In this lesson from Yale's Low-Cost, High-Nutrition Eating for Graduate and Professional Students course, Dr. Nate Wood offers practical tips for stretching a grocery budget while still choosing nutritious food. He guides viewers through the process of selecting affordable, healthy options directly at the grocery store, connecting the course's earlier lessons on nutrition fundamentals and meal planning to the point of actual purchase. The lecture treats grocery shopping as a skill in its own right, with specific tactics for reading prices, comparing options, and avoiding common budget pitfalls. It is aimed at graduate and professional students managing food costs on a constrained income.
