Overall

Needless to say, this is a dish that goes very well with rice. Just a small reminder, it contains a soul ingredient, HONGKONG COOKED OLIVE VEGETABLE.

Toxins From Undercooked Long Green Beans

Long green beans without well cooked contain two toxins: lectins and saponins, which can only be broken down at high temperatures. If uncooked beans are consumed, these toxins will irritate the gastrointestinal tract and cause poisoning symptoms such as nausea, vomiting, stomach pain, abdominal pain, diarrhea, etc.

A Story: Mild Poisoning after Eating Uncooked Long Beans and Self-help

This dish is really delicious and goes well with rice, but unfortunately, I had stomach pain at around 3am, and the pain woke me up from my sleep. Besides, drinking warm water did not relieve the pain, and I guessed that I was slightly poisoned by eating uncooked long beans. So I tried to search online for self-help methods after poisoning, and the result was that I needed to drink a lot of warm strong tea, and then urinate to excrete the toxins. This method really worked. After more than two hours of drinking strong tea and urinating, the stomach pain was finally relieved.

Postscript

In fact, saponin toxins and phytohemagglutinin toxins are soluble in water and are not resistant to high temperatures. Although long green beans begin to change color and soften after being boiled in high-temperature water for 2 minutes, this is not enough. I checked online and found that some people used long green beans boiled for different times to add reagents to conduct experiments. After 5 minutes of boiling, beans still contain a certain amount of toxins. It takes nearly 10 minutes of complete high-temperature cooking time to basically eliminate the toxins.

Final

Food safety has always been an issue that cannot be ignored, and in this place where you have to wait for hours at any time for emergency treatment, some self-help methods must be mastered. Last of the last, huge thanks to the father of the Internet, Tim Berners-Lee, we can quickly share information and make the world more closely connected..
