Thank a thousand times for your advice evehard, sabertouth and Thler. I checked all the links and options and I m surprised how much gras fed beef and bison and lamb sources are in the USA. Seems to be the paleoparadise. Here in France it is very difficult to find 100 % grass fed animals, it was very difficult to find a reliable source. I think you are right, Evenhard, just for a couple of days whole foods will be good enough. There is a big wholefoodstore just 10 min from the hotel. I saw that there are even some restaurants with grass fed burgers, thats amazing, perhaps I will try them.Yes Tyler, I think I will mostly stick to wild clams and fish and oysters as you suggested and for the fat I hope to find marrow bones or very fatty meat at whole foods.
What about pastured eggs in america, are they really not grain fed?
I will be one day in London before going to america. Is there a place where they sell grass fed beef in London?
