A plant-based diet focuses primarily on foods derived from plants. This includes not only fruits and vegetables, but also nuts, seeds, oils, whole grains, legumes, and beans. While plant-based diets can vary widely in their composition, they generally emphasize whole, minimally processed foods. Here are the key aspects of a plant-based diet:
Types of Plant-Based Diets
- Vegan: Excludes all animal products, including meat, dairy, eggs, and often honey.
