But because eggs taste good, eating a lot every day may pose some threats to the body. First of all, the content of protein in eggs is high, which will greatly increase the metabolic burden of the kidney and aggravate the condition for friends with renal insufficiency or chronic diseases complicated with nephropathy; In addition, egg yolk contains high cholesterol, which may have some adverse effects on some people who need to strictly control the intake of fat and cholesterol; The calcium content in eggs is not low, so it is suitable as an auxiliary calcium supplement food. However, if you eat a lot of eggs, high calcium intake may increase the blood calcium concentration, increase the body's excretion of calcium, and easily lead to calcium deficiency; Eggs have a good feeling of fullness, and it is easier to ignore the intake of other foods when eating too much, resulting in nutritional imbalance.
Some friends think it is not good to eat eggs every day because the cholesterol content of yolk is too high. If there are three high patients, they will generally choose not to eat or rarely eat eggs. It's really not necessary. The effect of cholesterol in eggs on your health is not what we thought. High cholesterol does affect health, but the cholesterol in our body is not only taken from outside food. On the contrary, the cholesterol obtained from external food has little effect on our total cholesterol, accounting for only about 20% of the total cholesterol, and the absorption will continue to decline with the increase of intake. For example, 1 egg yolk contains 280mg of cholesterol, and our final absorption is estimated to be 30mg.
But why do we suffer from hypercholesterolemia? Do you dare to say that it is not caused by eating habits?
It is indeed closely related to eating habits, but it is not caused by eating high-cholesterol foods, such as long-term overeating, eating high-oil and high-fat foods, and eating midnight snacks, especially puffed snacks, processed foods, fried foods, desserts and other foods. Hypercholesterolemia depends more on "endogenous cholesterol" synthesized and secreted by ourselves. Endogenous cholesterol accounts for more than 80% of total cholesterol, which is mainly synthesized by the liver. It is related to life, eating habits, liver health and genetic factors. In addition, if there are more "low density lipoprotein" in the blood, it will also cause hypercholesterolemia. Low-density lipoprotein (LDL) is called "bad cholesterol", its function is to make the cholesterol in the blood circulate indefinitely, which is easy to induce hypercholesterolemia, and "hydrogenated oil" in processed foods is the easiest to carry LDL, such as potato chips, ham, sausage, cakes, instant drinks, fried foods and so on.
Can we eat the cholesterol in that egg without restraint? Of course, eating too much of any ingredient may be harmful to our health. Even if the cholesterol in eggs is not so threatening to us, we are not suitable to eat too much. In short, don't eat too much or not. Cholesterol in eggs is also easier to be converted into good cholesterol, that is, "high density lipoprotein". High density lipoprotein can accelerate the metabolism of useless cholesterol in blood to liver, help stabilize serum cholesterol and regulate blood lipid; In addition, eggs are rich in lecithin, which helps to prevent atherosclerosis and is also good for blood vessel health.
