The best foods good for kidneys

Sweet potatoes also contain vitamins and minerals, such as potassium, that may help balance the levels of sodium in the body and reduce its effect on the kidneys.However, as sweet potato is a high-potassium food, anyone who has CKD or is on dialysis may wish to limit their intake of this vegetable.Dark leafy greens, such as spinach, kale, and chard, are dietary staples that contain a wide variety of vitamins, fibers, and minerals. Pectin may help reduce some risk factors for kidney damage, such as high blood sugar and cholesterol levels.Apples can also often satisfy a sweet tooth.There are several foods that people should avoid if they want to improve their kidney health or prevent damage to these organs.These include the following:Too much phosphorus can put stress on the kidneys. However, there is a need for more studies to investigate this risk.While the above foods may support a healthy kidney in general, they are not usually the best choices for people with CKD.Doctors will put most people with CKD on a specific diet to avoid minerals that the kidneys process, such as sodium, potassium, and phosphorous.The National Institute of Diabetes and Digestive and Kidney Diseases recommend that people with CKD eat less than 2,300 milligrams of sodium each day.As CKD progresses, people may also need to limit their phosphorous intake, as this mineral can build up in the blood of people with this disease.Choosing the right amount of potassium is also important for people with CKD, as problems may occur when potassium levels get too high or low.People with CKD should aim to eat healthful foods that are low in these minerals but still provide the body with other nutrients.It may also be important for people with CKD to reduce their protein intake and only include small amounts of protein in their meals.
