I wonder, for those people that cannot tolerate beta blockers, should they also pay attention to natural beta blockers. Ten of these are: bananas, pomegranates, passion flower, chamomile tea, turkey, potatoes, oatmeal, broccoli, valerian root, and tuna. I think, for me, they can have a negative influence. Thinking back, these foods could have been the cause of AF issues. I will now pay more attention each time I eat these. May be I need to avoid or reduce the consumption of some of them.
