Egg a day linked to a lower risk of heart disease



"Eggs increase the risk of vascular disease," said Spence, who was not involved in the study, by e-mail. For example, egg yolks contain phosphatidylcholine, a chemical that can contribute to clog arteries, he said.

Eggs are a primary source of dietary cholesterol, but they also contain high-quality lean protein and many vitamins, the study team notes. the Heart newspaper. Previous research on the link between eggs and heart disease has offered inconsistent results, some point to a protective effect and others suggest that eggs can make people more likely to have a heart attack or stroke.

Part of the problem revolves around cholesterol.

Eggs can contain about 200 milligrams of cholesterol, and scientists used to think that eating eggs would lead to higher levels of blood cholesterol, Djousse said.

Some more recent research, however, suggests that the eggs could block the liver producing low-density lipoprotein (LDL), the type of bad cholesterol that can accumulate in blood vessels and cause blood clots and heart attacks, and increase the production of high density lipoprotein (HDL), the good kind that is needed for healthy health blood flow.

The study was not a controlled experiment designed to test whether eggs could affect the risk of developing cardiovascular disease or die from it. The study's lead authors, Canqing Yu and Liming Li of the Health Sciences Center at Peking University in Beijing, did not respond to a request for comment.

Another limitation is that the results in China may not apply in other parts of the world. The study participants generally had a healthy weight and most of them did not have high blood pressure or a family history of heart disease.

In the USA UU., Where most adults are overweight or obese and eat a Western diet loaded with meat and potatoes and light on fruits and vegetables: the connection between eggs and heart disease could be quite different.

For optimal cardiac health, the AHA recommends Diet Diets to Stop Hypertension (DASH) or a Mediterranean-style diet. Both diets emphasize unsaturated vegetable oils, nuts, fruits, vegetables, low-fat dairy products, whole grains, fish and poultry, and both limit red meat, as well as foods and beverages with a high content of added sugars and salt.
