A popular Facebook link this weekend has been this New York times article on sugar, claiming that sugar in any amount is not only unhealthy, but is toxic in exactly the same sense as any recognized poison. So who am I supposed to believe? The New York Times guy (who is identified as a “researcher” and an “investigator” but never as a scientist — anybody, however inept or untrained or off-balance can call himself a researcher. I oughta know; it’s what I call myself) — or this 1950 ad from the Children’s Friend? C’mon, who am I supposed to believe??
