Why is healthy, organic, simple food more expensive than unhealthy, processed, chemical-filled food?

Surely it's a lot cheaper to grow a bunch of vegetables and make a salad than it is to go through all the logistics that are required for processed food? Shouldn't the cost of production be reflected in the price we pay for it?

edit, When I said organic, I didn't mean shit like 'organic' bread or whatever bs, I just meant things you pull out of the ground to eat.
