Fruits and vegetables are rich in nutrients and delicious. They are the first choice for many people whether it is dinner or leisure time.
However, eating fruits and vegetables is also entangled: how to deal with the skin, whether to throw it or eat it? "Eat grapes without spitting out grape skins" is not just a tongue twister, it also expresses the medicinal and health value of fruit skins.
However, in common sense, everyone thinks that eating fruit requires peeling. Apple peels, banana peels, Sydney peels, etc. are all discarded by us. Some people think that most of the nutrients in fruits are in the skin, which is a pity to throw them away.
Recently, there has been a saying on the Internet that "fruit and vegetable peels cannot be eaten, otherwise they will be poisoned."
"You can't eat fruit and vegetable skins, otherwise it will be poisoned", is it really reliable? Is it no longer possible to eat "skin" anymore? Today, Xiaosu and everyone will talk about food and drink.
01
Whether the fruit should be peeled and eaten
It is reasonable that the national standard has strict regulations for the use of pesticides. safe. But Xiaosu knows that some people feel uneasy, and WHO thinks so too, so in 2015, he gave a recommendation for China: Root vegetables and fruits should be peeled.
Even though this is the case, don’t worry too much, just like the following two situations:

But the wax on apples is different from floor wax : most of the wax is the natural fruit wax that comes with apple , which is used to prevent insects and bacteria, and it will do no harm if you eat it. ;
The other is to preserve freshness and preservative during storage. Food grade fruit wax applied in advance is not harmful. This steak is mainly to give a reason to be lazy. I really don’t bother to peel it, so it’s okay to eat it directly.

Hoar frost on grape skins
There are rumors that hoar frost on grapes must be washed off.
But in fact, people obviously secrete sugar alcohol ,It can also be regarded as a kind of wax, which prevents the evaporation of water while also resisting the infection of germs.
is not harmful to humans, it is difficult to wash off even if you want to wash it, but rubbing the grapes will soften the grapes.
Moreover, if after a series of tossing, storage, and transportation, the hoarfrost has not been wiped off when it reaches you, which just proves the freshness of the grapes.
So, when you encounter small grapes with hoarfrost, you can simply soak them and brew them and eat them. It depends on your mood. Compete.

Therefore, if it is cleaned, it is better to eat apples with skin.

How to deal with pesticide residues?
I believe most people just rinse with water like Xiaosu.
Research shows that washing agricultural products with clean water can reduce the residual amount of 9 kinds of pesticides in 12 kinds of pesticides. And most detergents are not better than water.
Salt water is one of the easiest and most cost-effective methods to remove certain pesticides. Some researchers use vinegar, saline solution and ordinary water to wash fruits and vegetables for 20 minutes to eliminate the residues of four common pesticides. The results show that the effect of 10% saline solution is the best, far surpassing clear water.
The most effective way to clean fruits and vegetables is actually baking soda ,Studies have shown that it can effectively remove pesticide residues on the surface of the peel. Soak fruits and vegetables in a 1% baking soda solution for 12-15 minutes to completely remove pesticide residues.
For peeled fruit, clean the skin and knives before peeling, otherwise dirt and bacteria will be transferred from the knives to the fruit.
Before soaking the fruit, make sure that the skin is intact, otherwise the pesticide will be immersed in the pulp.
After washing the fruits, pat them dry with clean kitchen paper or paper towels to further reduce possible bacteria.
Many people are accustomed to washing and storing fruit in the refrigerator after buying it home, but doing so will increase the moisture content of the fruit and increase the risk of microorganisms. Therefore is best to wash the fruit before eating.
