Alcohol is considered a non-nutrient that affects which bodily process?

  1. Digestion

  2. Metabolism

  3. Absorption

  4. Excretion

The correct answer is: Metabolism

Alcohol is classified as a non-nutrient because it provides calories (energy) without essential nutrients like vitamins, minerals, or proteins that the body needs for growth, repair, and overall health. When consumed, alcohol is metabolized primarily in the liver, where enzymes break it down into acetaldehyde, which is then further metabolized into acetic acid before being converted to carbon dioxide and water for elimination from the body. This metabolic process is significant because alcohol can interfere with the metabolism of other nutrients. It can alter how the body metabolizes carbohydrates, fats, and proteins, often leading to a preference for alcohol metabolism over the metabolism of these essential nutrients. This can result in imbalances and deficiencies over time if alcohol is consumed excessively. Additionally, the metabolic burden placed on the liver can lead to conditions such as fatty liver disease or alcoholic hepatitis. In contrast, while alcohol can influence absorption, digestion, and excretion processes, its primary effect as a non-nutrient is most directly related to its impact on metabolism. This is why metabolism is the correct answer in this context.
