Older Americans are staying more active in sports, travel and social activities, so maintaining a good diet is important.

The American Institute for Cancer Research has published a new booklet that offers recipes and information on good nutrition and how to stay healthy during the later years of life.

"Be Your Best: Nutrition After 50" focuses on the changing nutritional needs of older people, including the need for fewer calories and more of certain vitamins, minerals and other nutrients.

The publication also explains that making sound nutritional choices, even later in life, can mean decreased chances of cancer and other health problems. Copies are free.
