Brook Steamed Chestnuts healthy
Chestnut is native to China and is distributed in both north and south regions. The chestnuts in Pingle County, Guilin City are very famous and are known as the "Three Treasures of Pingle" together with ginkgo and green plums. Traditional Chinese medicine believes that chestnut is the "fruit of the kidneys" and has a very good effect on nourishing the kidneys and stomach. Modern nutritional analysis shows that chestnuts contain a large amount of starch and sugar, as well as some protein, fat and various vitamins, and are known as the "King of Fruits".
There are many ways to eat chestnuts, and there is a folk saying that eating chestnuts raw can nourish the kidneys. Of course, most people still eat it cooked. Chestnut roasted chicken is one of the home-cooked dishes. You can often see the attractive aroma of sugar-fried chestnuts on the street. Affiliated to Guilin Medical College Hospital clinical Zuo Zheng, a nutritionist in the Department of Nutrition, said that as for chestnuts in Guilin, it is healthier to eat them steamed.
It turns out that there are differences between north and south chestnuts. The chestnuts in the north are waxy and suitable for stir-frying, while the chestnuts in the south are japonica and suitable for making dishes with other foods. Since a low-oil, low-salt diet is healthier, it is better to steam chestnuts or boil them into soup.
Eat raw chestnuts to strengthen your body and strengthen your bones
Although chestnuts are rich in nutrients and have the therapeutic effect of nourishing the kidneys and strengthening the body, they should not be eaten in excess. “Chestnuts are difficult to digest when eaten raw, and can easily stagnate when eaten cooked, so don't eat too much. ”Zuo Zheng said. Chestnut has a high starch content, which is good for the elderly and those with poor digestive function. Child It is best to eat less. After the chestnuts are cooled, the starch will age and become more difficult to absorb, so eat chestnuts while they are hot as much as possible. In addition, people with diabetes, constipate Patients and pregnant women should not eat more chestnuts.
Su Che, a writer in the Northern Song Dynasty, once wrote in a poem: "Old age makes me suffer from waist and foot problems. The mountain old man takes the old prescription of Li. When a guest comes, he wakes up late in the morning and swallows the white jade pulp slowly after three swallows." ”This means that eating raw chestnuts can strengthen the body and bones and relieve pain in the waist and legs. If it is eaten raw, people with weak spleen and stomach cannot eat it. Others should chew it carefully and swallow it slowly, that is, "Three swallows slowly to collect the white jade pulp".
Stir-fried chestnuts with sugar, beware of paraffin
Zuo Zheng said that ordinary sugar-fried chestnuts add oil and sugar, which will have higher calories, but it does not pose many health hazards. However, some vendors add industrial paraffin when frying chestnuts, so that the fried chestnuts are very bright and look better. This kind of chestnut is quite harmful to the human body. When paraffin accumulates in the human body to a certain extent, it will have adverse effects on the respiratory tract, leading to pneumonia, tracheitis, etc. disease。
Therefore, we should be more careful when buying sugar-fried chestnuts. If the surface is too shiny, there may be problems. Normal sugar-fried chestnuts will have the sugar caramelized and stuck to the shell, making them sticky to the touch. However, those fried with paraffin will have a smooth appearance. Paraffin wax is insoluble in water. If paraffin wax is added, floating matter will appear when soaked in water. At the same time, when eating chestnuts, try to break the chestnut shells with your hands instead of biting them with your mouth.

Nutritional value:
Chicken meat is tender and delicious. Because of its light taste, it can be used in various dishes. Chicken contains a lot of protein. Among meats, it can be said to be one of the meats with the highest protein. It is a high-protein and low-fat food. The content of potassium sulfate amino acid is also very rich, so it can make up for the deficiency of beef and pork. At the same time, chicken has more vitamin A than other meats. Although it is inferior to vegetables or liver in terms of quantity, its vitamin A content is much higher than beef and pork. Chestnuts not only contain a large amount of starch, but also contain protein, vitamins and other signature nutrients. They are known as the "King of Dried Fruits". Chestnuts can be used as a food substitute. Together with dates and persimmons, they are called "hardcore crops" and "woody grains." They are a cheap, high-quality, nutritious tonic and nourishing vegetable.
Chestnuts are delicious, but they are difficult to store because chestnut fruits have the characteristics of "four fears": dryness, water, heat, and freezing during storage. If you are not careful during the storage process, they will become moldy and deteriorate.
1. Choose storage-resistant varieties. Generally, mid- and late-maturing chestnut varieties are more resistant to storage. In fact, northern varieties are more resistant to storage than southern varieties.
2. Harvest at the right time. The maturity of chestnuts varies depending on the place of origin and variety. Generally, it is appropriate to harvest when they are fully mature. In addition, you should also pay attention to the weather when harvesting. Do not harvest on rainy days or when it clears up after a rain and the dew has dried. Harvesting prematurely or harvesting immature chestnut fruits by breaking the chestnut buds at one time will not only affect the increase in the weight of the chestnut fruit and the quality of the chestnut fruit, but also cannot withstand storage.
3. Prevent and control pests and diseases. After mechanical damage to chestnut fruits and damage from chestnut pests such as weevils and peach borer, chestnuts are extremely susceptible to infection by pathogens. Therefore, it is necessary to strengthen the prevention and control of chestnut pests before harvesting. During storage and transportation, care should be taken to pack and handle with care to prevent mechanical damage. At the same time, disease prevention treatment before storage should be carried out. For example, use "carbon disulfide" fumigation to kill insects. Soaking the fruits with 500 times of thiophanate or 1000 times of Tekodos for three minutes is effective in preventing and controlling pathogens, but it should be done within 1-2 days after picking the fruits.
4. Selection. Use 10% salt water to select chestnuts to eliminate diseased and insect-infested chestnuts and immature hollow and shriveled grains, which is beneficial to the storage and preservation of chestnuts.
5. Pre-storage. Spread the harvested chestnuts in a cool and dry place to dry. A weight loss rate of about 8% is appropriate. Weight loss rates below 5% or above 12% will affect the storage effect.
