Maybe they're too paranoid to have a web site.
Back in the 1950s, to my recollection, almost all health- food-nuttery, if you want to call it that, was right-wing, to put in mildly. When I first became interested in the subject, most liberals and, I suppose, leftists had complete faith in Science-with-a-capital-S, the government and America's corporate leadership in such matters. (Hence the dietary advocacy provided by public schools represented the four largest agricultural/food-processing lobbies.)
In the 1970s I used to buy raw honey from an old guy who thought Goldwater and Reagan were commie sell-outs. Alas, he too has long since sold out and gone away, or I'd ask him about The Spotlight.
