Limit Foods High in Protein
Limit the amount of protein you consume when you decide on a natural detox for kidneys. Actually, the body needs protein (between 56 and 75 grams daily), but diets high in foods like red meat and full-fat dairy have been shown to negatively affect kidney function. This is because digesting and metabolizing these foods produces high amounts of wastes like creatinine, which the body struggles to filter.
