Everyone knows that the egg is rich in nutrients, it can give birth to life, so it naturally contains a variety of nutrients necessary for life. Because the egg contains a variety of essential amino acids, and human protein composition is similar, so it is an ideal natural tonic. However, in recent years, more and more people regard eggs as a cause of high blood cholesterol, hypertension, atherosclerosis, coronary heart disease and other diseases of the culprit, the reason is that it contains high cholesterol, so that the original patients with the above diseases feel that, and then eat eggs, it is simply "fuel on the fire". So a lot of people began to stay away from eggs, or only eat egg whites to throw away the yolk.

However, this may be a misunderstanding of eggs. In fact, in recent years, many nutritionists have begun to recommend eggs to combat atherosclerosis. Researchers at Kansas State University in the United States, through a test that strictly mimics human physiology, found that lecithin can interfere with cholesterol absorption, significantly reducing the amount of cholesterol absorbed by the small intestine. So, the United States nutritionists extracted lecithin from eggs, 4 to 6 tablespoons a day to cardiovascular patients, 3 months later, the patient's serum cholesterol significantly reduced. This research has been the attention of the medical profession, the countries successively used this method for clinical use, are more satisfactory results.

For example, Boston internist Dr. Berman for more than 400 overweight police officers formulated a diet recipe, which must be eaten every day on the eggs. Years later, none of the 400 police officers had been found to have elevated blood cholesterol levels, nor had there been a single case of heart disease. This shows that many of our perceptions of eggs are misconceptions, eating eggs not only does not make us cholesterol rise, but on the contrary, the cardiovascular system has a special protective effect.

Many people with high blood cholesterol are particularly worried about their high cholesterol levels, but in fact, high cholesterol itself does not cause heart disease, and the probability of heart disease for people with high blood cholesterol is the same as for those with lower levels. The crux of the problem lies in the ratio between good cholesterol (HDL) and bad cholesterol (LDL) in the body. The cholesterol in eggs raises the level of good cholesterol and lowers the level of bad cholesterol.

The fat in eggs is high in Omega-3 fatty acids, an unsaturated fatty acid that has been medically proven to raise HDL and lower LDL. And most of the fat in eggs is in the yolk, so it's not advisable to throw out the yolk for fear of raising cholesterol.

In addition, triglycerides are actually more competent as indicators of coronary artery disease than cholesterol. High triglyceride levels in the blood will lead to atherosclerosis and increase the risk of heart disease and stroke, while eggs help to lower triglyceride levels in the blood. So it's essential to eat some eggs properly, and even more so for people with high blood cholesterol.

And, for all of us, especially those with high blood cholesterol, lecithin is a much-needed substance that is a powerful emulsifier. It can make cholesterol and fat particles become extremely fine, emulsify into fine particles suspended in the blood without being deposited on the blood vessel wall, and can pass through the blood vessel wall smoothly to be utilized by the cells, thus reducing the cholesterol in the blood. The yolk of the egg is rich in lecithin, which is more abundant and of better quality than that contained in beans. So there is absolutely no reason to throw away egg yolks as garbage.

It's just that, while eggs can help lower cholesterol, it's not true that the more you eat, the better. So, how many eggs is the right amount per person per day?

From a nutritional point of view, in order to ensure a balanced diet, to meet the needs of the body, but not over-nutrition, in general, the elderly to eat 1 egg per day is appropriate. Young people, eat 2 eggs a day is no harm, but more than two is a little too much. Generally speaking, it would be more appropriate to eat one egg per day.

In terms of cooking, in order to ensure the nutrition, choose to boil and steam better. The human body can absorb up to 100% of boiled eggs, 97% of scrambled eggs and 81.1% of fried eggs. Obviously, although fried eggs taste better, but not easy to digest. In addition, hard-boiled eggs should be boiled for 5 minutes after the water is boiled, scrambled eggs should be tender rather than old, and fried eggs should not be too vigorous and high temperature. Therefore, I still recommend that patients with high blood cholesterol eat more boiled eggs in plain water or steamed egg custard, tomato scrambled eggs, etc., try to avoid frying with too much oil.
