Hypoglycemia and diabetes aren't the same thing. :)
Hypoglycemic people should not do the MC, as the glyecemic index of the maple syrup is too high for them. They feel sick because their body is capable of making the insulin to transfer the sugars, but it makes too much so the blood glucose goes way down and they get racy heartbeat, weakness, and all the other symptoms.
People with or on the verge of diabetes have a weak pancreas, so are unable to make insulin to match the sugars. That means sugars are not being transported where they should be as often as they should be, leading to high blood glucose, not low. So the best answer for them is just a litte bit of Sugar very frequently.
gosh I hope I explained that clearly, high/low right/left can get my dyslexia going! LOL! :)
