7. Dairy Products
Dairy products are rich in calcium and other nutrients as well as protein. They can be a healthy addition to your diet, but should not be consumed in excess. Too much calcium can lead to kidney stones as your kidneys struggle to dump the excess into your urine.
Overworked kidneys will also not be able to process protein waste and it will reach a dangerous level in your body. Studies have shown that limiting dairy for people with kidney disease can delay the need for dialysis, a process that filters blood when kidneys become unable to.
