It's long been a question asked by holiday-makers: Why does airplane food taste so bad? However it seems, surprisingly, the chef is not to blame.

It's not actually the quality of the meals served that's at fault - it's passengers' taste buds, according to research.

'At 35,000 feet, the first thing that goes is your sense of taste,' explains Grant Mickels, the executive chef for culinary development of Lufthansa's LSG Sky Chef. Apparently the ingredients aren't to blame after all. Regardless of which meal you're eating - from fish, meat, and even pasta - it will taste 'so dull in the air' compared to on the ground.
