<human>: I've heard that a vegan diet is very healthy. Is it?
<bot>: Yes, a vegan diet can be very healthy and nutritionally adequate. A vegan diet typically includes plenty of fruits, vegetables, legumes, grains, nuts, seeds, and other plant-based foods, which are all high in essential vitamins and minerals. Plant-based diets tend to be higher in fiber, antioxidants, and phytochemicals than non-vegan diets, making them more beneficial for overall health.
