hmm here's one thing to think about
those foods are very low in sugar, so even though they may have a high G.I. (glycemic index) (if they even do, I don't know) they'd probably have a pretty low G.L. (glycemic load).
The glycemic load takes into account the quantity of carb in a food. So while carrots have an even higher glycemic index than jelly beans (!), they have a much lower glycemic load because there just isn't as much sugar in a serving of carrots as there is in a serving of jelly beans.
make sure you eat any carbs with protein and some healthy fats to slow digestion further and the low natural sugar content in those foods should not be a problem for you unless you are doing a diet which requires you to be in ketosis
