Is "Eggs are extremely bad for cholesterol and should be avoided" true?
Eggs spent decades as nutritional public enemy number one, with doctors' office posters counting cholesterol milligrams per yolk like a countdown to a heart attack. Skip the eggs, save your arteries: that was the entire pitch, repeated without much pushback. Years of follow-up research kept walking the warning back, egg by egg, until the American Heart Association dropped its specific limit in 2002. For most people, even a dozen eggs a week barely registers on cholesterol or cardiovascular risk.

Eggs are extremely bad for cholesterol and should be avoided
What we know now
Studies show eggs have minimal impact on blood cholesterol for most people and provide valuable nutrients. The American Heart Association (AHA) dropped its specific recommendation to limit eggs in 2002. Since then, multiple studies have shown that eating eggs—even up to 12 per week—does not significantly impact cholesterol levels or increase cardiovascular risk in most people, including those at higher risk for heart disease.
Was "Eggs are extremely bad for cholesterol and should be avoided" taught in school?
Yes — and not as a joke question on a quiz. This health claim showed up in textbooks, worksheets, and classroom posters through the 1980s, which is why so many people still remember it as settled fact long after the science moved on.

When was this understanding updated?
The evidence had largely shifted by around 2002. Schools don't flip overnight, though — plenty of classrooms kept teaching the older version for years after researchers had already moved on.
