Located just below the ribcage, our kidneys are small but mighty; they filter about 50 gallons of blood every single day, removing waste and balancing fluids in our bodies. Kidneys ensure that the body can function normally, and they also manage blood pressure, stimulate the production of red blood cells, and keep bones healthy and strong.
But when kidneys become damaged, they can lose their ability to work and threaten the health of the entire body. Chronic kidney disease happens when kidney damage worsens over several months or years. Several conditions can lead to chronic kidney failure, including high blood pressure and type 1 or type 2 diabetes. About 1 in 7 or 35.5 million adults in the United States have chronic kidney disease (CKD); as many as 90% don’t know they have the disease. More than 1 in 3 people 65 or older have CKD. For individuals with kidney failure, dialysis to remove waste from the blood becomes a lifeline. And proper nutrition can be a vital part of successful treatment.
Nutrition for kidney health
A kidney-friendly diet can reduce stress on the kidneys and minimize complications. A supportive diet for someone with kidney disease or on dialysis can:
- Help control blood pressure and blood sugar
- Reduce waste buildup in the blood (such as potassium, phosphorus, and sodium)
- Support muscle strength and energy levels
- Decrease fluid retention and swelling
Kidney kind foods are those which are low in phosphorus; phosphorus is naturally found in foods with high protein, such as meat, dairy products, and beans. Most people, however, get phosphorus from the extra substances added to food to improve flavor, color, texture, or extend shelf life.
To support kidney function, eat more fresh fruits and vegetables, lean proteins like fish and egg whites, and healthy oils such as olive oil. Stay away from highly processed foods (like deli meats) and drinks (like colas). Research has shown that diets high in fruits, vegetables, and low-fat dairy, and low in sodium, red meat, and sugar are associated with a slower progression of kidney disease.
Top 3 meal planning tips for dialysis patients
Always consult with your doctor to figure out what diet would be best for your health, but these three tips cover what most people with kidney disease should consider:
- Watch potassium and phosphorus levels. High levels of potassium and phosphorus can be dangerous for dialysis patients. Limit bananas, oranges, dairy, and whole grains. Choose apples, berries, rice, and white bread instead.
- Balance protein wisely. Dialysis increases your body’s protein needs, but not all proteins are created equal. Eat high-quality options like chicken, fish, or egg whites. Talk to your dietitian about the right amount.
- Control sodium and fluids. Salt makes you thirsty and can lead to fluid overload. Use herbs and lemon juice for flavor, and measure fluid intake carefully by including soup, ice, and even gelatin.
