sure. but most people are lazy and a quick fix processed snack is usually the choice made over thinking...."Oh, I am feeling a bit hungry/peckish.....so, I had better make myself something to eat".........

a)*munches on an apple/carrot whilst going to fridge/freezer/pantry making decision on what to cook/make.....20 mins to 1 hour + later consumes food

or

b) buys a donut/chocolate/packet of chips/hot chips/takeaway/biscuits etc etc etc
