What is a Vegan diet?

A vegan diet excludes all animal-derived foods, including meat, poultry, fish, dairy, eggs, and honey. It focuses on plant-based sources such as fruits, vegetables, grains, legumes, nuts, and seeds. Many people choose veganism for ethical, environmental, or health reasons. When well-planned, it provides sufficient protein, fiber, and antioxidants, though supplementation or fortified foods may be needed for nutrients like vitamin B12, iron, and omega-3 fatty acids. Vegan diets are associated with lower risks of heart disease and improved digestion but require mindfulness to ensure balanced and complete nutrition.
