Diabetes is the leading cause of chronic kidney disease in the United States. When these two conditions occur together -- called diabetic kidney disease or diabetic nephropathy -- managing your diet becomes more complex but also more critical.
Where the Two Diets Agree
- Low sodium -- both conditions benefit from under 2,000mg sodium daily
- Limited processed foods -- processed foods spike blood sugar AND are loaded with sodium and phosphate additives
- Lean protein -- both diets favor egg whites, chicken breast, and fish over red meat
Where the Two Diets Conflict
Whole Grains vs. White Grains
Diabetes guidelines recommend whole grains for better blood sugar control. But whole wheat bread, brown rice, and oatmeal are higher in phosphorus and potassium. For combined CKD and diabetes, white rice, white pasta, and white bread are generally the safer choice with portion control.
Beans and Legumes
Beans are excellent for blood sugar management but are very high in potassium and phosphorus. With diabetic kidney disease, most patients need to significantly limit or avoid beans.
High-Potassium Fruits
Many fruits great for diabetics (citrus, bananas, kiwi) are high in potassium. Stick with low-potassium, lower-sugar options: blueberries, strawberries, cherries, and apples in small portions.
Blood Sugar Management on a CKD Diet
- Keep white rice portions to half a cup cooked
- Choose white bread over whole grain, but limit to 1 to 2 slices per meal
- Pair carbohydrates with lean protein to slow blood sugar absorption
- Monitor blood glucose more frequently when changing your diet
- Work with both your nephrologist and endocrinologist when making dietary changes
