Is popcorn good for you? What about pizza, orange juice or sushi? Or frozen yogurt, pork chops or quinoa?
Which foods are healthy? In principle, it’s a simple enough question, and a person who wishes to eat more healthily should reasonably expect to know which foods to choose at the supermarket and which to avoid.
Unfortunately, the answer is anything but simple.
The Food and Drug Administration recently agreed to review its standards for what foods can be called “healthy,” a move that highlights how much of our nutritional knowledge has changed in recent years – and how much remains unknown.
With the Morning Consult, a media and polling firm, we surveyed hundreds of nutritionists – members of the American Society for Nutrition – asking them whether they thought certain food items (about 50) were healthy. The Morning Consult also surveyed a representative sample of the American electorate, asking the same thing.
