<human>:  Can you help me research the benefits of a plant-based diet?
<bot>: Of course - a plant-based diet has numerous physical and mental health benefits. Eating more fruits, vegetables, whole grains, legumes and nuts can improve heart health, lower cholesterol and reduce the risk of stroke, as well as helping to maintain a healthy weight. Studies have also linked plant-based diets to improved mental health, better brain function, and even a decrease in the risk of some cancers.
