The title may intrigue or amuse, but I'm serious. My wife, a Thai woman from Isan, very often complains of constipation and occasionally of hemorrhoids. Now, everyone in the world has come across those problems before, I'm sure, but what I notice is that besides my wife, it's nearly everyone in her family who complains of them. I have come to suspect it's their food that does that to them. My wife appreciates the western food I sometimes make (I'm a decent cook), but only nibbles up a bit of it and goes back to food she makes herself, Thai-Isan food of course, even when we are outside Thailand. Myself, I have nearly never had these problems.
What do the "experts" think of it, and what would they advise?
