<human>:  Can you explain the difference between vegan and vegetarian diets?
<bot>: The main difference between vegan and vegetarian diets is the way they relate to animal products. Vegans avoid all animal products, including dairy, eggs, and honey. Vegetarians on the other hand, may consume some animal products, including dairy and eggs, but avoid meat and fish. Both diets are plant-based and typically involve avoiding processed and refined foods, focusing instead on whole, unprocessed foods like fruits, vegetables, legumes, nuts, and grains.
