Starting the day on an egg could keep your blood pressure in check, research suggests. Scientists have shown that eggs produce proteins that mimic the action of powerful blood pressure-lowering drugs.
The finding comes a few days after a study exploded the myth that they can increase the danger of heart attacks.
It now appears that eggs may be good for the heart, lowering blood pressure in the same way as Ace inhibitors, prescription-only pills taken by millions around the world. The drugs lower blood pressure by stopping the hormone angiotensin narrowing the body's blood vessels.
The researchers, from the University of Alberta in Canada, showed that when eggs come in contact with stomach enzymes they produce a protein that acts in the same way.
Fried eggs proved particularly successful at blocking angiotensin, lab-based tests showed, the Journal of Agricultural and Food Chemistry reports. But the researchers, whose study was funded by the poultry industry, said more work was needed to show the effects outside a lab and in the human body.
Earlier this month, British researchers proclaimed that, contrary to popular perception, it is healthy to go to work on an egg. Researchers for the British Nutrition Foundation - part-funded by the poultry industry - concluded that the type of cholesterol found in eggs has minimal effect on raising heart disease risks.
