A few days ago, Ah Nuan was so uncomfortable in the middle of the night that he vomited, and after examination, it was found that it was food poisoning. It can be seen that even if some vegetables are cooked, they can be harmful to health if they are not cooked!
After food poisoning, it can cause vomiting and diarrhea at mild level, and may lead to coma and shock in severe cases. Even if there is no obvious reaction, eating vegetables that have not been cleaned for a long time can be very harmful to the body.
In this issue, Ah Nuan has specially sorted out six common vegetables with toxins, so you should pay more attention! Don't take it lightly~
Nitrite-contained
Kale!
A N U A N - E A T I N G
Summer is the season when kale ripens in large numbers! I'm sure you've seen it at the dinner table, right?
Kale is a cruciferous vegetable, which is very nutritious, with a calcium content of up to 294mg/100g, nearly three times that of milk; It also contains fiber, vitamin K, carotene and various minerals, which is very worth enjoying~
But at the same time, it has a very high nitrite content! The nitrite of ordinary vegetables is about 1~1000mg/kg, while the nitrite of kale can be as high as 3071~5473mg/kg! [3]
Nitrite is an ingredient that may increase the risk of cancer in the body, so it is important to pay attention to it in your daily diet. If you want to remove nitrite from kale, boil it in boiling water for at least 1~2 minutes~
Other nitrite-rich vegetables are coriander, artemisia, fennel, celery, toon, etc. Among them, coriander is the easiest to eat raw, so please pay attention~
Hydrogen-sweet
Cassava!
A N U A N - E A T I N G
Do you like to eat a bowl of icy tapioca syrup in the summer? If you're making your own tapioca syrup, be sure to peel and simmer for at least 30 minutes.
There are two hydroglycosides in raw cassava, and when they are hydrolyzed, they both produce toxic hydrocyanic acid, which causes harm to the body. Vegetables that also contain hydroglycosides include ginkgo seeds and apricots.
Ah Nuan still remembers that Princess Wen Yi in "The Legend of Zhen Huan" hurt her spleen and stomach by eating cassava, and this plot is not unreasonable.
Because cassava is not only a toxin, but also a relatively difficult food to digest, if you don't have a good spleen and stomach, eat less cassava!
Susceptible to bacterial infections
Sprouts!
A N U A N - E A T I N G
Crisp and refreshing bean sprouts are one of the most common flavors in summer! But cold vegetables, the most afraid is that the vegetables are undercooked, especially "bacterial-carrying vegetables" like bean sprouts.
Bean sprouts are not inherently toxins, but they prefer to stay in a warm, moist environment.
Coincidentally, many pathogenic bacteria, such as Salmonella, Listeria, E. coli, etc., also love this environment, so they thrive happily together~
According to the U.S. Food and Drug Administration (FDA), between 1996 and August 2020, there were 52 foodborne illness outbreaks associated with contaminated sprouts, resulting in 2,700 infections.
It can be seen that even if we face small bean sprouts, we should not take it lightly, and it is best to blanch for 2~3 minutes. "Multi-bacterial" vegetables similar to bean sprouts include callus white, lettuce, cabbage, etc
Colchicine-contained
Daylily!
A N U A N - E A T I N G
Daylily tastes tender and refreshing, and is generally used in chicken soup, pork bone soup, etc., and the colchicine in it will slowly dissolve in the high temperature of the soup.
But if you want to eat the daylily cold, or fry it, then blanch it for 3~5 minutes.
According to the popular science of People's Daily Online, adults can cause colchicine poisoning symptoms by eating more than 100g of fresh daylily at a time [1].
And fresh daylily generally has more toxins than dried daylily, which is more likely to cause poisoning reactions. Old people often say that daylily is "eaten dry but not fresh", which is the truth.
Contains plant lectins
Green bean!
A N U A N - E A T I N G
Most legumes and vegetables contain a lot of dangerous ingredients such as plant lectins and saponins, in addition to the well-known green beans, there are kidney beans, lentils, and oil beans.
These ingredients need to be heated thoroughly before they disappear, so be sure to cook them in boiling water for at least 10 minutes to cook the beans! Cook thoroughly!
Some of the older wild beans may be rich in more dangerous ingredients, so you need to cook them for a longer time (from Ah Nuan's personal lesson).
Cyanide-containing
Fresh bamboo shoots!
A N U A N - E A T I N G
Bamboo shoots are delicious and everyone loves them! But we can't eat it raw, let alone eat too much, but we need to blanch it for 6~8 minutes before we can eat it, and 100g a day is enough.
It cannot be eaten raw because the cyanide content in the tips of fresh bamboo shoots is relatively high, which is toxic and can cause dizziness, skin redness, and even affect breathing. [2]
The reason why you can't eat too much in a day is because the fiber and tannic acid content in bamboo shoots is relatively high, and eating too much will increase the burden on the stomach.
Ah Nuan can often see videos of cute giant pandas showing off bamboo shoots, so envious! It's a pity that we don't have the stomach of a giant panda, so let's take it easy~
In addition to the above six foods with toxins, there are also some vegetables that need to be blanched:
For example, vegetables high in oxalic acid, such as spinach, callus white, purslane; There are also vegetables that are difficult to wash, such as broccoli, cauliflower, fungus. Health is no trivial matter, everyone must pay attention to the treatment of vegetables~
What other vegetables do you know of that contain toxins?
