The Stanford Plant-Based Diet Initiative (PBDI), made possible by a generous gift from Beyond Meat, and led by prominent nutrition scientist Dr. Christopher Gardner, is dedicated to researching the health and environmental benefits of plant-based diets.
PBDI provides seed grants to scientists, hosts symposia to share research, and creates resources to make findings accessible to all.
This initiative focuses on identifying optimal plant-based alternatives to animal products, promoting human health, and improving environmental sustainability. The goal is to foster a healthier future for both people and the planet.
Our Definition of a Plant-Based Diet
A way of eating that emphasizes eating mainly plant-based foods. Meat and dairy products may be occasionally present in meals and snacks, but take a supplementary role, rather than star. A plant-based eating pattern focuses on whole foods including fruits, vegetables, whole grains, beans, legumes, soy, nuts and seeds, plant oils, herbs, and spices, rather than a high proportion of processed or ultra-processed foods high in added sugars, fats, and animal products, that are common in a traditional Western diet.
Environmental Impact of Plant-Based Diets
The typical U.S. diet, high in beef and dairy, contributes significantly to environmental harm, from methane emissions to inefficient land use for animal feed. Plant-based foods, however, have a carbon footprint 7.5 times lower than beef. Shifting to a more plant-based diet would not only reduce greenhouse gas emissions but also free up farmland for more sustainable crops, offering benefits for both human health and the environment.
Health Impact of Plant-Based Diets
Research shows that plant-based diets, such as Mediterranean and vegetarian diets, are linked to lower rates of type II diabetes, cancer, and heart disease.
Shifting to a plant-based diet is not all or nothing. While a vegan diet eliminates animal products entirely, many intermediate approaches—such as reducing meat intake—can also promote optimal health and are more realistic for widespread adoption. The popularity of plant-based alternatives like Beyond Meat offers an opportunity to reshape public perceptions and behaviors around plant-based eating, driving long-term change.
Plant-Based Diet Initiative Seed Grants
PBDI champions the positive impact of plant-based diets on individuals and the environment. Our PBDI biannual seed grant program, open to all Stanford faculty, fellows, and students, funds innovative one-year projects exploring various plant-based nutrition topics.
