A fertilized egg, without the help of nutritional assistance, only needs the right temperature and humidity, and with its own nutrients, it can complete the whole process of a chick’s growth and development to hatching. However, the natural nutritional advantages of eggs can really support people so capricious, since eggs are so good nutrition, is it possible for us to eat very capriciously? 1, eggs overcooked General boiling, steaming eggs should be controlled within 10 minutes, too long, in addition to poor taste, protein will also (solidification) become old, so that people do not digest. In addition, steaming and frying eggs for too long, but also let the fat and cholesterol oxidation level rises rapidly, nutrition can be greatly reduced. 2, eggs at once to eat too many eggs delicious, cheap and nutritious, does not mean that you can be very capricious binge eating. The “Dietary Guidelines for Chinese Residents 2016” recommends not to eat more than 7 eggs per week, as to how many, it depends on the situation, for example: (1) normal adults, the elderly, it is recommended to eat 1 egg per day; (2) children, pregnant women, lactating mothers and people who exercise a lot, due to the high demand for protein, you can eat 1 to 2 eggs per day; (3) patients with cholecystitis can eat egg whites, egg yolks (4) liver and kidney dysfunction, ask the doctor’s advice before eating, after all, too much protein will increase the burden on the kidneys. In fact, most of the nutrition of eggs is still in the yolk. But many folks are afraid of high cholesterol, eat eggs are used to throw away the yolk, only eat the egg white. Strange, how people cholesterol has become a bad thing, it is also an important component of the body every cell needs, in fact, the real should be afraid of, is cholesterol oxidation. However, the egg yolk itself is not guilty, its cholesterol is wrapped tightly, it is difficult to contact with oxygen, those improper cooking is the culprit of creating oxidized cholesterol, such as baked egg yolk, scrambled eggs, fried eggs …… 4, use eggs to supplement iron The iron content of egg yolk is not low, but the absorption rate is very low, but animal food. For example, liver, red meat, not only high iron content, absorption rate is also. So, don’t rely on eggs for iron. In addition, eggs as the second largest allergen, it is quite a lot of people allergic to it, especially the baby’s first mouthful of complementary food, do not eat eggs. 5, pick the color to eat eggs Grass eggs, green eggs …… the reason why the color is different, not by the taste of the chicken, but by the breed of chicken, and these different colors shell eggs in nutrition, taste and there is no difference. On the contrary, grass eggs, which are free-range all year round, are a little more likely to be polluted by the environment. So, don’t be obsessed with the earth eggs either.
