Vegan And Type II

I got this interesting article about the Vegan diet and diabetes. I have type II Diabetes, though I do not have to take medication yet, I still have it. I have to be mindful of what I eat, sometimes my emotions get the best of me. I do not think I could go Vegan, because I love cheese and yogurt. I still found it interesting. I am aware that I need to improve my diet in a lot of ways. Why is it the cheap food is so much cheaper than the food that is good for you?
