Nutrition Related Diseases

The kidneys’ main job is to filter wastes out of your blood to make urine. They balance the salts and minerals—such as calcium, phosphorus, sodium, and potassium that circulate in the blood. Your kidneys also make hormones that help to control blood pressure, make red blood cells, and assist in keeping your bones strong.

Kidney disease may lead to kidney failure. If your kidneys fail, you will need dialysis or a kidney transplant to maintain your health.

Beat Dieticians can assist you with managing CKD by recommending adjustments to your diet and lifestyle. We are skilled in developing an eating plan that considers individual food preferences, level of physical activity as well as special needs to assist you in reaching your goals. Our goal is to address nutritional concerns while protecting kidney function.
