Eating steamed eggs at night will make you fat, because metabolism is slow at night, digestion will slow down, and it will also cause a certain burden on the stomach, so it is easy to cause obesity. According to the analysis, every100g of eggs contains14.7g of protein, mainly ovalbumin and ovalbumin, and contains 8 kinds of amino acids necessary for human body, which is very similar to the composition of human protein. The absorption rate of protein in eggs can reach 98%. Every100g of egg contains11~15g of fat, which is mainly concentrated in yolk and easily digested and absorbed by human body. Egg yolk is rich in lecithin, sterol, egg yolk, calcium, phosphorus, iron, vitamin A, vitamin D and B vitamins. These ingredients have great benefits for improving the function of the nervous system, so eggs are better brain food.

Egg yolk contains more cholesterol, which can be as high as 100 mg per100 g. Therefore, many people, especially the elderly, are cautious about eating eggs, fearing that eating eggs will lead to increased cholesterol and atherosclerosis. In recent years, scientists have found that eggs are rich in lecithin despite their high cholesterol content. When lecithin enters the blood, it will make the particles of cholesterol and fat smaller and remain suspended, thus preventing the deposition of cholesterol and fat on the blood vessel wall. Therefore, scientists believe that for the elderly with normal cholesterol, eating 2 eggs a day will increase the cholesterol in 100 ml of blood by up to 2 mg and will not cause arteriosclerosis. But you shouldn't eat too much. Eating too much is not conducive to gastrointestinal digestion, causing waste and increasing the burden on liver and kidney. It is advisable for everyone to eat 1 ~ 2 eggs every day, which is beneficial to digestion and absorption and can meet the needs of the body.

Eggs are an ideal natural food for human beings, and we should also pay attention to science in eating. For the elderly, it is best to boil eggs, lie eggs, steam eggs and stir eggs, because frying, frying and frying are delicious, but they are difficult to digest. If eggs are processed into salted eggs, their calcium content will increase obviously, from 55 mg per 100 g to 5 12 mg, which is about 10 times that of fresh eggs. It is especially suitable for middle-aged and elderly people with osteoporosis. Also need to be reminded, never eat raw eggs. Some people think that eating raw eggs is nutritious, which is unscientific.

As long as you control the time of eating and don't eat too much two hours before going to bed, there is actually no problem.
