Nassim Nicholas Taleb, the man is even afraid to drink orange juice, because it's too modern and untested for him:

"Taleb's hatred for orange juice is an example of a wider disdain for the modern diet. He reveals his personal food rules, and very fascinating they are: no liquids that have not existed for at least one thousand years (i.e. wine, water and coffee only), no fruit not present in the ancient Mediterranean (no pineapples, pawpaws or other exotica)"

So I think we can write off Taleb's fears as totally nuts.
