Despite cholesterol, an egg a day won’t give you a heart attack, so says Harvard researcher

eggPeople with high cholesterol are more likely to have heart attacks so eating food that is high in cholesterol raises the risk of heart attack too? Not so says a new study, adding evidence to the debate over the true role of cholesterol and heart disease. (More on the debate here.)

More here from the NYTimes:

Egg yolks are high in cholesterol, but a new analysis adds to the evidence that they are not the dietary sin we once thought they were. The review suggests that for most people, eating one egg a day is not bad for the heart.

Researchers reviewed eight prospective studies including 263,938 subjects and pooled the data for analysis. They found no evidence that eating up to an egg a day increased the risk of heart disease or stroke. The results were the same for men and women and in all age ranges

More here from the BMJ study:

What is already known on this topic

  • Cardiovascular disease affects millions of people in both developed and developing countries

  • As a major source of dietary cholesterol, eggs have been investigated by several epidemiologic studies in relation to risk of coronary heart disease and stroke

  • However, whether egg consumption increases the future risk of coronary heart disease and stroke remains unclear

What this study adds

  • Consumption of up to one egg per day was not associated with increased risk of coronary heart disease or stroke

  • Subgroup analysis suggested that consumption of up to one egg per day was associated with a significantly elevated risk of coronary heart disease in diabetic populations, and a reduced risk of hemorrhagic stroke
