The field of nutrition has become one of the most confusing areas in medicine, with rapidly evolving science, conflicting headlines, and increasing public misinformation. The HLMS Nutrition Working Group brings together internationally recognized experts in nutrition, metabolism, aging, and lifestyle medicine to evaluate the evidence, identify areas of consensus and uncertainty, and translate that science into practical, personalized guidance for healthy longevity.
This multidisciplinary consensus paper explores the foundational principles of nutrition for healthy aging and how those principles can be thoughtfully personalized according to clinical context, life stage, metabolic health, functional goals, individual risk, and personal preferences. By combining scientific rigor with multidisciplinary expertise and clinical relevance, the Working Group aims to help clinicians, researchers, policymakers, journalists, and the public distinguish well-supported nutrition principles from premature claims, while translating complex science into practical guidance that can improve both healthspan and quality of life.
