Myth: It’s best to avoid eggs — or at least the yolks.
The argument: Egg yolks contain lots of cholesterol. So, logically, eating cholesterol leads to high cholesterol. Right?
The reality: Most of the cholesterol in the body is made by the liver, not delivered through diet. And while diet does matter, research has found that cholesterol levels have more to do with the fat you eat, namely saturated and trans fats, than cholesterol. Eggs contain healthy nutrients, including vitamins A and D, as well as protein. Long-term population studies show that eating an egg a day hasn’t been linked to higher rates of heart attack or stroke. But beware the side of bacon and cheese, which can raise your risk.
