Chocolate is also known to brighten the skin, to the extent that many have even applied chocolate to their skins during their spa sessions. It is believed that vitamin A and E in chocolate helps keep in the skin's moisture, thereby slowing the process of aging and wrinkling. Magnesium in chocolate helps relax fatigued muscles. And if you were wondering why chocolate makes you feel so good, there's an explanation for that, too! The phenylethylamine in chocolate is believed to be responsible for the feel good factor that overcomes those who have just indulged. But nothing's perfect. Phenylethylamine, theobromine and caffeine tend to increase the sugar level in the blood system as well as blood pressure. Chocolate is also a source of energy as a result of its riches of carbohydrate, iron, and vitamins A, D and K, but there is such as thing as too much of a good thing. This kind of energy can trigger ailments such as obesity and high-blood pressure. As our elders have always said, "Whatever you do, do it in moderation.'
