The master who often cooks must know that green beans will be poisoned if they are not cooked. In fact, in the vast vegetable world, apart from green beans, there are many other foods that must be cooked before they can be eaten. Today, Yuer will take a look at the food that will be poisoned if it is not cooked.

Green beans

Green beans contain an alkaloid called soap horn, which has a strong stimulation to the mucous membrane of the digestive tract, causing local gastrointestinal congestion, swelling, nausea and vomiting, abdominal pain and limb numbness. This is only light, this soap horn can also destroy red blood cells, so that hemoglobin overflow from the cells, suffering from hemolysis, there will be anemia, jaundice, hepatosplenomegaly and other symptoms.

Green beans can destroy their toxicity as long as they are heated to more than 100 ℃. If there is really unfortunate food poisoning, the incubation period generally ranges from 10 minutes to several hours. Mild beans can recover in 3 days and a few hours with good physique. Only need to lie still, a small number of times to take sugar boiled water, if the poisoning is serious, there is hemolysis, should be promptly sent to the hospital for treatment.

Ginkgo

Ginkgo is a kind of traditional Chinese medicine, which can be eaten when cooked. It is nutritious and has the effects of moistening the lungs, resolving phlegm and relieving asthma, and the flavonoids in ginkgo have been used for the treatment of cardiovascular diseases a long time ago.

The nucleolus of ginkgo contains toxic substances called ginkgolic acid and bitter almond. Ginkgolic acid is an allergen, which is extremely easy to cause allergic reactions, which can lead to local redness, swelling, peeling, and even shock; bitter almond will decompose into hydrocyanic acid when it comes into contact with water, and hydrocyanic acid will combine with various cytopigments in the cells, making it lose the role of delivering oxygen in red blood cells to cells, resulting in cell asphyxiation.

In general, ginkgo can be peeled and soaked in water for an hour and then heated to eat, which can reduce toxicity.

Fresh fungus

Auricularia auricula is a kind of edible fungus, which has the effect of replenishing qi and activating blood circulation. But the fresh fungus that has just been picked is poisonous and must be soaked and dried before it can be eaten.

Fresh Auricularia auricula contains a phylloid photosensitive substance. If you eat fresh auricularia auricula raw for a long time, you will get "purpura". This disease is also known as vampire disease. Patients in the sun, the skin will blister, feel burning and pain, just like vampires.

Zizania caduciflora

What? Zizania latifolia can't be eaten raw!

Yes! Because Zizania caduciflora contains a lot of oxalic acid, oxalic acid in the intestinal tract will combine with calcium oxalate to form calcium oxalate, calcium oxalate is difficult to be absorbed by the human body, for a long time, will suffer from stones.

You can blanch it with water before eating to reduce the content of oxalic acid.

Cauliflower

Cauliflower contains a substance called colchicine, which sounds pretty good, doesn't it? Actually this is not so.

This substance itself is non-toxic, but as long as it is absorbed by the intestines and stomach, it will be oxidized into "colchicine" in the body, which is highly toxic and can stimulate the respiratory tract, stomach and intestines, causing symptoms of nausea, stomachache and diarrhea.

The toxic ingredients of fresh cauliflower will be weakened at a high temperature of 60 ℃. When eating, you can blanch water first, then soak it in clean water for more than 2 hours, then fish it out for stir-frying; dried cauliflower can be soaked in warm water for many times, and then fried for consumption.

Although these vegetables are delicious, they all belong to high-risk food. You must make clear the taboos before eating, or you will feel the pain if you eat into your stomach.
