Eat Nuts And Live Longer

Are you averaging at least one ounce of nuts per day?

BOSTON— In the largest study of its kind, people who ate a daily handful of nuts were 20 percent less likely to die from any cause over a 30-year period than were those who didn't consume nuts, say scientists from Dana-Farber Cancer Institute, Brigham and Women's Hospital, and the Harvard School of Public Health.

...

"The most obvious benefit was a reduction of 29 percent in deaths from heart disease – the major killer of people in America," said Charles S. Fuchs, MD, MPH, director of the Gastrointestinal Cancer Center at Dana-Farber, who is the senior author of the report. "But we also saw a significant reduction – 11 percent – in the risk of dying from cancer," added Fuchs, who is also affiliated with the Channing Division of Network Medicine at Brigham and Women's.

Whether any specific type or types of nuts were crucial to the protective effect couldn't be determined. However, the reduction in mortality was similar both for peanuts and for "tree nuts" – walnuts, hazelnuts, almonds, Brazil nuts, cashews, macadamias, pecans, cashews, pistachios and pine nuts.

The reduction on death rate is dose-dependent.

"Compared with those who did not eat nuts, individuals who consumed nuts (serving size of one ounce) seven or more times per week had a 20% lower death rate and this association was dose-dependent," stated lead author, Ying Bao, MD, ScD, from the Department of Medicine, Brigham and Women's Hospital and Harvard Medical School, Boston, MA. "Those who consumed more nuts were also leaner, and tended to have a healthy lifestyle, such as smoking less and exercising more," added Dr. Bao.

Eating nuts just once per week gives 11% reduction in death.

And, adding nuts to one's diet seems to cause weight loss, despite the additional calories!

As the old snake oil salesmen used to say, "good for what ails you!".

hmmm. Maybe snake oil, like nuts, is high in EFA's...

What if it's just the healthier lifestyle, and not the nuts, that are extending lifespan?

BillB,

From the first summary:

"Sophisticated data analysis methods were used to rule out other factors that might have accounted for the mortality benefits. For example, the researchers found that individuals who ate more nuts were leaner, less likely to smoke, and more likely to exercise, use multivitamin supplements, consume more fruits and vegetables, and drink more alcohol. However, analysis was able to isolate the association between nuts and mortality independently of these other factors."
