If you think junk food goes directly to your hips, you're right. But it gets worse. It gets into your hips, and into other bones in the body, too. Junk food, or more precisely, food that is high in fat and sugar, robs the skeleton of the building blocks it needs to grow and remain strong to ward off degenerative conditions like osteoporosis. The picture is not pretty.

But I believe that there is no single food every person must consume in order to get a certain nutrient. That is just silly.
