Is the walnut really replenishing the brain? How much do you know about walnuts? Experts from the Institute of Economics and Crops of Shanxi Agricultural University answered you.

To make up for shape? not enough

Walnuts are very similar to micro -"brain". Do you really make up the brain to eat more walnuts? Walnuts do contain some substances that are beneficial to the development of the brain, but it is not enough to achieve the so -called "complementing shape" effect. The role of food nutrition is the effect of long -term accumulation. After the unsaturated fatty acids in walnuts are absorbed, they will be transported to the brain to participate in the brain membrane. This is a long -term metabolic process. Besides, the fat content in walnuts is also high. Eating 3-5 walnuts a day is the most suitable.

Originally known as Walnut originated from 起hu

Experts explained that walnuts were originally known as walnuts, and "Famous Doctors' Records" recorded: "This fruit comes from Qianghu, Zhang Jian made an envoy in the Western Regions in the Han Dynasty. South Asia, Eastern Europe and Xinjiang Gansu and Ningxia in China. When Zhang Jian introduced the walnut into the Central Plains region, it was called the walnut. Historical records that in 319 AD, Shile, the leader of the Caacea in the Sixteen Kingdoms of the Eastern Jin Dynasty, occupied the Central Plains and Zhao after the establishment. Because of its taboos, it was renamed Walnut to walnut. This name continues to this day.

86%of the fat in walnuts are unsaturated fatty acids, rich in copper, magnesium, potassium, vitamin B6, folic acid and vitamin B1, and also contain fibrous, phosphorus, tobaccoic acid, iron, vitamin B2 and pantothenic acid. Of every 50 grams of walnuts, moisture accounts for 3.6%, which contains 7.2 grams of protein, 31 grams of fat and 9.2 grams of carbohydrates.

The value of walnut medicine is very high, and it is widely used in Chinese medicine.

In the 1970s, my country's walnut trade accounted for 70%of the world's trade. Later, due to the rapid development of Western breeding, my country's walnut international trade has shrunk rapidly. In 2022, the Institute of Economics and Crops of Shanxi Agricultural University aimed at the international trade market, and cultivated the new variety of large fruit, high -quality, and flavored walnuts, "Fen Nuclear No. 1", and won the second prize of scientific and technological progress in Shanxi Province in 2022.
