A plant-based diet is a diet consisting mostly or entirely of foods derived from plants, including vegetables, grains, nuts, seeds, legumes and fruits, and with few or no animal products. A plant-based diet is not necessarily vegetarian.
The use of the phrase plant-based has changed over time, and examples can be found of the phrase "plant-based diet" being used to refer to vegan diets, which contain no food from animal sources, to vegetarian diets which may include dairy or eggs but no meat, and to diets with varying amounts of animal-based foods, such as semi-vegetarian diets which contain small amounts of meat.
The Academy of Nutrition and Dietetics issued a position statement proposing that well-planned plant diets support health and are appropriate throughout life, including pregnancy, lactation, childhood, adulthood, and for athletes.
