Healthy people, healthy planet: a flexitarian approach to sustainable healthy diets (self-study course)

This self-study continuing education course, which was approved by the Commission on Dietetic Registration (CDR) to offer 2 CPEUs, provides an overview of the EAT-Lancet Commission’s planetary health diet, a largely plant-based flexitarian diet; discusses the principles of a flexitarian diet; describes the nutritional advantages of a flexitarian diet; examines the health and environmental benefits of a flexitarian diet; and provides strategies RDNs can use when counseling their clients on implementing a flexitarian diet.
