A groundbreaking PRiMER study reveals a stark contradiction in medical education: while 94% of primary care residents feel obligated to discuss nutrition with patients, only 14% feel prepared to provide effective counseling. Testing a 3-hour online nutrition course across two medical institutions with 76 residents, researchers found that interactive learning covering macronutrient fundamentals, evidence-based dietary patterns, and motivational interviewing techniques produced significant, sustained knowledge gains and improved attitudes about nutrition counseling responsibilities. The results persisted at 3-month follow-up, demonstrating that brief, targeted interventions can address one of medical education's most critical gaps while fitting into demanding residency schedules.
