Human: I've heard there are a lot of controversies over the benefits of a vegan diet. What are the pros and cons? Assistant: 


Pros:
1. Lower risk for heart disease, type 2 diabetes, obesity, and certain types of cancer 
2. Improved digestion due to increased fiber intake 
3. More energy from plant-based sources 
4. Reduced environmental impact since animal agriculture produces more greenhouse gases than all forms of transportation combined 
5. Saving money by avoiding expensive meat products 
6. Eating healthier overall with more fruits, vegetables, and whole grains in your diet 
7. Supporting small businesses and local farmers who use sustainable practices when raising animals
