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.
Diabetic patients were the only exception. For them, high egg consumption was associated with an increased risk of heart disease and a reduced risk for hemorrhagic stroke. But there were too few diabetics in the studies to draw reliable conclusions.
The authors, writing online this month in the journal BMJ, acknowledge that self-reports regarding food consumption are not always reliable and that most of the studies had no information about the cooking methods, which could have affected the results.
