I do not advocate any particular diet — the “right” diet seems to vary widely based on ethnic origin, lifestyle, and individual biochemistry. As an extreme example, “The China Study” makes a compelling argument for a vegetarian diet, yet the Inuits historically ate almost entirely meat and remained free of most degenerative diseases.
What can be said, almost with certainty, is the following: Eat real food, organic when possible. By “real” food, I mean food that is recognizable as food. I have a strong opinion about this: If an ingredient list reads like a chemistry experiment, perhaps it is one, and perhaps you are the test subject. Put it back on the shelf. In sending this simple message with your food choices, you encourage food producers to provide more real-food options.
On the organic front, it is true that organic food may not be more nutritious than conventional food, and it is almost always more expensive. But what it does not include — pesticides — can make a big difference in your health. Even grains and beans, if they are conventional, were likely sprayed with pesticides. And standards for pesticides on imported products are more lax than for U.S.-grown produce…. If you can’t afford to buy all-organic, this list identifies the most contaminated fruits and vegetables (aka worth buying organic) and the less contaminated (save your money and go conventional).
Another reason to buy organic is that, due to labeling laws, it remains one of the only ways to avoid genetically modified (GM) foods. These foods have slight differences from the natural foods that your body recognizes — and initial animal studies show significant 1 effects 2 as a result. Yet, these GM ingredients permeate nearly all processed foods and even some conventionally grown, apparently “real” foods, such as corn. The “four horsemen” of GM foods are corn, soy, cottonseed, and canola (EDIT: plus sugar beets and alfalfa). If you look at ingredient lists, you will see these offenders in many forms, such as high-fructose corn syrup, canola oil, cottonseed oil, corn oil, cornstarch, and even lecithin (an emulsifier that is usually soy-based). Other GM foods include some Hawaiian papayas and, soon to come, alfalfa.
