Discussions that mention potassium

Diet & Nutrition board

[QUOTE=stick2013;2987251]I am in need of some help, and not sure if this is where I should be. First of all, I have a friend that is elderly and was very healthy until apparently 2 months ago. Has ended up in the hospital twice in the past 3 weeks. He has Prostrate Cancer(doing radiation now in hospital) Has kidney failure(1 remaining kidney) I am not sure of the working % of his good kidney, High BP, High Cholesterol, and is an insulin dependent diabetic now. The hospital has him on diets for ALL of these.....:eek:

When he comes home(after going to rehab I hope) I will basically be his sole caretaker until he is up and around on his own. I guess my question is WHAT in gods name CAN he eat with all of there special diets.

I basically know...No sugar, no salt, no fat. Anything that looks good, or tastes good is a :nono: . I also know that he needs whole grains, and veggies, beans for protien, and lean meats. But the list for the renal diet contradicts some of the food the food for the diabetic diet.:dizzy:

I am a bit confused, and thinking that he can only eat weeds and seeds, and only a few of those.:jester:

Could some one please help if they have info.

Thanks bunches,


Hi - diabetes, high blood pressure and high cholesterol are a common "triad". Often, people with diabetes are on medication for elevated blood pressure and cholesterol.

As well, diabetes is one of the most common CAUSES of renal failure (called diabetic nephropathy). A significant number of patients with kidney failure are in that position because they did not control their diabetes over the long term. Long term elevated blood sugars can be very damaging to the delicate filtering systems of the kidneys (the nephrons). As renal function declines, the body will retain more water and salt than it should, and metabolic waste products will build up in the blood because the kidneys are unable to filter them and excrete them. These waste products become “toxic” to the body.

Diet is EXTREMELY important in renal failure. In general, patients renal failure, patients need to moderate/restrict intake of protein and any other substances that are regulated by the kidneys - ie. potassium, sodium, phosphorus, fluid.

You are correct when you say that the renal diet contradicts with the diabetes diet. For example - whole grain breads are encouraged for people with diabetes, however, discouraged with renal failure due to their high potassium content.

If you are responsible for your friend's diet, I would highly recommend you seek some professional help. Registered Dietitians (not "nutritionists") are regulated nutrition professionals that are trained in nutrition and therapeutic applications of nutrition. Registered Dietitians must have a 4 yr science degree in nutrition plus a one year internship of clinical training in a health care facility.

All hospitals employ RD's on both an inpatient and outpatient basis. They are the most qualified people to go to for recommendations and meal planning for this situation. You can ask your friend's doctor for a referral. I would be surprised if a dietitian had not already been referred to see your friend in the hospital for dietary education.
