Study Links Pesticide to Bee Deaths

David Abel, in “The Boston Globe,” reported on a recent Harvard Public Health study that made a one-to-one link between bee colony collapse disorder and a chemical in the neonicotinoid family, imidacloprid (April 6, 2012, B1).

Before 2006, Abel notes, “the typical bee colony collapse was between 25 and 30 percent”–a figure which has “doubled since then.”  Imidacloprid was first reviewed by EPA in 2008.

One strategy chemical companies use to prevent chemicals from being banned is to claim a study is faulty, that more study is needed.  Bayer, the German chemical company who sells the most imidacloprid, immediately claimed the study flawed in that too much of the chemical was used in the study.  But, Alex Lu, associate professor of environmental exposure biology at the Harvard School of Public Health, said “it took only low levels to cause hive collapse, less than is typically used in crops or in areas where bees forage.”  Most importantly, this study clearly linked bee death and colony collapse to imidacloprid.  In other words, there is no question that there is a one to one link here and that the result is bee death.

Imidacloprid is used increasingly in crops such as corn and soybeans.  In Maine, it’s used on “wild” blueberry barrens.  Bees are exposed to imidacloprid both through nectar from the sprayed plants AND through the high-fructose corn syrup with which they are fed.  Charles Benbook, chief scientist of the Organic Center in Boulder, Colorado, and former executive director of the National Academy of Sciences on Agriculture, warned that what’s happening to bees doesn’t just stop with bees:  “People, especially children, consume a lot of high-fructose corn syrup.  The presence of any pesticides in high fructose corn syrup should be a concern for the general public.”

Neonicotinoids act on an insect’s central nervous system.  What do you think it will do to human nervous systems?  Especially when we are learning more and more each day that very small amounts of these chemicals can do a ton of damage.

The Harvard study showed that after 23 weeks of exposure to low levels of imidacloprid, 15 of the 16 treated hives were dead.  Those exposed to higher levels died first.

EPA officials, after the release of this Harvard study, have moved up in their registration schedule so that they will begin a review of imidacloprid by the end of this year.

Parts of France and Italy banned imidacloprid in 2009, and colony collapse disorder there has been substantially reduced.

Bees are our canaries in the coal mines.

Do not eat corn unless it is clearly organic.  Do not eat soybeans, period.  (I’ll write more on that later.)  In addition, both corn and soybeans are likely GMO’d, which is a whole other set of problems for human health.

 A New Kid on the Block:  Agave Nectar

 

In 2008, Rami Nagel decided to investigate agave nectar, a new kid on the sweetener block.  He discovered that agave nectar first appeared in 1995 at the Natural Products Expo West in Anaheim, California.  Sellers were advertising agave nectar as being an organic, all natural raw food with a low glycemic index; as being kosher; as being  grown in nutrient-rich soils; as being fair-traded; and as being sustainably harvested (Rami Nagel, “Agave:  Nectar of the Gods?,” WISE TRADITIONS, summer 2008, ). 

However, it is now clear that despite advertising hype and mislabeling issues, all commercial agave nectar sold in this country is highly refined fructose syrup like high fructose corn syrup (HFCS).  It is also clear that commercial agave nectar is particularly dangerous for diabetics.  Finally, it is also clear that agave nectar contains high levels of saponin, a toxic steroid derivative which can cause miscarriages, and should have warning labels.

Agave is not a cactus, but a succulent in the lily family.  Agave syrup is made from either the large, starchy root, which is shaped like a pineapple, or from the sap that appears when its bloom appears and is removed.  Both processes happen when the plant is about eight years old.  Both processes use industrialized practices—though the Nekutli company, whose brand is Madhava Agave Nectar 100% Natural Sweetener, claims otherwise.  Nagel notes that Nekutli vacuum evaporates the raw nectar and uses enzymes to hydrolize it, all of which removes the natural salts and amino acids and creates a high fructose syrup (“Agave:  Nectar of the Gods?”). 

Nagel discovered that some traditional people in Mexico do make an agave sweetener, called aquamiel, by boiling down nectar collected from the agave plant, much as we boil down maple syrup.  Nagel writes that this mineral rich syrup is thick and has a “characteristic smell and strong flavor.”  Aquamiel, however, ferments into sour and smelly fermented pulque within 36 to 48 hours.  And, traditionally made pulque is difficult to find, even in Mexico, as locations of the rare sources are closely guarded secrets and as pulque does not transport well (Nagel, “Agave:  Nectar of the Gods?”). 

The commercial development of agave nectar, Nagel learned, may have begun as a way to use waste products from tequila production, which also uses the agave plant (“Agave:  Nectar of the Gods?”).  In any case, refining agave nectar produces very high levels of fructose:  up to 84 percent (“Sugar by Any Other Name,” NUTRITION ACTION HEALTH LETTER, Jan/Feb 2010, page 4). 

This manmade fructose, as is true for HFCS, is “unbound” because it is no longer part of a plant’s other components, like its fiber and nutrients.  And, this manmade fructose has a different chemical structure than natural fructose.  Research is showing that as our bodies do not know how to manage this unbound fructose, they are turning it into fat, particularly fat that settles unhealthily around the abdomen.  In your body, explain Sally Fallon Morell and Rami Nagel in a 2009 article, agave nectar “may cause mineral depletion, liver inflammation, hardening of the arteries, insulin resistance leading to diabetes, high blood pressure, cardiovascular disease and obesity”  (“Worse Than We Thought,” WISE TRADITIONS, Spring 2009, 44-52).

Morell and Nagel interviewed Russ Bianchi, Managing Director and CEO of Adept Solutions, Inc., which is a “globally recognized food and beverage development company.”  Bianchi says agave nectar and high fructose corn syrup are made the same way, by “ `using a highly chemical process with genetically modified enzymes.’ ”  The process also uses “ `caustic acids, clarifiers, filtration chemicals and so forth in the conversion of agave starches’ “ (“Worse Than We Thought”). 

Morell and Nagel also heard from Dr. Martin Stutsman of the FDA’s Office of Labeling Enforcement, who explained that while corn syrup which is treated with enzymes that enhance fructose levels has to be labeled HFCS, the FDA does not require the label “High Fructose Agave Syrup.”  Dr. Stutsman did note that agave should be labeled as “hydrolyzed inulin syrup.”  So, Morell and Nagel conclude that labeling what is clearly a syrup a “nectar” is a misnomer the FDA is ignoring.  They also conclude that the difference between starches in corn and agave, when each is processed the same way, means that “agave syrup labels do not conform to FDA labeling requirements” and that the result is a “deepening” of the “false illusion of an unprocessed product.”  They further conclude that “if a sweetener contains manufactured fructose, it is neither safe, nor natural,” especially at such high fructose levels.

On October 2009, the Glycemic Research Institute (GRI) halted all agave trials, delisted agave, and banned agave products for use in foods and beverages—which means, according to the GRI web site, that “manufacturers who produce and use Agave and Agave Nectar in products are now warned that they can be held legally liable for negative health incidents related to ingestion of Agave” (www.glycemic.com/AgaveReport.htm). 

These actions were taken because diabetics in the test who had ingested agave nectar had life-threatening reactions and had to be hospitalized (Laura Johannes, “Agave Syrup May Not Be So Simple,” “The Wall Street Journal,” 27 Oct. 2009). GRI researchers believe that the “refined fructose in  Agave Nectar is much more concentrated than the fructose found in High Fructose Corn Syrup” (www.glycemic.com/AgaveReport.htm). 

GRI had performed three earlier trials, but none had included diabetics.  The second trial used agave from Western Commerce Corporation in California and researchers discovered that the agave syrup was adulterated with high fructose corn syrup to increase profits.  When the FDA came calling, company officials had left the country with millions of dollars in assets (www.glylcemic.com/AgaveReport.htm).  In the fourth trial that was halted, GRI used agave nectar from Volcanic Nectar, and it included a “significant amount of maple syrup” (Johannes). 

According to Morell and Nagel, yucca species (in the agave genus) contain “large quantities of saponins,” which are “toxic steroid derivatives, capable of disrupting red blood cells and producing diarrhea and vomiting.”  The saponins in agave should be avoided “during pregnancy or breastfeeding because they might cause or contribute to miscarriage by stimulating blood flow to the uterus.”  At the “very least,” conclude Morell and Nagel, agave products should carry a warning label indicating that the product may cause miscarriage” (“Worse Than We Thought”).

Morell and Nagel also warn that “since the FDA makes no effort to enforce food-labeling laws, consumers cannot be certain that what they are eating is what the label says it is.”  It’s a good warning to heed.  Read labels, question advertising claims, google strange ingredients, and share learning.  Remember, too, that labels change, so keep checking them.   And, avoid using products with lots of ingredients with chemical names.  Instead, use local, organic, nutrient-dense, whole foods and do your own cooking.          

For me, Agave Nectar is too risky.  For something sweet, I eat and cook a lot of local, organic fruit.  Honey Crisp apples are here this week!  I grow and gather and freeze organic, local berries for the winter.  Raw, unheated honey (the label should say unheated) from as local as possible is my sweetener of choice, followed by organic maple syrup.  I choose label-specified unheated honey from away if I cannot get local unheated honey.  I use sugar very sparingly for celebratory baked products.

High Fructose Corn Syrup

 Despite the food industry’s attempt to tell us so, all food calories do not have the same impact on our bodies.  Nor are all sugars equal.  Most sweeteners are formed from three different sugars (sucrose, glucose, and fructose), and each has a different impact on the body. 

 Sugars are carbohydrates, and, according to Dr. Natasha Campbell-McBride in GUT AND PSYCHOLOGY SYNDROME (2004), all carbohydrates are made of tiny molecules, called monosaccharides, or monosugars.  Glucose and fructose are monosugars, so do not need digestion.  They enter the gut directly.  Sucrose is a disaccharides, or double sugar, and it and other double sugars (lactose from milk and maltose from starches) require “quite a bit of” digestive work in a healthy body to reduce them to absorbable monosugars.  Unhealthy bodies harbor these undigested sugars in the gut, and an unfortunate chain of disease begins as these sugars feed “pathogenic bacteria, viruses, Candida and other fungi,” which themselves begin to produce toxic substances that “damage the gut wall and poison the whole body” (79-81).        

Most sweeteners have different sugar compositions.  High Fructose Corn Syrup (HFCS) is typically 42-55 percent fructose and 45-55 percent glucose.  Honey is 50 percent fructose, 44 percent glucose, and 1 percent sucrose.  Only raw sugar is 100 percent sucrose  (“Sugar by Any Other Name,” NUTRITION ACTION HEALTH LETTER, Center for Science in the Public Interest, Jan/Feb 2010, page 4).  But, as Sally Fallon Morell and Rami Nagel explain in WISE TRADITIONS (Spring 2009), the type of fructose in HFCS is not the same as fructose from fruit and our bodies do not know how to process it into energy (“Worse Than We Thought,” 44-52).

Industry creates HFCS from corn starch, which largely comes from genetically modified corn.  For an amusing, but serious explanation of how HFCS is made, take a look at the movie KING CORN (2007).  A not-so-funny fact surfaced recently according to Morell and Nagel :  nearly 50 percent of samples of commercial HFCS contained mercury, which was found also in nearly one-third of “55 brand-name food and beverage products where HFCS is the first- or second-highest labeled ingredient” (47).

 Fructose in fruit, report Morell and Nagel, is “part of a complex that includes fiber, fatty acids, vitamins and minerals.”  The fructose in HFCS is a free, unbound fructose with an important chemical difference.  Most fruit fructose is D-fructose, or levulose, but HFCS fructose is L-fructose, an artificial compound which has “the reversed isomerization and polarity of a refined fructose molecule.”  Thus, the fructose in HFCS is “not recognized in the human Krebs cycle for primary conversion to blood glucose in any significant quantity, and therefore cannot be used for energy utilization.”  Instead, HFCS, like all refined fructose sweeteners” is “primarily converted into triglycerides and adipose tissue (body fat).”  

Indeed, report Morell and Nagel, a new study published in the “Journal of Clinical Endocrinology and Metabolism, “found that obese people who drank a fructose-sweetened beverage with a meal had triglyceride levels almost 200 percent higher than obese people who drank a glucose-sweetened beverage with a meal.”  Chronic, high triglycerides, remind Morell and Nagel, cause increased insulin resistance, inflammation, and heart disease (47).

Nancy Appleton and G. N. Jacobs, in WELL BEING JOURNAL, reported that two published studies (2010) from Princeton University demonstrated that HFCS causes obesity in rats The researchers think that HFCS is more fattening than sugar because it is not bound to anything, which, in turn, allows it to be processed in the liver into fat—substantially abdominal fat—a risk factor for high blood pressure, heart disease, diabetes, and cancer.  Sucrose is” metabolized by insulin from the pancreas and is more readily used as an energy source.”  Additionally, HFCS bypasses the body’s ability to create satiety, or feeling full (“High Fructose Corn Syrup and Obesity,” WELL BEING JOURNAL, Sept/Oct. 2010, 9-10).  Morell and Nagel note that since all fructose is metabolized in the liver, the livers of test animals “fed large amounts of fructose develop fatty deposits and cirrhosis, similar to problems that develop in the livers of alcoholics (48).”

Rats aren’t humans.  But epidemiologist Devra Davis in THE SECRET HISTORY OF THE WAR ON CANCER (2007) notes that industry has been very adept at both decrying and promoting animal studies:  “Where animal studies on the causes of cancer exist, industry faults them as not relevant to humans.  Yet when studies of almost identical design are employed to craft novel treatments and therapies, the physiological differences between animals and humans suddenly become insignificant” (xii).  So, Davis argues, dismissing animal studies is a type of reasoning that is both “morally flawed” and “ignores one simple fact:  the same basic structure of DNA is found in all mammals (8)”  Davis writes that she has witnessed in her professional life “the maturing of the science of doubt promotion,” or “the concerted and well-funded effort to identify, magnify and exaggerate doubts about what we could say that we know as a way of delaying actions to change the way the world operates” (xii).  Thus, “treating people like experimental animals in a vast and largely uncontrolled study,” while ignoring data from animal studies showing direct cause-and-effect data, is ”morally indefensible” (8).

Morell and Nagel report that HFCS entered the market in the early 1970s, but the FDA did not grant it GRAS (Generally Recognized as Safe) status until 1996, “after considerable pressure from the industry” (mainly Archer Daniels Midland and Cargill) as negative research begin to emerge.  Nevertheless, “HFCS represents the major change in the American diet over the last forty years” as it has replaced more expensive sugar in most soft drinks and is “increasingly replacing sugar in baked goods, bread, cereals, canned fruits, jams and jellies, dairy desserts and flavored yoghurts.”  This substitution is occurring despite research showing that while refined sugars have “empty, depleting, addictive calories,” HFCS is “actually worse for you” (44-45).

 The Center for Science in the Public Interest (CPSI) notes that industry has added so many sugars to processed foods that “the average American swallows 350 to 475 calories’ worth of added sugars each day,” all of which are empty calories (“Sugar Overload,” NUTRITION ACTION HEALTH LETTER, Jan/Feb 2010, 3-8).  Dr. David A. Kessler, a former FDA commissioner, in THE END OF OVEREATING (2009), focuses on how industry has added sugar, salt, and bad fats to processed foods, which is changing a pattern where “for thousands of years human body weight stayed remarkably stable” (3). 

The HFCS story gets worse.  A team of researchers at the University of California Los Angeles Jonsson Cancer Center released a study on 2 August 2010 revealing that pancreatic tumor cells use fructose to divide and proliferate.  Dr. Anthony Heaney said that tumor cells thrived on glucose, but used fructose to proliferate.  He specifically referred to Americans’ use of refined fructose consumption.  Our use of HFCS has increased 1000 percent between 1970 and 1990 (Maggie Fox, “Cancer Cells Feed on Fructose, Study Finds,” 2 Aug. 2010, Reuters).         

HFCS can cause high blood pressure.  A study from the University of Colorado Denver Health Sciences Center recorded the eating habits of over 4,500 adults to determine that amount of HFCS each was consuming.  Those consuming “more than 74 grams of HFCS (the equivalent of 2.5 servings of soft drinks) exhibited `significantly increased risk of developing hypertension.’ “  Indeed, “the study concluded that HFCS consumption can raise blood pressure in adults with no history of hypertension, independently of any other causes” (“High Fructose Corn Syrup = High Blood Pressure, WELL BEING JOURNAL, March/April 2010, 6).   

 Connections are being made between HFCS and gout.  Fructose increases uric acid, and uric acid causes gout.  A study of about 46,000 men who got “at least 12 percent of their calories from fructose” were” twice as likely to be diagnosed with gout” (“Sugar Overload,” NUTRITION ACTION HEALTH LETTER, Jan/Feb 2010, 7). 

 I found much more information showing that HFCS is a dangerous product that is causing humans significant harm.  It’s also likely that industry knows how dangerous it is, but uses it anyway because it is sweet and cheap.  Remember that industry is legally organized to behave this way.  What you can do is to eat nutrient-dense, organic, local foods to maintain your health.
