As soon as it sprouts, the toxicity soars
Potatoes are one of the most common foods in the world. They are the raw materials for French fries and potato chips. But in fact, the stems and leaves of potatoes and it itself contain poisonous solanine. When people eat 200 mg of solanine, it will cause vomiting, diarrhea, breathing difficulties, etc., and even death in severe cases. One kilogram of potatoes contains about 12-20 mg of solanine. The amount of potatoes that people usually eat is not up to the toxic level, but once the potato germinates, the solanine inside will increase to 250-280 mg. The epidermis contains 1500-2200 mg, and heating cannot decompose this toxin.
Therefore, if you see potatoes sprouted, don’t continue to eat them because you don’t want to waste them. We can plant it and wait for small potatoes to grow.
Poisonous Beans
Fresh kidney beans contain toxic substances such as lectins. Generally, they will be acutely poisoned when eaten more than 50 grams raw; high-temperature boiling can inactivate the lectins. When cooking kidney beans, it is easy to be heated unevenly, resulting in lectin residues.
Therefore, kidney beans have become a “high risk” food, but when thoroughly cooked, kidney beans are still safe and delicious.
The fresher the more poisonous
Day lily is a common vegetable in China. The strange thing is that day lily on the market is usually dried, and fresh day lily is rare. This is because fresh day lily contains colchicine, which is easy to produce toxic dicolchicine in the body after human consumption. Adults will be poisoned if they consume 50 to 100 grams at a time.
Colchicine is not heat-resistant, and it will be destroyed by boiling for about 10 minutes. Therefore, it is not that the seller is unwilling to sell fresh day lily, but for the sake of safety, the day lily is boiled and dried to help people “anti-virus” in advance.
A toxic staple food consumed by 600 million people
You may not know much about cassava, but the raw materials of common foods such as shrimp crackers, vermicelli, and pearls in bubble milk tea are cassava. It has high starch content and is called the “king of starch”. It is easy to grow and has a high yield. It is a staple food for nearly 600 million people worldwide. But this kind of cassava, which feeds countless people, contains the toxic substance linolein, which will be decomposed into a neurotoxin hydrocyanic acid under the action of human stomach acid after consumption, causing people to have symptoms such as dizziness and vomiting. Adults who eat 150 grams of fresh cassava may be poisoned and die.
Therefore, before consuming cassava, peel it off and soak it in water for a long time to dissolve the linolein in the water, and then cook it thoroughly before eating it. Most of the cassava products sold on the market have also undergone detoxification treatment.
The poisonous apple that stunned the princess
In the fairy tale, Snow White fell into a coma after eating a poisoned apple, and the apple in reality is indeed poisonous. It’s just that what is poisonous is not the pulp, but the seeds hidden in the pulp. Apple seeds contain the neurotoxin hydrocyanic acid. Generally, eating more than 150 apple seeds can cause nausea, diarrhea, dizziness, headache and even coma. On average, an apple has about 5 to 8 seeds. That is to say, if Snow White was poisoned by eating apple seeds, then she must have eaten nearly 20 apples in a row and chewed up all the seeds and swallowed them.
Some people have the habit of eating the seeds together when eating certain fruits. Although eating a few apple seeds when gnawing apples will not be immediately poisoned, long-term such a habit is also harmful to health, and it is best not to eat them.
