This thread is for anything Paleo/Primal/Ancestral related that you know of in Belgium.
Supermarkets, farms, doctors, gyms, anything goes. Please create one answer per item group that you know of.
(Since Belgium is the only region I care about, I hope this catches on and other people will create threads for their region)
GREAT meat to find at veeakker. They are situated in Leuven but have other places they deliver to. Service is great, the beef/lamb/fish (e.g. wild alaska salmon) couldn't be higher quality. The prices can be high but you can always supplement your diet with organic, cheaper meat. Maybe even horse meat.
You can go to the BioPlanet to find practically everything you'd need, except for grass-fed stuff and probably bones too.
If you live near Grimbergen there is the "Groentehof" that have GREAT vegetables and fruits (this store closed because the owners retired, but they still sell apples). And for supplements, I just use iHerb.
To be honest, I never go to any supermarket. Just the butcher and vegetables at the organic store.
I get oysters from crown prince on iHerb. Some supermarkets (eg. Delhaize) also carry organic fruit and Haagen-Dazs (okay not that paleo but it comes close). Oysters can also be found in the Delhaize but it's crazy expensive and you have to open the shells yourself which broke 4 of my knives :).
Butter: You can get Kerrygold butter in at least Colruyt, Carrefour and Delhaize. Colruyt is cheapest if you buy per 4.
Note that Kerrygold may or may not be really good grassfed butter. The Quilt tested several batches and they had varying K2 content :-(.
Jack O'Shea's in Brussels has grass-fed organic meat.
http://www.ourobouros.be/: Orrobouros is an organic vegetable farm in Flanders. They have stands on market day in Jette and Place Chausseur in Brussels.
This time of the year, Colruyt has nice and very reasonable priced game meat (epsicially the frozen meat is great)
Kerrygold is widely available. At Bioplanet they have Dutch grass fed butter, but more expensive. Bioplanet bacon is good.
Grass-fed/pastured meat is difficult, but as Korion said, Veeakker has nice but expensive 'natuurpunt' meat.
I haven't tried it, but 'Modderbaard' has a nice blog with lots of Dutch grass fed meats. Maybe worth trying.
I know there are some cross fit gyms around.
I don't know of any doctors at all, I only know of one physical therapist who is paleo inspired: me! ;)
In Antwerp I found a small Euro-Asian supermarket in the Driekoningenstraat that has cheap ghee (€5/500g) and coconut oil (€3/500ml). They also have lots of exotic vegetables and very sticky rice :)
So in general I would say, check out your local asian supermarkets.
In addition to Asian stores, I find African stores to be a great help as well! Spices, alternative flours, oils... The ones I shop at are called "Kausar Ethnic Beauty" (yes, they sell makeup and wigs as well :p)
I'm trying to find some grass-fed beef in Belgium. Can someone explain veeakker to me? They deliver to the food store? Do you know if any speak english and/or are open on the weekends. I live in Mons, so by a quick glance, it seems I'll be driving a little. Thanks!
