Alcohol and Nutrition
Nutrition is a course that has two purposes: to provide energy and to maintain body structure and function. Food supplies energy and provides the building blocks needed to replace worn or damaged cells and the nutritional components needed for body function. Alcoholics often eat poorly, limiting their supply of essential nutrients and affecting both energy supply and structure maintenance.
Once ingested, food must be digested so it is available for energy and maintenance of body structure and function. Alcohol inhibits the breakdown of nutrients into usable molecules by decreasing secretion of digestive enzymes from the pancreas. Alcohol impairs nutrient absorption by damaging the cells lining the stomach and intestines and disabling transport of some nutrients into the blood. In addition, nutritional deficiencies themselves may lead to further absorption problems. For example, foliate deficiency alters the cells lining the small intestine, which in turn impairs absorption of water and nutrients including glucose, sodium, and additional foliate. Even if nutrients are digested and absorbed, alcohol can prevent them from being fully utilized by altering their transport, storage, and excretion. Decreased liver stores of vitamins such as vitamin A and increased excretion of nutrients such as fat, indicate impaired utilization of nutrients by alcoholics.
The three basic nutritional components found in food--carbohydrates, proteins, and fats--are used as energy after being converted to simpler products. Some alcoholics ingest as much as 50 percent of their total daily calories from alcohol, often neglecting important foods. Even when food intake is adequate, alcohol can damage the mechanisms by which the body controls blood glucose levels, resulting in either increased or decreased blood glucose (glucose is the body\'s principal sugar. As a result, alcohol causes the brain and other body tissue to be deprived of glucose...
