Is chocolate really an aphrodisiac?

Not really, even though throughout its history, chocolate has been purported as one. Chocolate contains small amounts of a chemical called phenylethylamine (PEA), a.k.a. the "love drug," and it's been linked to the regulation of physical energy, mood, and attention. A tiny amount of PEA is released at moments of emotional euphoria, elevating blood pressure and heart rate. There is no evidence that PEA found in foods increases PEA in the brain – although many chocolate lovers may beg to differ!
