The unhealthiest fast food – you should stay away from this dish. If you're tossing between the Turkey Sandwich at McDonalds and the Big Mac at Subway, you'll do better with the sandwich at Subway.

A large burger from McDonalds, Burger King and Co. can quickly add up to more than 1000 kilocalories. For most people, this is more than half of their daily needs. But anyone who gets a box of 20 chicken nuggets should also be warned. This portion size is in no way inferior to burgers in terms of calories.
