What are the most unhealthy food combinations?
Introduction: I've recently gotten into cooking, just learned it from my mom, but I'm not very knowledgeable about food pairings. What are some unhealthy food combinations? Don't worry, let's figure it out together.
In life, some food combinations have a long history, and their delicious flavors are widely accepted. It also feels natural to pair them this way out of habit. But from a health perspective, these pairings are not scientific. Health experts have plenty of reasons to say so. Here, I've listed 12 food combinations that health experts consider incorrect. However, some things just don't taste good otherwise, so I figure eating them this way occasionally might not be a big problem. If you value your health, it's best to listen to the experts' advice and stop mindlessly overindulging.
1. Stewed Beef and Potatoes:
Harm: Gastrointestinal dysfunction
Reason: Since potatoes and beef require different concentrations of stomach acid for digestion, this will inevitably prolong the food's residence time in the stomach. This, in turn, extends the time for gastrointestinal digestion and absorption. Over time, it will inevitably lead to gastrointestinal dysfunction.
2. Scallions with Tofu:
Harm: Impaired calcium absorption
Reason: The calcium in tofu and the oxalic acid in scallions combine to form a white precipitate—calcium oxalate—which also makes it difficult for the body to absorb calcium.
3. Beaten Eggs into Soy Milk:
Harm: Nutrients cannot be absorbed
Reason: The mucoprotein in eggs will bind with trypsin in soy milk, causing both to lose their nutritional value.
4. Tea-boiled Eggs:
Harm: Irritates the stomach and is not conducive to digestion and absorption
Reason: In addition to alkaloids, tea also contains acidic substances. These compounds bind with the iron in eggs, irritating the stomach and hindering digestion and absorption.
5. Adding Monosodium Glutamate (MSG) to Scrambled Eggs:
Harm: Destroys the natural umami of eggs
Reason: Eggs themselves contain a lot of glutamic acid, the same component as MSG. Therefore, adding MSG when scrambling 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:
Harm: Affects Vitamin C absorption
Reason: White radishes are extremely high in Vitamin C, but red radishes contain an enzyme called ascorbic acid dehydrogenase that breaks down Vitamin C. When red and white radishes are eaten together, the Vitamin C in the white radish is completely destroyed. Moreover, when cooked with vegetables rich in Vitamin C, the red radish acts as a destroyer. Cucumbers and pumpkins also contain similar dehydrogenase enzymes.
7. Eating Radishes with Fruit:
Harm: Induces or leads to goiter
Reason: 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—thiocyanate. The amount of this substance is directly proportional to the intake. If fruits rich in plant pigments like oranges, pears, apples, and grapes are consumed at the same time, the flavonoids in these fruits are broken down by bacteria in the intestine into compounds like hydroxybenzoic acid and ferulic acid. These can enhance the effect of thiocyanate in suppressing the thyroid, thus inducing or leading to goiter.
8. Eating Seafood with Fruit:
Harm: Produces indigestible substances that irritate the stomach
Reason: Seafood like fish, shrimp, and algae are rich in protein and calcium. If eaten with fruits containing tannic acid, not only is the nutritional value of the protein reduced, but the calcium in the seafood can also easily 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, hawthorns, and green plums. Therefore, these fruits should not be eaten with seafood dishes; a two-hour interval is recommended.
9. Milk with Oranges:
Reason: 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 cause symptoms like bloating, abdominal pain, and diarrhea.
10. Alcohol with Carrots:
Harm: Liver disease
Reason: Recently, American food experts have warned that eating carrots with alcohol is very dangerous. Experts point out that the rich beta-carotene in carrots, when entering the body with alcohol, produces toxins in the liver, leading to liver disease. In particular, you should not drink alcohol immediately after drinking carrot juice.
11. Baijiu (Chinese liquor) with Carbonated Drinks:
Harm: Seriously harms the stomach, intestines, liver, kidneys, and cardiovascular system
Reason: Because drinking baijiu and carbonated drinks together causes alcohol to vaporize quickly throughout the body and produces large amounts of carbon dioxide, which has serious harmful effects on organs like the stomach, intestines, liver, and kidneys, and also damages the cardiovascular system.
12. Drinking Tea While Eating Meat:
Harm: Constipation & increases the possibility of absorbing toxic and carcinogenic substances
Reason: Some people drink tea shortly after eating meat and seafood, 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. This slows down intestinal peristalsis, prolonging the time feces stays in the intestine. This not only easily leads to constipation but also increases the possibility of absorbing toxic and carcinogenic substances.
