Too Many Eggs Risky?
Study Shows Higher Death Rate Among Men Who Eat 7 or More Eggs per Week; Egg Advocates Unconvinced
April 9, 2008 -- The on-again, off-again debate about eggs and health has
been cracked open again by a new report on death and egg consumption.
On the one hand, the study shows a higher death rate among U.S. men who eat
seven or more eggs per week, especially among diabetic men.
But on the other hand, the study, published in The American Journal of
Clinical Nutrition, shows no link between egg consumption and heart attack or stroke. And eating up to six eggs
a week didn't affect men's health.
What to make of it all? The higher death rate linked to eating seven or more
eggs per week is "surprising" and needs to be confirmed, notes an
editorial published with the study.
"Remember: eggs are like all other foods -- they are neither 'good' nor
'bad,' and they can be part of an overall heart-healthy diet," writes editorialist
Robert Eckel, MD, of the University of Colorado, Denver.
The study included 21,300 male doctors followed for 20 years, starting when
they were about 54 years old, on average.
Every year during the study, the men noted their egg consumption, physical activity, smoking, alcohol use, consumption
of vegetables and breakfast cereals, diabetes, high blood pressure, and use of
Participants weren't asked to change their diets.
The typical participant reported eating one egg per week. Older, heavier, less
active men who smoked, had high cholesterol, and had a
history of diabetes and high blood pressure tended to eat more eggs.
The researchers -- who included Luc Djousse, MD, MPH, DSc, of Boston's
Brigham and Women's Hospital and Harvard Medical School -- counted 5,169 deaths
among the men during the follow-up period.
Even after adjusting for other risk factors, men who reported eating seven
or more eggs per week were 23% more likely to die of any cause during the
study; the risk rose among those with diabetes.
But egg consumption wasn't linked to increased risk of heart attacks or
strokes, even among men who ate more than seven eggs per week.
Djousse's team calls for further studies to investigate their findings.
Egg Advocate Responds
Donald McNamara, PhD, is the executive director of the Egg Nutrition Center,
which is backed by the American Egg Board and the United Egg Producers. He
raises three key points about the study.
"First off is that we don't know what they died of," McNamara says.
"We know it wasn't related to cardiovascular disease or strokes. But we
don't have any information about what it really was related to."
"I can't imagine that eating more than 6 eggs a week is going to cause
you to drive off a bridge or speed," McNamara says. "It doesn't have a
rational biological mechanism at this point that I can really put my finger
