I like to click on the ads here to support the site. So I checked out one advertising info about the "Glycemic Index" and further clicked through to the list they've published of the glycemic indexes of foods. The page is headed with a carb-porn picture of a huge loaf of bread.
That made me think it might be a good idea to direct your attention to this blog post I published a couple weeks ago Why The Glycemic Index Fails for Many People with Diabetes
Do check this out. It's really disturbing how many people with Diabetes are told to eat foods their bodies can't handle because they are better for people who DON'T have diabetes.
