lower sugar in prepared foods is better, but you really do need to watch the total carbohydrate fiure, especially for a T1 diabetic.
It's actually better to cook from scratch if at all possible and to keep to an absolute minimum on baked goods, breakfast cereals, rice, pasta and potatoes. Meat, fish, dairy, eggs and fresh green veggies work best with a little fresh fruit.
If your father is receiving a hospital "Diabetic diet", that will be part of the reason why his blood glucose isn't going down. Hospital diabetic diets are pretty high in starch, which as someone has already poseed turns 100% into blood glucose.
When I was first diagnosed in hospial following a stroke, I didn't know what i do now and my sugar, as measured by the nurses stayed pretty high. Iate what Iwas given thinking it MUST be alright.
Once I learned how to manage the diet, I got my blood glucose down into the non-diabetic range, and keep it there. It's a little different with insulin, but if you want to read up on it, get a copy of Dr. Bernstein's Diabetes Solution. Get it from the library. It's expensive, but also American, so you need to learn to convert the blood sugar units. Which is Easy. American ones come out 18 times bigger than ours.
