Seriously, you have Type II Diabetes, hardly a rare condition. My husband has the same as do many other travelers.
If you are going the low carb route the answer is to simply use common sense. Would sardines in a tin be appropriate...probably not. Easily solved placing them in a small plastic container...or even more easily solved by NOT CHOOSING SARDINES FOR YOUR FLIGHT. There are
