I noticed significant improvement in my bowel health after stopping eating nuts. They were my go to healthy snack but I don't really eat tree nuts at all anymore. You're only supposed to have like 2 or 3 of them at time anyway, and that's pretty much impossible to satisfy a craving. Peanuts however have nothing to do with tree nuts. They are legumes. I still eat peanut butter and eat about a pound a week.
