We've been selectively breeding wheat so it's not the same wheat as it was back then. Our wheat is actually higher in gluten than it was 100 years ago. We know this because we keep samples laying around like that. People with actual Celiac Disease would still have a bad reaction, but many others are actually having a bad reaction to the saccharides. The acronym is FODMAPs, Fermentable Oligo- Mono- and Di- Saccharides and Polyols. And all those people could be cured by Christ.
But all this information is just pearls before swine. You don't care about actual medical research. I could post PubMed links all day and you'd still be posting trash like this for upvotes.
