My daughter eats raw meat sometimes, or very rare. As a diabetic parent It's in the back of my mind. She is a very healthy eater, with healthy habits, and an open mind. I have been open about all of my crazy idea's and she has experimented to various degrees. When her tests came back off the charts for gluten sensitivity she was 8. Her Italian grandparents didn't agree that pasta, and bread where hurting her. Her GI doctor, agreed with them in spite of her test results. (Always have your family's lab results sent to your house and google any abnormal results). MD refused to test her for celiac, saying that she "looked to healthy to have celiac."
I was the bad guy, everybody in the family was upset, including my 6yr/o. I gave up, 4yrs later Ivy read a pamphlet about how celiac causes acne. She had bad acne and hated it. She asked me about that gluten thing and what I suggested. She was gf after that, her skin cleared dramatically, and she felt better. She refused to eat anything with gluten on her own, and family had to comply. For Father's Day they went to Chinese and she only ate steamed rice, but she became very sick, couldn't go to school due to severe head and stomach aches. Acne flared up too. Now she won't eat out unless she has a gf menu.
Point is. Children either have to be very young and have full support of all family members or old enough to decide for themselves. Otherwise, pick your battles. If its type 1 diabetes. I would seriously consider going very low carb, no grain, no added sugar (including honey), only fresh raw low starch vegetables, high quality meat, fish, and fat. If you cook meat a little so family and friends and child don't flip out, it's still a great start, and you can increase raw as the years go bye.
Type 2 same thing, but a few starchy veg. And fruit are ok, if only in moderate amounts. Get the child moving in the fresh air preferably, and get them to bed early. 8pm for both type1 and 2. You'll probably have to move a mountain to get that far ; ).
Let us know.
How are you doing with diabetes/general health/diet/wellbeing?
