Effective Renal Diabetic Diet

A person suffering from renal diabetes cannot retain the glucose in their system; it will be passed along with the urine even when the blood sugar levels are normal. Loss of glucose through urine, in a renal diabetic occurs due to the poor functioning of the renal tubules.

A diet that controls diabetes and is beneficial to the kidney function should be chosen by a renal diabetic.  It should provide the necessary amount of amino acids and nutrients.

Tips for a Better Renal Diabetic Diet

Routine is very important for a person with renal diabetes. A strict dietary regime with controlled food portions should be maintained. Do not skip any meals or over eat and stick to fixed meal times.


Proteins are the building blocks of the body, but when the kidney function is compromised, the body cannot filter the protein waste namely urea. When this build up happens it can be highly risky for the patient and a renal diabetic diet needs to limit the protein content of the diet.

The amount of proteins allowable in the diet depends on the severity of kidney failure. Consume only lean meat like chicken, white of the eggs and fish. Soy products and legumes are a good source of proteins for the vegetarians.However, if dialysis is the treatment method followed, then one needs to compensate the loss of protein during dialysis and consume a high protein diet.


When the kidney function fails then the potassium starts building up in the body and it can affect the functioning of the heart. Limiting potassium is tough as it is found in most healthy fruits like apples, pears, peaches, and vegetables like tomatoes and cauliflowers.  Choose alternatives like berries, cherries, cabbage, spinach, asparagus and broccoli that are high in nutritional content and low in potassium levels in your diet.


Sodium is restricted in a diabetic meal as it can increase the blood pressure and lead to heart attack. In the case of renal failure, excess of sodium in the body can lead to water retention and swelling. It may result in the inflammation around the lungs and the heart.

The sodium level in the diet depends on the level of kidney function. Avoid canned and processed food to limit your sodium intake. Use alternatives to sodium in your cooking and avoid preserved foods. Ready to cook and instant meals are rich in salt content; hence avoid them at all costs.


Phosphorous aids in the maintenance of the bone health of the body. Dried nuts, dairy products, cereals, and beans are rich in phosphorous. But when the kidney function is affected, the excess phosphorous becomes detrimental to the bone health.

It draws the calcium out of the bones and can lead to extreme cases of osteoporosis. Though, a calcium rich diet can be consumed to negate this effect, it is found that foods rich in calcium also contain high amounts of phosphorous. So, limit the intake or ask your doctor to prescribe a phosphorous binder that limits the absorption of phosphorous by the body.

Even though these general guidelines need to be followed to limit the damage of diabetes with kidney failure, a typical renal diabetic diet needs to be tailor-made depending on the patient’s kidney functioning and diabetes levels.
