BATON ROUGE, Louisiana – A new federally funded study will use machine learning to predict how an individual responds to a given diet, allowing physicians to offer patients personalized nutrition prescriptions to improve health and treat chronic diseases.
“Food lies at the epicenter of health and disease. But clinical nutrition is still limited to a one-size-fits-all-approach that far too often fails a large segment of the population,” said Eric Ravussin, Ph.D., Associate Executive Director for Clinical Science at Pennington Biomedical Research Center.
“What we need is precision, the ability to prescribe diets that account for the factors unique to each person, such as their genetics, metabolism, physiology, behavior, even the microorganisms in their body,” said Leanne Redman, Ph.D., Associate Executive Director for Scientific Education at Pennington Biomedical.
Nutrition for Precision Health, powered by the All of Us Research Program will develop a first-of-its-kind algorithm to predict individual responses to food and dietary routines. The study will recruit 10,000 people nationwide from the 1 million U.S. residents who have volunteered their health data for the National Institutes of Health’s All of Us Research Program.
As one of six clinical sites in the nation, Pennington Biomedical, in partnership with LSU Health New Orleans and the National Institute of Diabetes and Digestive and Kidney Disease-Phoenix, plans to enroll more than 2,000 participants in three study modules. Drs. Ravussin and Redman are the primary investigators on the five-year, $8.6 million grant.
Scientists at the six clinical sites will follow 10,000 participants while they eat their usual diets. The study will also gather data on 1,500 participants who will follow one of three prescription diets while living at home. A final group of 500 participants will follow the same diets during stays at clinical sites.
Researchers will measure blood sugar levels and biomarkers of cardiometabolic health, such as insulin resistance, blood pressure and blood lipids. Wearables will be used to track participants’ physical activity and sleep. Researchers will also collect samples of blood, urine, saliva, hair and stool to assess the impact of people’s diets.
“Nutrition for Precision Health brings us a step closer to precision medicine. The study will generate a massive dataset, a wealth of biospecimens and the algorithms that will lead to personalized dietary prescriptions that can promote health, prevent heart attacks or strokes, and importantly, address health disparities,” said Pennington Biomedical Executive Director John Kirwan, Ph.D.
NIH awarded $170 million over five years, pending the availability of funds, to fund the Nutrition for Precision Health program. The program includes six clinical centers, a metabolomics and clinical assays center, a microbiome and metagenomics center, a multimodal data modeling and bioinformatics center, a research coordinating center, and additional support to existing All of Us infrastructure.

About LSU’s Pennington Biomedical Research Center
The Pennington Biomedical Research Center is at the forefront of medical discovery as it relates to understanding the triggers of obesity, diabetes, cardiovascular disease, cancer and dementia. The Center architected the “Obecity, USA” awareness and advocacy campaign to help solve the obesity epidemic by 2040. The Center conducts basic, clinical, and population research, and is affiliated with Louisiana State University.
The research enterprise at Pennington Biomedical includes over 480 employees within a network of 40 clinics and research laboratories, and 13 highly specialized core service facilities. Its scientists and physician/scientists are supported by research trainees, lab technicians, nurses, dietitians, and other support personnel. Pennington Biomedical is located in state-of-the-art research facilities on a 222-acre campus in Baton Rouge, Louisiana.
