Diet for People with Diabetic Nephropathy

Diabetic Nephropathy (DN) refers to kidney problems due to diabetes mellitus. These include the excretion of protein in the urine (proteinuria) and slowly developing Renal Failure. A person with this disease need to avoid some foods and limit the amount of others. Waste products that failing kidneys are unable to handle include fluids, protein, sodium, potassium, and phosphorus.

Limit the intake of fluids

The damaged kidneys can not function normally to clean extra fluids, and fluids accumulation may lead to shortness of breath, high blood pressure and swelling of the hands, feet and legs. Congestive heart failure and fluid retention of the lungs can even be caused. Therefore, fluids intake, including all foods that melt to a liquid at room temperature need to be limited.

Restrict the intake of protein

Healthy kidneys can excrete protein byproducts out of the body, but impaired kidneys fail to function well, leading to accumulation of the end product of protein metabolism, urea, in the blood. So it is necessary to restrict protein intake. You need to resort to complete or high-quality proteins, such as eggs, meat, fish, fowl, and some dairy products. Avoid low-quality proteins that are found in vegetables, fruits, starches, breads, and cereals.

Low-sodium diet

Sodium can regulate the fluid balance in our body, and excess amounts of salt in diet may result in water retention, thus leading to high blood pressure, sudden increase in weight, swelling of the body tissues, shortness of breath, etc. Have a low sodium diet and avoid high sodium content foods, such as processed meats, chips or nuts, sauces, and canned foods.

Potassium and phosphorus


High potassium levels in the blood may lead to muscle weakness, cardiac arrhythmias, or even sudden death. Too much phosphorus may cause the bones to become brittle and break easily. Phosphorus rich foods are dairy products, meats, shellfish, bran, whole grain products, beans, nuts, and chocolate.
