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 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.
