A green coffee bean is just a coffee bean that has not been roasted. Coffee beans are green when they are harvested, and turn brown from roasting. There is one other important difference. When they are roasted, an important component is destroyed during the heated process. That is chlorogenic acid.
In Greek, “chloro” means: light green, and “genic” means: formed from. This pertains to the color that is formed when chlorogenic acid is exposed to oxygen.
Besides being green, chlorogenic acid has been studied for its multiple health benefits. In a recent review of 94 scientific research studies on chlorogenic acid, its antioxidant, anti-inflammatory, blood sugar and lipid regulating actions were itemized (1). Further, it was mentioned as a possible supplement for reducing cardiovascular disease, obesity, and cancer (1). Another review of research looked at 5 studies with 364 participants. It concluded that chlorogenic acid intake reduced both systolic and diastolic blood pressure. Larger human studies are warranted (2).
The chlorogenic acid found in a green coffee bean may aid in weight loss, lowering blood sugar and fat levels, and help reduce blood pressure. Further, it may have an antioxidant and anti-inflammatory effect, that could aid in reducing a variety of diseases, such as cancer.
Here are some human studies demonstrating some health benefits of a green coffee bean supplements.
In a small study of 57 subjects were divided into three groups. A chewing gum containing Garcinia cambogia, green coffee extract and l-carnitine was assessed. Results showed it reduced calorie intake of snacks compared to both the placebo chewing gum and the no chewing gum groups (7).
In a study with 203 participants over 6 weeks, blood pressure was reduced with coffee rich in chlorogenic acid (8).
In a study of 40 overweight adults, a supplement with berberine, chlorogenic acid, and tocotrienols was taken for eight weeks. Results showed lower total cholesterol, triglyceride levels, and fasting insulin levels (9).
In a study with 49 females that had dry skin, they ingested coffee polyphenols, including chlorogenic acid, for eight weeks. This resulted in significantly lowered skin dryness. Further measures showed decreased trans-epidermal water loss and improved skin surface pH. Plus, it increased stratum corneum hydration, skin blood flow, and the amounts of free fatty acids and lactic acid in the stratum corneum (10).
Like roasted coffee beans, green coffee bean supplements could be high in caffeine. Thus, large doses could have adverse health effects related to excessive caffeine intake. Click here to read more about possible side effects: WebMD: Green Coffee Beans Link.
