Expanding the Menu: The Power of Underutilized Foods in a Changing Climate

Monday, October 13, 2025

-

Proficiency: Intermediate knowledge/experience

Track: Culinary Trends, Foodservice Innovation, & School Nutrition

CPE: 1.5

Description

Climate change and biodiversity loss reduce both the variety and nutrient content of our diets, weakening crop resilience and threatening public health. As biodiversity declines, so does the diversity of essential micronutrients in our foods. Embracing a wider range of crops, livestock, and marine foods can strengthen food security and promote resilient ecosystems. Together, the panelists will equip registered dietitian nutritionists with research and case studies on the importance of diverse diets and food systems, along with actionable strategies to help advance these principles in multiple settings. The panel will delve into nutrient density and dietary diversity, emphasizing the significance of underutilized and Indigenous crops. Research shows that increasing the number of species in our food system, with a focus on the World Food Map’s regional diversity, can enhance nutrient density from the field to the plate. A dedicated discussion period will provide attendees with practical ways to implement biodiversity-focused practices that address climate risks, enhance food security, and promote societal well-being.

Learning Objectives

  • Describe the role of biodiversity in improving nutrient density and resilience within food systems at both the field and plate level.
  • Identify four underutilized species that can enhance dietary diversity and contribute to sustainable food systems.
  • Integrate three actionable strategies for registered dietitians to promote biodiverse food practices in a variety of settings, including schools, communities, and the food industry.

Performance Indicators

  • 13.4.2 Applies knowledge of local and global food markets, food production systems and nutrition regulations.
  • 13.2.7 Examines trends and current issues that impact public and global health from existing, new and reemerging diseases that spread through travel and global trade.
  • 13.3.3 Takes into consideration any social, economic, environmental and health implications when developing programs.
