Washington: As Valentine`s Day approaches, the American Chemical Society (ACS) - the world`s largest scientific society, has released a new Bytesize Science video today featuring five chemistry facts that highlight why chocolate, in moderation, may be good for you.
The video explains how a bar of chocolate contains hundreds of compounds, many with beneficial properties.
Among the video`s "sweet" facts were that chocolate may improve your mood, and not just because of its delicious flavor.
Chocolate contains a number of chemicals that inhibit the breakdown of the neurotransmitter anandamide - sometimes called "the molecule of bliss" - which can block feelings of pain and depression.
Chocolate contains caffeine and theobromine, stimulants that can provide a burst of energy.
According to an article from the ACS` Journal of Agricultural and Food Chemistry, the naturally occurring polyphenols in cocoa - the key ingredient in chocolate - boost levels of HDL, commonly known as the "good cholesterol."
