New Study Finds Corn In Majority Of Fast Food
The next time you order a Big Mac from McDonalds, remember most fast foods contain ingredients derived from corn, according to a new study.
Of the hundreds of fast food servings offered worldwide, scientists could only identify 12 servings of food that could be traced back to something besides corn.A. Hope Jahren, a professor at the University of Hawaii, and Rebecca A. Kraft led the study.
During the study, researchers sampled 480 servings of hamburgers, chicken sandwiches and fries from McDonald's, Burger King, and Wendy's chains in Los Angeles, San Francisco, Denver, Detroit, Boston, and Baltimore.
They found 100 percent and 93 percent of the cows responsible for the hamburgers and chicken sandwiches were fed exclusively corn-based diets.
Researchers also found Wendy's used only corn oil, while McDonald's and Burger King fries seemed to be made using other types of vegetable oils.
Consumers should be warned about how the meat, including cows, served in fast food settings are raised.
Experts say cows and chicken that eat only corn meals or other grains are likely to produce high proportions of omega-6 fatty acids that are not good for health.
Meat from cows grazing on grass tends to contain higher levels of omega-3 fatty acids, which experts say are better for health.
