Raw food and Atheism

Christianity, and to some extent other religious or spiritual convictions generally accepted in the West seem to be very common in the raw foodist circles.

Myself being a convinced atheist find this puzzling, and would now like to see whether I'd find any non-religious raw health enthusiasts around.

Surely there must be others out there who base their beliefs on merely natural order, and find their comfort and joy in more earthly, socially bound philosophies?

Looking forward to hearing from you guys!
