Water

A substance that provides health benefits, including hydrated skin, is water. While drinking water helps you meet the eight glasses each day the body requires, an additional source that provides the remaining requirement is food. A guava provides 81 percent of its composition as water. Slice the juicy fruit and serve it in a tropical fruit salad with coconut, pineapple, papaya or mango, or juice it and benefit from its nutrients served over ice.
