Eggs are the most common ingredient on our dinner table. They are nutritious, inexpensive and widely available to everyone from 4 to 5 month old babies to the elderly. From a nutritional point of view, eggs are rich in protein, especially high-quality protein. Each hundred grams of eggs contains 12.7 grams of protein, and two eggs contain roughly the same amount of protein as three fish or lean meat. The digestibility of egg protein is also highest in milk, pork, beef and rice. In addition, eggs have many micronutrients, such as potassium, sodium, magnesium, phosphorus and especially iron in the yolk up to 7 mg/100 g. Although eggs are a necessity in our lives, there are some situations that need to be taken care of ……. Eating eggs is good for the body, and I believe that in the minds of many people, this statement is basically not accepted as any rebuttal. Eating an egg every day not only provides high-quality protein and a variety of vitamins and minerals, but also improves memory and protects eyesight. But are all eggs good eggs? The answer is of course no, eat the right egg, only good eggs, accidentally eat the “bad eggs”, the body will also cause some harm, be careful! The first “bad eggs”: eggs lead, sodium content is high Many people love to eat eggs, go out to order cold dishes, red pepper eggs is also a very high order rate of dishes, no eggs lean pork porridge porridge store that is certainly not called porridge store. However, because of the production process, the lead content of the eggs is relatively high. If you often eat eggs, lead may accumulate in your body, and the consequences of lead overdose are very serious. It may lead to anemia, high blood pressure, kidney damage in adults, miscarriage, premature birth, baby deformity in pregnant women, and also affect the intellectual development of children. Eggs are invisible salt foods with a high sodium content, with five times the sodium content of fresh duck eggs. For people with high blood pressure who need to control sodium intake, they must be consumed with caution. In addition, for children and pregnant mothers, the absorption rate of lead is higher than the general population, especially children are more sensitive to lead (the absorption rate of soluble lead in the gastrointestinal tract of children is 40% to 50%, while that of adults is only 3% to 10%). In order to reduce the risk, it is recommended that these two groups of people should be “prohibited” from eating eggs. For normal people, it is safe to eat one or two eggs once in a while, as they are more alkaline, it is best to add a small amount of vinegar to neutralize the alkalinity. “Bad eggs” second place: sugar eggs eaten often may be poisoned eggs in the protein and high concentration of sugar cooked together for too long, will occur in the “Murad reaction”: let the blood fructose machine lysine. This substance has a blood clotting effect, if often eaten this substance is likely to have a toxic reaction! It is recommended to break the eggs and make them into egg flowers, and then put the sugar in the end, so that there will be no Merad reaction. This makes the sugar egg, you can eat with confidence. The third “bad egg”: tiger eggs may induce cancer tiger eggs are fried. Deep-fried eggs are fried proteins, and high-temperature frying can lead to the accumulation of proteins in our intestines for too long, which can cause cancer; and can lead to excessive oxidation of cholesterol, which is not good for blood vessels. So be sure to eat as little as possible. The fourth “bad egg”: hairy eggs Bacterial buildup Hairy eggs are actually fertilized eggs that are infected with salmonella during the process of oviposition of the chick, resulting in a dead chicken fetus, which is an egg that has not successfully completed oviposition. The egg itself is made up of bacteria, and even after being cooked at high temperatures, all that remains is bacteria. The fifth “bad egg”: cracked eggs are susceptible to bacterial invasion. Eggs are susceptible to bacterial invasion due to vibration and extrusion during transportation, storage and packaging, which can cause cracks and cracks in some eggs. The sixth “bad egg”: eggs with spots Salmonella infection Generally speaking, eggs with spots on the shell are best not to eat, because such eggs with spots are likely to be infected with bacteria, especially Salmonella, which can be fatal in serious cases. At a constant temperature, eggs have a shelf life of only about half a month, and they are more likely to deteriorate in hot weather. Eggs with spots on the surface do not appear to have obvious signs of spoilage, but in fact the quality of the egg has deteriorated and is not fresh enough. The seventh “bad egg”: overnight semi-cooked eggs gastrointestinal flatulence The Second Affiliated Hospital, Department of Gastroenterology, chief physician Du Fangteng reminded, semi-cooked eggs, after overnight it is best not to eat, eggs are not fully cooked, in the case of improper storage is easy to breed bacteria, such as causing gastrointestinal discomfort, flatulence and other situations. The eighth “bad egg”: stillborn eggs are toxic! Eggs that are contaminated by bacteria or parasites during incubation, coupled with poor temperature and humidity conditions, cause the embryo to stop developing and are called stillborn eggs. These eggs have changed nutritionally, and if they have been dead for a long time, the proteins are broken down to produce a variety of toxic substances, so they should not be eaten. The ninth name of “bad eggs”: loose yolk eggs Bad stomach Due to transportation and other intense oscillation, the yolk membrane rupture, resulting in mechanical loose yolk, or stored for too long, by bacteria or mold through the eggshell stomata invade the egg body, and destroy the protein structure caused by loose yolk, egg liquid thin cloudy. If the loose yolk is not serious and there is no odor, it can still be eaten after high-temperature treatment such as decoction, but if bacteria breed in the egg, the protein is denatured and there is a bad smell, it cannot be eaten. The tenth name of “bad eggs”: sticky eggs harmful to the body This kind of eggs because of the storage time is too long, the yolk membrane from tough to weak, yolk tightly attached to the eggshell, if the local is red can also eat, but the egg membrane tightly attached to the eggshell immobile, outside the skin is dark black, and there is an odor, should not eat again. An egg a day, nutritious and healthy. But remember to try to avoid the 10 kinds of “bad eggs”!
