The sleep bits are (probably - don't know very much about the topic) ok, but once it gets to diet, it goes right into la-la-land. It is riddled with misinformation and the belief that a "raw food diet" fixes all. A raw food diet might make you lose weight, and it might get you food poisoning, but that's about it. For more information, I recommend C0nc0rdance's youtube videos on raw food.
For other clearly wrong, or wrongly interpreted information: While 70% of the population is lactose intolerant, that doesn't mean you are. We do know that about 99% of the Chinese population is lactose intolerant (which proooobably skews the numbers a bit), yet, for example, only about 1% of Dutch people are lactose intolerant. Northern Europeans and other people from historically very dairy-rich cultures have a very high degree of lactose tolerance, and persistent lactase production (the enzyme that digests lactose and makes you lactose tolerant). Very interesting genetics topic :) Statistics will not say anything useful about whether you are likely to be lactose intolerant, but ethnicity will. Get tested if you are in doubt. It's a simple test. Just make sure you go to a qualified medical practitioner.
As for gluten insensitivity, this is called coeliac disease and is very serious. Thankfully, the highest estimate for prevalence is about 1%, not 15%. The anti-gluten brigade has been on it for years, but non-coeliac people can and should eat gluten. It's a good protein of high quality and makes your bread dough stick together. That's why it's hell trying to bake gluten-free bread or pizza dough.
Casein, a milk protein, is also not a bad protein. While there are many scare stories about casein (it being blamed for autism, cancer, et cetera), they don't hold up very well. Casein is a nice, slow-digesting protein with a very good quality, as any body builder who does the diet/protein thing will be able to tell you. Drink your milk if you can tolerate it, and eat more cheese :)
As for multiple sclerosis, we actually don't know what causes it other than that there likely is a genetic component, but that other factors also interfere. For the actual, REAL long term effects of coeliac disease, see here: http://celiacdisease.about.com/od/symptomsofceliacdisease/a/...
As for cortisol, your body regulates this itself. If you're stressed, stress down. But if your body doesn't regulate itself, you have a huge problem and need to see a doctor right away.
While "eat food, not too much, mostly plants" is very good advice, there's also another piece of advice that has been forgotten: "You are probably not sick, and your body can take care if it." Just eat a normal, healthy diet.
Man. That was long. Sorry about that, but I had to get some facts out.
Gluten sensitivity ranges from the coeliac disease on the extreme end of the continuum down to mild inflammation of the small intestine. Gluten sensitivity is NOT just about coeliac disease. There is a growing body of evidence that gluten is in fact a problem in our diets and it's not as clear cut as you present that if you don't have coeliac, you can eat all the wheat you want. I'm not sure there's any "should" to eating wheat/gluten. There are other more nutritional ways to get protein.
Since this is an article on hacking sleep, I think it's worth mentioning. Try dropping gluten/wheat/bread from your diet for 30 days and see if your sleep improves. I know that mine has. If it doesn't, great, you are golden. If it does, you've learned something.
Facts or not, the article is about improving your sleep. Some people are sensitive to dairy and wheat. Try going without them for 30 days and see what happens. It's all a big experiment.
In the U.S. at least, a normal, healthy diet is something of a contradiction. Michael Pollan wouldn't need to promote "eat food, not too much, mostly plants" if people were doing it already. I agree with you completely on your other points, but telling some people to eat a "normal" diet will be interpreted as, "eat out of fast food restaurants and freezer cases," because for many in the U.S., that is a normal diet.
Oh, a "normal" diet varies a lot depending where you are. Myself, I'm in Norway, and the diet here is fairly healthy if somewhat short on vegetables (especially during the winter). I'm sure most other "normal" diets in the world are quite ok, as well. Might need some added vegetables, depending on where you are (the Dutch probably don't need any extra), but mostly, people who are able to afford normal amounts of food will eat better than one would expect given the media hype. They might want to cut down on the amounts, and cut out the sugary drinks, but I think that's it.
Is kale available in Norway? According to most sources (for example, this simple comparison chart: www.wholefoodsmarket.com/pdfs/superfoods.pdf), kale is a super food, and in the US at least, grows well during the winter months.
If you consider a normal, healthy diet as "eat out of fast food restaurants and freezer cases," then sleeping problems are probably not what you should focus on first.
