I've listed this in the Eating section, but I will list this here as well.
Here are a couple of links listed in the most recent newsletter I received from ADA (American Diabetes Association).

The first one, you can either use online, or download to your PC.
If you are wondering what nutrients exactly are in whatever you are eatiing, this may be a good place to get the info, and keep your eating on track. I hope you'll find it useful.
