Q. Do I really need to drink eight glasses of water a day to stay healthy? I just can't seem to drink that much water!
A. No. There's no scientific evidence to support this often repeated advice. The institute of Medicine's food and Nutrition Board, which develops dietary guidelines, concluded that most healthy people can meet their need for water by letting thirst be their guide. You can get fluids from a variety of sources, including fruits, vegetables, juice, milk, coffee, soda and even beer. But if you're over age 65, you exercise strenuously, you live in a hot climate or you find yourself sweltering in the middle of a heat wave, try to drink extra fluids. --Nissa Simon (AARP Bulletin, June 203, Vol. 54 No. 5)
