Eggs include fat and cholesterol, which can be bad for your heart and cause diabetes, prostate and colorectal cancers, as well as other diseases.
Heart disease
Eggs contain about 60% calories from fat, most of which is saturated fat. A typical-sized egg has 200 milligrams of cholesterol, which is a lot for a food. That is more than twice as much as a Big Mac. Heart disease is exacerbated by fat and cholesterol.
According to a study from 2021, eating an additional half an egg per day was linked to an increase in fatalities from cancer, heart disease, and other causes. Mortality risk rose by up to 24% for every 300 mg of dietary cholesterol consumed each day. According to a study that was published in JAMA, eating 300 milligrams of dietary cholesterol per day raised the risk of cardiovascular disease and mortality by 17% and 18%, respectively. When it comes to eggs, there was a 6% and 8% higher risk with each half egg, respectively. According to a study published in the Canadian Journal of Cardiology, people who consume the most eggs are 19% more likely to experience cardiovascular issues.
Research that was supported by the industry downplayed the impact of egg consumption on cholesterol levels. All studies evaluating the impact of eggs on blood cholesterol levels published between 1950 and March 2019 were examined by the Physicians Committee for a review article that appeared in the American Journal of Lifestyle Medicine. The review also looked at funding sources and their impact on study results. Research from before 1970 revealed no industry influence on the study of cholesterol. Over time, the proportion of studies supported by industry rose from 0% in the 1950s to 60% in the period from 2010 to 2019.Regardless of the funding source, more than 85% of research investigations revealed that eggs have negative impacts on blood cholesterol. However, compared to 13% of non-industry-sponsored studies, 49% of publications financed by the industry presented conclusions that were at odds with the actual study results.
According to a study that was published in the British Journal of Nutrition, eating one or more eggs per day may increase the risk of diabetes by 60%. Using data from the China Health and Nutrition Survey, researchers compared the blood glucose levels of more than 8,000 people and their egg consumption. Those who regularly ate the most eggs had a higher chance of developing diabetes than those who did not.
These findings corroborate earlier research. According to an analysis of 14 research in the journal Atherosclerosis, people who eat the most eggs had a 68% higher chance of developing diabetes. Similar findings were reported in another review: consuming three or more eggs per week is associated with a 39% increased risk of diabetes.
Two studies published in the American Journal of Epidemiology indicate that eating eggs raises the risk of gestational diabetes as well.
Cancer
Additionally, eating eggs has been linked to a higher risk of getting cancers such colon, rectal, and prostate.
