Eggs are high-protein foods. Consuming too many can lead to an increase in metabolic waste products, placing a burden on the kidneys. Generally, it is appropriate for children and the elderly to eat one egg per day, while teenagers and adults can eat two. The following are precautions to take after eating eggs.
Do not drink tea immediately after eating eggs
Some people have the habit of drinking tea immediately after eating high-protein foods like meat, eggs, and seafood, believing it helps to "remove the taste" and "aid digestion." In fact, this practice is not scientific. Because tea contains a large amount of tannic acid, which combines with protein to form astringent tannic acid protein. This slows down intestinal peristalsis, thereby prolonging the time feces stays in the intestine. This not only easily causes constipation but also increases the possibility of toxic and carcinogenic substances being absorbed by the body, harming human health.
Life Tip: Avoid eating undercooked eggs
The egg white contains avidin, which affects the absorption of biotin in food, leading to symptoms such as loss of appetite, general weakness, muscle pain, skin inflammation, and eyebrow loss. Eggs also contain anti-trypsin, which affects the human body's digestion and absorption of egg protein. These two substances are not broken down in undercooked eggs, 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 eaten after being cooked at high temperatures; do not eat undercooked eggs. The protein structure of a raw egg 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 such as saliva, gastric juice, and intestinal juice, leading to loss of appetite and indigestion.
The benefits of eggs
1. Brain-boosting and intelligence-enhancing. The lecithin, triglycerides, cholesterol, and vitellin in the egg yolk have a significant effect on the nervous system and physical development. They can prevent intellectual decline in the elderly and improve memory in all age groups.
2. Liver protection. The protein in eggs has a repairing effect on liver tissue damage. The lecithin in the egg yolk can promote the regeneration of liver cells and also increase the human body's plasma protein level, enhancing the body's metabolic and immune functions.
3. Preventing and treating arteriosclerosis. American nutritionists and medical workers used eggs to prevent and treat atherosclerosis and achieved surprisingly remarkable results.
4. Cancer prevention. Eggs contain a relatively high amount of vitamin B2, which can decompose and oxidize carcinogenic substances in the human body. Trace elements in eggs, such as selenium and zinc, also have anti-cancer effects.
5. Delaying aging. Eggs contain almost all the nutrients the human body needs, so they are called the "ideal nutrient library." Nutritionists call it the "complete protein model," and it is one of the longevity experiences of many long-lived people.
The most nutritious cooking method:
There are many ways to eat eggs. In terms of nutritional absorption and digestibility, a boiled egg is 100%, a scrambled egg is 97%, a soft-fried egg is 98%, a hard-fried egg is 81.1%, an egg beaten into boiling water or milk is 92.5%, and a raw egg is 30%-50%. Therefore, boiling eggs is the best way to eat them, but be sure to chew slowly, otherwise it will affect absorption and digestion. However, for children, steamed egg custard and egg drop soup are the most suitable, as these two methods break down the protein, making it extremely easy for children to digest and absorb.
Note: Tea eggs should be eaten in moderation because the acidic substances in tea combine with the iron in eggs, irritating the stomach and affecting gastrointestinal digestion.
Is the white better or the yolk better?
The correct way to eat is to eat the whole egg. The egg white contains more protein, while the yolk contains more other nutrients.
