Three benefits of eating pears in autumn

When it comes to autumn fruits, the first thing that thinks of is pear, which has the characteristics of high moisture, low calories, low GI, high fiber, and phenol -rich substances. Small below. Pear is the fruit of the Rosaceae family. It has a close relationship with Apple. It is also similar to Apple in terms of nutrition and health effects.

The nutritional advantage of pear

Pears are really average in vitamin C (about 5-10 mg/100 grams) and potassium (about 50-150 mg/100 grams), magnesium (5-11 mg/100 grams).

Pear has its own advantages in the following aspects:

High moisture, low calorie, low GI. Pear water content can reach more than 90%, about 35-50 kcal per 100 grams, and it belongs to the hypoglycemia index fruit (blood glucose index 33). People who control blood sugar can also be eaten in moderation.

High fiber. Pear rich contains dietary fiber and can reach 6%, and some varieties can even reach 9%, especially for insoluble fibers (71%of pear dietary fibers are insoluble fibers, and 29%are soluble fibers). In fact, you can feel the feeling of hard residue when eating pears. This is a structure called "stone cell" unique to pear fruit. Stone cells are formed by the cell wall of ordinary thin -walled cells and the disappearance of cytoplasm. The main component is lignin, which is a type of insoluble dietary fiber.

Rich in phenolic substances, easy to use and storage. Pear contains rich phenolic substances such as chloric acid, catechin, coffee, non -eaten meal, coffee acid, coffee acid, coffin, coffeein, schoa acid, sodic acid, and original flower greenin. In fact, many fruits are rich in phenol -containing substances, but phenolic substances are often combined with other plant components, and they need to be metabolized or released by the intestine to produce health benefits. The special feature of pear is that it is rich in methyl -based phenolic acid, which is more likely to be directly metabolized. 70%of the phenolic acid in pear is methylated, and in other fruits, this ratio is usually less than 23%. Due to antioxidant phenols, pear extracts show a good anti -inflammatory effect in animal experiments. The phenol content in pear skin is higher than the flesh, and peeling can cause the total phenolic material content to decrease by 25%.

In addition, pears are more resistant to storage. Studies have found that under good storage conditions, the antioxidant performance of pear can remain up to 8 months.

The yellow skin is good or green

There are many types of pears. There are 4 most common in my country: sand pear, white pear, Qiuzi pear and Xinjiang pear.

The Shari is native to Sichuan and is mainly distributed in the Yangtze River Basin and south of it. The pear is mostly green, and there are many specific varieties, with thousands of, such as "Cuiguan" "early beauty crisp" "Emerald", "June Snow", "Yellow Crown", "Yellow Flowers", "Jade Water", "Jade Green" "Hua Pear", such as Qiuyue Pear with brown peels, red peels like Yunnan "Beauty Crisp." The flesh of the sand pear is crispy, but it is relatively rough.

The white pear is native to Hebei, and is mostly distributed in the north. For example, the Yali, Swredan pear in Hebei, Serarton Pear, Shandong's Laei Pear, Anhui Laoshan Crispy Pear, etc. Some scholars believe that it is a hybrid variety of sand pears and Akiko pear. The white pear peel is mostly yellow, with large fruit and few stone cells. Although it is also crispy as sand pear, it is more delicate.

Xinjiang pears are distributed in Xinjiang, Gansu, Qinghai and other places. It may be a hybrid between white pears and western pears. For example, in recent years, the popular Korla Xiang pear, which has been small and exquisite in shape, sweet and delicious. The emotion of its epidermis is different from sand pears and white pears. Some of them are smooth and are distributed by natural pectin and other substances.

Qiuzi Pear is a wild variety in the Northeast region. It is quite cold -resistant and sand resistant, but it is small, with a lot of stone cells, and sour taste. It should not be eaten fresh. Qiuzi pear, which was just taken off, was thick and tight. It was necessary to wait for it to be familiar with it. The process took more than ten days. After being cooked, Akiko Pear becomes soft and juicy, and the strong sour taste is also an advantage for those who like it. Although it should not be eaten fresh, Akiko Pear has the most special way of eating -frozen pear. Eating frozen pears has a long history. Some people ate this in the Song Dynasty. It is a good and delicious way to develop in the cold area of ​​the northwest. After the meeting, the soft autumn pear is the most suitable for frozen pears. It is commonly known as "soft pear" and "soft pear" in the northwest. After the pear is frozen, the peel becomes black like charcoal, and it is difficult to associate with the food. However, after using a bowl of cold water, it becomes very easy to separate the flesh, and the juice is rich. Essence In the cold winter, after a meal, eat a frozen pear next to the dry heat heating room or stove, nourishing and greasy.

Pick pear can look at the bottom

For a lot of fruits, it is pseudo -science to watch "male" and "mother", but it really makes sense in pears. Pear is a "fake" fruit. The fruit of the pear plant is a kind of fake fruit. The reason why it is called fake fruit is because the part of the pear is not like other fruits, but it is developed from the calyx tube and the wall of the child room. Say it is fruit, more like a leaf that has changed.

The bumps at the bottom of the pear are related to quality. Due to this special development method of fake fruits, there are two situations: Su Guiguo (commonly known as male pear) and removing fruit (commonly known as mother pears). Studies have found that pear "take off the fruit" is better than "Su Guiguo", especially for Korla Xiang Pear, the total sugar, sucrose, soluble endopine content, VC content, and solid acid ratio of soluble endogenous pulps are significantly significant Higher than Su Guiguo, simply sweeter and stronger flavor.

The study of 5 kinds of pears, crispy pear, jade crispy pear, red crispy, and Shuofeng pear also found that the content of high soluble solid solids and low -diameter stone cell content is low Essence However, for ordinary consumers, the two fruits may not be distinguished with the naked eye, because for some common varieties, it is not completely corresponding to the bumps at the bottom of the bottom, but it looks like a pear that is protruding at the bottom (Sudden Top fruit) is a high probability of Su Guiguo (91.4%), and pear (concave fruit) depressed at the bottom is a high probability (53.5%) for removal fruit, and the bottom is not impossible to improve through artificial pruning. The relationship between pears and health

Pear is often associated with the respiratory tract and lung health. Studies have shown that the antioxidants such as carotene, flavonoids contained in fruits and vegetables are related to the reduction of the risk of lung cancer, but there is no research on the special advantages of pear. Pear often shows the same effect as Apple and other rosh family fruits.

For example, a study by the American retirement Association found that consumption of Rosaceae fruits (including apples, peaches, oily peaches, plums, and pear) have a certain reduction in the risk of lung cancer. Both edible pears and apples have a certain protective effect on the lungs.

Small below. The content of insoluble dietary fibers in pears is very high, which can not only increase the weight, but also mechanically stimulate the inner wall of the intestine and promote peristalsis. Pear also contains 2.5%sorbitol, which is difficult to digest and love water absorption, which can ferment the intestinal microorganisms and promote ingotic peristalsis. Especially when eating on an empty stomach, the effect is particularly good. In addition, pear also has 4.5%fructose, which also has a laxative effect for people with lack of fructase.
