Diet Containing Lots of Eggs May Be Linked to Heart Disease
A new report links eating eggs to an increased risk of heart disease. The results follow several earlier studies that found eating eggs was generally healthy.
The JAMA Network Open published the new report in March. It combines data from six other earlier studies. It shows a 6 percent increased risk of heart disease when the average number of eggs a person ate each day increased by half an egg.
Norrina Allen, who co-wrote the report, is an associate professor of preventative medicine at Northwestern University's Feinberg School of Medicine in Chicago.
She told the Reuters news service that, in the United States, eggs are generally one of the top sources of cholesterol in a person's diet. Individuals with higher levels of cholesterol in their diet are at increased risk for the development of heart disease later in life, she said.
However, Allen added that she would not say that eggs are completely unhealthy.
"I'm not advocating people take them completely out of their diets," she said. "I'm just suggesting that people eat them in moderation."
Allen's team examined data gathered from six studies that involved a total of 29,615 people. Earlier researchers had followed these people for an average of 17.5 years. At the start, the people answered questions about the foods they ate. But they were not asked about their diets at any time after that.
Over time, there were 5,400 cardiovascular-related incidents among the group. This included 2,088 deadly and non-deadly heart disease events and 1,302 deadly and non-deadly stroke events. It also included 1,897 deadly and non-deadly heart failure events and 113 other deaths from cardiovascular disease.
After examining the data, Allen's team found a link between egg consumption as reported at the start of the study and people's risk of developing heart disease. As their egg consumption rose, so did their risk.
Some experts believe the new study does not prove that eggs were causing heart disease.
Cholesterol's role in the development of heart disease has been discussed for more than 30 years, said Dennis Bruemmer. He is a heart specialist with the Heart and Vascular Institute and an associate professor of medicine at the University of Pittsburgh Medical Center. Bruemmer noted that several past studies have tried to measure how much of the cholesterol in a person's overall diet comes from eggs. Each has produced different results.
"This study does have clear limitations, including self-reporting at a single time point," he added. "This limits its validity."
Eggs contain a lot of cholesterol - about 200 milligrams. That is the highest daily amount recommended under current guidelines.
Bruemmer said, "Eggs in moderation are probably acceptable from a nutritional standpoint." Moderation, he added, is "less than one egg a day on average, including eggs in foods such as bread."
Holly Andersen agrees that the study has "real limitations." She is a heart specialist and director of education at the Ronald O. Perelman Heart Institute at the New York-Presbyterian/Weill Cornell Medical Center.
One issue Andersen has with the study is that a lot of the egg-eating people in the study also appeared to be eating large amounts of meats and processed meats.
"If you're consuming a huge amount of processed meats, it doesn't matter how many eggs you're eating," Andersen said.
Also, Andersen said, the study is observational, meaning it can only show there is a link between egg consumption and heart disease. But it cannot prove eggs are the cause of the disease. It may just be that people eating a lot of eggs are also consuming a lot of bacon, Andersen said.

艾伦的团队研究了涉及29615人的6份研究的数据7Bs__fh)5GdzRCwF。早期的研究人员对这些人进行了平均17年半的跟踪调查CSzz(TitOh;NQp=*!l1。刚开始,参与者回答了有关所吃食物的问题7f#ueVi=Qo)~+tSh。此后,他们再未被问及饮食方面的问题dLKaQ!|DQO8XhoV0QH

丹尼斯·布鲁默(Dennis Bruemmer)说,胆固醇在心脏病发展中所扮演的角色已经被讨论了30多年.-q|NJebppcR6t。他是心脏和心血管研究所的心脏病专家,也是匹兹堡大学医学中心的医学副教授Rd7Ln8K[-Dge@,。布鲁默指出,过去的几项研究试图衡量人们的饮食中有多少胆固醇是从鸡蛋中摄取的U(^G3e==Yel+faj]eO;。每一项研究的结果不尽相同%YdwlkvO*mDq+Z5k
他指出,“这项研究确实存在明显的局限性,包括在单个时间点做自我报告fKq(46*QgeIw(a。这一点限制了其有效性MA%F(Kjd9]X9N1.。”
鸡蛋含有大量胆固醇——一个鸡蛋约含200毫克胆固醇[ZJVVJMZ(2Ntfk。这是目前饮食规则中所建议的胆固醇最高日摄入量0unQi38Y1@DF2
布鲁默表示“从营养的角度看,适量食用鸡蛋是可以接受的uRd|*bQ^ltla6y]8。”他补充说,“适量”是指“平均每天食用的鸡蛋不超过一个,包括面包等其他食物中所含的鸡蛋#QGxEtH!loN9%x。”
