1. Stewed Beef with Potatoes: Since potatoes and beef require different concentrations of stomach acid for digestion, they will inevitably prolong the food's residence time in the stomach. This, in turn, extends the time for gastrointestinal digestion and absorption. Over time, this will inevitably lead to gastrointestinal dysfunction.
2. Tofu with Scallions: The calcium in tofu combines with the oxalic acid in scallions to form calcium oxalate, a white precipitate that similarly makes it difficult for the body to absorb calcium.
3. Egg Whites in Soy Milk: The mucoprotein in eggs will combine with trypsin in soy milk, thereby losing the respective nutritional value of both.
4. Tea-Steamed 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 when scrambling eggs not only fails to enhance the umami flavor but can also destroy and mask the natural savory taste 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 dehydrogenase, which breaks down and destroys the vitamin C in white radishes.
7. Seafood with Fruit: Seafood such as fish, shrimp, and algae are rich in protein and calcium. If consumed with fruits containing tannic acid, it will not only reduce the nutritional value of the protein but also easily cause the calcium in the seafood to combine with tannic acid, forming a new substance that is difficult to digest.
8. Milk with Oranges: Drinking milk and then immediately eating oranges will cause the protein in the milk to meet the citric acid and vitamin C in the oranges, coagulating into clumps and affecting digestion and absorption.
9. Alcohol with Carrots: Consuming alcohol and carrots together is very dangerous. Because the rich beta-carotene in carrots enters the body along with alcohol, it can produce toxins in the liver, leading to liver disease. In particular, do not drink alcohol immediately after drinking carrot juice.
