Oh come, I know we would all defend a good employer (and they are that) but your oft repeated protests on McDonald's being "real food" are transparent shilling.
It's crap, sugary, syrupy sweet crap at that, and highly calorific junk food. Yes I know it's real beef, real coffee beans, real potatoes... (but it's a sad company who needs to assure people that its beef comes from cows and its chips come from potatoes). Tellingly It's also real sugar, from sugar cane, and real fat, from animals, and lots of it, in both cases.
A *medium* big mac meal is over half the calorie intake of what a human needs in a day, and people have that for lunch, not their main meal. Go large and you're at the threshold of that being all you're allowed, (unless you like wearing size 22 dresses as a matter of course).
Yes, you eat it occasionally and yes, it won't kill you occasionally, but the constant queue of people at every "I can't even be arsed to get out of my McCar" McDrive is testament to the fact that for many it's far from occasional. It's a long term habit.
Its terrible, sugary, highly calorific crap which is helping lazy Brits become ever more obese and lazy, and shame on you for defending it.
I'm not going to pursuade you different, but to come back on a few points.
I am not employed (nor ever have been) by McDonalds or similar.
Yes a McMeal is a meal and interestingly there are calorie constraints on their meals, you may not like where the bar is set, but that's the case.
The Nutritional values of all its products are available in-store and online.
A quarter pound of beefburger in bread for lunch is never going to be a great start wherever you buy it from. The beef is very good quality. I find it funny that people denigrate McD but are happy to by god knows what from greasy Joe's van around the corner - Or most take-aways with food of unknown provenance.
The Fries are just that, potatoes fried in vegetable oil, just like people may do at home. And from my experience far less oily than certain frozen fries that are oven baked. Nothing special there, fries are unhealthy whether from Harbour View chippy, McD or home.
If you buy a full fat coke, shake or Ice-cream no shoot-sherlock, they are full of sugar and fat, that's what these things are wherever you buy them from. Coke is a crappy fizzy drink that some people like, it's not my choice (I'd ban them) but hey it's not my world.
I am happy to defend the Mc products that I have experience of because from what I have seen they are made from consistent good quality materials from long-term sourcing partners, the traceability is second to none. The standards of hygiene, manufacture, quality control and food safety are world-class.
Is it perfect? No, but it's far, far better than given credit.
The rest of your post however is not about the Mcfood or its quality, but about people's dietary choices and that is primarily a very complex socio-economic issue that urgently needs to be tackled. To blame McD and it's ilk is a simple knee-jerk by those that do not have a grasp of the problem.
