Cardiovascular disease is a group of diseases that harm the heart or blood vessels.
It includes coronary heart disease, stroke, heart failure, high blood pressure, heart attack, abnormal heart rhythm, congenital heart disease, peripheral artery disease and so on.
The diagnosis of cardiovascular disease does not have a long history. According to NIH, we only know this disease for 60 years, but the disease is responsible for the major death of Americans every year.
Since the time it was detected, cardiovascular disease has been battled by lots of treatments and therapies.
Many therapies are related to lifestyle changes, which include quitting smoking, controlling blood pressure, exercising regularly and having a healthy diet.
It is not hard to have a heart-healthy diet. Scientists have suggested people eat more green vegetables, fruits, whole grains, low-fat or fat-free dairy foods, fatty fish with omega 3, beans and nuts.
But for eggs, the advice has been conflicting. Some researchers claim that eggs are not healthy to the heart due to the high cholesterol in the egg yolk, while others suggest that it is fine to eat eggs.
In a recent study from University of Sydney, researchers try to clear up the conflicting dietary advice around egg eating.
They recruited two groups of people in their study. All people were diagnosed with type 2 diabetes or pre-diabetes.
One group ate 12 eggs every week, while the other group ate less than two eggs every week.
The researchers did not find any difference on cardiovascular disease between the high-egg diet group and the low-egg diet group.
These participants were then taking part in a weight loss program for another 3 months, and they continued their high- or low- egg diet.
After that, the researchers did some follow-up research for an additional 6 months, and the participants were still on their egg diet.
In both weight loss program and the follow-up period, no difference on cardiovascular disease was found between the high-egg diet group and the low-egg diet group.
In addition, the two-group lost similar amount of body weight, regardless of how many eggs they ate every week.
The researchers said, “Despite differing advice around safe levels of egg consumption for people with pre-diabetes and type 2 diabetes, our research indicates people do not need to hold back from eating eggs if this is part of a healthy diet”.
“While eggs themselves are high in dietary cholesterol — and people with type 2 diabetes tend to have higher levels of the ‘bad’ low density lipoprotein (LDL) cholesterol — this study supports existing research that shows consumption of eggs has little effect on the levels of cholesterol in the blood of the people eating them.”
