A healthy work force is a boon to productivity and accident prevention, areas in which companies can demonstrate an interest that supersedes complaining about the opposite.  If a company is reactive, it can get you to the First-Aid station or to the HR person for failure to perform.  By being proactive, it can prevent both while saving money on bandages and the expense of training a replacement.

If there is a best-case scenario for shift work, scheduling a rotation that lasts at least six weeks seems to work by affording enough time to adapt one’s circadian dance to the situation.  There are those who prefer steady nights, but that breed is rare.  If we think adapting to factory work schedules is tough, we should look at those who work in the emergency room.  At least some of us have a scapegoat for tight trousers.

Is Sugar Affecting Your Immunity?

sweet-drinkThere is a metabolic difference between simple and complex carbohydrates.  The simple ones become glucose soon after they are eaten.  The complex ones take longer to turn into sugar and are less apt to spike insulin and cause energy crashes down the line.  But that isn’t the only difference between the two.

Almost forty years ago scientists had an interest in the relationship of diet to health, specifically of sugar intake to immunity.   But their curiosity went past simple sugar to include carbohydrates other than glucose.  The cells that are the backbone of the immune system are supposed to kill, swallow, and dispose of alien bodies, including bacteria, viruses and cancer cells.  Scientists at Loma Linda University in California examined the activity of neutrophilic phagocytes (cells that dissolve the enemy) after subjects ingested glucose, fructose, sucrose, honey, or orange juice and found that “…all significantly decreased the capacity of neutrophils to engulf bacteria…”  (Sanchez, Reeser, et al. 1973)  Looking more closely, the researchers also discovered that the greatest effects occurred within the first two hours after eating, but “…the effects last for at least 5 hours.”  (Ibid.)  If there is any promise, it’s that the effects can be undone by fasting from added sugars for the next two or three days.

At the start of the twentieth century, Americans consumed only about five pounds of sugar a year.  By the fifties, that had grown to almost 110 pounds a year, and to more than 152 by the year 2000.  Corn sweeteners account for 85 of those pounds.
(USDA Economic Research Service, http://www.usda.gov/factbook/chapter2.pdf )  America’s sweet tooth increased 39% between 1950 and 2000 as the use of corn sweetener octupled.

Although the cited study is decades old, its message is contemporary. HFCS began replacing sugar in soft drinks in the 1980’s, after it was portrayed by marketers as a healthful replacement for demon sugar.  It didn’t hurt the industry that it cost less, either.  The biological effects of sugar and HFCS are the same, however.  Neither has any food value—no vitamins, protein, minerals, antioxidants, or fiber—but they do displace the more nutritious elements of one’s diet, and we tend to consume more than we need to maintain our weight, so we gain.

Even though the number of calories from the glucose in a slice of bread or other starch is the same as that from table sugar (half fructose and half glucose), they are metabolized differently and have different effects on the body.  While fructose is metabolized by the liver, glucose is metabolized by every cell in the body.  When fructose reaches the liver, especially in liquid form (as in soda), it overwhelms the organ and is almost immediately converted to fat.  (Taubes. 2011)

Innate immunity is that which occurs as part of your natural makeup and defends you against infection by other organisms.  Short-term hyperglycemia, which might come from a pint of vanilla, has been found to affect all the major components of the innate immune system and to impair its ability to combat infection.  Reduced neutrophil activity, but not necessarily reduced neutrophil numbers, is one of several reactions to high sugar intake.  (Turina. 2005)  Way back in the early 1900’s, researchers noted a relationship between glucose levels and infection frequency among diabetes sufferers, but it wasn’t until the 1940’s that scientists found that diabetics’ white cells were sluggish. (Challem. 1997)  More recent study has corroborated the diabetes-infection connection, agreeing that neutrophil phagocytosis is impaired when glucose control is less than adequate.  (Lin. 2006)  Impaired immune activity is not limited to those with diabetes.  As soon as glucose goes up, immune function goes down.

Some folks think they’re doing themselves a favor by using artificial sweeteners.  Once the brain is fooled into thinking a sweet has been swallowed, it directs the pancreas to make insulin to carry the “sugar” to the cells for energy.  After the insulin finds out it’s been cheated of real sugar, it tells the body to eat in order to get some, and that creates artificial hunger, which causes weight increase from overeating.   Even environmental scientists have a concern with fake sweeteners in that they appear in the public’s drinking water after use.  You can guess how that works. (Mawhinney. 2011)

Mineral deficiencies, especially prevalent in a fast-food world, contribute to immune dysfunction by inhibiting all aspects of the system, from immune cell adherence to antibody activity.  Paramount among minerals is magnesium, which is part of both the innate and acquired immune responses.  (Tam. 2003)  Epidemiological studies have connected magnesium intake to decreased incidence of respiratory infections, and intravenous administration has shown effective in treating asthma. (PDR. 2000)  But sugar pushes magnesium—and other minerals—out of the body.  (Milne. 2000)  This will compromise not only immune function, but also bone integrity.  (Tjäderhane. 1998)

Zinc has been touted for its ability to shorten the duration of the common cold.  Like magnesium, zinc levels decrease with age, and even tiny deficiencies can have a large effect on immune health, particularly in the function of the thymus gland, which makes the T-cells of the immune system.  Zinc supplementation improves immune response in both the young and the old.  (Haase. 2009)  (Bogden. 2004)  (Bondestam. 1985)  All the microminerals, in fact, are needed in minute amounts for optimal growth and development…and physiology.  Low intakes suppress immune function by affecting T-cell and antibody response. Thus begins a cycle whereby infection prevents uptake of the minerals that could prevent infection in the first place.  Adequate intakes of selenium, zinc, copper, iron plus vitamins B6, folate, C, D, A, and E have been found to counteract potential damage by reactive oxygen species and to enhance immune function.  (Wintergest. 2007)

Who would have viewed something as sweet as sugar as being so hostile? It taste great to eat but has a nasty habit of pushing everything else out.

Cancer And Sugar: How Sweet It Isn’t

sugar-cubes-smTalk about linking sugar to cancer can be confusing. The “facts” are often presented in a misleading manner that can cause anxiety in those who have the disease. Yet, learning about the science behind the connection can help us make educated decisions about nutrition choices for better health. Sugar, or rather glucose, feeds every cell in the body. We need it to produce energy. Even if we eliminate sugar from our diets, our bodies will still make glucose from other sources, including proteins and fats. It’s a little more complicated than meets the eye. Eating lots of sugar forces the body to make more insulin, one of whose properties is to tell cells to grow. For healthy cells, this is good because all cells grow, divide, die and get replaced by new ones. However, cancer cells can be told to grow, too, when the body makes too much insulin (Goodwin, 2002) (Duggan, 2013). So, yes, there can be too much of a good thing. Knowing from the start that sugar in itself is not evil, we can proceed to the science.

A recent study at the University Rey Carlos in Madrid found a mechanism that links obesity and diabetes with cancer, based on gene activity that promotes the manufacture of insulin. Once sugar reaches the intestine a hormone called GIP is secreted. This enhances insulin release by the pancreas. GIP is controlled by a protein known as β-catenin, a suspected oncogene whose activity depends on sugar levels. Oncogenes are those that transform normal cells into cancerous ones, and mutations of the β-catenin gene are implicated in the incidence of colon and ovarian cancers, among others. Normal sugar levels do not induce accumulation of this protein in the nucleus, but diabetes and its characteristic elevated blood glucose levels does, and is associated with increased cancer risk (Chocarro-Calvo, 2012). The suspicion of a sugar-cancer link was investigated in Korea more than half a decade earlier, when physicians closed a ten-year study in which was recorded health parameters from the biennial physical exams of people receiving national health insurance. Adjusting for smoking and alcohol use, investigators found that those with the highest glucose levels had higher death rates from all cancers combined (Jee, 2005). Associations of sugar to cancer were strongest in pancreatic cancer for both genders. This was followed by esophagus, liver and colon cancers for men and by liver and cervix cancers for women. The bottom line is that cancer risk is elevated with increased fasting serum glucose (Ibid.).

For the last twenty years, diabetes rates have grown. Almost twenty-six million Americans are so diagnosed, but another seven million remain undiagnosed. The disease has been around since the Egyptians, whose ancient writings mention frequent urination as a disturbing problem. Not to be left out of the medical world, the Greeks coined the word diabetes two hundred years before Christ, and Indian physicians noted that diabetic urine would attract ants. In Type II diabetes, insulin resistance is the underlying pathology, accounting for most diagnoses.

The grading of obesity according to body mass index (BMI) aligns with disease specificity. The BMI of healthy people is 18.5-24.9. Between 25.0 and 29.9, a person is overweight. Grade I obesity runs from 30.0-34.0; Grade II from 35.0-39.9; and Grade III above 40.0. The sixty-six inch person who weighs four hundred pounds is off the charts. You can compute your BMI by multiplying your weight by 703, dividing by your height in inches, and then dividing by your height in inches once more.  A recent issue of the Journal of the AMA announced that obesity Grades II and III are associated with significantly higher all-cause mortality, and that simple overweight is associated with significantly lower all-cause death (Flegal, 2013). Imagine what a person with a BMI of 64.6 has to anticipate!

Of the cancer-awareness organizations, breast cancer support groups receive much attention, and rightly so because of this cancer’s ubiquity and horrid nature. It was realized years ago that a relationship between breast cancer and sugar intake exists, where insulin carries the onus of induction. Elevated sugar intake causes a rise in insulin. If the body’s regulatory mechanism is overtaxed, insulin levels get out of hand. Those with diabetes are especially susceptible (Seely, 1983). Just being overweight, in the absence of diabetes, is also a risk factor for breast disease (Lof, 2009). Men are not excused from soft tissue disease just by virtue of their gender. Dietary sugars, notably sucrose (table sugar), may present an ill-defined risk in males, but a risk nonetheless for pancreas, prostate, testis and even lung cancers (Burley, 1998) (DeStefani, 1998).

The glycemic index (GI) is a measure of the effects of carbohydrates on blood glucose levels. Foods that break down quickly and release glucose rapidly have a high GI; those that break down slowly and release glucose gradually have a lower GI. Glucose is used as the reference point. In light of this, scrutiny has been given to an association of high-GI foods to colon cancer. Although no definitive conclusions were reached, there is enough evidence to suggest avoiding foods that are more energy-dense (read sugars and simple carbs) than nutrient-dense to prevent colon and other gastric disease (Galeone, 2012) (Tuyns, 1992) (Moerman, 1993).

Cancer cells thrive on sugar (Dell’Antone, 2012) (Sandulache, 2011), and glucose transport is misregulated in active disease.  Tumor cells have shown increased levels of glucose uptake, as seen in diagnostic images that use radio-labeled glucose analogs as identifiers (Adekola, 2012) (Jóźwiak, 2012). To compound the disorder, sugar increases angiogenesis, which is the growth of new blood vessels. That’s the last thing we want for a tumor—a feeding tube. Yes, angiogenesis is required for growth and development of an organism and for the healing of wounds, but it needs to stop there. Anti-angiogenic protocols are being studied as novel therapies (Merchan, 2010) (Brown, 1998) (Airley, 2007).

All sugars and carbohydrates need not be avoided. The healthy carbohydrates include vegetables, fruits, whole grains and legumes. There is debate about the value of grains in the diet, but we have to admit they are sources of fiber, phytochemicals, vitamins and minerals, and compounds yet to be identified. To keep insulin levels at bay, be sure to eat protein, fat and fiber. These work even in the presence of simpler carbs and sugars. Compared to the whole fruit with its fiber, fruit juices don’t make the cut. Limit desserts to a few times a week, dump sodas and other concentrated sugars, and focus on whole foods.

Sweet And Large

sweetnersA corned beef special with extra Russian dressing, a side of cole slaw, and a hunk of New York cheese cake for dessert, chased with a Diet Coke. This was pretty common lunchtime fare for a raft of patrons at a local eatery. Were they looking to cut calories? Or was diet soda merely the rage? If these folks were trying to fight the Battle of the Bulge, they chose the losing faction. If marketing diet soft drinks, they joined the pack.

Not too long ago scientists re-examined the effects of artificial sweeteners on human physiology, prompted, it seems, by the obesity epidemic that is sweeping the country and a considerable part of the Western World. It is presumed that eliminating the cause will also eliminate the effect. The cause in this case has multiple personalities, starting with saccharin, the oldest fake sugar, discovered at Johns Hopkins in the late 1870’s…from coal tar. Sounds yummy, right? Yep, a little waterproofing/shampoo in your coffee gets the day off to a running start, and it’ll even treat dandruff and kill lice. In its infancy, saccharin was featured on drug store shelves as a sugar replacement for people with diabetes. It was put into soda in the 1940’s for those who wanted to limit sugar intake, which was ironic because sugar was limited during World War II anyway. Saccharin is 300 times sweeter than table sugar and has a bitter aftertaste. Cyclamate came out in the 30’s, and was blended with saccharin to improve the flavor. Both were GRAS—generally recognized as safe—at first, in the late 50’s. In the late 60’s, however, cyclamate was abandoned by the U.S. as a carcinogen, and saccharin was viewed with suspicion. Other countries allow cyclamates to this day. Saccharin had received a warning label, but that was removed in 2000 by the Sweetness Act. How adorable! In 2010, the EPA took saccharin off its hazardous chemical list. Did you know this stuff is made from toluene, which has limited carcinogenic potential but still is paint thinner?

Aspartame was stumbled upon when Big Pharma was looking to make a new ulcer drug in the mid 1960’s. A combination of the amino acids phenylalanine and aspartic acid linked to a methanol backbone, aspartame is supposed to be avoided by those with phenylketonuria, a rare inherited metabolic disorder that fails to process phenylalanine, leading to mental retardation and other serious problems. Popular reports cite aspartame as causative of seizures and mood changes, an allegation that is still hotly debated (Magnuson, 2007) (Pediatrics, 1997). Its sweetness parallels that of saccharin.

Neotame, a product of Monsanto’s NutraSweet, is 7,000 times sweeter than sugar. That was approved in 2002. It’s the sweetest child on the block. Acesulfame potassium (K) hit the streets in dry foods in the 80’s and as a general sweetener in ’03. But the hot one these days is sucralose–Splenda®. It’s the most popular artificial sweetener, used mostly in soft drinks, but also in some baby foods (Why?).

What’s this got to do with obesity? For starters, the brain doesn’t appreciate being fooled. As soon as it gets the message that something sweet is eaten it initiates the secretion of insulin by the pancreas to start metabolizing glucose. When there is no nutritive entity to provide glucose, the brain makes you hungry enough to get some. You then eat.

Dr. Yanina Pepino and her team of researchers at Washington University School of Medicine found that sucralose is not an inert ingredient, but one that has a definite effect on blood sugar peaks. When subjects drank a sucralose beverage prior to drinking a glucose beverage, their sugar levels rose 20 percent higher than when they drank plain water before the glucose drink. The analysts related this to enhanced insulin and glucose responses caused by the artificial sweetener (Pepino, 2013), possibly leading to insulin resistance. True sweet taste cues serve to regulate energy balance, while non-nutritive sweeteners may promote increased food intake and consequent weight gain (Swithers, 2010).

Sucralose has chlorine groups replacing hydroxide groups in a glucose molecule, making it an organochloride that is related to some pesticides and plastics. It has the capability of lowering intestinal pH, making it acidic and hostile to beneficent colonic bacteria. Even after stopping sucralose, the changed pH may persist (Abou-Donia, 2008). Isn’t chlorine used in swimming pool and bathroom cleaners to kill bacteria?

Before sucralose hit the market, similar investigations focused on then-current artificial sweeteners, aspartame paramount among them. Where a 1986 project found ambiguity concerning appetite signals (Blundell, 1986), later study found that aspartame-sweetened carbonated water increased appetite in the short term (Black, 1993), implying a subsequent intake of excess energy. While the cheesecake crowd was enjoying its low-cal sodas, scientists were already looking at weight management in a highly homogeneous group of middle-aged women, learning that heavier gals were more likely to use non-nutritive sweeteners than their normal weight counterparts, but that, in the long term, artificial sweeteners were not able to prevent weight gain or help weight loss (Stellman, 1986). As with much of what we ingest, dose makes the difference. Those imbibing up to three artificially-sweetened drinks a day appear more likely to risk overweight and obesity than those who consume none (Fowler, 2008). For those who exercise, the difference is insignificant.

So, now, what’s the worry, insulin resistance or weight gain? Being a little overweight doesn’t automatically translate to type 2 diabetes, but it is one of the risk factors. Daily consumption of diet soda was associated with a 36% greater relative risk of metabolic syndrome and a 67% greater risk of incident type 2 diabetes, compared to non-consumption, in a 2009 report from the U of TX (Nettleton, 2009). Whatever the concern might be, fake sugars stir the soup and promote insulin release (Malaisse, 1998). One of the mechanisms involves faking out the brain, not only with renegade appetite signals, but also with altered reward processing of the sweet sensation that rightfully belongs outside the sphere of artificial sweeteners (Green, 2012). As with all heath topics, the debate goes on because some people remain completely unaffected. And we thought that only Superman was bulletproof. The bottom line is that artificial sweeteners do not activate the food reward pathways in the same fashion as natural ones (Smeets, 2005).
