Blue smoothie

I want to improve my health given that my cholesterol is high (255) and I have type diabetes. I've stepped up my exercise (pun intended) and made some adjustments in my diet. No cheese or meats for me for a while. Today, my wife made me a smoothie dinner consisting of some spinach, a lot of blueberries, walnuts, and a banana.

It's pretty good and I think I could have one every morning. It's low glycemic and chock full of vitamins and minerals. Blueberries contain pterostilbene, a compound that is known to lower blood glucose, lipids and cholesterol. At least in laboratory animals.
