Using the wrong methods to eat eggs can turn this excellent nutritional food into a poison! The following methods are incorrect ways to eat eggs. If you're doing any of them, you should correct them immediately!
1. Eating Raw
Some people believe that cooking food destroys its nutritional value. That's why many people prefer to eat vegetables and seafood raw. Similarly, some think that eating raw eggs provides more nutrition than cooked ones. However, this is not true. Eating raw eggs can easily introduce bacteria (like E. coli) into your system, causing gastrointestinal discomfort and diarrhea. Furthermore, it's worth mentioning that egg whites contain avidin, a substance that needs to be destroyed by high heat. Otherwise, it can interfere with the absorption of biotin in food, leading to symptoms such as loss of appetite, general weakness, muscle pain, skin inflammation, and even eyebrow loss.
2. Overnight
It's actually okay to cook eggs and reheat them the next day. However, you should not eat semi-cooked eggs that have been left overnight! If eggs are not fully cooked, they can easily breed bacteria if stored improperly, leading to issues like stomach upset and gas.
At the same time, some believe that the longer you boil an egg, the better. This is also wrong. Boiling an egg for too long causes the ferrous ions in the yolk to combine with the sulfur ions in the white, forming insoluble ferrous sulfide, which is difficult for the body to absorb. When fried eggs are overcooked, the edges get burnt, and the high-molecular-weight proteins in the egg white break down into low-molecular-weight amino acids. These amino acids can often form harmful chemical substances to human health at high temperatures.
3. Excessive Consumption
As we all know, eggs are high in protein. Consuming too many can lead to an increase in metabolic waste products, adding to the burden on the kidneys and potentially causing kidney damage. Therefore, for the elderly, 1-2 eggs per day is generally appropriate. For young and middle-aged people, or those engaged in mental or light physical labor, 2 eggs a day is fine; for those doing heavy physical labor who burn more nutrients, 2-3 eggs per day is suitable. Children and adolescents, who are growing and have fast metabolisms, should also eat 2-3 eggs daily. Pregnant women, new mothers, nursing mothers, the weak, and patients recovering from major surgery need more high-quality protein and can eat 3-4 eggs a day, but no more.
4. Adding Sugar or Soy Milk
Many people like to cook eggs with sugar. In fact, when eggs and sugar are cooked together at high temperatures, a substance called glycosyllysine is formed, which destroys the beneficial amino acids in the egg. It's worth noting that glycosyllysine has a blood-clotting effect and can be harmful to the body after ingestion. Therefore, sugar should be added only after the egg dish has cooled. Also, many people enjoy an egg with bread and a glass of soy milk for breakfast. However, the trypsin in soybeans combines with the ovomucoid in the egg white, leading to a loss of nutrients and reducing the nutritional value of both.
5. Eating on an Empty Stomach
Eating eggs on an empty stomach is not ideal. Consuming large amounts of high-protein foods like milk, soy milk, eggs, and meat on an empty stomach forces the protein to be "converted" into energy for consumption, negating its nutritional benefits. At the same time, an excessive accumulation of protein in a short period can produce a large amount of harmful substances like urea and ammonia during the breakdown process, which is not good for your health.
6. Fried Eggs and Tea Eggs
Many people like to eat fried eggs, especially those with golden, crispy edges. You should be cautious here, because the burnt edges cause the high-molecular-weight proteins in the egg white to break down into low-molecular-weight amino acids. These amino acids can often form carcinogenic chemical substances at high temperatures. Additionally, tea eggs should be eaten in moderation. First, their nutritional value is diminished by prolonged simmering. Second, the acidic substances in the tea can combine with the iron in the eggs, irritating the stomach and affecting digestion.
It seems there's a lot to pay attention to when eating a simple egg, but these are all tips worth noting. As long as we are mindful when we eat, we can effectively absorb the beneficial nutrients from eggs.
