Coffee contains several components which are known to affect human body chemistry. The coffee bean itself contains chemicals which are psychotropic for humans as a defense mechanism of the coffee plants.

One of the coffee component is caffeine, which is a mild stimulant, and in some people coffee drinking enhances alertness, concentration, and mental physical performance. Although it contains a wide variety of substances, it is generally accepted that caffeine is responsible for many of coffee's physiological effects. Because caffeine influences the central nervous system in a number of ways and because a small number of people may be particularly sensitive to these effects. Caffeine is not recognized as a drug abuse and there is no evidence for caffeine dependence. Some particularly sensitive people may suffer mild symptoms of withdrawal after sudden abstention from coffee drinking.

Coffee has a much higher total in-vitro antioxidant activity than other commonly consumed beverages. This is due in part to intrinsic compounds of coffee such as chlorogenic acid, in part to compounds formed during coffee bean roasting such as melanoidins and in part to as yet unidentified compounds. Antioxidant have associated with controlling cell damage. They are also thought to dampen inflammation in the body.

Type 2 diabetes is lower among coffee consumers. Coffee also can reduce risk of gallstones or liver damage, discourage colon cancer, and improve endurance and cognitive function.
