The controversy mostly comes down to the cholesterol in eggs, about which the research is mixed. The American Heart Association recommends healthy adults consume no more than 300 milligrams of cholesterol per day. One large egg has 186 mg of cholesterol and a small one has 141 mg, according to the USDA. But in recent years, scientists have begun to question if the cholesterol in eggs is as bad for you as previously thought. For example, a 2013 meta-analysis published in journal BMJ found that eating one egg per day was not associated with increased risk of heart attack or stroke among healthy people.
