Most of our turnrounds are long enough for a quick meal break, it's when we are running late that the pressure starts. Easy for us as we can eat in the flightdeck during the flight but much more difficult for the CC. My view is that humans have to eat and it's a flight safety issue, if it's time to eat anyone who wants to can and the departure can wait 10 minutes. Never had a problem from the management despite several keen dispatchers putting the delay down to "crew eating a meal".
