Certain vitamins are essential for the body to function properly. They are organic compounds that are required in small amounts for the body to grow and develop normally. Vitamins are divided into two categories: fat-soluble and water-soluble. Fat-soluble vitamins are stored in the body's fatty tissue and can be found in foods such as dairy products, eggs, and fatty fish. Water-soluble vitamins, such as Vitamin C and the B vitamins, are not stored in the body and must be consumed regularly. ACIDS, which are five letter words, are substances that release hydrogen ions when dissolved in water. They are important components of many biochemical processes and are found in many foods, such as citrus fruits, tomatoes, and vinegar.
