Autumn is the season of yam harvesting, and since ancient times, yam has been regarded as a "tonic" with good quality and low price, and it is also known as the "first supplement in autumn".

Although this "long-haired mud stick" dug out of the soil looks unassuming, those who really understand it will understand its goodness. Yam is rich in nutrients, in addition to containing a variety of vitamins and minerals, but also contains amylase, polyphenol oxidase and other health-promoting ingredients.
On top of that, it's a versatile, zero-based, delicious ingredient. For example, stir-fried yam broccoli, corn yam lily soup, assorted yam granules, yam tofu soup, yam multicolored shrimp, seaweed yam rolls; and a series of desserts, coconut steamed yam, orange peel yam balls, blueberry yam puree, jujube mud yam cake, silk yam.......
With 1 kind of yam, you can make 100 kinds of non-repetitive eating methods!
The taste of the cooked yam is dense and sweet, but when the yam is treated, it is often hurt by its "small temper", cutting a yam skin, itching hands, redness and swelling and allergies... Special fuss!
Why do peeling yam skins itchy hands?
Yam contains saponin, which produces mucus during peeling, and the proteins in the mucus and diosgenins irritate the skin, resulting in "itchy" symptoms.
People with sensitive skin may also have redness, swelling, tingling, and in severe cases, they may even cause contact dermatitis.
Yam peeling non-stick and non-itchy!
A chopstick to remove the yam skin:
Chopsticks are inserted directly into the yam, and then the yam is peeled with a knife, which can avoid contact between the yam and the skin, and you are not afraid of irritating the arm and itching.
The yam is blanched before it is peeled:
Boil a pot of boiling water, pour it into the basin where the yam is placed, and then peel it after the water is cool, so as not to itch your hands!
Boiling water scalded yam, thin yam skin is basically cooked, slippery mucus is also solidified, the original allergen is destroyed, and there will be no allergy when exposed to it.
If you get your hand with yam mucus and you have an itchy feeling in your hand, you must not scratch it with your hands, scratching may make the itch more severe, and it will also cause redness, swelling and tingling in your hands. Therefore, before peeling, it is necessary to take effective methods in time to alleviate it.
After the yam is peeled, soak it in water or it will turn black.
Shaved yams turn black, mainly because the phenols in the yam are oxidized after contact with the air, forming quinones with color. Therefore, the phenomenon of blackening and browning will occur.
This situation does not belong to the scope of deterioration, it is only a change in color, so the yam that turns black after shaving can also be eaten. However, if the flesh of the yam has not yet turned black, it may be caused by mildew, and the yam in this situation has deteriorated.
Is it good to buy a yam coarse or fine?
The quality of yam mainly depends on the variety, the nutritional price and the variety are very different, do not look at the appearance.
There are two main types of yam on the market, one is ordinary yam and the other is iron stick yam.
Ordinary yam is commonly known as vegetable yam, mainly used in dishes, general nutritional value, the taste is crisp. So for the same kind of vegetable yam, of course, it is coarse and good.
Iron stick yam is different from vegetable yam, and it is smaller and shorter than vegetable yam. But it is rich in nutrients, fleshy porcelain, and has a good taste. In the iron stick mountain medicine species, of course, it is also coarse and good.
Therefore, when buying yam, the most important thing is to buy the right variety, and in this variety, it is better to pick the largest than the small.
Yam is generally edible to everyone, and Chinese medicine believes that yam is sweet, flat, not dry and not greasy, and enters the lungs, spleen and kidney meridians. But these people can't take yams.
1. People with constipation
Yam is rich in starch, it is best to eat less for people with full chest and abdomen, dry stools, and constipation, and can eat yam after these symptoms are relieved.
2. Diabetics should not eat more
Although it is said that yam contains mucus protein, which has the effect of lowering blood sugar, yam is a rhizome food, the amount of starch is high, if too much consumption will not reduce blood sugar, but will lead to blood sugar rise.
Therefore, people with diabetes should not take too much yam at a time, and if some patients prefer to eat yam, then the amount of staple food should be appropriately reduced, otherwise it will be counterproductive.
