An egg a day may keep the doctor away, study claims

For decades, experts warned that eating eggs raises levels of unhealthy cholesterol. But a study May 22 said an egg a day may actually reduce the risk of heart disease and stroke.

While outside experts cautioned against reading too much into the study, its authors claimed that Chinese adults who ate an egg every day had a lower risk of cardiovascular disease (CVD).

Studying half-a-million healthy adults aged 30-79 over almost nine years, researchers concluded that "compared with non-consumers, daily egg consumption was associated with lower risk of CVD."

Risk of hemorrhagic stroke was 26 percent lower among egg-eaters, the Chinese-British research team reported in the journal Heart.And daily egg consumption was associated with an 18-percent lower risk of death from CVD, and a 28-percent lower risk for death from hemorrhagic stroke.

CVD, a group of disorders of the heart and blood vessels, is the leading cause of death and disability worldwide, including in China.

According to the World Health Organization, about 17.7 million people die of CVDs each year, almost a third of all deaths worldwide. Eighty percent of CVD deaths are caused by heart attacks and strokes.

Smoking, not exercising enough, and eating an unhealthy diet high in salt and low in fresh fruit and vegetables, increase the risk.

Eggs are rich in dietary cholesterol, long linked to a higher CVD risk, but also contain crucial protein and vitamins.

In the study group, 13 percent reported daily egg consumption, while nine percent said they never or hardly ever ate them.            By the end of the study period, almost 84,000 cases of CVD and 10,000 CVD deaths were recorded, and compared among the different egg-intake groups.

"The present study finds that there is an association between moderate level of egg consumption (up to 1 egg per day) and a lower cardiac event rate," the authors concluded. But experts not involved in the study, said the results fail to prove that eating eggs actively lowers CVD risk.
