Getting adequate nutrition can be a challenge as you get older. With age, the number of calories you need begins to decline. Every calorie you consume must be packed with nutrition in order to hit the mark.
Even then, you may fall short. "As we get older, the body becomes less efficient at absorbing some key nutrients," says Katherine Tucker, RD, PhD, chair of the department of health sciences at Northeastern University in Boston. In addition, the ability to taste food declines, blunting appetite. Some foods become difficult to chew or digest.
