Plant-based food refers to any food that comes primarily from plants. This includes fruits, vegetables, grains, nuts, seeds, and legumes. While it can also include processed foods made from these ingredients, the focus is on whole, minimally processed items. Plant-based diets are often associated with health benefits, such as lower risks of heart disease and obesity. Many people choose plant-based foods for various reasons, including health, environmental concerns, and animal welfare. A plant-based diet can provide all the necessary nutrients when well-planned, making it a viable option for individuals of all ages. Popular plant-based diets include veganism and vegetarianism.
