Anandamide is a cannabinoid, a chemical that hooks up to the same brain receptors that catch similar ingredients in marijuana smoke. Your brain produces some anandamide naturally, but you also get very small amounts of the chemical from cocoa bean products — chocolate. In addition, chocolate contains two chemicals similar to anandamide that slow the breakdown of the anandamide produced in your brain, thus intensifying its effects.

In 2009, a team of nutrition scientists at the Nestle Research Center in Lausanne (Switzerland) produced the still-classic study of the beneficial calming effects. Their results put the amount required to reduce the body's production of stress hormones at 40 grams (about 1.5 ounces) of dark chocolate a day.The chocolate used in the study was 74 percent cocoa, served in two daily doses, 20 grams in the morning and 20 grams in the afternoon, after which the researchers tested the volunteers' blood to measure levels of stress hormones and found the levels of stress hormones dropping among the chocolate eaters, thus making chocoholics everywhere even happier than usual.
