Hi Janice:
If a diabetic DOES NOT have a snack on schedule, it is easy to go into shock (too much insulin not enough sugar). A suggestion to carry a sugary snack at ALL TIMES (ie a candy, juice, sugary drink are suggestions.) I do have a candy in my purse/pocket ALMOST all the time.
An aside, my Dad was bad - he use to faint from sugar lows - fortunately it was in his garden, not while driving!!)
re diet control - mainly follow the diabetes diet, no sugar, minimal salt, no prepared foods (it has hidden sugar/sodium/and unpronounceable chemical ingredients). (an aside, I think more people should follow this diet along with daily exercise of 1+ hours.)
re: old fashion control before insulin injection (
Diabetes: The discovery of insulin (medicalnewstoday.com) I heard that it was diet only to control diabetes. A difficult situation as ingredients in the past WERE NOT listed on prepared foods. I think the life expectancy of diabetics were a few years after diagnosed (not 60 years in my case!) as there were many side effects of uncontrolled high sugar (ie: kidney, liver, brain, eyes, hand, feet). Often damaged extremeties (feet) are amputated due to poor circulation)
I am Chinese, lots of vegetable stirfrys with fresh seasonal vegetables and minimal meat (mostly chicken),
An aside, my breakfast for 364 days/year is Bircher oatmeal (aka uncooked large flake oatmeal) with kefir, blueberries, and a tbsp of chopped walnut or almonds. 7 bowls are assembled on Sunday and breakfast is ready after the 1 mile walk. (I am lactose intolerant and able to digest kefir, not milk)
