    HTN: Food/Nutrient and Medication Interaction Assessment

    Dietitians should assess food/nutrient-medication interactions in patients that are on pharmacologic therapy for hypertension, as many antihypertensive medications interact with food and nutrients.

    • Recommendation Narrative

      • Based on the JNC 7 report, although blood pressure control can be achieved in most patients who are hypertensive, many will require two or more antihypertensive medications.
      • Based on the JNC 7 report, failure to comply with lifestyle modifications and pharmacotherapy may result in inadequate blood pressure control.

      The ADA Hypertension Expert Work Group concurs with the recommendations from the JNC 7, regarding food/nutrient and medication interactions.
