Greetings to the respected researcher

Undoubtedly, the egg, especially the yolk, is rich in useful nutrients for the body. In relation to your question, it is not possible to clearly state whether it is useful or harmful in relation to ischemic heart disease, because it depends on the amount of cholesterol in the yolk and the condition of the person, including his physical condition, age and daily activities. If the person is very active, the threshold of The exposure to this disease will be higher and its risks will be less.

Since eggs are a major source of dietary cholesterol, with one large egg containing almost 210 mg of cholesterol, the public has been recommended to limit egg consumption unless the intake of other foods high in cholesterol is restricted. However, eggs are also an inexpensive and low calorie source of many other nutrients, including minerals, proteins, and unsaturated fatty acids, which could lower the risk of cardiovascular disease. Additionally, in populations following a carbohydrate restricted diet, dietary cholesterol from eggs could increase plasma concentrations of high density lipoprotein (HDL) cholesterol, which has been suggested to protect against vascular disease. Therefore, some organizations have recommended that reducing egg intake might not be important for healthy people with normal levels of cholesterol in the blood. Food based dietary guidelines from countries including Nepal, Thailand, and South Africa recommend consuming eggs every day or regularly as part of a healthy diet.

ns Higher consumption of eggs (up to one egg per day) is not associated with increased risk of coronary heart disease or stroke. The increased risk of coronary heart disease among diabetic patients and reduced risk of hemorrhagic stroke associated with higher egg consumption analyses
