Research Directives

The work of the Jean Mayer USDA Human Nutrition Research Center on Aging at Tufts University (HNRCA) promotes Precision Health Aging with its mission rooted in the understanding that nutrition is a cornerstone of health and a preventive measure against chronic diseases. 

Building on a 45-year legacy of targeting lifestyle and genetics to prevent diseases like diabetes and osteoporosis, the HNRCA is now pioneering a geoscience-infused approach. Geroscience, which studies the relationship between aging and disease, is integral to Precision Healthy Aging. By understanding how aging processes contribute to diseases, we can develop targeted interventions that not only treat but also prevent multiple age-related conditions, thereby promoting a healthier, longer life. This evolution signifies our commitment to decoding the complex interplay of factors influencing aging. By harnessing artificial intelligence and data sciences, we aim to personalize prevention strategies, slow age-related deterioration, and foster a healthier, longer life for each individual. 

This research focuses on extending healthspan – typically defined as the period of life spent in good health, free from chronic diseases – is represented by four directives and success comes from the diverse expertise and collaborative spirit used to tackle the complexities of aging and nutrition. 

• Metabolism & Basic Biology of Aging 
• Diet & Chronic Diseases of Healthy Aging
• Diet & Aging Brain, Sensory Systems
• Precision Nutrition & Healthy Aging
