Americans are eating their weight and more in genetically engineered food every year, a new Environmental Working Group analysis shows. On average, people eat an estimated 193 pounds of genetically engineered food in a 12-month period. The typical American adult weighs 179 pounds.
These figures raise a question: If you were planning on eating your body weight of anything in a year, wouldn’t you want tomake sure it was safe to eat?
Shockingly, virtually no long-term health studies have been done on consumption of genetically engineered food.
And there aren’t likely to be any such studies anytime soon. The government isn’t doing this kind of research and is not requiring it of the food industry. It isn’t even making it possible for independent scientists to do it, since under the law, those who hold patents on genetically engineered food get to decide in most cases what testing can – and cannot – be conducted.
As a result, the jury is still out – in fact, it hasn’t even heard the evidence – on whether genetically engineered food might cause health problems. And the answer to this question will likely remain unclear for years.
So what can consumers do in the meantime? Not much – unless they demand that genetically engineered food be labeled. At least then consumers would know whether the food they buy contains genetically engineered ingredients, and could decide for themselves if this is what they want for themselves and their families.
This basic right-to-know issue is only going to become more important in the future, because consumption of genetically engineered food is expected to grow substantially.
193 pounds of genetically engineered food is an underestimate
To calculate how much genetically engineered food people eat each year, EWG researchers started with the U.S. Department of Agriculture’s 2011 data on per capita consumption of four foods commonly derived from genetically engineered crops: sugar, corn-based sweeteners, salad oil and “corn products.”
We estimated how much of each of these foods were likely to be genetically modified. We compared the consumption figures with the latest USDA data showing that 95 percent of the sugar beets, 93 percent of the soybeans and 88 percent of the corn grown in the U.S. are genetically engineered. We also applied federal data showing that 79 percent of the salad oil consumed in the U.S. is soybean oil, and 55 percent of the sugar comes from sugar beets.
From these figures, EWG calculated that the average American annually consumes genetically engineered foods in these quantities: 68 pounds of beet sugar, 58 pounds of corn syrup, 38 pounds of soybean oil and 29 pounds of corn-based products, for a total of 193 pounds.
That’s a lot, but it’s likely to be an underestimate, since it does not account for all the genetically engineered foods that people eat. Other foods that commonly come in genetically engineered versions – but are not included in EWG’s calculations – are canola oil, cottonseed oil, papaya, yellow squash and soy products other than soybean oil. (EWG also excluded genetically engineered animal feed that people may consume indirectly by eating meat raised on genetically engineered crops.)
As more genetically engineered crops are approved and grown commercially, the average amount of genetically engineered food consumed would be expected to spike far above 193 pounds a year. EWG considered only three genetically engineered crops, but more than 30 others are currently being tested in field trials, including apples, barley, bell peppers, cabbage, carrots, cauliflower, cherries, chili peppers, coffee, cranberries, cucumber, flax, grapefruit, kiwi, lentils, lettuce, melons, mustard, oats, olives, onions, peanuts, pears, peas, persimmons, pineapple,popcorn, radishes, strawberries, sugar cane, sunflower, sweet potatoes, tomatoes, walnuts and watercress.
While it is unclear how long it may take for these new genetically engineered crops to reach the market, this long list makes it likely that people could be eating two or three times their weight in GE food annually within the next decade.
Children, Hispanics likely eating more genetically engineered food
Some people are likely already eating more than their share of genetically engineered food. Hispanic Americans, for example, who typically eat between 2-to-3 times more corn flour than people of other ethnicities, would be expected to get an extra dose of genetically engineered food in their diet.
Similarly, data show that children eat more corn flour and sweeteners per pound of body weight than adults. Given how much of these ingredients tend to be derived from genetically engineered sources, kids are likely ingesting more genetically engineered food.
Taking a stand for their right to know should be reason enough for people to vote for labeling of genetically engineered foods. Here’s another good reason: Americans are eating their body weight in genetically engineered food every year – and have little idea where it’s coming from. That’s certainly something to chew on.
