I was hospitalized a week after eating many bags of sour gummy worms... very good but I did always suspect they might've played a role in how I was feeling.
I try to watch what I eat to help my gut bacteria... but that stuff is so impossible to understand. Pretty much everything hurts good gut bacteria, like hot coffee, grains, and other stuff I'm forgetting. It's just impossible to try and optimize your diet beyond simple macros tbh.
