Thanks for bringing this up! Actually, your struggle has great significance to the forum. It illuminates the way diet and religion are intertwined, and how they can sever close relationships.
I'm sorry to hear of your fight; sounds like a harrowing experience. You cook his meals and your own meals? That's dedication, Maba.
Today I watched the "Sugar: The Bitter Truth" and your predicament came to mind.
Even though this may *not* be the best time to do diet wars with your husband, perhaps--when you sense the time is right--you could offer an invitation. Something like: "I don't want to fight over this issue, and I apologize if I've been too militant about it. Please don't take what's on my plate as a personal judgment on you. You did ask me for scientific information, so I found some and I just have one request: If you feel like it, could you please do me a favor and watch this lecture by an endocrinologist at a well-respected university [give the name and credentials of the doctor]? I'd really like to learn your opinion on this, even if you disagree with the lecturer. After this, we don't ever have to speak about what we eat if you'd like."
Of course, at this point, asking him to see the documentary may be too much. It may well be that sitting down with a marriage counselor who'd help both of you to listen to one another and to learn from each other without judgment is the best solution.
