Tanida Dream (more balanced nutrition, recognize Tanida Dream) Answer:

Walnuts are versatile. Walnut trees are tall, tall and graceful, with lush branches and foliage, and can live for decades to hundreds of years. Walnut leaves can emit a fragrant scent, have a strong ability to intercept soot, absorb sulfur dioxide and purify the air.

Walnut wood has a light and elegant color, beautiful pattern, fine and tough texture, no warping and no cracking, and is an excellent material for manufacturing high-end furniture and military timber. Walnut has a well-developed root system, deep and wide distribution, which can play a role in consolidating the soil and reducing surface runoff, and is a good tree species for greening, beautification and soil and water conservation. The green skin and branches and leaves of walnut fruit contain a large amount of tannin substances, which can be used to extract tannin gum and used in the dyes, tanning, and textile industries.

Walnut shells can be used to make high-grade activated carbon, which is an important chemical raw material. It can be seen that the walnut tree is full of treasures.

Walnuts are the first of the world's four major dried fruits (walnuts, cashews, hazelnuts, and almonds). Walnut kernels are nutritious and delicious. It was determined:

The oil content of walnut kernel is higher than that of soybean, peanut and rapeseed. The crude protein content is generally about 15%, up to 15%, higher than the content of eggs and duck eggs, twice that of tofu and 5 times that of fresh milk. Walnut kernels are also rich in vitamins and calcium, magnesium, iron, phosphorus, zinc and other inorganic salts that are beneficial to the human body, and also contain 18 kinds of amino acids, of which there are as many as 8 kinds necessary for the human body.

Aksu's dried walnuts almost monopolize the Chinese market, and you say whose walnuts are the best. In addition to the competition between Yunnan walnut and Xinjiang walnut, there are Aksu walnuts in major cities in China, and it is the highest. Yunnan walnuts, Hebei walnuts, and walnuts in the north and south of the Qinling Mountains in the Qinling Mountains have their own flavors.

Because it is wild-grown, it looks ugly and sells poorly, but walnut kernels contain many unsaturated fatty acids and have great nutritional value. Yunnan walnut production first, Shanxi second, Shaanxi third, in fact, the taste is not bad, the main thing is that everyone's appetite is different, in fact, the appetite is the same, ** is different.

Walnut kernels are warm and sweet, enter the kidney, lungs and large intestine meridians, have the function of tonifying the kidneys and warming the lungs, moistening the intestines and laxative. It is mostly used for kidney yang deficiency, deficiency and asthma, intestinal dryness and constipation. There is a folk saying that it resembles a brain, called "brain tonic medicine", and in recent years, there are many suspicions of exaggerating its role and misleading consumption.

The main production areas of walnuts are Xinjiang, Hebei and Shaanxi, among which Xinjiang Hotan is the main production area of walnuts, that is, the walnuts produced are relatively good.

China is the origin of walnuts, Yunnan walnut production is the first in the country, Shanxi is second, Shaanxi is third, Sichuan, Hebei, Gansu, Shandong in order. Walnuts are a traditional export from China. The walnuts produced in China's major producing areas have their own characteristics, and there is no such thing as the best.

To tell the truth, the low-quality walnut kernels belong to the mountainous areas in the south of Jinan, the fresh taste is positive, and the Xinjiang walnut kernels bought from the market after being eaten in Beijing are moldy and smell unwilling. **Almost 33 yuan from Jinan.

China's walnut kernel extraction still follows the manual smashing method. In order to improve the kernel rate and export commodity grade, when hand-smashing the kernel, it is necessary to pay attention to the position of the fruit, according to the difference in the strength of the nut in three directions and the structure of the kernel, the suture line is selected and placed equally on the ground, according to the Chinese archaeologists Cishan cultural site found carbide walnut "Walnut Fossil" which confirms that China is the birthplace of walnut, and has since rewritten the origin history of walnut, and confirmed that it has been planted in the southern part of Hebei as early as 7000 years ago.

Walnut is widely distributed in China, north to Heilongjiang, south to Yunnan, Guizhou, west to Xinjiang, east to Shandong, Liaoning, most of the country has walnut distribution. As for the distribution of walnuts that meet the cultural standards, they are mainly produced in North China, Northwest China, Northeast China and Southwest China. Among them, the quality of walnuts in Beijing, Hebei, Tianjin, Shanxi and other places is the most prominent, and it is also the origin of traditional excellent varieties.

The climate and environment are also conducive to the planting and growth of walnuts.

It is mainly produced in North China, Southwest China, Central China, South China, East China, Xinjiang, South and Northwest, and there are still many production areas, and most of them grow on the slopes of mountains between 400 and 1800 meters above sea level.

There are many main producing areas of walnuts, such as Beijing, Yunnan, Guizhou, Xijiang, Shandong, Liaoning, Hebei, Tianjin, Shanxi and so on.

The general production area of walnuts is in Yunnan, because Yunnan is the largest walnut producing area in China, and the climate and temperature in Yunnan are also very suitable for the growth of walnuts.

1. Reduce the risk of cardiovascular disease.

A study published in the Journal of the American College of Cardiology conducted a controlled trial on 634 volunteers, adding about 2 walnuts per day to the diet of one group of volunteers, and through a 2-year follow-up study, it was found that the weight of volunteers who ate walnuts every day had six inflammatory factors compared with the other group, which was significantly reduced, and these inflammatory factors were mostly related to cardiovascular and cerebrovascular diseases.

Similarly, a study published by Harvard, which analyzed nearly 100,000 people with an average age of 63 years through a 20-year follow-up, found that people who ate about two walnuts a day had a 25% reduction in cardiovascular disease mortality.

2. Anti-aging.

Walnut is a plant of the genus Walnut, and there are two main types of common walnut and iron walnut for economic cultivation. The varieties cultivated in the north and south of our country are specialized.

Most of them belong to common walnuts. Iron walnut, also known as Yangbi walnut, is mainly distributed in Yunnan, Sichuan and Guizhou, this species likes dampness and heat but does not tolerate cold, and is another ecological type different from ordinary walnut. In addition, there are wild walnut and wild walnut, all of which are plants of the same genus.

It is worth mentioning that another genus of the same walnut family - pecans also have a kind of fruit tree that produces nuts, called thin-shelled pecans, also known as American pecans or long pecans, which were introduced into China at the end of the 19th century, and are currently sporadically cultivated in Jiangsu, Zhejiang, Fujian, Jiangxi and other provinces. It likes to be warm and moist, the nuts are large, oblong, the shell is thin and the kernels are large, and the taste is beautiful and of high quality. It has considerable development value in the Yangtze River basin and its southern areas.

Walnuts have traditionally been propagated by seeds, and most of the production is endemic solid types, and there are very few varieties formed by asexual propagation. According to the early and late fruiting and the thickness of the kernel shell, walnuts can be divided into two groups: early walnut (fruiting 2 4 years after sowing) and late fruiting walnut (fruiting 5 10 years after sowing).
