Zinc is thought to be good for sexual health (it can help testosterone and sperm production in men) and the No. 1 source is oysters. But really, how often do you eat oysters? Another source: Sesame seeds, says Sass.

Mix them into granola or sprinkle them into a healthy stir-fry, she says.

Some breakfast cereals also contain zinc, such as Kellogg's All-Bran Complete Wheat Flakes. One serving (3/4 cup) has more than 100% of the recommended daily intake.
