What kind of symptoms do you have exactly?

Are you sharing your kitchen with gluten-eating people?? Are you using the same kitchen equipment as you used to prior to your Paleo/gluten-free diet? Could there still be tiny breadcrumbs in your drawers contaminating your food? Do you lick envelopes or stamps (the glue is wheat-based)! Have you had a look at all your personal care products (lipstick, make-up, shampoo, etc)? Are you feeding some of your pet wheat/gluten-containing pet food?

If gluten is really not the cause of your symptoms, you may look into FODMAPs (found in your apple, cabbage, nuts, berries, mango, celery) and SIBO (small intestinal bacterial overgrowth common in people with digestive disorders like celiac disease).

I recently had a similar reaction when I ate (what I now realize was too many) macadamia nuts.

It's hard to say, though. How was the cabbage prepared? The cruciferous veggies can be tough to digest.

Aliens..........

Have you ruled this out?

Looks like a lot of PUFA to me. How's your fat-soluble vitamin intake?
