It's a nice anecdote, but I've lived and travelled in various African countries and never been sick from consuming fruit, vegetables or pressed juice. I'd be much more worried about eating poorly butchered and stored meat. The idea people throughout history didn't eat raw fruits and vegetables is also quite wrong.

Again, after living in rural communities, they largely eat what they can get - which includes a lot of raw fruits and vegetables. Of course meat is important, but no more important than nuts, berries, tubers etc.
