新的研究有助于正在进行的争论对鸡蛋是好或对你的糟糕 - 而且这次,这个消息并不阳光充足。

研究,于2021年2月出版PLoS Medicine那found that every additional half每天的参与者与所有原因的过早死亡风险增加7%。此外,每天额外300毫克(Mg)胆固醇与早期死亡的风险增加19%。

On the other hand, researchers estimated that replacing half an egg each day with egg whites or egg substitutes would reduce the risk of premature death from all causes by 6 percent. They furthermore reported that swapping in otherprotein sources那like poultry, fish, nuts, and legumes, could curb the risk of dying early by 8 to 13 percent.

研究人员估计,研究人员估计,近似三分之二的早期死亡风险的过早死亡风险增加。

这study wasn’t a controlled experiment designed to prove whether or how eggs might directly prevent or cause health problems. And because researchers relied on study participants to accurately recall and report on their eating habits, it’s possible that some people provided inaccurate information about their own egg consumption.

来自此研究的结果study published in March 2019 in the美国医学协会杂志还检查了鸡蛋和胆固醇的风险。本较早的研究发现每天消耗的每一半鸡蛋与所有原因的死亡风险增加了8%,每次额外300毫克胆固醇都与过早死亡风险增加18%。

“你根本不应该吃大量的鸡蛋,特别是蛋黄,大多数胆固醇所在,”说Michael Hill,MD是加拿大卡尔加里大学的卡明医学院神经科学教授的教授。

“如果由于其他危险因素,例如家庭历史或家庭历史,或者hypertension“,”山博士说,山博士没有参与这项研究。

冲突研究 - 以及建议 - 关于鸡蛋

如果这个建议和这些最新的学习结果违背了你认为你对鸡蛋的看法,不要担心。真实的是,关于卵消耗潜在益处和卵消耗危害的大量研究产生了不一致和相互矛盾的结果,结果Jean-Philippe Drouin-Chrier,Phd,Rd那a researcher at the Institute of Nutrition and Functional Foods at Laval University in Quebec, who wasn’t involved in the latest study.

For the latest study, researchers asked 521,120 adults to complete dietary questionnaires when they were 62 years old on average, then followed them for up to about 16 years. During this time, 129,328 people died, including 38,747 deaths from cardiovascular disease.

这种方法的上行程序是它包括大量的人,并专注于越来越多的成年人,这些成年人正在增加心血管疾病,癌症和其他可以迅速死亡的其他条件的风险,使得更容易检测死亡率的有意义差异研究团队指出,与不同的饮食习惯有关。

但这项研究的缺点是人们一次只分享他们的饮食习惯,多年来他们的饮食变化,Drouin-Charter博士说。而且,在研究中吃了更多鸡蛋的人也更有可能有其他危险因素进行早期死亡,例如obesity那smoking, and unhealthy eating patterns.

一些研究发现鸡蛋无害,甚至有用

一large研究,在2020年1月发表的美国临床营养杂志found that eating an egg every day wasn’t associated with an increased risk of心脏病strokes那or premature death. Most of the participants were around 50 years old — about a decade younger on average than the people in the current study.

其他study, published in May 2018 in,还在五十年代兴起了人们,发现每天吃大约一个鸡蛋的人可能会产生11%的可能产生心血管疾病,而且可能死于这些疾病的18%,而不是从未吃过鸡蛋的人死于这些疾病。

这些研究可能发现鸡蛋无害,因为它们是在太年轻的人中完成了心脏病发作和strokes,David Spence,MD表示,冲程预防Atherosclerosis加拿大安大略省伦敦Robarts研究所的研究中心。

目前的研究更好地了解鸡蛋影响疾病和长寿的更好信息,因为参与者年龄较大,患有疾病的风险high cholesterollike心脏病和certain cancers, says Dr. Spence, who wasn’t involved in this study.

“临床相关问题不是青少年可以逃脱吃蛋的时间;它是人们是否有心脏病发作的风险strokesshould limit their intake of eggs and cholesterol,” Spence says.

专注于你的整个饮食,而不仅仅是鸡蛋

While the science from eggs may not be settled, many experts agree that the best way to live a long and healthy life is not by focusing on whether a single food is good or bad for you, says安德鲁·奥达加德,博士,英里/小时是加利福尼亚州加利福尼亚大学卫生科学副教授。

“Focus on the overall dietary pattern,” says Dr. Odegaard.

Eggs as part of an overall心健康饮食那for example, may not necessarily increase your risk of dying young or make you more likely to have a heart attack or stroke, Odegaard says.

根据2019 recommendations from the American Heart Association。Eggs were not associated with an increased risk of cardiovascular disease in research reviewed by the AHA to draft these guidelines.

适度的鸡蛋是各种饮食的健康部分,如膳食方法阻止高血压(破折号)饮食or aMediterranean-style diet。这些都是饮食,强调消耗水果,蔬菜,全谷物,植物油,坚果,鱼类和家禽,并限制红肉,加入糖和盐。

Many studies over the years have linked the heart-healthy Mediterranean and DASH diets to a longer life.

2015年的研究British Journal of Nutrition例如,老年人近十年后,发现他们的可能死于所有原因或从心脏病攻击或抚摸时的攻击地中海饮食。其他study, published in 2017 in新英格兰医学杂志那followed older adults over more than a decade and found people who changed their eating habits to more closely resemble a Mediterranean or DASH diets associated had a lower risk of death from all causes and from cardiovascular causes in particular.

但如果你每天早上有鸡蛋的鸡蛋,那么由于你的饮食习惯,你可能确实可能增加了心血管疾病的风险和由于你的饮食习惯而导致的。在这种情况下,降低蛋消耗并不像使整体变化更加变化,以使整个饮食更健康。例如,享受鸡蛋或旁边的绿色床旁边的鸡蛋和新鲜水果的一侧可能是正确的方向的移动。

“If frequent egg consumption is occurring in the context of a typical Western dietary pattern with high levels of refined grains, added sugars, red and processed meats, and ultraprocessed foods, then the best evidence for cardiovascular health is shifting one’s overall dietary pattern to a more healthful pattern, such as the DASH or Mediterranean diet, not focusing on eggs,” Odegaard says.
