This sandwich staple has been shown to spruce things up between the sheets. That’s right, in a recent Italian study about 25 percent of people sampled put salami at the top of their aphrodisiac food list. Why? Amorous shape aside, scientists say sticks of salami are actually rich in phenylethylamine, a crush-inducing chemical that gives the brain the feeling of being in love. To tap into this saucy benefit, munch on a tasty antipasto before your big meal.
