In life, some food combinations have a long history, and their wonderful flavors are widely accepted. By habit, these pairings seem perfectly natural. However, from a health perspective, they are not scientific, and health experts have sound reasons for this. Here is a list of 12 food combinations that health experts consider incorrect. However, some things are just hard to eat without these combinations, so I suppose eating them occasionally might not be a big problem. If you place a high value on your health, it's best to follow the experts' advice and not overindulge or eat indiscriminately.
1. Beef and Stewed Potatoes: Since potatoes and beef require different concentrations of gastric acid for digestion, they will inevitably prolong the time food stays in the stomach, thereby extending the time for gastrointestinal digestion and absorption. Over time, this will inevitably lead to gastrointestinal dysfunction.
2. Tofu with Scallions: The calcium in tofu and the oxalic acid in scallions combine to form a white precipitate—calcium oxalate—which similarly makes it difficult for the body to absorb calcium.
3. Eggs Mixed with Soy Milk: The mucoprotein in eggs will combine with the trypsin in soy milk, thereby losing their respective nutritional value.
4. Tea-Boiled Eggs: Besides alkaloids, tea also contains acidic substances. These compounds combine with the iron in eggs, which can irritate the stomach and is not conducive to digestion and absorption.
5. Adding MSG to Scrambled Eggs: Eggs themselves contain a lot of glutamic acid, the same component as MSG. Therefore, adding MSG to scrambled eggs not only fails to enhance the umami but also destroys and masks the natural flavor of the eggs.
6. Eating Red and White Radishes Together: White radishes are extremely high in vitamin C, but red radishes contain an enzyme called ascorbic acid oxidase, which destroys the vitamin C in white radishes. Once red and white radishes are combined, the vitamin C in the white radish will be completely lost. Moreover, when cooked with other vegetables containing vitamin C, the red radish plays a destructive role. Cucumbers and pumpkins also contain similar decomposition enzymes.
7. Radishes and Fruits Together: In recent years, scientists have discovered that after cruciferous vegetables like radishes enter the body, they are metabolized into a substance that inhibits the thyroid—thiocyanate. The amount of this substance produced is proportional to the intake. At this time, if fruits rich in plant pigments such as oranges, pears, apples, and grapes are consumed, the flavonoids in these fruits are decomposed by bacteria in the intestine into substances like hydroxybenzoic acid and ferulic acid. These can enhance the effect of thiocyanate in inhibiting the thyroid, thereby inducing or causing goiter. [Chinese Cuisine]
8. Seafood and Fruits Together: Seafood like fish, shrimp, and algae are rich in protein and calcium. If consumed with fruits containing tannic acid, it not only reduces the nutritional value of the protein but also causes the calcium in the seafood to combine with the tannic acid to form a new, indigestible substance. This substance can irritate the stomach and cause discomfort, leading to symptoms like stomach pain, vomiting, and nausea. Fruits with high tannic acid content include persimmons, grapes, pomegranates, hawthorn, and green plums. Therefore, these fruits should not be eaten with seafood dishes; it is advisable to wait for at least two hours.
9. Milk and Oranges Together: Drinking milk and then immediately eating oranges will cause the protein in the milk to curdle upon contact with the citric acid and vitamin C in the oranges, affecting digestion and absorption. It can also lead to symptoms like bloating, abdominal pain, and diarrhea.
10. Alcohol and Carrots Together: Recently, American food experts have warned that eating carrots with alcohol is very dangerous. Experts point out that because the rich beta-carotene in carrots and alcohol enter the body together, they produce toxins in the liver, which can cause liver disease. In particular, you should not drink alcohol immediately after drinking carrot juice.
11. White Liquor and Carbonated Drinks Together: Drinking white liquor and carbonated drinks together will quickly cause the alcohol to spread throughout the body and produce a large amount of carbon dioxide, which has serious harmful effects on organs such as the stomach, intestines, liver, and kidneys, and also damages the cardiovascular system.
12. Eating Meat and Then Drinking Tea: Some people drink tea shortly after eating meat or other high-protein foods, thinking it aids digestion. However, the large amount of tannic acid in the tea combines with protein to form tannic acid protein, which has an astringent effect and slows down intestinal peristalsis, thereby prolonging the time feces stays in the intestine. This not only easily leads to constipation but also increases the possibility of the body absorbing toxic and carcinogenic substances.
