EGG

Egg yolks are high in cholesterol.

In fact, one large egg contains about 212 mg of cholesterol, which is 71% of the previously recommended intake of 300 mg per day (12).

There is now no recommended upper limit on daily cholesterol intake in the US.

However, when eggs are cooked at high temperatures, the cholesterol in them may become oxidized and produce compounds known as oxysterols (13, 14).

This is a concern for some people, as oxidized cholesterol and oxysterols in the blood have been linked to an increased risk of heart disease (15, 16).

Foods containing oxidized cholesterol and oxysterols are thought to contribute to the blood levels of these compounds (17).

That being said, the main dietary sources of oxidized cholesterol aren’t eggs. They are commercially fried foods such as fried chicken, fish and French fries (18).
