Just don't rely on them as your sole source of calcium. Probably the most insidious cause of calcium depletion is an obsession with fast foods. Under ideal circumstances, phosphorus works with calcium to promote a strong structural system. Excessive amounts can wreak havoc.

Regular exercise is a solid investment in good health. Some have a tremendous impact on how well we're able to use the calcium we introduce into our systems. For example, vitamin D aids in calcium utilization. In fact, without vitamin D our bodies would be unable to absorb calcium. The best source of vitamin D is sunshine, but people who work or stay indoors all day or wear clothing that keeps them from the sun may not get enough exposure, nor may individuals who live in smoggy cities, since smog absorbs the sun's ultraviolet rays.
