You say they don't listen to your arguments, so what's the point? Just say you don't want to talk about it and leave it at that. No argument is more compelling than obvious, vibrant health.

"i didn't....."

Since you're Norwegian, you've actually had less than 10,000 years with grains in your diet. Remember, agriculture didn't happen all at once--it began in the Fertile Crescent, then slowly spread to Africa, Asia and Europe. The Roman Empire is the party at fault for the spread of agriculture in Europe, and even they didn't make it as far north as Scandinavia! That was as recently as 2,000 years ago. I've no doubt that Nordic peoples led a much simpler hunter/gatherer lifestyle for longer periods of time compared to the rest of Europe.

I think there is a spectrum. I'd suggest watching this Ancestral Health talk by Mat Lalonde - he addresses this question in the presentation."An organic chemist's perspective on paleo" http://vimeo.com/27570335

Another great talk to watch is the on on dairy, brings up some scary stuff about today's milk. 'Dairy hormones and human health' http://vimeo.com/27671369

You probably won't convince them, no matter how brilliant your arguments or how compelling your evidence. Over time, when you are lean, strong, and fit; and they are fat, weak, and sick, the evidence in front of them may get them to reassess. Unfortunately, most people, when confronted by such evidence, will still pretend that their eyes deceive them. Paleo is much too much of a leap for most people in Western societies.

For me personally, if I can tell it will fall on deaf ears I really don't bother. However, if some one genuinely seems interested I tell them this... which is total TMI and it usually shuts them up if they are being snarky... My whole family is gassy. Not even like oop a lil fart like stinky nastiness that is truly embarrassing. I too was plagued with the problem up until I started paleo. When I started paleo the first week I think I farted just 2 times daily. 2 times!! It was glorious, I am ashamed to even think how much I broke wind before paleo. After playing with paleo for a while I have found that I don't have much problems with legumes but all problems with dairy and wheat (not that I encourage legume consumption) and through this have realized what gives my body problems. Anyways, my point is tell them your story with it. What changes have these things made in YOUR diet that have bettered your health. You can give them the science after that cause they won't care till they see some results. :) Goodluck showing those grain heads whats up!

Well, for one, you can say that industrial grains and milk are not remotely like the grains and milk your ancestors may have adapted to! See Michael Rose's 55 theses for more good stuff.

If they are not interested in learning...don't bother. Even on the reservation where diabetes, renal failure, dialysis, diabetes related amputations, etc... are an epidemic many simply aren't interested in learning. And the American Indian, some Celtic peoples, Nordic people, etc... are NOT adapted, 200-600 years simply isn't long enough for natural selection to kill off those who can't adapt before they get to pass on their DNA and modern medicine stops natural selection anyway.

Just be as healthy as you can and do what I do, even though they aren't interested so I don't bother trying to tell them, they ALL want to tell me how not eating pizza pasta, bean bread, fry bread, etc... is unhealthy for me I point out my own excellent health and say, "what I'm doing is working for me." Then I point out their health and fitness level and say, "and the fry bread isn't working for you."

Otherwise, when they aren't trying to "educate" me...I just leave it alone.

Why the obese and unhealthy feel the need to educate us about how to eat and exercise, I'll never understand.
