Multiple things are wrong with nutrients by processing them.  For example vitamin C supplements are not as healthy as actual Vitamin C.  They cause your arteries to harden.  Processed food labels don't even properly reflect the proper nutritional value lost in processing.  You get less protein per gram of beef jerky then you do before it was ever processed.  Also the same logic for supplements not working, processed food passes through you faster.  This is totally endorsed by the food industry just like our bad nutritional guide lines were.  Nutrients loose building blocks in processing and they are not what you need.
