"The pharmaco-dynamic substances (those whose action is similar to medications) found in chocolate are responsible for its reputation concerning its abilities. Four of these such substances can be found in chocolate: theobromine, caffeine,
phenylethylamine, and serotonin. They appear in a negligible quantity, but each in infinitely small quantities plays an important role. Theobromine stimulates the central nervous system, facilitates muscular efforts, as well as having diuretic and cardiotonic action. It is an orexigan (appetite stimulator). Caffeine increases resistance towards fatigue, favorises intellectual activity, and increases watchfulness. Concerning phenylethylamine, it has a chemical structure similar to
amphetamines and therefore contains psycho-stimulating properties. Serotonin, on the other hand, is a neurotransmitter (substance freed by the nerve endings) in the cerebral cortex--its quantity is often found to be lower during certain nervous depression states. The serotonin found in chocolate helps correct its initial loss. Likewise, the caffeine and saccharose stimulate the body's stimulation of serotonin. Finally, due to the pleasure it offers, chocolate stimulates endorphin secretion thus procuring naturally the same effects as opium. With this description of chocolate's chemical composition, it's never-ending list of vertues are easily explained."
"The pharmacologically active constituents of chocolate include theobromine, a caffeine-like inhibitor of cyclic AMP phosphodiesterase, anandamide, the natural ligand for the receptor activated by cannabis, and phenylethylamine, the product of decarboxylation of phenylalanine. Phenylethylamine appears to be the natural ligand for the receptor stimulated by amphetamines, and is an effective antidepressant, for example relieving some of the effects of high progesterone levels. Chocolate craving and addiction has been directly linked to phenylethylamine."
