What Are the Benefits of Chocolate?

Chocolate  is the most tasty and popular dessert in the world. The history of its use as food product harks back to the times of Maya and Aztec ancient cultures.

A lot of other influences of chocolate have been studied by scholars all over the world in recent years. What are the most probable benefits of chocolate? Is it really the tastiest medical drug with great nutritional value or one more controversial issue? Lets see.

As everybody knows, chocolate is a product made of cacao tree (cocoa tree, Theobroma cacao) seeds. Originally this plant was spread in Central and Southern America but since 16th century it has been cultivating also in Western Africa and South-Eastern Asia. Pure cocoa production is a long process. After fermentation with bacteria and yeasts, cocoa beans are dried and roasted. Later the extracted nib is liquefied with the production of cocoa liquor separated for cocoa powder and cocoa butter. Cocoa beans contain great amount of different substances with specific biological properties (i.e. antioxidants) with names hard to say and remember:

  • Fats, amino acids, vitamins
  • Flavonoids (epicatechin)
  • Alkaloids (theobromine, caffeine, valeric acid)
  • Phenols (resveratrol)
  • Minerals (potassium, phosphorus, copper, iron, zinc and magnesium)

Popular and well-known influence of chocolate on the nervous system is a general calming effect due to the stimulation of serotonin and endorphins production. These endogenous neuronal mediators act as antidepressants. Furthermore, experiment with snails made by Hotchkiss Brain Institute in Canada showed that flavonoids from cocoa improved the snails’ long-term memories and made them … smarter! Basing on several other studies, the list of dark chocolate positive influence can be extended:
