A new study has brought some bad news for egg lovers. Researchers from Northwestern University found that eating eggs leads to high cholesterol and greater risk of heart disease and death. It has to do with the cholesterol found in the yolk.
The researchers found that eating just three to four eggs per week was tied to a 6 percent higher risk of heart disease, and an 8 percent risk of dying from any cause.
Norina Allen, PHD, one of the authors of the study stated, ““The take-home message is really about cholesterol, which happens to be high in eggs and specifically yolks. As part of a healthy diet, people need to consume lower amounts of cholesterol. People who consume less cholesterol have a lower risk of heart disease.”
The researchers analyzed 30,000 U.S. adults over three decades. But this not something new. All foods from animal source contain cholesterol.
How much cholesterol does a single egg have?
One medium egg has around 186 mg of cholesterol. People with heart disease are advised to limit themselves to 200mg of cholesterol per day. So should they have to be vegan for the rest of the day.
This controversy over eating eggs has been going on for a long time. First they said eggs are a rich source of protein and hence should be eaten daily. Well, lots of other animals are not eating eggs and still getting their proteins. So then came another argument that eating eggs increases good cholesterol. This was a master-stroke and it was published all over the internet. But studies done by Lipid Research Laboratory observed that consumption of 2 eggs per day resulted in increase of plasma cholesterol concentration by 11% (p < 0.05) as a result of increased plasma low-density lipoprotein (LDL) cholesterol levels. The study concluded that eggs consumption, in addition to its hypercholesterolemic effect, increases plasma and LDL oxidizability, a phenomenon which was shown to enhance the progression of atherosclerosis.
The controversy still rages. But the best option is plant based diet and raw vegetables.
