Smart Food Choices for Healthy Aging
If you and your healthcare provider are worried about weight gain, you should choose nutrient-dense foods. These foods give you lots of nutrients without a lot of extra calories.
On the other hand, foods that are high in calories for the amount of food are called calorie dense. They may or may not have nutrients. High-calorie foods with little nutritional value, like potato chips, sugar-sweetened drinks, candy, baked goods, and alcoholic beverages, are sometimes called "empty calories."
