People who eat nuts tend to live longer than those who don’t eat them, concluded a large 30-year Harvard study of health care professionals, recently published in the New England Journal of Medicine. The more often people ate nuts, the greater the benefit.
The biggest effect was seen in reduced deaths from cardiovascular disease; the cancer death rate was also lower among nut eaters. People who ate more nuts tended to be leaner and more active, consumed more produce, and were less likely to smoke than nut avoiders. But even when the researchers controlled for such factors, nut eating was still associated with reduced mortality rates.
