Great news for those who like honey! Even though honey is really sweet (lots of sugars!), eating it actually helps your health. Univ. of Toronto researchers analyzed 18 well done studies and found that honey improved key measures of cardiometabolic health, including blood sugar and cholesterol levels.

These results are interesting because they contrast with other research finding a high intake of sugars (e.g., sugar, high fructose corn syrup, soda) contributing to obesity, type 2 diabetes, and cardiovascular disease. Unfortunately, most regulatory agencies, including the World Health Organization, the Heart and Stroke Foundation, and the FDA (US Food and Drug Administration), include honey within their definition of free or added sugars. And advise limiting intake.

However, honey is not like other sugars. Honey has a complex composition of organic acids, minerals, vitamins, enzymes, proteins, amino acids, and bioactive substances. Rare sugars constitute around 14% of the sugar content of honey. Raw honey also contains probiotic bacteria.

All sorts of studies (in vitro, animal, clinical) have shown that honey has health benefits for cardiometabolic health. Among these benefits are improvements in body weight, inflammation, lipid profile, and glycemic control.

What kind is best? The Univ. of Toronto researchers found that the best health results are found with consumption of raw honey, clover honey, and robinia honey. In other words, honey that is not processed (raw honey) or from only 1 floral source (e.g., clover, acacia/robinia).

How much is best? The median dose consumed was 40 g or about 2 tablespoons daily, usually added to foods or beverages as a sweetener (e.g., in tea, mixed with yogurt, spread on bread) . Enjoy!

Are all foods contaminated by the herbicide glyphosate? The weed-killer glyphosate, which is in Roundup, keeps turning up in foods - basically in every food studied. Glyphosate is the most widely used herbicide in the world, and its use keeps increasing - which means we are increasingly exposed to more glyphosate residues in foods. What does this mean for our health? Along with other health effects (e.g. endocrine disruption, reproductive effects, alters the gut microbiome), there is increasing evidence that glyphosate herbicides are carcinogenic (cancer causing) - especially linked to non-Hodgkin lymphoma.

Studies detect glyphosate in most adults in the US, including pregnant women. Since glyphosate herbicides are so widely and heavily used by farmers (greater than 88.6 pounds per square mile in the US midwest!!, according to the USGS), then it is difficult to avoid glyphosate residue in foods. The US government is not helping the situation - they have been refusing to test for glyphosate in foods for years, and they have twice raised the allowable glyphosate residue levels in foods when asked to do so by Monsanto (the manufacturer of Roundup). The only way to avoid glyphosate is to eat organic foods - it is not allowed in organic food production. 

A recent Canadian government study looked at whether glyphosate was found in 200 honey samples from western Canada. Glyphosate was detected in 197 of the 200 samples! Even though beekeepers do not use glyphosate in beekeeping, the bees were picking it up in their search for nectar and bringing it back to the hives. Which means whenever one eats the honey, that person is also getting some glyphosate residues. A little here, a little there... we're getting  some everywhere...

Excerpts from an article by journalist Carey Gillam for Environmental Health News:

Weed killer residues found in 98 percent of Canadian honey samples

Study is the latest evidence that glyphosate herbicides are so pervasive that residues can be found in foods not produced by farmers using glyphosate. As U.S. regulators continue to dance around the issue of testing foods for residues of glyphosate weed killers, government scientists in Canada have found the pesticide in 197 of 200 samples of honey they examined.

The authors of the study, all of whom work for Agri-Food Laboratories at the Alberta Ministry of Agriculture and Forestry, said the prevalence of glyphosate residues in honey samples - 98.5 percent - was higher than what was reported in several similar studies done over the last five years in other countries.  ...continue reading "Pesticide Residues In Honey"

Published on Leave a comment on The FDA Has Already Stopped Testing For These Pesticides In Foods

An article points out what we should all be concerned with, but is being ignored - pesticide residues of glyphosate (found in Monsanto's Roundup) and 2,4-D in foods. Glyphosate is the most used pesticide in the world, and both glyphosate and 2,4-D pesticide residues in food are set to really increase with the introduction of genetically modified crops resistant to both pesticides (The farmers can spray the pesticides against weeds repeatedly and the crops won't die - they're resistant to the pesticides, so the crops and foods will contain pesticide residues.). Both pesticides are linked to a variety of health problems.

The FDA, under pressure, started analyzing some foods this year for glyphosate residues, but has already stopped due to "problems". When and if they resume is unknown. It is important to know that pesticide residues at varying levels have been found in many foods (here, here, and here). What this chronic low level exposure does to humans is unknown. The only way to avoid or minimize pesticide exposures is to eat organic foods (here, here, and here).

When reading the following excerpts, note that there are no standards for glyphosate residues in honey in the United States. Research by a FDA chemist and a chemist at the University of Iowa found residues of glyphosate at varying levels with a high of 653 parts per billion in one sample (in honey from Iowa) - which is more than 10 times the limit of 50 ppb allowed in the European Union. Other honey samples tested detected glyphosate residues from under 16 ppb to over 123 parts per billion ppb (in honey from Louisiana). I mention this because pesticide residues are an important issue - because we don't know what chronic exposure to mixtures of low levels of pesticides in foods does to us. To babies and children, to pregnant women, to the elderly, to all of us. The following article excerpts are by journalist Carey Gillam, from The Huffington Post:

FDA Suspends Testing for Glyphosate Residues in Food

Government testing for residues of an herbicide that has been linked to cancer has been put on hold, slowing the Food and Drug Administration’s first-ever endeavor to get a handle on just how much of the controversial chemical is making its way into U.S. foods. The FDA, the nation’s chief food safety regulator, launched what it calls a “special assignment” earlier this year to analyze certain foods for residues of the weed killer called glyphosate after the agency was criticized by the U.S. Government Accountability Office for failing to include glyphosate in annual testing programs that look for many less-used pesticides. Glyphosate is the most widely used herbicide in the world, and is the key ingredient in Monsanto Co.’s branded Roundup herbicide line.

Glyphosate is under particular scrutiny now after the World Health Organization’s cancer experts last year declared the chemical a probable human carcinogen. Several private groups and nonprofits have been doing their own testing, and have been finding glyphosate residues in varying levels in a range of foods, raising consumer concerns about the pesticide’s presence in the American diet.

The FDA’s residue testing for glyphosate was combined with a broader herbicides analysis program the FDA set in motion in February of this year. But the glyphosate testing has been particularly challenging for the FDA. The agency was finally forced to put the glyphosate residue testing part of the work plan on hold amid confusion, disagreement and difficulties ....FDA spokeswoman Megan McSeveney confirmed the testing suspension and said the agency is not sure when it will resume.....Alongside the testing for glyphosate, the FDA laboratories have also been analyzing foods for 2,4-D and other “acid herbicides,” documents obtained from the FDA show. The category of acid herbicides includes five of the top 10 active ingredients used in homes and gardens. Usage of 2,4-D is expected to triple in the coming year, according to the FDA.

McSeveney said glyphosate residues were only being analyzed in soy, corn, milk and eggs and the popcorn samples, while the other foods are being tested for residues of other herbicides. Earlier this year, one of the agency’s senior chemists also analyzed glyphosate residues in honey and oatmeal and reported his results to the agency. Some honey samples contained residue levels well over the limit allowed in the European Union. The United States has no legal tolerance for glyphosate in honey, though the Environmental Protection Agency (EPA) said recently it may set one because of the FDA findings. 

With the testing on hold, it is not clear when the agency might have final results on the glyphosate residue analysis. McSeveney said preliminary results showed no violations of legal tolerance levels allowed for glyphosate in the foods tested. She did not provide details on what, if any, levels of residue were found. Tolerance levels are set by the EPA for a variety of pesticides expected to be found in foods. When residue levels are detected above the tolerance levels, enforcement action can be taken against the food producers.

Though FDA annually tests domestic and imported foods for residues of other pesticides, it never tested for glyphosate before. It has not routinely tested for 2,4-D either, a fact also criticized by the GAO. The FDA testing for 2,4-D residues comes as the use of 2,4-D with food crops is expected to start rising due to the commercialization of new formulated herbicide products that combine glyphosate and 2,4-D. Safety questions have been raised about the combination. But the EPA gave a green light on Nov. 1 to a Dow AgroSciences’ herbicide combination of glyphosate and 2,4-D. The new products are intended to counter widespread weed resistance to glyphosate, and be used with new types of genetically engineered herbicide-tolerant crops.

I've been thinking a lot about pesticides in foods and pesticides in honey since the recent post about untreated lawns and bees. Research finds that untreated lawns (no pesticides of any kind) with their diversity of flowering weeds or "spontaneous flowering plants" (such as clover and dandelions) are actually great pollen and nectar sources for bees. In other words, untreated lawns are great bee habitats! We think of conventional farms as using a lot of pesticides, but that is also true of suburbia with its obsession with "perfect lawns" and gardens, with no weeds allowed. According to U.S. Fish and Wildlife Service: Up to ten times more pesticides per acre are used on suburban lawns than on conventional farms! Perhaps it's time to view clover and other "spontaneous flowering plants" as beneficial wildflowers providing food for bees, and not undesirable weeds that need eradicating with pesticides.

Thus these recent articles about pesticide residues in foods, including honey, caught my eye. Notice that conventional foods have pesticide residues, but not organic foods (or they may have much lower pesticide residues, typically due to contamination from neighboring farms). Honey is tricky - there may be pesticide residues because bees fly to pesticide contaminated areas, and also beekeepers may use pesticides for pest control when caring for their bees and bee hives. The most uncontaminated honey would be from organic beekeepers located in pristine areas, with no industry, farming, or treated lawns nearby, and who do not buy "wax starter comb". Bees forage for nectar and pollen within 2 miles from the bee hive, but may fly up to 7 miles from the bee hive. As an article in Scientific Reports pointed out: "Any agrochemical applied anywhere within a colony's extensive reach can end up back in the hive."

Note that no one knows what the long-term health effects are of ingesting foods daily with low levels of mixtures of pesticides (chronic exposure), and also of ingesting endocrine disruptors. A "cocktail effect" may occur from combined traces of different pesticides - the chemicals may be more toxic when combined than alone. We just don't know. The FDA just started testing for glyphosate residues (glyphosate is the active ingredient in Roundup) in 2016 - and this is the most heavily used pesticide in the world! Currently nearly 300 million pounds of glyphosate are applied each year on U.S. farms. Now add in all the other ways we're exposed to pesticides - both indoors and outdoors  lawns, gardens, farms), even on our treated pets. Something to think about.

A number of Kellogg and Nestle brand muesli cereals were among those tested in the following research. Muesli is a breakfast cereal of rolled oats, perhaps other grains, dried fruit, and nuts.  ...continue reading "Pesticide Residues In Honey and Other Foods"
