Alcohol consumption causes weight loss
What can be done to reduce the chances of becoming intoxicated if you are drinking alcoholic beverages?

Which statement about alcohol absorption is incorrect? Most alcohol absorption occurs in the stomach. b Food in the stomach slows alcohol absorption by slowing stomach emptying. c Food in the stomach slows alcohol absorption by reducing the amount of alcohol in direct contact with the stomach wall. d Alcohol absorption is rapid so its effects are almost immediate
Most alcohol absorption occurs in the stomach.
