Renal Diabetic Diet – Guidelines for Managing Renal Diabetes

A renal diabetic diet is designed to help a person who has renal diabetes. Renal diabetes is a condition in which sugar (glucose) spills into the urine. "Blood glucose levels are normal but the kidney fails to reabsorb the normal amount of glucose back into the blood. Glucose above the threshold is excreted in the urine"(1)

The spilling over of sugar is due to a low-sugar threshold in the kidneys and the kidney’s inability to reabsorb the normal amount of sugar back into the blood.

Renal diabetic diet guidelines

A person with renal diabetes will be given a renal diabetic diet plan to follow. This is a powerful weapon fort the control of this disease. Here are some guidelines that renal diabetes patients should follow:

  1. Reduce your dietary sugar intake to better control the spilling of excess sugar through the urine.
  2. Avoid excess salt. Use herbs and non-salt spices to enhance the flavor of foods. Avoid salt substitutes that contain potassium chloride.
  3. Reduce your intake of high-quality protein foods. Aim for 8 ounces per day (one serving is typically 3 ounces). Avoid processed cheeses and canned, salted or cured meats due to the high salt content.
  4. Limit milk and milk products such as ice cream and yogurt.
  5. Limit or avoid foods high in potassium and phosphorus when following a diabetic renal diet (see below).
  6. Limit daily fruit servings to up to three a day.
  7. Limit vegetables to two servings per day.

Foods high in potassium and the renal diabetic diet

As mentioned in guideline number 5, foods high in potassium and phosphorus should be limited for better kidney health.

People with renal diabetes should avoid or limit these high potassium fruits: apricots, avocado, banana, cantaloupe, honeydew, kiwi, nectarines, oranges, papaya, pears, peaches, prunes and watermelon. Juices from grapefruit, oranges, and pineapple should also be limited or avoided.

Certain vegetables will also need to be limited and they include: artichokes, beans, Brussels sprouts, lentils, lima beans, pumpkin, squash, spinach, and tomato.

By following these guidelines for a renal diabetic diet a patient will find that they can control the disease and lead a productive and full life.
