It is possible for a person to survive for many days without food, it is not that easy without water. Water is the most essential requirement of the body.
Water forms about 50 to 70% of the human body. Think of all the blood running through our blood vessels and that liquid part of blood is made up of about 90% water. Water is also used for moisture on our skin, the digestive juices and lubrication of our joints. Many fruits such as oranges, watermelon, grapes and apples contain water. Vegetables such as cucumber, tomatoes, and fresh salads contain water too.
How much should you drink? It is commonly recommended eight 8 ounce glasses of water. Monthly food tip is from Warm Springs Diabetes Program.
