Lactase is a digestive enzyme secreted by small intestinal cells and its function is to digest lactose. What about digestive enzyme definition ?Digestive enzyme: a general term for enzymes involved in digestion. The function of digestive enzymes is hydrolysis. Some digestive enzymes are secreted by digestive glands, and some are involved in intracellular digestion. Extracellular digestive enzymes are secreted in the form of Pepsinogen, trypsinogen, carboxypeptidase and other inactive enzymes and then activated. Lactase deficiency causes lactose digestion and absorption disorders, and a series of clinical symptoms such as bloating, abdominal pain and diarrhea are called lactose intolerance.
Lactose intolerance - not only affects life but also causes nutrient deficiency. Lactose is mainly found in milk and its products. The lactose content in milk is about 5%, and the lactose content in breast milk is 7%, except for breastfed infants, all human lactose comes from milk and its products. Therefore, lactose intolerance refers to milk. Lactose intolerance not only affects the absorption of lactose in milk and its products but also causes gastrointestinal discomfort. It can reduce the absorption and utilization of protein, calcium, iron, vitamin B12 and other nutrients in milk and other foods that are ingested at the same time as milk, resulting in a lack of nutrition.
Therefore, finding a simple, safe and effective method to prevent lactose intolerance is of great significance for improving the nutritional status and health of these people. Add lactase - easy to drink milk, improve symptoms of diarrhea.
Recently, we added lactase to 41 lactose intolerant volunteers to understand and observe the therapeutic effect on lactose intolerance. The subjects were 19-79 years old, including 15 males and 26 females. The test method was as follows. Under different conditions, the subjects were given milk 2 times and the results were observed. For the first time, 300 ml of whole milk was given on an empty stomach, no lactase was added. After one week, the same amount and brand of milk were consumed for the second time. A lactase tablet was taken orally 5 minutes before the milk was consumed (milk companion, Lactase 60 mg). The effect of lactase was evaluated using the urinary galactose test method and the lactose intolerance symptom scoring method.
The results showed that all subjects who did not receive lactase before drinking milk were positive or weakly positive for the galactose test, and 28 (68.3%) had symptoms of lactose intolerance, and the severity of symptoms was different. Most of them appear within two hours after drinking milk, which is manifested as abdominal distension, diarrhea, hernia, bowel, and anal exhaust. Among them, 14 (33%) had increased stool frequency and diarrhea.
Symptoms slowly relieve themselves after some time. The longest-lasting until the morning of the second day has a certain impact on life and health. Then, before the second drinking after one week, 41 lactose intolerants were supplemented with 1 piece of lactase. After that, 36 people had urinary galactosidase from positive to negative, and 4 were urinary galactosidase. From positive to weak positive. The total effective rate was 97.6%.
The experiment showed that after lactase supplementation, all people had complete disappearance of lactose intolerance within 2 hours, but 3 people still had mild symptoms of lactose intolerance within 2-24 hours. The reason may be that these people are seriously deficient in lactase, and lactase 60 mg is not enough to completely decompose lactose in 300 ml of whole milk. It is concluded that if lactose intolerance is severe, oral lactase should be appropriately increased. The dose, or reduce the amount of milk (about 200 ml each time).
In the trial, no lactase was found to be caused by any side effects. Lactose intolerant can take lactase preparation before or during drinking, which can directly help lactose digestion and absorption, prevent lactose intolerance, and improve the absorption of protein, calcium, phosphorus and other nutrients in milk. Utilization is a simple, effective and safe method of prevention and control.
