Turns out they were wrong about eggs!
Throughout the late 20th century, doctors maintained that eating more than two eggs a week could increase your cholesterol, but in recent years research experts have begun to refute this myth.
Now, a new study has found that eating more eggs is not associated at all with higher serum cholesterol in adolescents, regardless whether they do any physical activity or not.
The study led by researchers at the University of Granada, analysed the link between egg intake in adolescents and the main risk factors for developing cardiovascular diseases, such as lipid profile, excess body fat, insulin resistance and high blood pressure.
As Alberto Soriano Maldonado, primary author of the study, explains to SINC: “Health professionals traditionally insisted that eating eggs increased cholesterol levels, so in recent decades there has been a tendency to restrict intake”
However, the research suggests that increased serum cholesterol is more affected by intake of saturated fats and trans fats – present in red meat, industrial baked goods, etc. – than by the amount of cholesterol in the diet.
The results of this research demonstrated that eating larger amounts of egg is neither linked to higher serum cholesterol nor to worse cardiovascular health in adolescents, regardless of their levels of physical activity.
“The conclusions, published in the journal Nutrición Hospitalaria, confirm recent studies in healthy adults that suggest that an intake of up to seven eggs a week is not associated with an increased risk of developing cardiovascular diseases,” notes Soriano.
As a result, the authors suggest reviewing dietary recommendations with respect to eggs, although they add that it would be useful to conduct similar research on a sample group with higher egg intake.
“Egg is a cheap food that is rich in very high-quality proteins, minerals, folates and B vitamins. Thus it can provide a large quantity of nutrients necessary for optimum development in adolescents,” according to the researcher.
