Seven or more eggs a week linked to death risk

Seven or more eggs a week linked to death risk

Middle-aged men should limit consumption, study suggests

WASHINGTON - Middle-aged men who ate seven or more eggs a week had a higher risk of earlier death, U.S. researchers reported on Wednesday.

Men with diabetes who ate any eggs at all raised their risk of death during a 20-year period studied, according to the study published in the American Journal of Clinical Nutrition.

The study adds to an ever-growing body of evidence, much of it contradictory, about how safe eggs are to eat. It did not examine what about the eggs might affect the risk of death.

Men without diabetes could eat up to six eggs a week with no extra risk of death, Dr. Luc Djousse and Dr. J. Michael Gaziano of Brigham and Women's Hospital and Harvard Medical School found.

"Whereas egg consumption of up to six eggs a week was not associated with the risk of all-cause mortality, consumption of (seven or more) eggs a week was associated with a 23 percent greater risk of death," they wrote.

"However, among male physicians with diabetes, any egg consumption is associated with a greater risk of all-cause mortality, and there was suggestive evidence for a greater risk of MI (heart attack) and stroke."

They urged more study in the general population.

Neither 'good' nor 'bad'
Eggs are rich in cholesterol, which in high amounts can clog arteries and raise the risk of heart attack and stroke.

One expert on nutrition and heart disease said the study suggests middle-aged men, at least, should watch how many eggs they eat.

"More egg on our faces? It's really hard to say at this point, but it still seems, if you're a middle-aged male physician and enjoy eggs more than once a day, that having some of the egg left on your face may be better than having it go down your gullet," said Dr. Robert Eckel of the University of Colorado and a former president of the American Heart Association.

"But, remember: eggs are like all other foods — they are neither 'good' nor 'bad,' and they can be part of an overall heart-healthy diet," Eckel wrote in a commentary.

More likely to drink, smoke
The Harvard team studied 21,327 men taking part in the much larger Physicians' Health Study, which has been watching doctors since 1981 who have agreed to report regularly on their health and lifestyle habits.

Over 20 years, 1,550 of the men had heart attacks, 1,342 had strokes, and more than 5,000 died.

"Egg consumption was not associated with (heart attack) or stroke," the researchers wrote.

But the men who ate seven eggs a week or more were 23 percent more likely to have died during the 20-year period.

Diabetic men who ate any eggs at all were twice as likely to die in the 20 years.

Men who ate the most eggs also were older, fatter, ate more vegetables but less breakfast cereal, and were more likely to drink alcohol, smoke and less likely to exercise — all factors that can affect the risk of heart attack and death.

一星期吃超过7个鸡蛋与死亡风险的联系

        研究建议中年男人应该限制消费鸡蛋

美国研究员在星期三的报告称，华盛顿中年男子如果一个星期吃超过七个鸡蛋的话会有缩短寿命的危险。

依照美国杂志出版的关于经过20年研究的临床营养研究结果，患有糖尿病并且吃了鸡蛋的男人他们的死亡危险也全部都上升了。

研究补充一个成熟机体的证据，是关于吃鸡蛋有多安全的，但结果与它大相径庭，因为过去的研究没有发现鸡蛋对死亡风险的影响。

来自翰女子医院和哈佛医学院的Luc Djousse 博士和J. Michael Gaziano博士发现没有患糖尿病的男子就算一个星期吃六个鸡蛋，也没有额外的危险。

    "虽然一个星期达六个鸡蛋的蛋消费不能与全部的引起必死命运的危险联合一起 , 但是一个星期七个或更多的鸡蛋消费与高达 23% 的死亡危险有关 " 他们写道。"而且在患有糖尿病的男性之中，任何的蛋消费与引起较高必死命运的危险全部有关,并且为心脏病和中风的较高发作危险提供了暗示性的证据 ."因此他们催促在一般的人中进行更多的研究。

既非“善”也不“坏”

   蛋中富含胆固醇，当含量太高时就可能阻碍动脉而使心脏病和中风发作的危险提高。

有一个营养和心脏病上的专家说研究意味着中年男子至少应该看一下他们吃了多少蛋。"用多点的鸡蛋来做面膜？关于这一点真的很难解释，但是它仍然存在，但是如果你是中年男性病患者，而且每天享受超过一个鸡蛋，那留一些蛋在你的脸上好过让它进入你的食道”科罗拉多大学教授兼美国心脏协会前任主席 Dr. Robert Eckel说。

"但是, 请记住:蛋像所有的其他食物，他们不是“善”的也不是“坏”的，而且它们是心脏健康超载的食谱中的一员。" Eckel 在一个注释中写道。

更像喝酒和抽烟

哈佛团队在21327位男人中进行了更大范围的外科医学健康研究，这些男人自从1981开始都曾经在看过医生，而且答应报告他们的健康和生活型态。在 20 年内，这些人中有1550位心脏病发作, 1342位中风和超过5000人死了。

"蛋消费与心脏病发作或者中风没有联系 , " 研究员写道。但是一个星期吃了七个蛋或更多的男人，23%更有可能在 20 年期间死亡。而且吃了蛋的患糖尿病的男子是有可能在 20 年死去人数的两倍。

吃了很多蛋的男人也是比较老和胖的，他们虽然吃了较多蔬菜，但是少吃早餐和谷类食品，而且他们酗酒和抽烟，却少做运动。这些都是影响心脏病发作和死亡的危险的因素。
