Eating 3-6 Eggs/Week Lowers Risk Of Cardiovascular Disease

Eating 3-6 Eggs/Week Lowers Risk Of Cardiovascular Disease from Natural Blaze

Eggs have been acknowledged as a good source of high-quality proteins and contain bioactive components beneficial for health, while they are also loaded with abundant cholesterol in the yolks, making the public hesitant about consuming whole eggs. Up to now, most studies exploring the association of egg consumption with incident CVD or total death were conducted in high-income countries and findings were inconsistent across populations and CVD subtypes. Accordingly, no consensus has been reached on the recommendation of egg consumption around the world.

The current study conducted by Xia and her colleagues from Fuwai Hospital, Chinese Academy of Medical Sciences suggested that there were U-shaped relationships between egg consumption and the risks of incident CVD and total death among general Chinese, and those consumed 3-6 eggs/week was at the lowest risk. More specifically, consumption of <1 egg/week was associated with 22% higher risk for incident CVD and 29% higher risk for total death; on the other hand, consumption of >=10 eggs/week was associated with 39% and 13% higher risk for incident CVD and total death, respectively.

In addition, researchers pointed out that the influence of egg consumption seemed to be different across CVD subtypes. Individuals had higher consumption of eggs was more likely to have increased risk of coronary heart disease (CHD) and ischemic stroke, while the elevated risk of hemorrhagic stroke was only found among those with lower consumption.

The current study was conducted based on the project of Prediction for Atherosclerotic Cardiovascular Disease Risk in China (China-PAR), which was established to estimate the epidemic of CVD and identify the related risk factors in general Chinese population. A total of 102136 participants from 15 provinces across China were included, who were all free of CVD, cancer or end-stage renal diseases at baseline. During up to 17 years of follow-up, 4848 cases of incident CVD (including 1273 CHD and 2919 stroke), and 5511 total death were identified, with over 90% follow-up rate.
