Can the elderly eat eggs? How to eat them?

　　The elderly can eat it egg ? How to eat? Some people think elderly especially coronary heart disease Patients should not eat egg yolks with high cholesterol content. As a result, some elderly people are "afraid of looking at eggs" and believe that eating egg yolks is the root cause of coronary heart disease and hyperlipidemia. In fact, this kind of "fear of eggs" mentality is unnecessary.

　　In recent years, scientists at home and abroad have discovered 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 nutritionists extract lecithin from eggs to help patients with cardiovascular disease disease The patient ate 4 to 6 tablespoons a day. After 3 months, the patient's serum cholesterol levels dropped significantly.； It is used to treat atherosclerosis and has also received unexpected effects, indicating that the lecithin in eggs has a therapeutic effect on high cholesterol.

　　Nutritionists have also proven that cholesterol combined with protein can 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 eggs can restrict and offset each other, so eating eggs will not harm healthy . The nutritional contribution of eggs to the human body can also be said to be "more merit than fault".

　　Eating eggs has more advantages than disadvantages.

　　There are many reasons why patients with atherosclerosis have high blood cholesterol. It is mainly related to unbalanced diet and lack of certain nutrients, not due to eating egg yolks. Moreover, not eating cholesterol-containing foods for a long time can also cause nutritional deficiencies. In addition, the lecithin in eggs can also release acetylcholine after digestion and absorption by the human body, and acetylcholine is nerve A chemical in cells that carries messages. The more it is in the brain, the faster it transmits information, and the more beneficial it is to improving people's memory.

　　Foreign studies have pointed out that the rhythmic supply of sufficient nutritional choline can prevent memory loss that is often suffered by elderly people over 60 years old.； At the same time, it can maintain and enhance the memory of people of all ages.

　　Although eating eggs is beneficial, it does not mean that the more you eat, the better. Considering the amount and digestive function, it is appropriate for the elderly to eat 1 to 2 eggs a day. The way they eat it can be determined according to their specific situation and preferences.
