While traditional black coffee is made from roasted coffee beans, green coffee beverages are made using the unroasted, or “green,” coffee beans. Extracts from green coffee beans have demonstrated many health benefits in scientific studies. The main components of green coffee responsible for these benefits appear to be caffeine and chlorogenic acid, a type of antioxidant, although some effects are influenced by factors other than these compounds.
Potential Weight Loss
According to a study published in March 2006 in “BMC Complementary and Alternative Medicine,” daily supplementation of an extract prepared from green coffee beans reduced body fat and body weight in mice, as well as fat composition in the liver. The effect was similar in mice supplemented with isolated chlorogenic acids and caffeine, which suggests that these are the compounds responsible for the effect. Chlorogenic acids found in green coffee can be digested and absorbed by humans, which implies a similar availability as the extract.
