a small tin of sardines contains nearly 20 grams; and one cup of canned beans contains 18 grams. If you consume them in one meal, you likely will have met your protein requirement for the day. But what about the other two meals, or snacks? What happens to all that extra protein? Your body isn’t capable of storing protein the way it stores fat, so the excess is excreted through your kidneys. If you eat a lot of steak, this can give you some very expensive urine!
