in short, yes, however using the GI scale isn't concrete in determining what you should and shouln't eat as a hypoglycemic. For example long grain white rice is low-GI but a definate no no.

You would be best off googleing a hypoglycemia diet for common suggestions to what you can eat. Unfortunately there are a huge amount of 'maybe' foods and this will be dependant on your own experience.

The is a good place to start

Konnor has some good points.

To repeat, low GI together with general hypoglycemia guidelines, are just that, guidelines. Start with that, then tweak it to suit you. Everyone is different - you may find that you can tolerate fruit where some people can't, or maybe you can't tolerate carrots where the next person can.

And don't forget to ask your doctor. With a diagnoses your doctor should have given you a general idea of the right diet to follow. If it was a bit vague (unfortunately it is sometimes!) then ask to see a nutritionist.
