First of all, let's see, is brown sugar really just sugar and nothing else?
This is actually a paranoid idea. For example, Ejiao is donkey skin, which is no different from pigskin. It only contains protein. It is better to eat pig's trotters than donkey-hide gelatin. Brown sugar contains only sugar and few other ingredients. Eating brown sugar is an IQ tax. This kind of pure nutritional analysis is a bit ignorant. Why eat with such an analysis? Grab yourself a handful of powder and eat it every day. Who would do that? Protein is just a form, and there are more complicated structures and substances. So it can't be explained simply by component analysis.
Brown sugar and sugarcane juice are cooked together. Brown sugar is used in rough machining. When it is roughly processed into brown sugar, it contains protein, fat, calcium, phosphorus, iron, glutamic acid, serine, alanine and vitamins B 1, B2, B6, etc. Therefore, the brown sugar roughly boiled with sugarcane juice not only has the function of sugar, but also contains rich vitamins and trace elements needed by human body. How can you say that sugar is neglected?
Second, since brown sugar is not just sugar, how does brown sugar replenish blood?
Chinese medicine believes that blood can replenish blood as long as it is conducive to blood production and reduces consumption.
For example, blood is transformed from nutrients absorbed by the spleen and stomach, so anything beneficial to the spleen and stomach can directly or indirectly produce blood. But isn't anything that can reduce hard consumption also a blood tonic?
In addition, Chinese medicine's understanding of brown sugar, in addition to enriching blood and nourishing blood, the most important thing is to promote blood circulation and remove blood stasis. Warm brown sugar plays a role in nourishing blood and removing blood stasis through "warming and tonifying it, warming and dredging it, and warming and dispersing it". Modern medical research has confirmed that brown sugar can promote uterine contraction and help discharge blood stasis. In China, brown sugar has always been regarded as a necessary product to discharge lochia. This kind of actual combat experience can't be erased in one sentence.
Brown sugar is warm and sweet, enters the spleen meridian, stomach meridian and liver meridian, and has the functions of invigorating qi and enriching blood, invigorating spleen and warming stomach, relieving pain, promoting blood circulation and removing blood stasis. You can replenish blood, but you can't eat too much or eat indiscriminately. People with deficiency-cold type generally drink a little brown sugar and ginger tea and add ginger. Many people's dysmenorrhea, abdominal pain and chills in hands and feet have improved, but those with yin deficiency and excessive fire are not suitable for drinking.
