Are eggs good for you? The long-standing dairy discussion may have more answers, and it looks like bad news for egg lovers.

A new study suggests people with a higher consumption of eggs or cholesterol may be at a higher risk for cardiovascular disease and early death.

Eggs are a "major source of dietary cholesterol," the study authors say, and much debate has been had in recent years over guidelines for Americans and cholesterol consumption.

In their analysis, researchers found a 17 percent increased risk of cardiovascular disease and 18 percent increased risk of premature death associated with each additional 300 milligrams of dietary cholesterol had each day.

Each additional half an egg eaten each day, or three to four eggs per week was associated with a 6 percent higher risk of cardiovascular disease and an 8 percent higher risk of early death.

Americans get an average of 300 milligrams of dietary cholesterol per day and eat an average of about half an egg daily, the study authors say.

"The take-home message is really about cholesterol, which happens to be high in eggs and specifically yolks," study co-author Norrina Allen, a Northwestern University medicine professor, said in a statement. "As part of a healthy diet, people need to consume lower amounts of cholesterol. People who consume less cholesterol have a lower risk of heart disease."

The research, published Friday in the Journal of the American Medical Association, drew on data from six studies in the Lifetime Risk Pooling Project, which included over 29,000 people followed for a median of 17.5 years of follow-up. In that follow-up time, there were 5,400 incidents of cardiovascular disease, both fatal and nonfatal.

The study authors say past research wasn't conclusive on the heightened risks of cardiovascular disease associated with eggs, and the sample data some used weren't as diverse.

While Allen isn't suggesting people stop eating eggs altogether, they should eat them in moderation, she said in a statement.

The researchers also say U.S. dietary guideline recommendations may need to be re-evaluated given that there is not a recommended daily limit for dietary cholesterol.

The average large egg, including its yolk, is about 50 grams and contains approximately 186 milligrams of cholesterol, the authors say. 

While the study may raise some concerns for egg eaters, there are limitations to the research.

The study only showed an association, not a cause-and-effect relationship between eating eggs or cholesterol and their health risks. Researchers also couldn't account for longer-term changes to people's diets in the samples.
