This is not egg-citing news as most Americans find eggs a big part of their diet, but through the years they have proven controversial over the years.
"People who consume less cholesterol have a lower risk of heart disease", she adds.
The discovery, reported in the American Journal of Clinical Nutrition, suggests egg yolks maximize one's dietary protein intake, said Nicholas Burd, a University of IL professor of kinesiology and community health who led the past research.
Other animal products such as red meat, processed meat and high-fat dairy products (butter or whipped cream) also have high cholesterol content, said lead author Wenze Zhong, a postdoctoral fellow in preventive medicine at Northwestern.
Exercise, overall diet quality, and the amount and type of fat in the diet didn't change the association among dietary cholesterol. cardiovascular disease, and death risk.
Eggs have always been thought of as a healthy dietary addition and are included in many country's national dietary guidelines.
The authors of the study, from Northwestern University, said there had been conflicting information from recent studies, and US health guidelines recommend people eat eggs regularly. "We've always said you can have egg whites but you should probably limit your amount of egg yolk consumption".
But don't completely banish eggs and other cholesterol-rich foods from meals, Zhong said, because eggs and red meat are good sources of important nutrients such as essential amino acids, iron and choline.
For this study, they used data from six studies, which collectively involved almost 30,000 relatively healthy, middle-aged people with no pre-existing heart disease and followed them for a median of 17 years and up to as long as 31 years.
Scrambled, poached or over easy: No matter how you take your eggs, there's not really a sunny side to a new study that links egg consumption with a higher risk of cardiovascular disease. "And it's been very hard to tease apart the potential harmful effects of high cholesterol in eggs vs other beneficial nutrients", study author Norrina Allen, associate professor of preventive medicine at the Northwestern University Feinberg School of Medicine in IL, told Gizmodo.
In the future, Allen hopes she and others can establish a clear threshold of perfectly safe egg consumption, as well as whether certain individuals respond differently to dietary cholesterol. Take a look at how people responded to the study. For example, in the United States eggs are often eaten with bacon, sausages or burgers, so it's impossible to disentangle the effects on CVD risk of eggs from these fatty meat products. "Eat them in moderation".
Each participant was questioned on what they'd eaten for the previous year or month and the data was collected in the first visit. The participants reported on the kinds of foods they ate, and were then tracked for an average 17.5 years. "Eggs do carry a lot of it but we should not forget that it is also a rich source of protein, vitamins (Vitamin A, B, B5, B12 and D) and minerals (calcium, selenium, potassium and zinc) which are needed for body's metabolism", said Rishi Gupta, Chairman, Cardiology, Asian Institute of Medical Sciences (AIIMS), Faridabad. "But we think they represent an estimate of a person's dietary intake".
