Eating organic food will not make you healthier, according to researchers at Stanford University, although it could cut your exposure to pesticides.
They looked at more than 200 studies of the content and associated health gains of organic and non-organic foods. Overall, there was no discernible difference between the nutritional content, although the organic food was 30 percent less likely to contain pesticides.
The research, published in the journal Annals of Internal Medicine, looked at 17 studies comparing people who ate organic with those who did not and 223 studies that compared the levels of nutrients, bacteria, fungus or pesticides in various foods, including fruits, vegetables, grains, meats, milk and eggs.
Fruit and vegetables contained similar amounts of vitamins, and milk the same amount of protein and fat — although a few studies suggested organic milk contained more omega-3. Organic foods did contain more nitrogen, but the researchers say this is probably due to differences in fertilizer use and ripeness at harvest and is unlikely to provide any health benefit.
