They are often called "vegetables on the tree" because they grow on the treetops.
Many people are deeply enamored with its unique taste, and the price has risen

Toon is so expensive, is there any special nutrition? Talk about toon today

Toon is so expensive, what nutrition does it have?
Toon is so expensive, what nutrition does it have?
Toon is also known as toon bud, toon pile head, big red toon tree and so on
.
The special taste of toon comes from its special volatiles, including terpenoids and sesquiterpenoids
.
It is precisely because of this special fragrance that people who like toon will eat toon every spring, and those who don't like it will avoid it

Toon is sold so expensive, does it have any special nutrition?
Toon is regarded as a vegetable with quite good nutritional value
.
Toon is rich in potassium, calcium, and magnesium, and the content of vitamin B group is also among the best in vegetables
.
Some studies have also found that toon is helpful for preventing chronic diseases.
It contains ingredients that inhibit a variety of pathogenic bacteria, as well as rich polyphenolic antioxidant ingredients

However, it is nothing special
.
I have seen a lot of articles saying that toona sinensis has various health-care effects.
What is anti-tumor, lowering blood fat, lowering blood sugar, etc.
, this is an exaggeration
.
In fact, toon does not have that magical effect, it is just a seasonal vegetable with a unique taste
.
I eat it a few times a year in the spring, and I don’t eat much each time, so I can’t talk about any special effects

Toon is delicious, but danger lurks
Toon is delicious, but danger lurks
Although delicious toon always makes people who love it willing to empty their wallets, did you know that there is often a dangerous molecule-nitrite lurking in delicious toon
.
.
Why is there nitrite in toon? We know that nitrogen fertilizer is needed when plants grow
.
Nitrogen is a widespread element in nature.
Plants absorb nitrogen in the environment and finally synthesize amino acids through complex biochemical reactions
.
In this process, the production of nitrate is an inevitable step
.
There are also some reductases in plants, which reduce part of nitrate to nitrite
.
In fact, all plants contain nitrate and nitrite
.
Nitrite is toxic
.
Toxicological analysis shows that nitrite has a certain acute toxicity, and its half-lethal dose for dental caries is 57 mg/kg
.
Moreover, it also increases the risk of cancer, because nitrite and protein decomposition products react under acidic conditions to easily produce nitrosamines, and nitrosamines are recognized as carcinogens

Although the content of nitrite in most toon is not harmful, the nitrite in some toon is sometimes directly measured in grams/kg.
There have been cases of nitrite poisoning caused by accidental eating of toon

Before eating toon, use boiling water
Before eating toon, use boiling water
The good news is that before eating toon, you can remove most of the nitrite by blanching it with hot water
.
.
For example, studies have shown that when blanching toona sinensis, about 80% of nitrite can be removed in 30 seconds, and 83.
86% of nitrite can be removed in 45 seconds
.
Therefore, when eating toon, be sure to blanch it in boiling water for 30-40 seconds

In addition, I also remind everyone that when choosing toon, try to choose the tender shoots and eat them when they are freshest, because the toon shoots contain less nitrate and nitrite
