Clod, will he eat fish? There's substantial evidence out there that omega3s have significant effects on autoimmune conditions... I will look for some links.
This article (
Omega-3 fatty acids in inflammation and autoimmune diseases) discusses the effect of omega3s on multiple inflammatory-upregulated disorders, many of them involving the gut.
Another one (
Dietary modification of inflammation with lipids).
Yet another (
Omega-3 fatty acids in inflammation and autoimmune diseases)
I can help you get a hold of any of these articles (or any others you might want).
Omega3s are also available in
high-quality supplement form if he doesn't like fish. I personally take 1g of EPA/DHA every day for diabetes-related systemic inflammation... My mom takes 2g/day for Crohn's disease, and my husband takes 2g/day to help with his psoriasis -- we don't want that to evolve into rhumatic arthritis! Check out LEF's ingredient list for any of his banned substances... They're one of the few suppliers I know that are this thorough.
Kudos to you, lady.
