As someone that has been battling with ulcer for about a year or so now, I find this very insightful and also a call to order. I looked at all the ways you said ulcer can be annihilated and I'm guilty of so many of them. I love spicy and sugary foods to a fault and many times I forget to eat. I'm more or less a workaholic and don't know when to stop.
But I do love and eat bananas and avocados a lot so I guess that's a good thing.
