Following a vegan diet, or even just including more plant-based foods in your routine, can be a healthy and delicious approach to eating. Research has shown that cutting back on animal products and eating more beans, whole grains, fruits, vegetables, nuts and seeds is associated with a decreased risk for diabetes, heart disease and certain types of cancer. Plus, you may have an easier time losing weight on a vegan diet, thanks to fiber-rich foods, which help you feel full and satisfied throughout the day.
