Beans are great, but require time to cook that not everyone has, especially when very poor. They also cost money to cook, require a kitchen, time to clean dishes, a place to store em if cooked in bulk, etc.
Bananas though, are wonderful, sent from heaven.
To some of your other posts, it’s not really sufficient that this food merely exists. otherwise, yeah, problemo solved, trivial.
The bridge that has to be gapped is: - foods gotta be accessible - people gotta have enough time to cook the food, this is a biggy - people gotta have time to clean up from the food - people gotta have enough of the healthy food and with enough macronutrient diversity to not get sick. $1 worth of bananas ain’t gonna hold you like that $1 cheeseburger.
Somewhere in all of this is that eating healthy is way more cognitive overload when you’re poor than when you’re stable. Now that I’m stable I have enough time on a Sunday to cook a weeks worth of meals. I don’t really have to scrunch to do it, I’m not cutting into sleep time to do it. Lotta folks don’t have that luxury.
