Certain drugs can negatively impact nutrition by interfering with nutrient absorption or decreasing appetite. Drugs that interact with calcium, magnesium, iron, or zinc can lower absorption of other medications. Medications that alter taste or decrease saliva production can decrease oral intake and appetite. Choosing medications with established efficacy and safety, a low risk of drug interactions, and compatibility with disease states can help prevent malnutrition. Maintaining a nutrient-rich diet with antioxidants, B-vitamins, calcium, fiber, and minerals can also help offset potential nutrient-drug interactions.
