Eggs: Three or more a day increase the risk of heart disease and early death, according to the study



"Eggs, especially egg yolk, are a major source of dietary cholesterol," wrote Victor Zhong, senior author and postdoctoral fellow at Northwestern University's Department of Preventive Medicine at the Feinberg School of Medicine in Chicago. In a study published on Friday in the medical journals JAMA, he and his colleagues found that a single large egg contains about 186 mg of cholesterol.

Researchers studied data from six US study groups, including more than 29,000 individuals who were followed for an average of 17½ years. In the follow-up period, a total of 5,400 cardiovascular events occurred, including 1,302 fatal and non-fatal strokes, 1,897 cases of fatal and nonfatal heart failure, and 1

13 other fatalities. Another 6,132 participants died from other causes.

The intake of 300 mg cholesterol in the diet was associated with a 3.2% higher risk of heart disease and a 4.4% higher risk of early death, as shown by the analysis of Zhong's data. And every other half egg consumed per day was associated with a 1.1% higher risk of cardiovascular disease and a 1.9% increased risk of early death due to any cause.

One possible reason for inconsistent outcomes in the past was the fact that other studies have not considered that egg consumption may be due to other unhealthy behaviors, such as low physical activity, smoking and an unhealthy diet. In addition, cholesterol-containing foods are usually rich in saturated fat and animal protein.

"In contrast, the current study included a comprehensive assessment of these factors," Zhong and his co-authors wrote.

In one beside The study published editorial Dr. Robert H. Eckel of the University of Colorado School of Medicine said that this topic was "important" to physicians, patients and physicians to the general public.

Why? "The association of egg consumption and cholesterol in food with [cardiovascular disease] has been debated for decades, but has recently been considered less important," wrote Eckel, who was not involved in the research. However, compared to the previously published analyzes, the new report is "far more comprehensive", with enough data to make it clear that eggs and the overall intake of dietary cholesterol are still important for the risk of [cardiovascular disease]and especially for all "From mortality," he wrote.

However, the relationship between eggs and the risks of heart disease and premature death is "modest," he said, because above-average consumption of cholesterol or eggs increases cardiovascular disease, such as stroke and early death The new finding is significant when looking at the total population, he said.

"Given the adverse effects of egg consumption and dietary cholesterol in the adjustment of heart healthy eating habits, the importance of limiting the intake of high-cholesterol foods should not be discounted," concluded he.

Zhong and his e co-authors similarly concluded, "These results should be considered when developing nutritional guidelines and updates.

Victoria Taylor, a senior nutritionist with the British Heart Foundation, told Science Media Center that "this type of study can only show an association and no cause and effect. "And more research is needed to understand the reasons for this connection." 19459004

"Eggs are a nutritious food, and while this study focuses on the amount we have, eating is just as important How the eggs are boiled and the ingredients that go with them, "said Taylor, who was not involved in the investigation." Healthy eating is all about balance. "
