Nutrition for Diabetics With a Kidney Problem

Poorly controlled blood sugar can lead to kidney damage. High blood sugar interferes with the kidney's filtering abilities, leading to a number of complications. Diabetics with kidney damage must adopt a diet that controls blood sugar and minimizes stress on the kidneys.

Protein

• Breaking down proteins can tax the kidneys. Cutting down protein intake can reduce the burden on already damaged kidneys, according to the American Diabetes Association. Your doctor will advise an appropriate protein intake depending on the severity of kidney damage. You should not take it upon yourself to go on a low-protein diet.

Carbohydrates

• Carbohydrates are necessary for energy and have the biggest impact on blood sugar. Diabetics need to work with a doctor or dietician to formulate a diet that includes the proper amount and right types of carbohydrates. Complex carbohydrates like whole grains and vegetables break down more slowly, while white flour foods and sugary foods break down faster---causing dramatic spikes in blood sugar.

Sodium

• Diabetics also need to watch their sodium intake. High blood pressure will worsen kidney damage. The recommended intake is 2,400 mg or less daily but those with existing problems might need to restrict it even further.

Fluids

• Limit or eliminate alcohol---it raises blood sugar. Avoiding dehydration will benefit those with less severe kidney damage. Dr. Andrew Weil, an integrative medicine expert, recommends six to eight glasses in the form of water or caffeine-free teas. You must restrict fluid intake, however, during end-stage kidney failure, when kidney capacity is only 10 to 15 percent of normal, according to the Mayo Clinic.

Meal Tips

• Eating meals near the same time every day that contain similar portions and amounts of carbohydrates, proteins and fats can also contribute to steady blood sugar, according to the Mayo Clinic.
