Detoxification activity of bioactive food compounds against ethanol-induced injuries and hangover symptoms: A review

Alcohol drinking is a popular activity among adolescents in many countries, largely due to its pleasant, relaxing effects. As a major concern, ethanol consumption put the drinkers at risk of nutrients' deficiency due to the disordered eating, anorexia, and malabsorption of nutrients. Moreover, alcohol drinking may lead to the development of hangover symptoms including diarrhea, thirsty, fatigue, and oxidative stress. A broad range of functional food components with antioxidant and/or anti-inflammatory properties including pectin, aloe vera polysaccharides, chito-oligosaccharides, and other herbal components have been explored due to their detoxification effects against ethanol. The underlying anti-hangover mechanisms include reducing the intestinal absorption of ethanol or its metabolites, increasing the activity of ethanol metabolizing enzymes, development of fatty acid β-oxidation in mitochondria, inhibition of inflammatory response, blocking the target receptors of ethanol in the body, and possession of antioxidant activity under the oxidative stress developed by ethanol consumption. Therefore, the development of bioactive food-based therapeutic formula can assist clinicians and also drinkers in the alleviation of alcohol side effects.
