Genetically Modified Food Products

Many people don't realize that genetically modified food products are in the supermarket now. In fact, most processed food contains genetically modified ingredients. One of the reasons to eat organic food is to avoid these products.

If you buy your food at supermarkets or restaurants, you eat genetically engineered food. An estimated 70% of processed food sold in the United States contains genetically modified ingredients.

Genetically modified foods are not labeled. The only way to avoid them is to buy food labeled "100% USDA Organic" or to use the shopping guide linked below.

Corn and Soy

In the U.S., 88% of corn and 94% of soy is genetically modified (as of 2010). Because these are two of the most common ingredients in processed food, most processed food will contain one or both.

Soy appears in your food as soy flour, oil, protein, and dozens of additives; corn as cornmeal, oil, corn syrup (used almost universally in place of sugar, such as in soda pop), and dozens of additives.


In 2009, genetically modified sugar beets were introduced in the U.S. An estimated 95% of sugar beet farmers grew genetically modified sugar beets in 2009. Nearly all U.S. beet sugar is now from a genetically modified source.

Beet sugar makes up half of the refined sugar in the U.S. Like corn and soy, refined sugar is found in the majority of processed foods.

Food Additives

Many of the food additives used in processed food are from genetically modified sources, or even, like aspartame, produced by genetically modified bacteria.

What's Wrong With Genetically Modified Food?

None of these crops were engineered for better nutrition, taste, or yield. Almost all (99%) were created to tolerate herbicide--to survive a lethal dose of the seed manufacturer's proprietary herbicide, which the farmer is required to buy along with the seed--and/or to manufacture its own insecticide. (Less than 1% of GM crops--zucchini, squash, and papaya--are modified for virus resistance.)
