Eggs are high in dietary cholesterol, a contributor to heart disease, and can lead to food poisoning if not cooked properly. A review published in a 2010 edition of the “Canadian Journal of Cardiology” reported that people at risk for heart disease should limit cholesterol intake, especially from egg yolks, which contain about 184 milligrams of cholesterol per yolk. The same review encouraged limiting dietary cholesterol to less than 200 milligrams per day to reduce heart disease risk. Medline Plus recommends limiting egg consumption to four eggs or fewer per week. Salmonella bacteria are often present in eggs, and can cause illness if the eggs are not thoroughly cooked. Hard-boiled and scrambled eggs are safer than eggs with runny yolks.
