题目:
People who eat at home most of the time have better nutrition than those who go out to eat , a recent study shows. Cornell University professors Lana Hall and Karen Bunch interviewed(面试,接见) 3900 people in the survey. “People who eat less than 30 percent of their food away from home eat the most nutritiously,” they said.
“In general, Americans don’t have nutrient, except for iron and calcium,” they reported. They have the opposite problem——over—consumption(过度消耗), especially of fat.
The food at many fast food restaurants is often low in vitamins. “People who eat more than 30 percent of total calories away from home eat foods that are generally low in nutrients per calorie,” the professors said. More calories and enough nutrient intake(吸收) are required to achieve.
One of the major health risks(风险) is eating too much fat. The professor found than fat consumption became greater as income(收入) went up. It also went up in houses where the female worked. This is probably because these people eat more highly processed (加工的)foods.
