White sugar is different from brown sugar with ethnic characteristics. Brown sugar contains about 95% sucrose, and its color is dark yellow to reddish brown. Made by the traditional craft of China, it is now produced in Zhejiang, Guangxi, Yunnan, Guizhou and other places. Brown sugar is circulated in ancient Chinese medicine books. The article "Sugarcane" in the newly revised Materia Medica of the Tang Dynasty has the following description: "... taking the law as sugar is very beneficial to people"; In A.D. 1596, it was recorded in Compendium of Materia Medica written by Li Shizhen that granulated sugar "regulates the spleen and soothes the liver" and "tonifies the blood and promotes blood circulation, removes blood stasis and discharges lochia". Data show that one kilogram of brown sugar contains 900 mg of calcium and 100 mg of iron, which is an essential mineral and trace element for human body. At the national nutrition conference in 2000, the author reported the related research results-determined by atomic fluorescence spectrometer, it was found that brown sugar is rich in trace elements, some of which have a strong stimulating effect on hematopoiesis. Traditional Chinese medicine believes that women's postpartum blood stasis and empty eight veins will cause abdominal pain every time. Doctors often prescribe Shenghua Decoction, Stone Dissipation or Jinlingzi Powder to some patients with blood stasis, and instruct them to take it with brown sugar after decoction, so as to achieve the purpose of relieving pain by using the function of brown sugar to "dredge blood stasis" or "expel lochia". For those who can't afford medicine or can't prepare medicine, taking a proper amount of urine mixed with brown sugar for middle-aged children can achieve the same effect. "Women can't be sugar-free for a hundred days" refers to brown sugar. There was once a young woman who was thin and weighed less than 50 kilograms because of long-term illness. After she got pregnant, she had a heavy mental burden and worried that she couldn't bear it. After adopting the traditional dietotherapy method in China, she designed a kind of "food tonic" to warm up deficiency and cold: she was given food such as lying eggs made of glutinous rice wine, brown sugar, sesame and millet porridge. As a result, she not only gave birth to a healthy baby, but also became stronger and healthier than before. She insisted on breastfeeding after delivery, and the baby developed well, lively and healthy. Traditional Chinese medicine nutrition believes that warm brown sugar plays a role in enriching blood by "warming up, warming up and dispersing". Relatively speaking, although sugar tastes sweet, it is white in color and flat in nature, and its blood-enriching effect is far less than that of brown sugar. According to our analysis results, because white sugar is too pure and contains almost no trace elements, its nutritional efficacy is naturally different from that of brown sugar. Even in Japan with advanced technology, many foods are specially marked with the words "pure brown sugar", which shows from one side that brown sugar and white sugar are not the same thing, so families and canteens should always keep brown sugar. In daily life, you can also make the following dietary prescriptions for health care: jujube tea: jujube 10, boiled in water, added with brown sugar, mixed with black tea water, and taken once, which has the functions of invigorating qi and blood, invigorating spleen and stomach.

Chinese medicine believes that brown sugar is warm, sweet and enters the spleen, which has the functions of invigorating qi and enriching blood, invigorating spleen and warming stomach, relieving pain, promoting blood circulation and removing blood stasis. The intake of trace elements and vitamins in the elderly is gradually decreasing, so attention should be paid to supplementing them in the diet to maintain normal metabolic function and delay aging. Therefore, experts suggest that the elderly should choose more brown sugar when eating sugar. Old people in Japan's famous Changshou Prefecture and Okinawa Prefecture have the habit of drinking a cup of brown sugar water every day. However, not all elderly people are suitable for eating brown sugar. Chinese medicine believes that people with yin deficiency and internal heat, indigestion and diabetes should not eat brown sugar.
