2. Animal protein
People with kidney problems should stay away from high protein diets. The same also goes for dairy products. This is because milk and cheese contain high levels of protein. This protein is highly acidifying, whether it comes from a goat, sheep, or cow. As a result, the consumption of milk and other dairy products increases calcium secretion in the urine – the body must take calcium from the bones to neutralize the acid in your system before your kidneys get flooded with the excess protein. And as you might suspect, this puts a tremendous amount of stress on your kidneys and “ages” your bones by depleting them of calcium.
