For those in the camp of "gluten is harmful to everybody and will kill us all"...

there is a massive experiment which has been running for over 100 years with tens of millions of people being administered massive daily doses of gluten (mostly from 100% refined white wheat in the form of pasta, bread and pizza) from birth to death.

The results show that these people live healthier and longer than average lives[1]. The experiment is called Italy :)
