A vegan diet excludes all animal products, including meat, dairy, eggs, and honey, focusing instead on plant-based foods. This diet emphasizes fruits, vegetables, whole grains, legumes, nuts, and seeds, promoting a wide variety of nutrients while often being lower in saturated fats and cholesterol. Vegans choose this lifestyle for various reasons, including health benefits, environmental concerns, and animal welfare. Proper planning is essential to ensure adequate intake of key nutrients such as protein, vitamin B12, iron, calcium, and omega-3 fatty acids, which may require supplementation or specific food choices to meet nutritional needs.
