2, rice and fruit: rice is easy to be heated, fruit is easy to evaporate water and dry up when heated, rice will also absorb water, mold or insects.
3, bread and biscuits: biscuits are dry, no water, and bread has more water. When they are put together, cookies will become soft and lose their crispness, and bread will become hard and not delicious.
4, cucumbers and tomatoes: cucumbers avoid ethylene, tomatoes contain ethylene, which will make cucumbers deteriorate and rot.
5, shallots with tofu: calcium in tofu and oxalic acid in onions will combine into white precipitated calcium oxalate, which also makes it difficult for the human body to absorb calcium.
6. Wash eggs with soybean milk: Mucin in eggs will combine with trypsin in soybean milk, thus losing its due nutritional value.
7. Scrambled eggs with monosodium glutamate: The eggs themselves contain a lot of glutamic acid with the same composition as monosodium glutamate, so when scrambled eggs are put with monosodium glutamate, it not only does not increase the umami flavor, but will destroy and cover up the natural umami flavor of the eggs.
8. Mixing carrots and radishes: The content of vitamin C in radishes is extremely high, but carrots contain an ascorbic acid decomposing enzyme, which will destroy the vitamin C in radishes. Once carrots and radishes are matched, vitamin C in radishes will be lost. Not only that, carrots play a destructive role when cooking with vegetables containing vitamin C, as well as gourds and pumpkins. It also contains decomposition enzymes similar to carrots.
9. Eat radish and fruit together: In recent years, scientists have found that after cruciferous vegetables such as radish enter the human body, they will soon produce a substance that inhibits thyroid gland after metabolism, and the amount of this substance is directly proportional to the intake. At this time, if the fruit contains a lot of plant pigments, such as oranges, pears, apples, grapes and so on. When ingested, the flavonoids in these fruits are decomposed by bacteria in the intestine and converted into hydroxybenzoic acid and ferulic acid, which can strengthen the inhibitory effect of thiocyanic acid on thyroid, thus inducing or leading to goiter.
10. Eat seafood and fruit together: Fish, shrimp and algae in seafood are rich in nutrients such as protein and calcium. If eaten with fruits containing tannic acid, it will not only reduce the nutritional value of protein, but also easily combine calcium in seafood with tannic acid into new indigestible substances, which will stimulate the stomach and cause discomfort, abdominal pain, vomiting, nausea and other symptoms. Fruits with more tannic acid include persimmon, grape, pomegranate, hawthorn and olive. Therefore, these fruits should not be eaten with seafood at the same time, and the interval is 2 hours.
1 1. Eat oranges with milk: When you eat oranges just after drinking milk, protein in the milk will first meet the fruit acid and vitamin C in the oranges, and solidify into pieces, which will affect digestion and absorption, causing abdominal distension, abdominal pain, diarrhea and other symptoms.
