Older people need more protein, and 4 other things

Your nutrition needs change as you get older.  Here are five things recommended at the Silver Sneakers website to increase.

1. Protein--to maintain muscle mass and proper functioning
2.  Calcium--1,000 mg to 1,200 mg per day as you pass age 50
3. Vitamin D-- essential to both bone and muscle health
4. Fiber--need increases as we age
5. Water--your sense of thirst decreases with age, so compensate.
