Did you know that diet and lifestyle may have an impact on the efficacy of some medications? When you take a medication to manage a health issue, it should be taken responsibly as directed by your health provider. Sometimes, food interactions with some medications can occur. This happens when something you eat interferes with the drug in your body. Food-drug interaction may reduce or increase a drug’s bioavailability thus altering its effectiveness. That is why it is important to follow your health provider's direction and read product labels carefully. Be aware of what you eat, ensuring the food you eat does not conflict with medications in any way. For example, several common foods that have known interactions with select drugs are grapefruit juice, licorice, and green leafy vegetables.

When you create a MyDiet Profile on Sifter and identify a medication(s), our advanced technology filters in only products that are compatible when taking any of the twelve medication classifications defined below. These practices and principles are grounded in evidence-based research, as shown by the American Dietetic Association, Nutrition Care Manual, and Food & Drug Administration. Every product in Sifter is evaluated by assessing the nutrition panel, ingredient line, and package information. Always follow your healthcare provider's direction and read a product's label before consuming.
