Food and Nutrition Education in Schools Act of 2020 This bill directs the Department of Agriculture (USDA) to establish a Food and Nutrition Education in Schools Pilot Program to award grants to local educational agencies for (1) projects that hire qualified, full-time food and nutrition educators to carry out programs in schools that have the goal of improving student health and nutrition; and (2) projects that fund school gardens or other evidence-based interventions relating to student health and nutrition to create hands-on learning opportunities for students. In awarding grants under the program, USDA must prioritize projects that serve schools or districts (1) in which not less than 40% of students qualify for free or reduced-price meals, or (2) that include neighborhoods with high rates of childhood obesity or other diet-related diseases.
