A plant-based diet primarily focuses on foods derived from plants, including fruits, vegetables, grains, nuts, and seeds. While it emphasizes whole, minimally processed foods, it can also include some animal products in smaller amounts. This type of diet is often chosen for health benefits, environmental concerns, or ethical reasons related to animal welfare. Many people adopt a plant-based diet to improve their overall health, as it is associated with lower risks of chronic diseases like heart disease and diabetes. Additionally, it can contribute to a more sustainable food system by reducing reliance on animal agriculture, which has a significant environmental impact.
