Dr. Oz's green bean endorsement could be hogwash.

Coffee seems to have a starring role in the diet world as of recent, especially the Dr. Oz promoted ‘Green Coffee Bean Extract’. Unfortunately, some recent studies on mice shows that all the hype may just be hype, and that the effects aren’t as great as we have been lead to believe.

Dr. Mehmet Oz, TV show host, claimed that the green coffee is a “miracle fat burner”. Grinding raw, unroasted coffee beans, which are soaked in alcohol to pull out all antioxidants, creates the popular substance found in supplements.

A team of scientists in Australia performed a study recently to test the effectiveness of the active compound found in green coffee beans, chlorogenic acid, by feeding it to mice that consumed a high-fat diet. The 12-week study observed these mice — one group with the chlorogenic acid, and one without. Both groups of mice gained weight. However, the mice that consumed the chlorogenic acid, ended up becoming more insulin-resistant, a harmful result which is associated with type 2 diabetes and high blood sugar.


While mice and people are two different animals, website reviews and health claims have also gone against Oz’s claims. For the time being, we might just stick with our regular morning cup of java, because of recent health benefits discovered.
