Hi,
How lovely for your hubby to have such a supportive wife.
Please tell him he is saved from having to eat pasta. It is a no-no for diabetics as there are too many carbs in it. Heaven knows why our health care people tell us to eat starchy carbs. This information is wrong. All carbs turn into sugar once digested - and some as soon as they arrive in your mouth. As Fergus said above, he needs to avoid pasta, potatoes, rice, bread, pastry, batter, or at the very least seriously reduce the portions he eats. We are all different, and some can cope with small amounts of these bad carbs. Some can't. The only way to tell is by getting a blood glucose meter and self test before and 2 hours after a meal to see what happens to your levels. For example, I can cope with one slice of granary bread, but not two slices.
He can eat meat, fish, eggs, most but not all vegetables, some fruits (not tropical ones like bananas), butter, cream, yogurt, olive oil/rapeseed oil, salads, tomatoes, mushrooms, beans, lentils etc etc.
I can see that reducing his carb intake is going to be difficult if he needs to gain weight.
