Chlorogenic Acid (CLA) has been found to be one of the main protective factors in a variety of recent studies examining the health benefits of coffee - from liver to eye health. CLA is one of the powerful antioxidants found in coffee beans, and is also found in strawberries, blueberries, pineapple, and sunflower seeds.
Chlorogenic acid has been shown to inhibit an enzyme that promotes the formation of glucose (sugar) in the liver. Hence, chlorogenic acid in coffee may be responsible, in part, for the reduction of glycemic disorders like diabetes.
Various studies have also indicated chlorogenic acid slows the absorption of fat from food intake and also activates metabolism of extra fat. Chlorogenic acid is more potent in green coffee beans before they are roasted, but is also found in brewed coffee.
