Ronnie, too bad about your husband's diagnosis. I hope he adjusts well to his new lifestyle.

I have no personal experience with this disease, but I usually eat a low-carb diet that is pretty familiar to a mild type 2 diabetic. No sugar, avoidance of refined carbohydrates, lots of vegetables, lean protein, whole grains etc. I have had no problem on three Radisson cruises adhering to this pretty well (aside from the desserts that I got roped into eating against my will.)

Diet soft drinks, for instance, have not been a problem. I have not been on Mariner, but they seem to always have a simpler dinner menu for those who can't eat rich food, and I'm betting that he will be able to do pretty well. I would say the biggest challenge sometimes is finding the right kinds of whole grains on a cruise ship.

All that being said, I don't know what the real dietary pitfalls are for diabetics--sugary salad dressings, sauces(?). But you should certainly contact Radisson and ask them about how they will accommodate him.
