On the one hand, it's an incredibly brilliant feat -- stealing an entire subculture in a consumer market away from the mainstream diets. On the other hand, trying to show how "science" backs up the ancient dietary restrictions from the Book of Leviticus just screams dogma and denial. (Because, of course, only the science we selectively agree with justifies God's eternal wisdom... The evidence that doesn't jive with the doctrine is just plain persecution.)
If you flip through the diet guidelines, though, it's the same "eat organic foods and exercise" regimen that non-religious hippies and yuppies alike have taken up as a lifestyle mantra. It just has the tagline Because God wants it that way added. (Forgive those on Atkins and South Beach, Father, for they know not what they do).
From an environmental standpoint, this could be good news: more consumers are buying organic foods and (ostensibly) making informed decisions! The "Eco-Christian" movement has its merits, after all. But it's a little disturbing to see a particular diet become such a trend in communities of faith only because a religious person markets eating healthier as a scriptural mandate.
Hey, if people are living healthier lifestyles, who am I to judge?
I were Michelangelo, though, I think I'd have the right to comment...
