People have some funny ideas about food.
A recent survey found that Americans believe the kind of food they eat is more important for managing weight than the amount. There's an upside to that sort of thinking. On average, the percentage of fat in our diets has decreased from 40 percent to 33 percent over the last 20 years. Unfortunately, many of the health benefits of reduced dietary fat are canceled out by the extra fat around our waistlines. When nutrition experts talk about the most important steps for achieving a healthy weight, eating healthy portions shows up high on the list.
