How could diet affect kidney and urinary health?

A Western dietary pattern, which is rich in animal protein and contains low amounts of fruits and vegetables, is associated with an increased risk of kidney disease. Diets that are high in phosphates, salt, and animal fat may worsen kidney function. In contrast, diets high in fruits and vegetables require less filtration capacity of individual nephrons and therefore help to prevent deterioration of kidney function. Diets associated with good kidney health include the DASH diet, the mediterranean-diet, and the vegetarian diet.^{[1] [2]}
