Foods To Avoid For Optimal Kidney Health

9. Sweet Potatoes

Another potassium-rich food, sweet potatoes can be bad for an individual's kidneys for the same reason dairy and the aforementioned fruits may be bad for them. Healthy kidneys can handle diets rich in phosphorus, protein, and potassium, but kidney health can be better maintained if these nutrients are eaten in moderation. Since individuals with kidney disease are put on special diets to restrict their intake of these nutrients, eating less can help individuals avoid kidney disease altogether.

10. Certain Supplements

We already know potassium, phosphorus, and protein can potentially be harmful to our kidneys, which is why it's important to avoid foods rich in these nutrients. Individuals will also want to avoid high quantities of potassium, for instance, in the form of supplements. Other nutrients can cause problems as well, which is why individuals need to be careful when taking vitamins.
