@zeak4hands - Palm sago isn't just to eat. It's in a lot of other things and I have no idea how people figured it out!
Sago is used in making biodegradable plastic, some types of glue, treating cloth fibers and making paper.
I think the worst use for it is in making high-fructose corn syrup and maltodextrin. I don't like eating either in my food -- one makes you gain weight and the other gives you diarrhea.
I was a little bummed when I found out that sago is in short supply and that local farmers are having trouble with their crops because companies are selling it abroad instead.
