Whats so special about the phosphorus?
What’s special about the phosphorus in the sardine is that it’s balanced by the calcium. You see, when we make bone, for example, the body uses about equal amounts of calcium and phosphorus. Phosphorus is fairly plentiful in most meats and fishes. So most of us get plenty. But we tend not to get enough calcium to balance it. Sardines and milk are two among the few foods with roughly equal amounts of calcium and phosphorus, the way the body likes it.
