We all know that eggs are very nutritious, and after being cooked in various ways, the taste is simply amazing! However, eggs, though good for you, can be harmful to your health if eaten improperly. See if you've fallen into any of the following situations?
Eating Raw
Some people believe that once food is cooked, it loses its nutritional value. That's why many people enjoy eating raw vegetables and seafood. Similarly, some think that eating raw eggs provides more nutrition than cooked ones.
However, this is not the case. Eating raw eggs can easily introduce bacteria (such as E. coli) into your system, causing gastrointestinal discomfort, diarrhea, and in severe cases, even death. Furthermore, it's worth mentioning that egg whites contain avidin, which needs to be destroyed by high heat. Otherwise, it can hinder the absorption of biotin in food, leading to symptoms like loss of appetite, general weakness, muscle pain, skin inflammation, and eyebrow loss.
Leftover
It's actually fine to cook eggs and then reheat them the next day. However, you cannot eat semi-cooked eggs after they've been left overnight! If eggs are not fully cooked, they can easily breed bacteria when stored improperly, causing issues like gastrointestinal discomfort and bloating.
At the same time, some believe that the longer you boil an egg, the better, which is also wrong. Boiling an egg for too long causes the ferrous ions in the yolk to react with the sulfide ions in the white, forming insoluble ferrous sulfide, which is difficult for the body to absorb. When fried eggs are overcooked, the edges can burn, and the high-molecular-weight proteins in the egg white are broken down into low-molecular-weight amino acids. These amino acids can form harmful chemical compounds for human health at high temperatures.
Excessive Consumption
As we know, eggs are high in protein. Consuming too many can lead to an increase in metabolic byproducts, placing an additional burden on the kidneys and potentially causing kidney damage. Therefore, it is generally advisable for the elderly to eat 1-2 eggs per day. For young and middle-aged people, or those engaged in mental or light physical work, 2 eggs per day is appropriate. For those engaged in heavy physical labor with higher nutritional needs, 2-3 eggs per day can be consumed. Children and adolescents, who are growing and have fast metabolisms, should also eat 2-3 eggs per day.
Pregnant women, nursing mothers, individuals who are weak, and patients recovering from major surgery need more high-quality protein and can consume 3-4 eggs per day, but no more.
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. Therefore, sugar should be added after the egg-based dish has cooled down.
Additionally, many people enjoy an egg, a piece of 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.
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 "compelled" to be burned as energy, rather than providing nutritional nourishment.
At the same time, a large amount of protein accumulating in a short period can lead to the production of large quantities of harmful substances like urea and ammonia during protein breakdown, which is not good for your health.
Tea Eggs
Tea eggs should be eaten in moderation. First, because they are repeatedly boiled, their nutritional value is diminished. Second, during this process, the acidic substances in the tea combine with the iron in the eggs, which can irritate the stomach and affect gastrointestinal digestion.
