Go ahead and scramble those eggs, yolk and all—there’s new evidence that it may lower your risk of heart disease.
Two new studies from the University of Connecticut recently presented
at the Experimental Biology conference found that eating eggs actually
improved cholesterol levels and reduced disease-producing inflammation
in the body.
In one study, researchers asked participants following a
carbohydrate-restricted diet to eat three whole eggs per day while
another group ate an equivalent amount of egg substitute. After 12
weeks, the whole egg group experienced increases in levels of “good” HDL
cholesterol, from 50 mg/dL to 59 mg/dL. (Doctors say men should aim for
HDL levels over 40 mg/dL.) Their LDL (“bad”) cholesterol levels didn’t
change at all.
How? Lecithin, a substance found in the egg yolk, might increase HDL
cholesterol. “Lecithin helps remove cholesterol from tissue and
transport it to the liver, so it doesn’t build up in blood vessels,”
says study coauthor Maria Luz Fernandez, Ph.D., a nutrition professor at
the University of Connecticut.
In a second similar study, people on a carbohydrate-restricted diet
with metabolic disease who ate three eggs for 12 weeks showed a decrease
in inflammatory markers in the body, suggesting that their risk for
heart disease dropped. Lutein, an antioxidant caroteinoid found in the
yolk, likely helped reduce this inflammation, says Fernandez. (Sick of

Though both studies were done on people on restricted-carbohydrate
diets, Fernandez says that you could expect similar benefits by making
eggs part of a regular healthy diet.
“People are concerned that eating eggs causes heart disease but they
really do the opposite,” says Fernandez. Whip up one of these Healthy Egg Recipes for breakfast tomorrow!
