I’m reading the new expose of the vitamin and supplement industry, “Natural Causes,” by Dan Hurley. For someone who doesn’t have much faith in the medical establishment, this book is a real bummer. Now I can’t have any faith in the natural remedies, either. Hurley tells the story of the original “snake oil,” and exposes Adele Davis (whose nutrition advice I followed when I was pregnant). According to him, Adele Davis heavily footnoted all her books to make herself look knowledgeable and scholarly.
