Eating organic foods free from pesticides is strongly correlated with a dramatic reduction in the risk of cancer, according to a groundbreaking study published today in an American Medical Association journal.
The observational study led by a team of French government scientists tracked the diets of nearly 69,000 people. Four years later, those who consumed the most organic foods were 25 percent less likely to develop cancer.
For people consuming the highest amount of organic food, the study found a significantly lower risk of non-Hodgkin lymphoma, all lymphomas and postmenopausal breast cancer. The authors conclude, "Although our findings need to be confirmed, promoting organic food consumption in the general population could be a promising preventive strategy against cancer."
Pesticides linked to cancer include the weed killer glyphosate, the active ingredient in Monsanto's Roundup, and the organophosphate pesticides malathion and diazinon.
"This study provides more evidence suggesting pesticides in food may be harmful," said EWG Toxicologist Alexis Temkin, Ph.D. "Low levels of synthetic pesticides, including those linked to cancer and other serious health problems, are found in some conventionally grown fruits and vegetables. Especially for those items, choosing organics is better for health as well as for the environment."
The scientists focused on 16 different organic food and beverage products, including fruits and vegetables, soy-based foods, eggs, dairy, grains, meat and fish, among others.
Each year, Environmental Working Group releases the Shopper's Guide to Pesticides in Produceâ„¢, which includes the Dirty Dozen list of conventional fruits and vegetables that consistently have the highest levels of pesticide residues, as well as the Clean Fifteen list showing which conventional foods have the fewest pesticides.
"Nobody wants to eat pesticides, and tracking the explosive growth of the organic industry in the U.S. against the flat sales of its conventional counterparts is all the evidence you need to confirm it," said EWG President Ken Cook. "Scientists are sounding the alarm on the risks they pose to human health, and consumers are responding."
