It is no secret that food manufacturers try and make themselves appear better than they actually are, everyone knows that. But how far do they actually take it? All food adverts you see on television or on the street will be altered in a way which makes the meal inedible.
For example, did you know they use shaving foam instead of whipped cream in adverts because it doesn't melt as fast? Did you know that they put washing up liquid in beer to create the perfect froth? All these things are what goes on behind the scenes to make the food look more appealing. It's not like they serve it to you like this but it does cheat you for when you finally get a burger that is not as shiny or as big as you were promised.
