The old saying goes that an apple a day keeps the doctor away. But it seems that the same could hold true for an egg a day.
Latest research by scientists in the US found that eating one egg per day reduces the risk of having a stroke by 12 per cent.
Researchers also found that, while eggs have previously been linked to cholesterol fears, eating an egg a day did not increase the risk of coronary heart disease, which is the main cause of death across the globe.
Scientists looked at a host of studies which were published between 1982 and 2015. Each study involved more than 275,000 people.
They looked at whether eating eggs reduced or increased the risk of heart disease or stroke.
Dr Dominik Alexander from the US’s EpidStat Institute, led the research team.
Outlining the main findings, he said: “Eggs do have many positive nutritional attributes, including antioxidants, which have been shown to reduce oxidative stress and inflammation.
“They are also an excellent source of protein, which has been related to lower blood pressure.”
Every large egg contains a host of beneficial ingredients, including protein, antioxidants, lutein and zeaxanthin, as well as vitamins E, D and A. Lutein and zeaxanthin are both linked to eye health.
Vitamin E has already been found in previous studies to have properties which can help reduce the risk of heart attacks in people suffering from heart disease, while lutein is reported to help prevent clogging of the arteries.
This latest study follows new Dietary Guidelines for Americans, which includes regularly eating eggs. People are advised to consider eggs as part of their diet when making choices over which proteins to eat.
Doctor Tia Rains from the Egg Nutrition Centre said the new review backed up previous research showing there was no link between heart disease and eggs. More than that, she said, it now showed that there was potentially a positive effect of eating eggs through cutting the risk of stroke.
Every year, almost 130,000 people die as a result of stroke in America, where it is the leading cause of death. Combined with cardiovascular disease, around 800,000 people in the US lose their lives as a result.
Stroke can also cause long-term disability, including speech problems and loss of independence so the new research could have far-reaching benefits for public health in the US and beyond.
