Some people are definitely sensitive to gluten, but even the guy who brought this to the public's attention says that too much has been made of it. I was keto for a time, and have been in the past, but I always reach a point where meat becomes unpalatable to me. So I go back to a balanced diet, with my grains (mostly) whole.
I bake my own WW bread, and even add gluten to help it rise, as WW is naturally weak in that area. I used to buy organic flour, but that became inconvenient. But I still insist on non-GMO. Take a look at a picture of dwarf wheat, which is an invention, it looks like an indestructible industrial product. It has twice the chromosomes as heritage wheat, and the story is that our bodies have a hard time digesting it properly. So non-GMO is important to me.
As for oils, check out Mercola's
interview with Tucker Goodrich. He reminds me of Buhner, being self-taught and having no degrees, but being brilliant. The omega-6 oils are not good for us and should be minimized. I've just gotten serious about
this of late, and have all but eliminated peanuts, a biggie for me.Their o6 to o3 ratio is 5000 to 1! If you really want a scare find a video of how Canola oil is made. It is a repurposed industrial product, as is cottonseed oil (Crisco), and many of the others.
Here is a good introduction.
