Big corporations can make lots of money selling expensive salad dressings if I'm convinced to buy icky tasteless styrofoam iceberg lettuce. Therefore the intense push to get people to eat veg/fruit in the form of salad. "They" might not be selling profitable wheat flour in the form of twinkies anymore, but "they" are selling salad dressing for about the same cost per pound as chicken/beef (depending on dressing and meat cut, etc), gross fake bacon bits, etc.
I occasionally eat salads but eventually I get burned out on the salad dressings (there really aren't that many) and stop for awhile.
The most revolutionary thing you can do is just eat an apple or gnaw on a carrot or bake a potato. No dips or crusts or toppings or any other profit centers. Assuming you already have enough fiber in your diet, run your veg thru a juicer. That really pisses "them" off.
