The Spring 2023, College of Health Colloquium series focused on the topic of Nutrition. In a context of quickly shifting global climate change conditions and food insecurity, nutrition has become an increasingly important scholarly and public policy topic. This semester's Colloquium series assembled internationally recognized experts who discussed current domestic and international nutritional epidemiological trends, such as overnutrition (obesity) and undernutrition (nutrient deficiency, stunting), and how governments, civil society, the private sector, and researchers are responding. We looked at trends within our most challenged communities in the United States, as well as other emerging middle-income countries, such as Brazil, India, and Mexico, and the World Health Organization's role in response. Our goal was to inform the public about these nutritional challenges through an interdisciplinary population health lens and to discuss potential solutions to improve our health and prosperity.
