what is jau grain - #25269

I am trying to understand this whole thing with jau grain. So, my granma started raving about it after her last visit to the village. She says jau grain is like, super healthy and stuff, but I’m not really sure what it is? She mentioned that people there use jau grain in all sorts of dishes, and it helps with digestion or something. But then I read somewhere online that jau grain also has benefits for boosting energy. I’ve been feeling kinda sluggish lately, you know? Work is stressful and I don’t eat as well as I should. If jau grain is as good as she says, maybe I should give it a try? Like, what is jau grain exactly? Is there a difference between jau grain and other grains? And how do I cook with it? Do you need special recipes or can I just add it to my regular meals? Any tips would be great! Can it really help with energy or digestion like she claims? Thanks, everyone!
