No one needs gluten to stay alive, gluten is hard on our guts lining and causes inflammation. Most people are healthy enough to handle gluten but because of chemical laden society many peoples guts are leaky and gluten can migrate to other areas of the body causing an allergic reaction. I also have read we may not be allergic to gluten or the combination of gluten and glyphosate in weed killer is causing immune system and digestive problems. There are societies that do very well and never eat gluten. I also read modern wheat has been hybridized to produce more gluten than primitive forms of wheat. I wrote a bunch of vaccine articles and one of the main subjects that came up in scientific studies was damage to our digestive system. There are so many things in our modern life style that are harming our gut bacteria and our digestive system. The digestive system is like our second brain and a big part of our immune system.

I think I was just speaking from my personal experience since gluten is a main part of my personal diet. My diet is actually quite crappy since I eat a lot of baked products, cookies, sweets and such.
You are so lucky @hashcash...sigh
