See all the GMOs you may already be eating

Chipotle announced Monday that the chain will no longer serve food containing genetically modified organisms (GMO), raising the bar for transparency in the United States, where there’s no requirement to indicate the presence of GMO ingredients on food labels or in restaurants. Likewise, biotechnology companies aren’t required to report which genetically modified seeds are used in production.

Yet the use of GMOs is undoubtedly widespread. Since GMOs were approved for commercial use, 
and then first planted into U.S. soil in 1996, their 
production has increased dramatically. More than 
90% of all soybean cotton and corn acreage in the 
U.S. is used to grow genetically engineered crops. 
Other popular and approved food crops include 
sugar beets, alfalfa, canola, papaya and summer 
squash. More recently, apples that don’t brown and 
bruise-free potatoes were also approved by the FDA.

It's also instructive to look at permits granted by the United States Department of Agriculture (USDA) and the Food and Drug Administration (FDA) — the American GMO gatekeepers, together with the Environmental Protection Agency – though it's important to note that not all the issued permits are for crops that are approved for commercial use.
To produce crops commercially, biotech companies apply for "deregulated status", the green light from the USDA to plant and distribute without restriction.
The bar chart below shows all deregulated crops, sized by the number of genetic varieties approved for each. The ten crops in green are currently produced in the United States, and described in detail in the list below.

1. Corn

Genetically modified corn turns up in many different products in the U.S. — and corn on the cob
is the least of it. This crop is used to produce many different ingredients used in processed foods
and drinks, including high-fructose corn syrup and corn starch. But the bulk of the GM corn
grown around the world is used to feed livestock. Some is also converted into biofuels.

2. Soybeans

The second largest U.S. crop after corn, GM soy is used primarily in animal feed and in soybean
oil—which is widely used for processed foods and in restaurant chains. In fact,
often used to make an emulsifier called soy lecithin, which is present in a lot of
processed foods, including dark chocolate bars and candy.


3. Cotton

Much of GM cotton is turned into cottonseed oil, which is used for frying in restaurants and in
packaged foods like potato chips, oily spreads like margarine, even things like cans of smoked
oysters. Some parts of the plant are also used in animal feed, and what's left over can be used
to create food fillers such as cellulose.

4. Potatoes

A new kid on the block, the very recently approved GM crop is resistant to bruising and may
produce less of a cancer-causing chemical, called acrylamide, when exposed to high heat.
It has not yet seen adoption in the food supply, but is expected to be.
