Radish + Fruit — When consumed together, they can quickly produce large amounts of thiocyanate in the body after metabolism. Thiocyanate can inhibit the formation of thyroid hormones and obstruct the thyroid's iodine uptake, thereby inducing or causing goiter.
Milk + Fruit-Flavored Drink — Milk is rich in protein, with over 80% being casein. In an acidic environment with a pH below 4.6, casein will coagulate and precipitate, which is not conducive to digestion and absorption and can cause indigestion. Therefore, it is not advisable to add acidic drinks like Fruit-Flavored Drink or fruit juice when preparing milk.
Seafood + Fruit — Fish, shrimp, and algae are rich in nutrients such as protein and calcium. When consumed with fruits containing tannins, not only is the nutritional value of the protein reduced, but the protein from the seafood can also easily bind with the tannins. This substance can irritate the mucous membranes and form an indigestible mass, leading to symptoms like abdominal pain, nausea, and vomiting.
Meat + Tea — 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, prolongs the retention time of feces in the intestines, and leads to constipation.
Liquor + Carrot — Carrots are rich in carotene. When consumed with alcohol, it can produce toxins in the liver, thereby damaging liver function.
Pickled Fish + Lactic Acid Drink — Pickled fish should not be consumed with lactic acid drinks. Nitrates in pickled fish products are converted into nitrites by the action of lactic acid bacteria. Under the catalysis of thiocyanate ions in saliva, this can produce carcinogenic substances, potentially causing cancer in the gastrointestinal tract, liver, and other digestive organs.
