There is a significant difference in plasma levels of the free fatty acids (FFA) in habitual coffee drinkers compared with a control group of non-coffee and decaffeinated-coffee drinkers. A significant difference in FFA levels between males and females was found under the same conditions of coffee consumption, in non-coffee drinkers and in decaffeinated-coffee drinkers.
