Prevention of Diet-Related Diseases and Disparities

Importance of Preventing Diet-Related Diseases and Disparities

Diet-related illnesses including cardiovascular diseases, Type 2 diabetes, and certain cancers are the leading source of poor health in the United States. These illnesses also negatively affect worker productivity, military readiness, healthcare spending, and health disparities. Food insecurity and diet-related illnesses often co-exist. Both are interrelated with challenges and opportunities in the use of natural resources. Across all life stages, research, education, Extension, and innovation could potentially improve understanding of the various factors contributing to the prevention of diet-related diseases and disparities.

Precision nutrition is a new concept that aims to harness emerging findings from nutritional science into meaningful and clinically relevant dietary recommendations for individuals and population sub-groups. Nutrition science encompasses research examining multiple synergistic levels of influence: dietary habits, genetic background, health status, microbiome, metabolism, food environment, physical activity, socioeconomics, psychosocial characteristics, and environmental exposures, among others. Precision nutrition, like precision medicine, aims to capitalize on the exponential growth that is occurring in technology, genomics, proteomics, and metabolomics platforms along with personalized and environmental sensors and other big-data resources.

 

NIFA’s Impact

NIFA recognizes that nutrition could be one of the most cost-effective approaches to address many of the societal and economic challenges faced across the globe today. NIFA’s nutrition efforts are grounded in the Dietary Guidelines for AmericansPhysical Activity Guidelines for Americans, and other federal food and nutrition guidelines and priorities including The President’s Make America Healthy Again initiative. NIFA partners with the Land-grant University System and government, private, and nonprofit organizations to support science to advance understanding of what is in the foods and beverages we produce and how do our products best serve their final users either humans or animals. The agency also invests in developing nutrition scientists across all stages of professional development and building their capacity to work across  disciplines and entities to advance nutritional sciences research, policy, and practice.

 
Relevant NIFA Programs
Relevant Federal Collaborations

National Institutes of Health

In collaboration with the National Institutes of Health (NIH), NIFA developed and funded innovative joint funding announcements (e.g., PAR-18-727PAR-15-024RFA-DK-20-007RFA-DK-20-005) to advance our understanding of food specific molecular profiles, and biomarkers of food and nutrient intake and dietary exposure. Using a complex of “omics” methods, these findings help us better understand factors influencing inter-individual variation in response to foods and food groups recommended by the Dietary Guidelines for Americans, informing both individual and population federal precision nutrition messaging for healthier food and beverage intake. This program is not currently accepted new proposals but has two active awards. 

 

Prevention and Screening Nutrition Relevant Federal Resources

NIFA works with colleagues at the U.S. Department of Veteran Affairs (VA) and the U.S. Department of Health and Human Services (HHS) to prevent and screen for nutrition relevant risk factors during cancer prevention and treatment. This includes compiling and elevating relevant resources such as the following:

 

Federal Food as Medicine Collaborative

NIFA is a part of the HHS led Federal Food as Medicine Collaborative and has helped elevate relevant NIFA assets to support food as medicine initiative including but not limited our supports within prevention of diet-related diseases and disparities as outlined above, food and nutrition securitynutrition educationlocal and regional food systems, and food loss and waste, along with consultation on relevant GusNIP resources and connections.

 

Women’s Health

As part of a broader USDA team, NIFA collaborates with federal partners including but not limited to the Department of Defense, the Department of Health and Human Services, and the Department of Veterans Affairs on advancing women’s health research and innovation. To help advance women’s health, NIFA modified its flagship Agriculture and Food Research Initiative (AFRI) to call attention for the need for women’s health research, education and Extension. Via AFRI, NIFA sponsored a women’s health-oriented workshop in fiscal year 2024.
