Our food is not the same as 50 years ago

Our food should be our medicine and our medicine should be our food.– Hippocrates

Agribusiness appears to have overlooked Hippocrates’ advice in the quest for profits and quantity over quality. Over the last 50 years key nutrients of fruits and vegetables have declined. In a survey of 43 crops of fruits and vegetables, Davis, Epp, &  Riordan, (2004) found a significant decrease of  vitamins and minerals in foods grown in the 1950s as compared to now as shown in Figure 1 (Lambert, 2015).slide-1-redrawn-from-davis

Not only are there fewer nutrients present in our fruits and vegetables, it is also laced/contaminated with pesticides and herbicides such as glyphosate.  Glyphosate is the weedkiller, Roundup, produced by Monsanto and is now found in almost all non-organic foods as shown in Figure 2.slide2a-foods-with-glyphosate

We are ingesting very low levels of glyphosate in most of our foods which may contribute to the development of illness. On March 20, 2015, the International Agency for Research on Cancer (IARC)–the specialized cancer agency of the World Health Organization–classified glyphosate as probably carcinogenic to humans (Group 2A). Glyphosate also affects our immune system and the healthy bacteria in our gut. Thus, I strongly recommend avoiding glyphosate and other types of herbicide and pesticide contaminated foods. By eating an organic food diet you can reduce pesticide and herbicide exposure by 90%.  Unless you eat only organic foods, you will ingest more pesticides and herbicides at levels unacceptable by the European Union standards  as shown  in Figure 3.

Read the article Glyphosate: Unsafe on any plate: Alarming levels of Monstao’s gyphosate found in popular American foods. It describes the scientific evidence that at even at  ultra-low levels of glyphosate e.g. 0.1 parts per billions (ppb) harm to human health could begin and how much of the foods contain glyphosate.  The Executive Summary is reproduced with permission below:

Executive Summary

A leading FDA-registered food safety testing laboratory has found extremely high levels of the pesticide glyphosate in some of America’s most popular food products. Glyphosate, the active ingredient in Monsanto’s Roundup, is the most heavily used chemical weedkiller in food and agricultural production in human history, as a result of the widespread adoption of genetically engineered crops now grown on more than 175 million acres in the United States (U.S.) and more than 440 million acres around the globe.

New scientific evidence shows that probable harm to human health could begin at ultra-low levels of glyphosate e.g. 0.1 parts per billions (ppb). Popular foods tested for glyphosate measured between 289.47 ppb and at levels as high as 1,125.3 ppb. The testing and analysis was performed by Anresco Laboratories, San Francisco, an FDA registered laboratory that has performed expert food safety testing since 1943.

The laboratory found that well-known products tested for glyphosate, Original Cheerios, for example, measured levels as high as 1,125.3 ppb. Other high levels of glyphosate were found in familiar products such as Oreos, Doritos, and Ritz Crackers, among 29 foods tested. Currently, U.S. regulators allow a very high level of daily glyphosate residue in America’s food. The acceptable daily intake (ADI) limit is set at 1.75 milligrams per kilogram of bodyweight per day (written 1.75 mg/kg bw/day) in the U.S., versus a more cautious 0.3 mg/kg bw/day in the European Union. Tolerances have been set through the submission of corporate-sponsored studies and industry influence on the regulatory process.

New research shows that Roundup causes liver and kidney damage in rats as reflected in changes in the functions of 4,000 genes at only 0.05 parts per billion (ppb) glyphosate equivalent indicating damage.2 Additional studies have found that levels as low as 10 ppb can have toxic effects on the livers of fish and cause significant damage to the livers and kidneys of rats at 700 ppb, which is the allowable level of glyphosate found in U.S. drinking water.

Credible independent, peer-reviewed scientific evidence now shows that the levels of harm to human health could begin at the ultra-low levels of 0.1 parts per billion (ppb) of glyphosate. These groundbreaking new findings that one of the most iconic cereals in U.S. contains levels as high as 1,125.3 ppb should be a wake-up call for all Americans regarding unacceptable levels of pesticide residues in our nation’s food. These findings are especially troubling, considering that the latest independent scientific evidence, during which a team of international scientists re-evaluated the same data previously used by regulators, calls for a much lower ADI to be set at 0.025 mg/ kg of bodyweight per day or “12 times lower than the ADI”6 currently set in Europe and 70 times lower than the level currently allowed by the EPA in the United States. It’s important for individuals and parents to understand that glyphosate contamination cannot be removed by washing and is not broken down by cooking or baking. Glyphosate residues can remain stable in food for a year or more, even if the foods are frozen or processed.

The testing and analysis was performed at the request of FOOD DEMOCRACY NOW!, in coordination with THE DETOX PROJECT, which gathered additional scientific evidence from around the world and included a compendium of independent research on glyphosate that contains Anresco Laboratory’s findings. Based on this new information, FOOD DEMOCRACY NOW! is calling for a federal investigation into the likely harmful effects of glyphosate on human health and the environment and is also seeking an investigation into the relationships between the regulators and the regulated industries, which has resulted in the public being exposed to levels of glyphosate which scientific studies show can be damaging to human health.

Doctor Mike Evans: What’s the Best Diet? Healthy Eating 101

A healthy diet is much more than just focusing on a single food. People focus so often on adding one type of food or eliminating another such as, “Don’t eat ice cream!”, “Eat chia seeds.” “No red meat.” In almost all cases, it is not just one thing, instead a healthy diet is embedded in awareness and healthy life style choices. Watch the superb common sense white board video presentation by Doctor Mike Evans, What’s the Best Diet? Healthy Eating 101. In this short presentation, he summarizes the best practices known. Implement his approach and your health will significantly improve.
