Researchers belonging to the Northwestern University Feinberg School of Medicine in Chicago along with several other institutes analyzed the data from six cohort studies including a total of 29,615 people. Of all the participants, about 45 percent were men and 31 were black.
The study compared all the people’s eating patterns at the baseline. Remember that the average age of these participants was 52 years. The findings of this study are present in JAMA.
An Increased Risk of Heart Diseases and Fatalities
Dr Allen, the lead researcher of this study says that the studies that found no associations between the consumption of eggs and the increased risk of cardiovascular diseases had a problem.
The problem is that they used lesser diverse samples and much shorter follow-ups. Moreover, these studies were also not able to adjust for all other items included in their diet.
The present study is different because it showed that if two different people ate the exact same meals with the only difference of eggs, the effect caused by these eggs could be measured in terms of the risk of heart disease.
The dietary data for this newer study was compiled from different interviews and questionnaires that took place in a single visit. They provided the researchers with details about what all the people ate in the previous month or year.
Almost 5400 cardiovascular emergencies and over 6132 deaths occurred during the follow-up period of the study. The examples of cardiovascular events include heart failure, stroke, and various diagnoses of heart diseases.
The scientists discovered that for every additional intake of about 300 mg of cholesterol, a 17 percent increase in the risk of cardiovascular events was seen and an 18 percent increase in the death risk
The research team also found out the absolute risk differences for the results they collected. These differences were found to be about 3.24 and 4.43, respectively.
In simpler words, for every thousand participants present in the study, there were 32 other diagnoses of cardiovascular problems and almost 4 deaths for every extra 300 mg consumption of cholesterol on a daily basis.
The analysis also revealed that for every additional half of egg eaten every day, there was a 6 percent increase in the risk of cardiovascular disease and an 8 percent increase in the risk of deaths.
The quality of the diet, the amount and type of fat they consumed, and the overall amount of exercise they performed had no effect on any of these associations.
The results of this study must be considered in the development of dietary updates and guidelines.
The study authors have said how this study is prospective and is unable to provide a link between the cause and the effect. It can only suggest these links.
However, the take-home message is that the U.S. diet which is rich in lots of eggs and meals is closely linked with poor cardiovascular health. Therefore, it must be included in the dietary guidelines that the cholesterol intake must not go beyond 300 mg per day.
