Hey there!
One thing I've noticed about the topic of food is that I think dietary phases in life are associated with equanimity -- if we're talking about the Insight framework and the stage of equanimity.
Even if we're not talking about Insight maps, any person who's moving away from some problems in their lives and moving towards being happier and healthier in themselves usually starts showing dietary changes...more regulation, more deliberate choosing/control over impulses because they naturally are ready to support their healthiness and the natural happiness arising from basic physical healthiness.
So meditation or not, I think people start to reduce sugars/carbs or even go ketogenic for awhile when they are eager to solidify a nice change in life (in mood, in body, in mind, relations, etc). Sugars tend to cause swift physical and mental changes and if they aren't used up in exercise the brain tends to feel their usage in mood swinging. So everyone seems to understand really quickly for themselves, "Time to eat better."
That said-- I also think post-equanimity presents with zero dietary changes and a lot of natural winsomeness/pleasantness-- in this "stage" people just go through periods where they are very satisfied with their work, life, etc and there's no need to take up dietary restraints or particular fitness even. I think that kind of mind is having a good effect on the body, just like when one meditates for some longer period and can arise easily: there's some bodily effect the engaged mind is having. Same as a person sitting happily at their desk all day if they love their work that day...
So, to your point (in my roundabout way):
I want to know what foods you all recommend and which foods you do not.
Consider paying attention to the surge of pleasure the mind gets from sugars, the grumpiness the mind often presents when not getting sugars, and then taking up a diet low in sugars and/or followed quickly by exercise.
