A vegan diet excludes all animal products, including meat, dairy, eggs, and honey. It focuses entirely on plant-based foods, such as fruits, vegetables, whole grains, legumes, nuts, and seeds, providing a diverse range of nutrients, fiber, and antioxidants. This diet is often adopted for health reasons, as it can lower the risk of chronic diseases, as well as for ethical and environmental considerations, promoting animal welfare and reducing ecological impact. With careful planning, a vegan diet can meet all nutritional needs and support a healthy lifestyle.
