Seriously.. I'd suggest to take something with you...
With the best will in the world the information on the actual ingredients for the "Standard" meals might get garbled or misinterpreted.. or there may simply not BE enough detail to allow a reasonable decision... It's not that I wouldn't "trust" the airline to help as far as possible.. but the people you speak to will (almost certainly) NOT be knowledgeable about such matters....
Not worth getting sick.....
