Yes, grain-fed meat causes psoriasis. 
Seafood is ok for me. I need 100% grass-fed meat.
Do you know an adres where i can order meat ?
You have a problem. Last I checked the Netherlands and Belgium had an extremely high population density, and therefore high food prices, and poor choices. Plus, ordering raw grassfed meat from abroad may prove difficult unless you can persuade German etc.farms to look the other way(if they're close to the Dutch border). Other than the last option, do try to obtain raw wild game(it's far superior to raw grassfed meats). Obviously depend on wildcaught seafood to some extent(I myself do so as I find that superior health is acheived with at least some portion of raw wild seafood)
*Just did some googling online and there does indeed seem to be some sort of a grassfed meat industry in the Netherlands:-
"•The fat from cattle raised on green grass has much higher concentrations of vitamin K2. Studies of K2 have suggested it is extremely potent for lowering arterial calcifications, which in turn lowers the risk of heart disease. The Rotterdam Study, which prospectively followed just over 4,600 men aged 55 or older in the Netherlands, showed that the highest intake of vitamin K2 was associated with a 52 percent lower risk of severe aortic calcification, a 41 percent lower risk of coronary heart disease (CHD), a 51 percent lower risk of CHD mortality, and a 26 percent lower risk of total mortality.

http://www.healthy-eating-politics.com/grass-fed-beef.htmlOther options include searching for an organic/grassfed meat association in the Netherlands etc. In short, whenever I hear newbies claim shortages of high-quality raw foods such as grassfed meats I'm generally highly sceptical of such claims as I felt the same way when I was in London, UK at the start of this diet, and, because of strenuous effort on my part re googling grassfed farms, visiting farmers' markets/health-stores/organic butchers etc at least once a week or more, I was able to find numerous excellent sources of high quality.
