Which foods should not be eaten together is truly a big subject. For this, we provide information on dietary taboos, food incompatibilities, and dietary restrictions for special groups, hoping everyone can correct incorrect dietary concepts and cultivate good eating habits.
Carp should not be eaten with pickled vegetables
Carp is rich in protein, while pickled vegetables contain nitrites. When cooked together, they can form a carcinogen—nitrosamine, which can easily lead to digestive tract cancers.
Tip: When eating carp, pair it with fresh vegetables.
Ham and cured products should not be paired with lactic acid beverages
Ham and cured products both contain nitrates, which can be reduced to nitrites by the action of lactic acid bacteria. Under the catalysis of thiocyanate ions in saliva, this can produce carcinogens and may cause cancer in the stomach, intestines, liver, and other digestive organs.
Tip: Do not drink lactic acid beverages within 1 hour before or after consuming foods containing nitrates.
Don't drink tea when eating mutton
Mutton is rich in protein, and tea contains a significant amount of tannic acid. Drinking tea with mutton produces tannic acid protein, which weakens intestinal peristalsis and reduces water in the stool, thereby inducing constipation. Constipation can lead to increased absorption of intestinal toxins and is more likely to cause digestive tract tumors.
Tip: Fruits with high tannic acid content, such as persimmons, grapes, pomegranates, and hawthorns, should also not be eaten with mutton. There should be an interval of at least 2 hours.
Radishes should not be eaten with fruit
In recent years, scientists have discovered that after cruciferous vegetables like radishes enter the human body, they are quickly metabolized into a substance that affects the thyroid—thiocyanic acid. If, at this time, fruits high in plant pigments, such as apples and pears, are consumed, the flavonoids in these fruits are broken down by intestinal bacteria into substances like hydroxybenzoic acid. These can enhance the thyroid-suppressing effect of thiocyanic acid, leading to goiter. Long-term goiter may induce thyroid cancer.
Tip: After eating cruciferous vegetables like radishes, wait at least 4 hours before eating fruit.
