A legacy of over 50 years in plant-based nutrition research
The Loma Linda University School of Public Health has a rich history of plant-based nutrition research. We engage in interdisciplinary research across public health disciplines and the Basic Sciences. This collaborative way of working is how we continue to promote and build on our core legacy of vegetarian and plant-based nutrition. Some key studies include:
- Nutritional epidemiology studies relating plant based diet patterns to health outcomes and longevity (the Adventist health Study)
- Several clinical trials with plant foods (nuts and soy) intervention and health outcomes
- Vegetarian nutrition education research
- Environmental impact of plant based diets compared to animal inclusive diets.
Areas of curricular strength and research emphasis include:
- Plant-based diets and the health of the individual
- Populations and the plane
- Nutritional epidemiology
- Diet and chronic disease risk reduction
- Community nutrition
Leading the conversation on plant-based nutrition
Guided by its Nutrition faculty, the School of Public Health hosts the International Congress on Vegetarian Nutrition (ICVN), the premiere scientific conference on the health effects of plant-based diets held every 5 years. The conference is designed to provide a review of the accumulated findings, and introduce theoretical concepts, practical applications, and implications of vegetarian dietary practices for both the prevention of disease and the promotion of health, as well as for the furthering of research endeavors. The theme for the 7th ICVN was Plant-foods for the health of people, populations and the planet.
The 7th International Congress on Vegetarian Nutrition
In February 2018, we hosted the 7th International Congress on Vegetarian Nutrition, on the campus of Loma Linda University. Since 1987, the congress has been held only every 5 years and is the premier scientific conference on the health effects of plant-based diets. It brings together international scientists, physicians, nutritionists, dietitians, and other health professionals to showcase the latest advances from basic science, epidemiology, and clinical trials in vegetarian nutrition. Proceedings for the 7th ICVN are underway.
