Green Coffee Overview
Green coffee refers to coffee beans that have not been roasted (unlike regular coffee, which is roasted). They are typically a pale green color and have a mild, slightly bitter flavor.
One of the main differences between green coffee and regular coffee is the amount of chlorogenic acid they contain. Chlorogenic acid is a plant compound that is found in high levels in green coffee beans, but it is largely destroyed during the roasting process. As a result, green coffee has a higher concentration of chlorogenic acid than regular coffee.
Green coffee is often consumed as a supplement in the form of capsules, tablets, or powders, and is purported to have a number of potential health benefits. Some research suggests that green coffee may help with weight loss, lower blood pressure, and improve blood sugar control, but more data is needed for more definitive conclusions.
