Debunking Myths: Are Online Claims About "Food Incompatibilities" Reliable?
A registered dietitian from the Nutrition Department at Changsha Central Hospital explains "food incompatibilities."
Claim: Eating persimmons and crabs together causes poisoning because persimmons contain high levels of tannic acid, while crabs are rich in protein. If consumed together in large quantities, tannic acid and protein combine in the gastrointestinal tract, easily forming gastric persimmon stones.
Fact Check: This claim lacks scientific basis. Whether consumed together or separately, foods react identically in the human body. Nutrition expert Professor Zheng Ji personally tested various food combinations, documenting no adverse reactions. However, individuals with weak digestive systems or poor health may experience effects.
Excessive persimmon consumption alone can indeed cause constipation and other gastrointestinal issues.Crab contains relatively high cholesterol, which can disrupt blood lipids and trigger pancreatitis. Therefore, no food should be consumed excessively; one cannot discuss the benefits or harms of any single item without considering quantity.
Rumor: Seafood and lemon should not be eaten together because seafood combined with vitamin C-rich foods becomes as toxic as arsenic?
Analysis: This is another classic example of discussing effects without considering quantity.Seafood contains trace amounts of arsenic. While vitamin C's antioxidant properties can convert non-toxic pentavalent arsenic in seafood to toxic trivalent arsenic, consuming enough to reach toxic levels for humans would require eating enormous quantities.
Claim: Radishes and oranges can cause goiter?
Analysis: Oranges do not cause goiter. Radishes do contain a substance that can lead to thyroid enlargement. However, if your thyroid function is normal, it's not a concern. If you have thyroid issues, avoid radishes and oranges—not just together, but individually as well.
Rumor: Eating leeks and spinach together causes diarrhea?
Fact: Both leeks and spinach are high in dietary fiber. For constipation, leeks can stimulate bowel movements. Those with constipation may consciously increase leek intake, but remember: moderation is key.
Rumor: Does eating lamb and mung beans together—combining cooling and warming foods—cancel out their therapeutic effects?
Fact: There is no cancellation effect. Ingested foods undergo further breakdown into proteins, fats, or glucose, fundamentally altering their inherent properties. Lamb is indeed a warming food; its high protein content generates heat during digestion, creating a warming sensation.Mung bean soup does have a cooling effect, but eating them together doesn't cancel each other out. Their effects are different and don't actually influence each other.
Foods prone to causing food poisoning mainly include:
1. Grain-based foods: Grain products like rice and rice cakes are susceptible to contamination by Bacillus cereus and Staphylococcus aureus, leading to Bacillus cereus or staphylococcal enterotoxin food poisoning.Poisonous mushrooms, moldy sugarcane, undercooked soy milk, kidney beans, and sprouted potatoes are common causes of food poisoning in China.
2. Fish and shellfish: The primary pathogen associated with poisoning from fish and shellfish is Vibrio parahaemolyticus. Poisoning often occurs in regions where raw fish and shellfish are commonly consumed or when improperly processed foods are eaten.Certain non-bacterial foodborne illnesses are also closely linked to seafood, such as pufferfish poisoning, toxic shellfish poisoning, and histamine poisoning. 3. Non-animal-derived foods: Although foodborne illnesses from non-animal sources are less common than those from animal products, they pose no lesser risk.Food poisoning from vegetables and fruits contaminated with pesticides or intestinal pathogens like Shigella or pathogenic E. coli is also a significant concern. Food poisoning is intrinsically linked to food sources. Therefore, it is crucial and necessary to pay close attention to foods that can cause poisoning, actively understand them, and implement relevant preventive measures to safeguard health. For patients, timely and effective treatment is paramount.

4. Younger students are often in the process of losing baby teeth. Avoid excessive snacking and maintain consistent oral hygiene to ensure the growth of strong, straight, and white teeth.
5. When purchasing food, carefully check the manufacturer, production date, and expiration date.
6. Regularly disinfect household tableware. Keep kitchens well-ventilated to prevent mold growth.
7. Children often enjoy holding objects in their mouths, especially hard items. These can easily slip down the throat and harbor bacteria, causing discomfort or even danger.
8. Avoid picking fruit from orchards without permission, as it may contain pesticide residues that could cause poisoning.
