| If you intake too much protein, you get Nephrosis, (I think thats how it's spelled.), and it literally is.. "foamy" urine. It's just abnormally large amounts of proteins and nitrogen molecules in your urine. I'm not quite sure what the effects are.. maybe it's bad for your liver or kidneys. I'm not quite sure. But you'll know when you are intaking too much proteins if you have foamy, or frothy urine. |
