No, a plant-based diet and a vegan diet are not the same. A vegan diet excludes all animal products such as meat, dairy, and eggs, as well as by-products from animals. Vegans also extend these principles to other aspects of their lifestyle, by avoiding materials like leather and animal-tested cosmetics. On the other hand, a plant-based diet focuses on consuming primarily fruits, vegetables, legumes, and grains. However, it may still include a limited intake of animal products. It mainly refers to dietary choices, not necessarily lifestyle. Hence, all vegans follow a plant-based diet, but not everyone on a plant-based diet is vegan.
