Decades of Research Behind the Longevity Diet and Therapeutic Nutrition
The Longevity Diet is rooted in decades of research on aging, disease prevention, and optimal nutrition in diverse populations. Its principles focus on plant-forward eating, moderate protein intake, and limiting refined foods—patterns shown to promote healthier aging and reduce risk of the most common chronic diseases.
Large cohort studies show that higher adherence to plant-based and longevity-associated diets correlates with substantial improvements in physical function, mental health, and survival to advanced ages compared to less healthy eating patterns.
Medically tailored meals—prepared and delivered according to therapeutic guidelines offer a practical way to “prescribe nutrition” for people living with diabetes, heart disease, kidney conditions, and other chronic illnesses, with research demonstrating major reductions in hospitalizations and costs.
Food is medicine programs are increasingly recognized by healthcare systems, payers, and policymakers for their role in managing illness, improving health outcomes, and supporting patient-centered care.
