The 80% Solution
The most important nutrient - water - is usually left off the recommended food charts.
You should drink about eight glasses (two quarts) of fluid each day. That doesn't mean you have to actually drink all that water. Other liquids count, too, like milk, juices and soups. Products that contain caffeine, like coffee, tea, and carbonated drinks, don't count. Caffeine works as a diuretic, pulling water out of the body. If you drink a lot of bottled water, remember that it probably does not contain fluoride which helps fortify teeth against decay. In fact, the number of cavities has gone up with the popularity of bottled water.
