Oh my that looks good, and I really like the idea of my car smelling like home baked bread. Ohhhhh.

I'd not read that about Roundup but it makes a certain sort of sense to me. I grew up on a wheat farm and I didn't know a single person that was sensitive to gluten until the last 15 years or so.

That said, it is a not uncommon practice, but not all farmers use Roundup pre harvest. They use it when they have a weed infestation that will prevent them from harvesting. Roundup is not cheap and most wheat farmers live on a razor thing profit margin so don't do things that they don't have to do.

I will say that there would be enough of the practice to allow for a general sensitivity in all flour. Interesting stuff.
