We consider eggs a health food, as regular consumption can enhance memory, protect the heart and arteries, prevent cancer, and slow down aging. However, if not prepared and eaten correctly, this health food can become "waste" or even "poison." Therefore, it's important to understand the proper way to handle eggs to prevent problems before they occur.
Note: Eating eggs in these ways is harmful to your health
1. Avoid eating undercooked eggs
The protein in raw eggs contains avidin, which interferes with the absorption of biotin from food, leading to symptoms such as loss of appetite, general weakness, muscle pain, skin inflammation, and eyebrow loss. Eggs also contain antitrypsin, which affects the human body's digestion and absorption of egg protein. In undercooked eggs, these two substances are not broken down, thus affecting protein digestion and absorption. Eggs can be contaminated with bacteria during formation, and undercooked eggs cannot kill these bacteria, easily causing diarrhea. Therefore, eggs should be cooked at high temperatures before eating; do not eat undercooked eggs.
The protein structure of raw eggs is dense, and a large portion cannot be absorbed by the human body. Only when cooked does the protein become soft, allowing the human gastrointestinal tract to digest and absorb it. Raw eggs have a special fishy smell that can suppress the central nervous system, reducing the secretion of digestive fluids like saliva, gastric juice, and intestinal juice, leading to loss of appetite and indigestion.
2. Avoid overcooked eggs
If eggs are boiled for too long, a gray-green layer of iron sulfide will form on the surface of the yolk, which is difficult for the body to absorb. The protein will also become hard and tough as it ages, affecting appetite and making it less absorbable.
3. Eggs should not be boiled with sugar
Boiling eggs with sugar at high temperatures produces a substance called glycosyllysine, which destroys the beneficial amino acids in eggs. This substance also has a blood-clotting effect and can be harmful to the body after entering it. If you need to add sugar to boiled eggs, you should wait until they have cooled slightly before stirring it in; the flavor will not be diminished.
4. No need to add MSG when frying eggs Some people often soak cooked eggs in cold water, using the different thermal expansion coefficients of the eggshell and the albumen to make the shell easier to peel. However, this practice is unhygienic. Fresh eggs have a protective layer on their surface that prevents moisture from evaporating and stops microorganisms from entering. After the egg is cooked, this membrane on the shell is destroyed, and some gas from the air chamber inside escapes. Placing the egg in cold water causes the temperature in the air chamber to drop rapidly and creates a negative pressure. Cold water and microorganisms can then enter the egg through the pores in the shell and the double membrane inside, making it prone to spoilage during storage.
