Rethinking healthy eating: Purdue Nutrition Science researchers explore the science behind ‘precision nutrition’

Nine Purdue University Department of Nutrition Science researchers and other colleagues collaborated on a report finding people respond very differently to the same foods, which is why “precision nutrition” — tailoring dietary advice to individuals — is gaining attention. In this review, the researchers studied how behaviors are shaped by a complex mix of biology and lived experience — including influences of age, sex, body size, genetics, culture, appetite, taste, smell, gut–brain signals and the microbiome.
