When you hear the words -- grab a drink for health -- what beverage comes to mind?This time the answer is not wine, it's water. Water is essential to health. Drink at least eight to 10 cups of water or water-based beverages every day. Remember that caffeine-based beverages, like coffee, tea and colas, act as diuretics and you'll lose some of the fluid--alcohol has an even greater effect. So make your drinks--water (bottled or tap), juice or milk.
