Because CF can cause malnourishment, patients may need up to 50 percent more calories per day than people without the disease. The Mayo Clinic recommends adding antacids, supplemental high-calorie nutrition, special fat-soluble vitamins, extra fiber and extra salt to the diet. A high salt diet can also help with the digestion of fats and protein. Foods high in vitamins A,D,E and K will also help replace the vitamins that the intestines can’t absorb.
