I firmly agree with you, Zeb, USE SOME COMMON SENSE! lol!
Regular food is fine - it's even BETTER in most cases - but just not ALL regular food and not in unlimited portions. Plus there's a difference for the patient who takes insulin and is better able to control a spike after it happens, than the one who's on oral meds, or perhaps just diet/exercise, and if that one experiences a steep spike, just has to wait it out or else exercise vigorously if possible, to bring levels back down.
I learned at the outset to avoid anything processed, and especially those ones that advertise as sugar-free, no-sugar-added, or diabetes-friendly. Another thing to watch out for is the low-FAT products. These are likely to be higher carb since the manufacturers remove the fat & replace it with other modified (and usually carby) substances.
My instructions at diagnosis were to keep carbs under 100g per day. Doc warned me that if I ate a big baked potato for supper, I'd see it on my meter in the morning. So I scratched on the baked potatoes, but continued to enjoy my homemade whole wheat & sourdough breads, pasta, brown rice. etc. But soon found that I could not attain a reading under 140 by any combination of foods/menus. So then I had to learn that even the regular foods like bread, rice, pasta, potatoes, etc., would need to be limited if not completely avoided if I were to attain my target glucose levels.
Once I trimmed my carb intake down between 50 & 65 grams per day, I began to get the meter readings I want to see - clustered round 100 and no higher than 130. And I've now found certain brands of pasta, breads, etc., that I can enjoy without exploding my meter!
I dearly LOVE Dreamfields pasta & can eat it with abandon. Certain brands of low-carb tortillas work much better with my glucose than the usual cheap flour ones. LaTiara makes a wonderfully thin crispy corn tortilla shell that's only 4g of carbs per shell. Nature's Own bakery has taken the step of removing HFCS from all their bread products! Yay!!! I can have a slice of buttered toast again!
So yes, regular foods really are the ticket - just choose wisely.
