It is important to control the portion size of even nutrient-rich foods to avoid consuming too many calories. Most people need fewer calories as they grow older and their activity level decreases.

Although older adults still need plenty of fruits and vegetables, whole grains and fiber, they need to add or subtract a few things from the diet they followed earlier in life.
