Phosphorus helps to maintain a normal pH (acid-base balance) in the body and generates and utilizes energy.lmost all foods contain phosphorus. Particularly rich sources include dairy products (milk, yogurt, ice cream, cheese), meat, poultry, fish, tofu and eggs. Food additives added during food processing can also contribute to phosphorus intake, such as the phosphoric acid found in soft drinks.
