Self-promotion is the way you get your ideas in front of the public. Even biomedical ethicists do it. I myself, a practicing nonscientist, experienced an internal conflict during the time I was a top scientist's right-hand man. The distinguished Bruce Ames at Berkeley is on board. Now his group is investigating a reported high frequency of folate deficiency and brain damage.
Epidemiology is on board.
New York Times health columnist Jane Brody is on board. The vitamin peddlers are on board, too. But they claim they always were. Science is just playing catch-up. No one really knows whether folic acid, chromosome damage, and cancer and other diseases are all connected.
