Since we do not know their effects on our bodies, I believe it is wise to avoid genetically modified foods. Doing so is not easy but here is some advice. From "What Practical Tips Do You Suggest To Avoid GM Foods?" (Dr. Frank Lipman):
1. Avoid “At Risk” Ingredients
The commonest crops that are genetically modified are Soy (91%) Canola (88%) Corn (85%) Cotton (71%) Sugar Beets (90%) and Hawaiian papaya (more than 50%). So in general, avoid foods with ingredients derived from corn or soybeans. Fortunately there is no GM popcorn or blue or white corn.
2. Avoid Processed foods in general
This is the most reliable way to prevent purchasing GM foods as most processed foods have GMO ingredients in them. Processed foods using products made from corn and soybeans contain the most GM ingredients.
3. Buy Organic
