nutrition and health

Question
i know some foods are not very nutritious, like eating a qauterpounder from macdonald's would not be as nutritious as eating a healthy option chicken salad, but why?, is it cheaper to make things less nutritious?

Answer
Interesting question Jamie! Humans are the result of thousands and thousands of years of survival of the fittest (as in any animal species).  Before there was widespread agricultural (farming) practices, we had to hunt and gather our daily food intake.  Mostly eating the meats of animals we could catch, to balance our nutritional needs with fruits, nuts and vegetables, a certain 'taste' for it had to be hardwired into our brains.  Fruits were our first taste of sugars.
To make a long, long story a bit shorter, the fast foods of today play on our instincts of thousands of years ago. They are high in those things we are biologically programmed to crave - fats, sugars and salts - which helped insure our survival at one time because they weren't so common.  These days, we just overdo it to a ridiculous point.

Ideally, we shouldn't give these things up, but we should limit them.  A typical fast food or restaurant meal in the U.S. is on the average, THREE times the size it should be (this includes drinks!). So, it's not likely anyone will cut that burger into 3 pieces and only eat one, but cut in half is not unreasonable - and make TWO meals out of it.  

It's something that CAN be learned.  Just like overeating is learned.  

Finally, considering the actual size of those burgers (about the thickness of a carboard box flap), the vats of fat used to process/cook it and yes, the inexpensive cost of bread products for this industry - it's a LOT cheaper to sell a burger that cost THEM maybe 25-50 cents to make, to the public for ?????  Even though the chicken salad is ALSO cheap ingredients (the lettuce is of the least nutritional value of all the lettuce's they could possibly use), it costs more to process it (cutting, washing) and has a shorter storeage or shelf life (those patties can be frozen for months and months...but not lettuce!).  
With the profit margin even a few cents lower than what they're used to - it apparently justifies the huge increase in price.
Sigh....it's all about the Benjamins.  Sad.
