The reason why Ke Jiquan can't eat sugar well is that Ke Jiquan's digestive system can't secrete and decompose disaccharides (such as sucrose), so it can't decompose and absorb sucrose. Once a large amount of sucrose or fructose is ingested, a hypertonic environment will be formed in the digestive tract, so that a large amount of body fluids will enter the intestinal cavity, which will lead to diarrhea. Once diarrhea, the body quickly dehydrates and the resistance drops. Intestinal flora, pathogenic bacteria and viruses take advantage of the situation and multiply rapidly, leading to gastroenteritis.
