Dairy has historically been a contentious food. While some dietitians promote it as being nutritious, wholesome, and high in protein, others would assert that it could be harmful to people's health. Regardless of one's position on the matter, dairy products like milk have a lot of phosphorus and potassium. Both phosphorus and potassium, as was already said, can be challenging for our kidneys to digest. Large amounts of potassium and phosphorus as well as the extra protein included in dairy products cannot be processed by patients with certain types of renal disease. Any of these nutrients that accumulate in the blood might lead to issues with the body's organ systems. Milk made from nuts or rice may be a superior substitute for dairy.
