It is not hard to find grassfed beef and fat in Europe. At least it was not for me..... I even get some here in Finland, finally. But that was harder lol We also have own 100% grass fed/hay fed sheep that we kill ourselves with lots of fat on them.
Also, fatty fish is not hard to get if you live close to water... (I believe our ancestors did this, they clearly choose to live close to water)
I wonder how GCB was not observant enough to change up his WOE/way of living before he got tumors. As the scientist he is you would think he observed himself pretty closely, especially as an instincto. I wonder about this.
F.ex. I soon can see it on my skin, eyes, hair, teeth, moods, energy, sleep... etc. if I did it right or wrong. Before any illness or more serious stuff like having to use surgery. And when I see things move in the wrong direction I change what I do. At least for me it has worked great to do like this for the last half part of my life... I let my body tell, in addition I do research for sure. And I let the nature guide me. It is very wise. I also do blood works, to not fool myself. I wonder if GCB do regular blood works too? Those often tells you things are going in the wrong direction even before you realize it.
I really think to eat much sugar is dangerous together with computer work or living in a city in today's world. We should stop thinking we are apes and start thinking evolutionary/scientifically how the world has changed and what are our needs as human today, we have a totally different brain and gut than apes.. and apes are living a totally different life than we. Using no technology, no clothes... etc. I get tired to hear those arguments, we are primates and we need to eat like them. Very stupid argument IMO. I guess we hear it from people that wants to justify their sugar addiction.
