Experts have wondered for years whether eating eggs is good or bad for health.
And it seems that the answer could depend on the number of people you consume per week.
Taking eggs more than three times a week can lead to increased cholesterol, resulting in cardiovascular damage and premature death, according to a new study from a group of physicians from different universities in the United States and published by the medical journal specialized JAMA.
This is due to the large amount of cholesterol present in the egg yolk: a large egg contains about 185 milligrams of cholesterol.
Three or four eggs
The new study badyzed data from six surveys with nearly 30,000 participants over 17 years old.
The researchers concluded that the daily intake of 300 milligrams of cholesterol in the diet increases the risk of cardiovascular disease by 17% and premature death by 18%.
According to the study, consumption of three to four eggs per week was badociated with a 6% increase in the risk of cardiovascular disease and an 8% increase in the risk of premature death.
And eating two eggs a day would increase the risk of cardiovascular disease by 27% and the risk of premature death by 34%, according to the study.

Despite the diet
These badociations are independent of age, level of activity, whether you are a smoker or not, or have high blood pressure.
In fact, researchers say that heart health does not matter to the rest of the diet: the more eggs you eat, the higher the risk of cardiovascular problems, illness coronary heart disease, stroke and premature death is high.
"Our study showed that if two people followed exactly the same diet and that the only difference was the consumption of eggs, that person would be more likely to suffer from heart disease," said the co-author of the study, Norrina Allen.
Does this contradict what we knew?
This new study contradicts previous ones that had established that higher egg consumption did not result in an increased risk of coronary heart disease or stroke.
According to Dr. Allen, these studies generally had a less diverse sample and a shorter follow-up period.
But researchers also admit that there may be measurement errors in their badysis.
Egg consumption data were collected using questionnaires or using a history of food. Each participant was asked what he had eaten in the previous year or month. The data in the study are therefore based on what they remember eating months or even years ago.
Finally, the results of the study are observational and, although they may suggest a relationship, they do not prove that one factor is causing the other.

So how many eggs should we eat per week?
Dr. Allen recommends not eating more than two or three eggs a week. It also gives some advice to lovers of these foods, such as clear eating and not the yolk, which is the main cholesterol.
Most experts agree that the key is moderation, not just with eggs, but with any food that contains cholesterol.
So even though this new study does not convince you, eating three eggs a day at breakfast may not be the best idea.
