Raw coffee beans provide many health benefits. Unfortunately, they are normally roasted prior to the preparation of the popular beverage, a process that removes most of the beneficial effects. In the last couple of years, however, pure green coffee bean extract has attracted a lot of publicity, thanks mainly to clinical and biochemical studies that have confirmed its effectiveness in promoting weight loss. As a result, it is now widely available to the general public.
Traditional coffee is sometimes used to help with weight loss, but the effect seems to be due to caffeine, a stimulant that temporarily raises energy and mental activity levels. Unfortunately, caffeine can produce unpleasant side effects, such as nervousness, irritability and headaches. It can also produce withdrawal symptoms when the intake is reduced or stopped. Green coffee extract contains far less caffeine and its effects seem to be due to an entirely different substance.
The active ingredient is thought to be chlorogenic acid. Despite the name, this compound does not contain chlorine. The name comes from an ancient Greek word meaning "green", and refers to the green color the acid produces when undergoing certain chemical reactions. Roasting the beans destroys chlorogenic acid, which is why normal coffee does not provide the same benefits.
The strong antioxidant properties of chlorogenic acid are well documented. Antioxidants help to suppress oxidation reactions, which, when they take place in the body, can produce harmful free radicals. These are implicated in the aging process and their interactions with DNA can cause cells to become cancerous. Thus chlorogenic acid may help to counteract the effects of aging and prevent the development of cancer.
Most of the recent flurry of interest in green coffee beans has been due to their ability to reduce body fat and help with weight loss. At least one clinical study found a significant effect. Two groups of volunteers, one taking the extract and one taking a placebo, were studied over a number of weeks. At the end of the study the group taking the extract were found to have experienced an average weight loss of 16%.
So how does it work? It seems that chlorogenic acid slows down the rate at which glucose is released from the food we eat. Glucose is a simple sugar that is produced by the breakdown of more complex carbohydrate molecules. It provides the body with energy, but when energy requirements are low it is converted to fat. In other words, carbohydrate intake needs to be balanced by exercise to use up the glucose before it turns to fat. Chlorogenic acid makes this easier by reducing the rate at which glucose is produced.
The benefits of chlorogenic acid may not end there. At least two other effects have been observed. Firstly, it seems to increase the activity of the liver, allowing fats to be metabolized more quickly. Secondly, it appears to help maintain blood sugar at a steady level.
Pure green coffee bean extract is made by soaking raw beans rather than roasting them. This ensures that the active ingredients are not destroyed. The extract can be purchased online in capsule form.
