Jessica Todd, a USDA economist, says in a report that about 20% of the improvement in the diets of people surveyed comes from Americans eating out less at fast food places or restaurants. And this particular improvement she says is from an increased awareness on nutrition in picking out food, more choices available, and more nutritional information available to buyers. About one third of U.S. adults or 36% were obese in 2009-2010, according to the Centers for Disease Control and Prevention. This is a large increase from 15% in 1980. Studies show this is now declining gradually with increased public awareness of the risks of poor eating habits, including risks of diabetes.
