The fruity flesh closest to the rind of a watermelon causes blood vessels to expand and contract, making it a natural aphrodisiac.
In Ancient Greece cheese was thought to be a powerful aphrodisiac because it contained high levels of tyrosine, which helps increase serotonin levels in the brain. The science behind the claim is that tyrosine helps to boost dopamine levels in the brain, which can lead to increased arousal and improved mood. Additionally, eating cheese has been found to raise testosterone levels in both men and women, which can also lead to an increased libido.
