This week’s New York Times Magazine is the annual food issue, and a bit of it is online already. Michael Pollan previews some of the food rules he’s compiled for an upcoming book (“No second helpings.”), and Jon Gertner examines an ongoing NIH study in which people cut their caloric intake by 25 percent to see how it affects the aging process. Bummer fact: “If you are lean because you are exercising, of course you are doing good, because you’re preventing types of diabetes, some kinds of cardiovascular disease and maybe some types of cancers,” says Dr. Luigi Fontana. “But the data suggest that calorie restriction is more powerful. And the people on C.R. are more powerfully protected from diseases than the exercisers.”
