A note for those flying BR: their J meals are high carb / high fat because (according to the SD) their primary customer in J is the Taiwanese businessman who wants this.
Mrs Haz is on a low carb / low fat diet and could eat hardly anything. They tried to do their very best with what they had on board, but it's not like you can pop out to Loblaws at 38,000 ft so she had slim pickings.
A special meal would have been the answer.
