Not all food is processed....the produce department is made up of fresh food, nothing is added to it to keep it fresh or color is not infused to enhance their colors. Fresh meat is basically not processed save for the butchering of the cuts in a factory type setting, they have talked in the past of the use of coloring to enhance the redness of meat. Actually as far as I know meat can turn brown when it contacts air....so brown meat may look "off" but really it generally isn't. I think processed foods are found in boxed items, and frozen items......Processing is supposed to make food last longer, so they infuse the stuff with all those crazy sounding words you can't pronounce......never go that idea as I buy things to eat, not save up......
My general deal is buy fresh, cook fresh, bathe daily (to stay fresh) and keep your hands to yourself (or you'll be called fresh).....
