Hi Icarus, I am known for flying by the seat of my pants when it comes to low blood glucose, mainly when it gets to 4 or 5 pm and I previously used to have a snack. It can be quite frightening seeing your results go down and down but this is what the diet is meant to do. Do not even think of brown bread, it is bread by another colour. Most things that say wholemeal, wholewheat, natural etc are not, they are manufactured. I know a little brown rice is allowed on this but only a very small amount. He is right, he does need slow release carbs (not a lot) and these are found in chickpeas, lentils, nuts, fruit (not too sweet), lots of foods if you can find a GI diet list on line.
Is your husband on insulin. As my readings came down I slowly slowly reduced my insulin. Like Bill says, Gliclazide can cause lows and I have cut mine from 3 a day to 2 but you might want to ask your doctor first. If mine get really low I have something like prunes or sultanas and a tablespoon of yogurt – advised to me on here as I didn’t want to go the bread, jam, juice root. Try to get him to have a mid afternoon snack left over from his lunch or make up a hummus dip with some celery or carrot sticks or eat an apple, all this before his bloods get too low. Is he checking regularly, I mean a couple of times a day. If he starts to feel shaky or any of the symptoms he should do a blood test, if it is low, have something good to eat. I know some of the foods don’t sound great but who knew I would come to love minted pea hummus served with carrot, cucumber and celery sticks.
Good luck
