Can you explain a bit more? I'm interested, but I'm interpreting your post as "helps with DNA copying so its good for cell reproduction means it causes cancer". I'm sure I have it wrong. I mean.... loads of things we eat are good for cell reproduction. It's almost like saying "living makes you more likely to die"
Note the reference to methionine. My understanding is that the body recycles methionine as well. So give your body just enough to let it do it's thing but don't pour gasoline on the cancer fire by supply a surplus of a critical component.
I'm still slowly doing the research on this. It was spurred by my daughter telling me about "the Blue Zone healing cancer". Googled that, and checked out the dietary element, and that led to the topic we're discussing now.
It seems reasonable enough. And simple enough. And you don't have to be vegan, but mindful of intake.
Just trying to share a recent discovery that seems like a possible life changer.
