Hi katycrunch,
I sympathise because you're right at the foot of the old learning curve when you start out at diagnosis!
One of the first hurdles is starchy carbohydrates - or the rice and bread in the case of your husband's lunch. We've all been conditioned to think of them as staples of our diet - the stuff that fills you up and around which you base your meals. That's a biggie when you have diabetes, because those are the foods which your body turns into sugar very quickly. If you want to have non-diabetic blood sugar, and yes, you do, those are the things you need to replace. Rice and bread will do nothing for you besides raise your blood sugar.
There are lots of alternatives to try however. Have a look around at some of the other threads. If you replace the empty starches with foods which need very little insulin, your husband's blood sugar levels wil improve immediately. These foods include most vegetables, salad leaves, eggs, cheeses, meats, fish, nuts and so on. Believe me, you can eat really well, hunger will be a rarity and you'll wonder why nobody told you sooner!
All the best,
fergus
