Aphrodisiacs promise enhanced libido and a little more oomph in the bedroom, but most are unsubstantiated, and no natural aphrodisiacs have been approved by the federal Food and Drug Administration.

For instance, zinc is a mineral responsible for the production of sex hormones such as testosterone, and many people are zinc deficient -- so foods high in zinc may be considered aphrodisiacs. Others improve blood flow. In general, anything that promotes good health is likely to improve sexual health in the process.
