Patients with coronary heart disease can eat eggs; it is recommended to eat one each morning to balance the nutritional needs of the body. However, it is crucial not to consume them excessively, as eggs, especially the yolks, contain cholesterol and a high amount of lipids. One of the primary causes of coronary heart disease is the accumulation of lipids due to atherosclerosis. Therefore, to prevent an increase in cholesterol levels, excessive consumption should be avoided, as it can lead to higher cholesterol levels if the body cannot digest it properly, exacerbating the condition and causing harm to the body. Thus, it's important to control and moderate consumption.
