Can the elderly eat egg yolks?

　　Can the elderly eat egg yolks? many people think elderly especially coronary heart disease Patients should not eat egg yolks with high cholesterol content. They believe that eating egg yolks is the root cause of coronary heart disease and hyperlipidemia. Is this true? In fact, this kind of "fear of eggs" mentality is unnecessary.

　　Scientists have discovered in recent studies that in addition to cholesterol, egg yolk is also rich in lecithin. Lecithin is a strong emulsifier that can make cholesterol and fat particles smaller and keep them in a suspended state, which helps lipids penetrate the blood vessel walls and be used by tissues, thereby reducing cholesterol in the blood. American nutritionist from egg Extract lecithin from Chinese medicine to improve cardiovascular health disease The patients consumed it every day. After 3 months, the patient’s serum cholesterol levels dropped significantly.； Used to treat atherosclerosis, it also has unexpected effects. This shows that the lecithin in eggs has a therapeutic effect on high cholesterol.

　　Cholesterol combines with protein to form a "lipoprotein." This kind of "lipoprotein" is divided into very low-density lipoprotein, low-density lipoprotein and high-density lipoprotein according to its particle size. The first two can be deposited on the blood vessel wall, while the latter has the effect of removing cholesterol from the blood vessel wall. In this way, the ingredients in the egg can restrict and cancel each other out. The nutritional contribution of eggs to the human body can be said to be "more merit than fault".

　　There are many reasons for high blood cholesterol in patients with atherosclerosis. They are mainly related to unbalanced diet and lack of certain nutrients. They are not caused by eating egg yolks. Moreover, not eating cholesterol-containing foods for a long time will also cause nutritional deficiencies.

　　In addition, the lecithin in eggs can also release acetylcholine after digestion and absorption by the human body. Acetylcholine is nerve It is a chemical substance that transmits information in cells. The more it is in the brain, the more beneficial it is to improving memory, and can avoid memory loss that is often suffered by people over 60 years old. At the same time, it can maintain and enhance memory for people of all ages.

　　Although eating eggs is beneficial, it is not that the more the better. Considering the amount required and digestive function, it is appropriate for the elderly to eat one egg a day. Text/Zhao Xin
