White chocolate really isn’t chocolate. It’s made from cocoa butter, the substance you get by pressing cocoa beans. Cocoa butter is absent of the cocoa solids used to make chocolate.
Chocolate does contain chemical elements that really can boost your mood and produce a euphoric feeling. Eating chocolate can give one the same feeling as falling in love (however fleeting it may be). This is probably why Valentine’s Day and chocolate go hand in hand.
Eating chocolate can also reduce the symptoms of stress.
