"Food, after all, is the one and only construction material for the growing bodies and developing brains of our children. Who among us would sanction building anything we care about and hope to see last—house, car, computer—from junk? How, then, do we tolerate building the bodies of our children and grandchildren from such dubious material?
We would allow no such transgression with other species. Imagine, for instance, surreptitiously slipping artificially colored, artificially flavored loops, masquerading as having something to do with real fruit, to a real toucan. The zoo authorities would, I trust, escort you off zoo grounds—if not in handcuffs—before you could say “red dye number 40.”"
