A new study has disclosed that eating an egg daily can increase the risk of having diabetes.

Moreover, the study also said that intake of more than a couple of eggs during a week can worsen the condition in those who already have diabetes.

The study conducted by researchers at Brigham and Women’s Hospital and the Harvard Medical School in Boston studied the egg-eating habits of almost 57,000 men and women over two decades.

In their findings, published in online version of magazine Diabetes Care, the researchers said that 7.8% of the men and 1% of the women had one or more eggs on a daily basis.

Women were most susceptible, with females eating seven eggs or more during a week raising their risk levels by 77%.

Dr Michael Dr Gaziano wrote that intake of just one egg in a week carried no increased risk.

Dr. Alan Barclay, manager of human nutrition at Diabetes Australia-New South Wales, said that the study outcomes were compatible with the opinion it has provided for some years that diabetics should limit their egg intake.

Eggs are a good source of vitamins, proteins and other nutrients, but they are also rich in cholesterol, which in high amounts can block arteries and increase the risk of heart attack, stroke as well as diabetes.
