<human>:  What are the health benefits of changing my diet to vegetarianism?
<bot>: Vegetarian diets tend to be lower in saturated fats and cholesterol than non-vegetarian diets, which can help lower your risk of heart disease and stroke.2 Eating more plant-based foods may also help lower your risk of developing type 2 diabetes, since plant-based diets are higher in fiber and can help reduce waist circumference, which is a risk factor for developing diabetes.3 High intake of plant-based foods such as fruits, vegetables, legumes, and whole grains can reduce your risk of cancer, as well as help maintain a healthy weight and keep your bones strong.4 Eating less animal-based foods can also help reduce your exposure to environmental contaminants, thanks to fewer animal-based foods that may have high levels of contaminants such as mercury or pesticides.5 Lastly, following a vegetarian diet may help boost your mood and energy levels due to the fact that vegetarian diets are typically high in vitamin B12 and other nutrients that can help regulate your mental and physical health.
