A type of plant-based diet that excludes all animal products is known as a vegan diet. This dietary pattern focuses solely on plant-derived foods, meaning that it avoids meat, dairy, eggs, and any other animal-related items. Individuals choose a vegan lifestyle for various reasons, including ethical concerns, environmental consciousness, and health benefits. A well-planned vegan diet can provide all necessary nutrients, although it may require careful consideration of sources for protein, vitamin B12, iron, and omega-3 fatty acids to ensure balanced nutrition.
