A low-protein diet is a diet in which people reduce their intake of protein. A low-protein diet is often prescribed to people with kidney or liver disease. Also for those with inherited metabolic disorders, such as PKU and Homocystinuria. Foods to avoid are any animal byproduct such as meats, eggs, fish, poultry, milk, yogurt, cheese, Pulses, peanut butter and nuts. Foods that are naturally low in protein are vegetables, fruits, bread, cakes, pasta, corn and potatoes. People on a low-protein diet may also be given a protein substitute mixture or minerals and vitamin tablet to keep them healthy. In the United Kingdom, low-protein products and substitutes are prescribed through the health service. Low protein, vegetarian diets have been hypothesized to be linked to longer life.
