How beneficial are eggs for the heart?

Health conscious lay multiple eggs daily. Although everyone knows that egg yolk contains enough cholesterol. As a result, eating extra eggs can increase cholesterol levels. Many believe that eating too many eggs is bad for heart health.

Some studies show that eggs are very beneficial for health. A study published in the journal Heart in 2018 looked at nearly half a million adults in China. Studies have shown that people who eat at least one egg per day have a significantly lower risk of heart disease and stroke than others.

The main objective of the researchers was to know how beneficial the consumption of eggs is for cardiovascular health. Lang Pan, a professor in the Department of Epidemiology and Biostatistics at Peking University and study author, said lipid metabolites play a key role in the association between egg consumption and cardiovascular disease risk. Pan and his team selected 4,778 participants from the China Kaduri Biobank, of whom 3,411 had cardiovascular disease and 1,377 were healthy. They used a technique called targeted nuclear magnetic resonance to measure 225 metabolites in plasma samples taken from participants' blood. Of these metabolites, they identified 24, which were associated with self-reported levels of egg consumption. It found that people who ate moderate amounts of eggs had higher blood levels of apolipoprotein A1, a protein called a building block of high-density lipoprotein (HDL). Also known as good lipoproteins.

Their blood had larger HDL molecules, which help clear cholesterol from blood vessels. As a result, it protects against blockages that can lead to heart attacks and strokes. 'Further research is needed to verify the functional role that lipid metabolites play in the association between egg consumption and cardiovascular disease risk.'
