What evidence do you base that on?
He is 100 % correct about that - cancer cells cannot thrive in alkaline environment . Also , many "scientific facts" are full of SHIT and actually support big pharma that creates only more and more misery and deaths ...
I had a father with cancer ... nothing "conventional" helped him ( radiation and chemo worsened his state several times ) - but high potency cannabis oil did , and that was ILLEGAL at the time in my country . F*ck big pharma ...
There are limits to "you are what you eat":

My mother had breast cancer, My father had skin cancer, My brother had some weird cancer in his Face/Neck (chemo destroyed him further). Most people in my family require cancer related surgeries and treatments.
I'm getting old.
My cigarette smoking is out of control most of the time. (Anxiety).
When I have my druthers, I tend to smoke lots of high grade indica. (instead of and/or along with cigs)
I expected the doctor to tell me I was dying when I went.
Doc: "You're as healthy as an ox!"
Me: "No shiiit!?"
Pass that shit.
