Which statement best describes the general impact of regular alcohol intake on nutrient absorption?

• A. It has no effect on nutrient absorption
• B. It is limited to water-soluble vitamins
• C. Regular alcohol intake can impair absorption of several vitamins and minerals, including thiamin and zinc
• D. It improves appetite

Answer: (C)

Regular alcohol intake disrupts nutrient absorption broadly. Ethanol damages the lining of the gut and interferes with enterocyte function, which can reduce the uptake of multiple vitamins and minerals. It also contributes to fat malabsorption by affecting pancreatic enzyme activity and bile secretion, so fat-soluble vitamins can be affected as well. Thiamin deficiency is a classic risk with chronic alcohol use due to decreased absorption and depleted stores, and zinc absorption can be impaired, contributing to broader nutritional deficits. Saying there’s no effect or that only water-soluble vitamins are affected misses these widespread impacts, and alcohol does not typically improve appetite.
