Other than a well-rounded diet supplemented by the standard one-a-day vitamin, there is no recognized specific dietary treatment for metastatic carcinoid in the liver if liver failure or carcinoid syndrome are not present. If a significant degree of liver function impairment is present, a diet used for any cause of liver failure (high carbohydrate, low protein and fat) is indicated along with standard vitamins and extra fat-soluble vitamins (A, D and E). if carcinoid syndrome is present, low dose supplements of niacin and a high protein diet are advised.
