Lactose contained in milk is a disaccharide. Because the molecule is too large, it must be digested into smaller glucose and galactose in the small intestine before it can enter the blood vessels through the intestinal wall and be absorbed. However, when lactase in the small intestine fails, lactose will ferment in the large intestine, and symptoms such as flatulence, abdominal pain, vomiting or diarrhea will appear within about half an hour to two hours.
Lactose intolerance is a very common phenomenon, especially the incidence of lactase deficiency in Asians is as high as 90%. According to the survey conducted by the Institute of Nutrition and Food Safety of the Chinese Center for Disease Control in Beijing, Shanghai, Guangzhou and Kazakhstan, the incidence of lactose intolerance was 32.3% for children aged 7-8, and 29% for children aged 1 1 ~ 13.
Soymilk is a traditional drink in China, and people in China have had the habit of drinking it for a long time. However, as we accept western culture, drinking milk is accepted by China people. Many people think that milk is more nutritious, so the number of people drinking milk is increasing gradually.
In fact, according to the constitution of China people, drinking soybean milk is more beneficial than drinking milk. Milk contains lactose, and two-thirds of people in the world do not absorb lactose. In Asia, 70% of yellow people do not absorb lactose. We are yellow. Some people drink milk but don't absorb much. White people absorb the most milk.
A survey in Beijing shows that 40% people do not absorb lactose. Guangdong is the best place to absorb the results of the national census.
What are the advantages of soybean milk? Soybean milk contains oligosaccharides, 100% absorbed. And from the adaptability, more than 40% people in China will have mild diarrhea when drinking milk, but not when drinking soybean milk.
