Foundations of Precision NutritionCornell Course
Course Overview
In this course, you will delve into the emerging field of precision nutrition and discover how biological variations and environmental factors shape individual dietary responses. You'll explore why traditional "one size fits all" approaches are giving way to personalized interventions backed by cutting-edge evidence.
Armed with this understanding, you will master the fundamental concepts and terminology of precision nutrition, building the framework for advanced discussions. You'll trace nutritional science's evolution from general dietary guidelines to today's sophisticated, personalized approaches.
With this foundation in precision nutrition principles, you will explore the complex world of dietary response variations, both within individuals and between different people. You'll examine key factors including genetics, microbiome composition, and metabolic differences, along with environmental influences like lifestyle, culture, and food access.
Key Course Takeaways
- Develop a foundational understanding of concepts in precision nutrition
- Outline the evolution of nutritional studies and explain the shift toward the precision nutrition approach
- Distinguish between intra-individual and inter-individual dietary variation sources
- Analyze how host biology factors influence individual dietary responses
- Evaluate how environmental factors affect nutritional outcomes
- Assess current research on biological and environmental components in precision nutrition

How It Works
Course Authors
Saurabh Mehta is a physician with training and expertise in nutrition, epidemiology, infectious disease, and diagnostics. Dr. Mehta is currently the Janet and Gordon Lankton Professor in the Division of Nutritional Sciences at Cornell University and serves on its executive leadership team. He is also the founding director of the Cornell Center for Precision Nutrition and Health and co-director of the NIH-funded Center for Point of Care Diagnostics for Nutrition, Infection, and Cancer as part of the POCTRN network. Dr. Mehta is the program director of the NIH-supported training program on artificial intelligence and precision nutrition. He also co-leads the Research Coordinating Center for the NIH’s Nutrition for Precision Health Initiative and directs the Program in International Nutrition at Cornell.
The central theme of Dr. Mehta’s research is the interplay between nutrition and disease, including facilitating field-friendly assessment for both and elucidating how nutrition can be used as a modifiable risk factor to improve health and associated outcomes, often in the context of pregnancy and early childhood. This is achieved through a combination of active surveillance programs, the invention of point-of-care diagnostics, and randomized controlled trials primarily in India, sub-Saharan Africa, and Latin America.
Dr. Mehta received his medical degree from the All India Institute of Medical Sciences in New Delhi, India, and followed it up with a doctoral degree in Epidemiology and Nutrition from Harvard University in Cambridge, Massachusetts, U.S. His work has been recognized with multiple awards, including a NIH Technology Accelerator Challenge Prize for Innovative Global Health Diagnostics, the Norman Kretchmer Memorial Award for Nutrition and Development, the Rainer Gross Prize for Innovations in Nutrition and Health, and the SUNY Chancellor Award for Scholarship and Creative Activities.
