Are you eating the tofu because you particularly like it, or are vegetarian?
Or are you keeping away from meat and seafood because you think it is bad for your diabetes?
There is a lot of talk about what level of protein is the healthiest these days, but the only reason that is most important for you as a diabetic is how readily excess protein is turned into blood glucose in you. For me personally - it must be an awful lot - and I may never have exceeded it. As I experimented with eating a lot more dead animal and fish products one month, and I had the best triglycerides reading ever that month (ie any excess protein and fat being circulated as fatty acids in the blood.) (Fatty acids in the blood contribute to insulin resistance, is my understanding.)
This won't help you with your chinese restaurant experience today, but it will in the future - it is pretty straight forward to check how protein affects you personally is to experiment with eating, and getting a blood lipids test done - before and after you have changed your way of eating, to see how your blood lipids are affected. (Therefore heart health - the next important thing for we diabetics to watch, after our blood glucose levels - which is every organ health!)
But I say all this as a very happy ethical I hope - carnivore. I love to eat meat and seafood. Those things are happy healthy additions to my diet. They don't affect my BG levels, but in a positive way by making me healthy and full, which reduces my cravings for the dangerous carbohydrates. When I go to Asian restaurants I eat meat and or seafood with veges - no rice of course! No noodles. (Of course!) Easy to do. Try and go to a restaurant which is a non MSG user, would be the next most important thing (in my humble opinion at any rate.)
Bon appetite!
