i think a big part of it is people simply don't value good food and don't see it as impacting health. Crazy as it sounds, i've had otherwise intelligent people tell me they don't think the food they eat has any impact on their health. That was a big eye opener for me, in terms of what other people think.

When cookies were removed from schools, some parents even protested (literally protested, as in with signs and petitioning outside of the school marching back and forth -> i saw it on the news) for the cookies to be put back in !!!! My jaw nearly dropped to the floor and rolled out the door. It's just clear, that there's a lot of really really misinformed people in the world.

Also, not all healthy food is expensive. Organic Beans are super low cost and make an excellent staple. Personally, I also love oat meal. both are super high in nutrients, fiber and protein and very low cost.
