Well, processed food is. I'd agree that fresh produce in most areas isn't going to have an ideal level of vitamins and minerals. But I don't think it's a severe enough difference to really worry about too much.  That said, the difference between nutrient content in home made versus frozen/canned meals really is nuts. Vegetable soup is easily the biggest shock to me. It's almost impressive how companies have been able to make vegetable soup as nutritionally void as most brands end up as.
