Has anyone actually eaten unhulled barley (hull still intact)?

This website claims that you can eat barley, hull and all if you soak it for 24 hours and then cook it thoroughly. Has anyone done this? Does it even work? What are the benefits if it does?

It stands to reason that if it’s possible, it should be healthier in theory. I would expect it to have a lot more antioxidants for example since it’s exposed to the sun, but I can’t really find anything on this topic. Even if it’s just 100% fiber and no other nutrition it would still be beneficial I’d imagine. Any input would be appreciated, thanks.
