The obese kids eat too much supermarket and hawker foods, and even home-cooked foods, then the adults blame the ocassional fast foods because they read junk food news on newspapers written by someone totally unknown and unqualified and unquestioned. Bread is bread. It's same calorie and nutrition whether bought from Mc or supermart. It's all made from the same wheat flour. Just like meat is meat and Coke is Coke. Coke from supermart shelf can't be of less calorie and more nutrition than from Mc tap, only cheaper.
Kids in the US are not only obese but having problems with diabetes.
Same thing in Spore because parents are too busy at work to bother with home cooking. Haven't you ever wondered why there are now fatter kid around

If you look pass the bread, MacD uses alot of transfat oil to FRY their fries, same thing with those burgers which are also fried. The oils they use are the bad transfat kind & have been re-used a couple of times. Well known that frying is the worst way to cook foods.
Places like MacD do not include any veggies, the lettuce they include are just for show lah.
Drinking coke, pepsi,..., with every meal is unhealthy

Places like MacD & KFC are pushing coke/pepsi. A can of that contains 8 teaspoon of sugar. So you can imagine the amount of sugar you're getting.
Don't forget about the sauces they include with the burgers to give it taste. There's alot of salt & sugar. If you google, a big mac contains 1040mg of salt. The US RDA recommendation is 2,400mg from ALL sources.
The description of "junk food" is well deserved.
