@dorisena I'm sure there may be a list of some items somewhere, but I've never seen one. Here is an example of how to get the Net Carbs. I pulled a can of mixed greens out of my pantry.
First, I look at the Nutrition Label. Calories per serving = 20. That's good. Second, look down the list. It says Total Carbohydrates = 4g. Third, under that is Dietary Fiber = 2g and then total sugars = 1g. To get Net Carbs. Start with Total of 4 and subtract fiber 2 and sugars 1. 4-3=1. So Net Carbs are 1g. That's why dark green vegetables are excellent diabetic food choices.
If a label does not include all of that, I research on the web. I use index cards and have this info for each food I eat with this info on it. Then I just add Net Carbs to see how many each meal has.
I hope this helps.
