Soymilk is usually not toxic, but some people may be poisoned if they drink undercooked or spoiled soymilk. Under normal circumstances, people who drink soy milk in moderation will not be poisoned. However, some people may be poisoned by drinking undercooked soymilk, which is mainly related to the fact that soymilk contains trypsin inhibitors, anticoagulants, and saponins that have not been destroyed by high temperatures. If people drink spoiled soymilk, food poisoning may occur due to the presence of Salmonella, Clostridium botulinum and Shigella in soymilk. For those who are clearly poisoned by soymilk, they should promptly induce vomiting, gastric lavage, catheterization, enema, etc., in order to reduce the impact of toxic substances on the health of the organism. It is worth noting that the crowd should avoid drinking soymilk directly from the refrigerator, so as not to cause intestinal spasms in those with sensitive gastrointestinal tracts, causing diarrhea, vomiting and other discomforts. It is recommended that the crowd drink a moderate amount of freshly boiled soybean milk, to avoid excessive drinking soybean milk. Pay attention to the rationality of the daily diet to ensure a balanced intake of nutrients and food freshness. People who are allergic to soy should not drink soy milk.
