Your body needs protein to build and repair muscles and bones and recover from injury. As the body uses protein, a waste product called blood urea nitrogen (BUN) is made. If your kidneys can’t filter waste from your blood well, the BUN level in your blood goes up. If the level gets too high, you can become sick. Because of this, you need to control the amount of protein you eat each day. Use this sheet to help you.
