In daily life, some food combinations have a long history, and their delicious flavors are widely accepted. It has become customary to consider these pairings perfectly natural. However, from a health perspective, they are not scientific, and health experts have solid reasons for this. Here is a list of food combinations that health experts consider incorrect. That said, not eating them this way can make some foods less tasty, so perhaps eating them in moderation is not a big issue. If you are very concerned about your health, it's best to follow the experts' advice and not eat indiscriminately or greedily.
1. Scallions with Tofu: The calcium in tofu combines with the oxalic acid in scallions to form a white precipitate—calcium oxalate—which similarly hinders the body's absorption of calcium.
2. Eggs with Soy Milk: The mucoprotein in eggs combines with trypsin in soy milk, thereby losing their respective nutritional value.
3. Tea-Boiled Eggs: Besides alkaloids, tea contains acidic substances. These compounds combine with the iron in eggs, which can irritate the stomach and is not conducive to digestion and absorption.
4. Adding Monosodium Glutamate to Scrambled Eggs: Eggs themselves contain a lot of glutamic acid, the same component as monosodium glutamate. Therefore, adding MSG to scrambled eggs not only fails to enhance the umami flavor but can also destroy and mask the natural savory taste of the eggs.
5. Mixing Red and White Radishes: White radishes are extremely high in vitamin C, but red radishes contain an enzyme called ascorbin that breaks down vitamin C. When red and white radishes are combined, the vitamin C in the white radish is completely destroyed. Not only that, when cooked with vegetables containing vitamin C, the red radish acts as a destroyer. Cucumbers and pumpkins also contain similar enzymes to the red radish.
6. Eating Radishes with Fruits: In recent years, scientists have discovered that after cruciferous vegetables like radishes enter the human body, they metabolize quickly to produce an anti-thyroid substance—thiocyanic acid. The amount of this substance produced is proportional to the intake. At this time, if fruits high in plant pigments such as oranges, pears, apples, and grapes are consumed, the flavonoids in these fruits are broken down by bacteria in the intestine into substances like hydroxybenzoic acid and ferulic acid. These can enhance the effect of thiocyanic acid in inhibiting the thyroid, thus inducing or causing goiter.
7. Eating Seafood with Fruits: Seafood like fish, shrimp, and algae are rich in protein and calcium. If eaten with fruits containing tannic acid, it not only reduces the nutritional value of the protein but also easily causes the calcium in the seafood to combine with tannic acid to form a new substance that is difficult to digest. This substance can irritate the stomach, causing discomfort, stomach pain, vomiting, and nausea. Fruits with high tannic acid content include persimmons, grapes, pomegranates, hawthorns, and green plums. Therefore, these fruits should not be eaten with seafood dishes at the same time; a two-hour interval is advisable.
8. Drinking Milk with Oranges: Drinking milk and then immediately eating oranges causes the protein in the milk to meet the citric acid and vitamin C in the oranges and coagulate into lumps, affecting digestion and absorption. It can also cause bloating, abdominal pain, and diarrhea.
9. Drinking Alcohol with Carrots: Recently, American food experts have warned people that it is very dangerous to eat carrots with alcohol. Experts point out that because the rich beta-carotene in carrots enters the body along with alcohol, it will produce toxins in the liver, causing liver disease. This is especially true when drinking carrot juice.
10. Drinking White Liquor with Soda Water: Because drinking white liquor and soda water together will quickly cause the alcohol to volatilize throughout the body and produce a large amount of carbon dioxide, which has serious harm to organs such as the stomach, intestines, liver, and kidneys, and also damages the cardiovascular system.
11. Eating Meat and Then Drinking Tea: Some people drink tea soon after eating high-protein foods like meat and seafood, thinking it aids digestion. What they don't realize is that the large amount of tannic acid in tea combines with protein to form tannic acid protein, which has an astringent effect. This slows down intestinal peristalsis, thereby prolonging the time stool stays in the intestines. This not only easily leads to constipation but also increases the possibility of the body absorbing toxic and carcinogenic substances.
