What to Eat When You Have Stage 1 or 2 Kidney Disease

When you discover that you’re in the early stages of chronic kidney disease (CKD), it’s time to make some lifestyle changes, particularly dietary ones.

Kidneys still work well in stage 1 and stage 2 CKD; they have the ability to remove waste and extra fluid, sodium, potassium and phosphorus. The focus of this type of kidney diet is to make changes that may preserve kidney function, reduce blood pressure and, in people with diabetes, control blood glucose.

Diet recommendations for risk factors associated with the early stages of CKD

There are risk factors associated with early stage kidney disease, many of which can be modified by diet:

  • Hypertension (high blood pressure)control is impacted by diet as well as medication. Decreased intake of high-sodium foods and salt helps lower blood pressure. If you read labels, choose low-sodium products and make meals from fresh foods, you can reduce daily sodium intake. The recommended amount of sodium per day for a person with CKD is 1,500 mg. Another thing that may reduce blood pressure is to increase potassium intake from fruits, vegetables, legumes, nuts and dairy foods. In early stages of CKD, the kidneys can eliminate any extra potassium, so enjoy eating high-potassium foods at this stage.
  • Hyperglycemia (high blood sugar)is a concern for people with diabetes. Uncontrolled diabetes accelerates kidney loss and contributes to artery disease and other diabetes complications. Establish grams of carbohydrates to eat per meal. Learn about carbohydrate counting to help stay within set carbohydrate targets. Include high-fiber, low-sugar foods.
  • Proteinuria (protein in the urine due to losses through the kidneys)is a risk factor for kidney disease progression. People in early stages of CKD with proteinuria may be able to slow down kidney function loss by decreasing protein intake to the recommended daily intake for healthy Americans (0.8 grams/kg body weight). Eating smaller portions of animal-based foods such as meat, cheese, milk and yogurt, and including more vegetarian meals will help you get closer to a healthy protein intake.
  • Dyslipidemia (high total cholesterol, LDL cholesterol and triglycerides)is often present in people with kidney disorders. CKD is a risk factor for cardiovascular disease, so in early stages of CKD, pay attention to your lab results and the fat and cholesterol in your diet. Eat more healthy fats from olive or canola oil, avocado, nuts and seeds. Decrease trans fats, saturated fats, total fat intake from animal fats, hydrogenated fats and baked goods. Reduce high-cholesterol foods, and if elevated triglycerides are a problem, reduce sugars and excess portions of refined carbohydrate foods.
  • Chronic inflammationhas been linked to kidney disease and cardiovascular disease, as well as a diet high in saturated and trans-fats, refined foods and excess sugars. To reduce your chance of chronic inflammation, limit dining out, especially on fast foods. Eat more high-antioxidant foods, such as colorful fruits and vegetables, legumes, nuts and low- or non-fat dairy products.

Other nutritional factors to consider in stages 1 and 2 CKD include adequate vitamin and mineral intake to meet your prescribed Daily Reference Intake (DRI) goals, and decreased or increased calories for weight management. Certain herbal supplements can actually damage the kidneys, so it’s best to avoid them.

Stage 1 and 2 kidney disease: Start eating right

By now you may realize that the diet for early kidney disease is actually a healthy one, with fruits, vegetables, legumes, whole grains, low- and nonfat dairy, lean proteins and low-sodium foods. This kidney diet is very similar to the recommendations in the 2010 Dietary Guidelines for Americans, as well as the DASH eating plan (Dietary Approaches to Stop Hypertension). The main difference is the early stage kidney diet limits meat and dairy to help achieve a moderate protein intake. The DASH eating plan, along with reducing intake of salt and high-sodium foods, has been researched extensively and shown to reduce blood pressure.1 For people with stages 1 and 2 CKD, the DASH diet can help with blood pressure control. A vegetarian diet may also help regulate blood pressure, blood fats and moderate protein intake if you have proteinuria.

Once you’ve gone over the Dietary Guidelines for Americans and the DASH eating plan, begin incorporating a more modest intake of protein if you have proteinuria than recommended in these plans so it is tailored to your individual needs. Follow these steps to get started.

  • Add more fiber from fresh fruits and vegetables, and whole-grains, such as whole grain bread and high-fiber cereal.
  • Limit high-fat dairy, including milk, yogurt, frozen desserts, cream cheese and sour cream.
  • Eat less red meat; instead, have more lean poultry and seafood (limit to 6 ounces or less per day, based on your dietary requirements). When you do eat protein, choose grilled or baked instead of fried.
  • Have fewer processed foods, particularly ones with hidden phosphorus additives.
  • Reduce sodium intake — the average American consumes between 3,300 to 4,200 mg/day while the recommended intake is 1,500 to 2,300 mg/day.
  • Limit alcohol consumption. inquiry
  • Adjust calorie intake to reach a healthy weight. Start by eating in moderation, snacking on fruits and vegetables, and eating an appropriate portion of healthy fats.
  • Choose vegetables without cheese, sauces or fried preparation.

Because there are few symptoms in stages 1 and 2 CKD, you may not feel any different. But even small changes in your diet can have a positive effect on your condition by preserving your kidney function for a very long time. Talk with your doctor and dietitian about what to eat when you are in the early stages of kidney disease.
