A plant-based diet involves consuming primarily foods that come from plants, such as fruits, vegetables, grains, nuts, and seeds, while minimizing or eliminating animal products like meat, dairy, and eggs. This dietary pattern has gained popularity in recent years due to its potential health benefits, including lower risk of chronic diseases like heart disease and certain types of cancer. Additionally, plant-based diets are often touted for their environmental sustainability and ethical considerations. Researchers in this field study the health effects of plant-based diets, optimal nutrient intake, and ways to promote adherence to this dietary pattern in the population.
