Alcohol contains only empty calories and has no nutritional value. it can often contribute to malnutrition because high levels of calories in most alcoholic drinks can account for a large percentage of your daily energy requirements. Even one alcoholic drink a day can contribute to malnutrition.
Your body can’t store alcohol, so it must metabolize it straight away. When you drink alcohol, your body makes metabolizing it a priority over all other metabolic processes. Your body sends alcohol to the liver, which produces the enzymes necessary for the oxidation and metabolism of alcohol.
Not only does alcohol not contain any nutrients of its own, but it can impair your body’s natural ability to store nutrients and vitamins from the food you eat.
