Drug Nutrient Interactions
Research has extensively covered the effects of nutrient ingestion on the pharmacological effectiveness of drug dosing. From a nutritional perspective, however, many practitioners are not aware of how the drugs that their patients are already taking, or self-medicating, affect nutrient absorption and the impact it has on the effectiveness of nutritional supplementation. This is especially dangerous for the fast-growing elderly population, who takes more medication than any other population group. (Thomas, 1995)
According to the American Dietetic Association, there are eight classes by which drug-nutrient interactions can be categorized: inappropriate supplementation or diet restriction; drug induced nutrient deficiency; loss of metabolic control interactions (e.g. undesirable altering of glycemic control in diabetic patients); loss of therapeutic efficacy of the drug; incompatibility (e.g. taking certain drugs with alcohol causing toxicity), appetite altering, gastrointestinal, and tube feeding (e.g. administering a broad spectrum antibiotic which causes diarrhea and nutrient depletion).
