Title: Composition for Treating Diarrhea

Description:
TECHNICAL FIELD 
     The invention relates to a food composition for treating diarrhea, belonging to the food field. 
     BACKGROUND ART 
       Colocasia esculenta , also known as taro or Chinese eddo, is the underground bulb of araceae plants. Its shape and succulent vary from species to variety. The usually eaten species is small taro. Since taro contains a lot of dietary fiber, it also has a good laxative effect. 
     Some fruits and vegetables are rich in cellulose, which are also conducive to laxative; some fruits and vegetables contain a lot of sugars, which can form a hypertonic environment in the intestinal tract, which will further increase the water in the intestinal tract and aggravate diarrhea. 
     Cereals are rich in protein, starch and cellulose, and many of them are used for laxatives in daily life. 
     The above-mentioned raw materials are all daily food materials, and many of them belong to the medicine and food homologous substances. If these common ingredients are used to prepare drugs for treating diarrhea, side effects and adverse reactions will be greatly reduced, which is particularly important for infants and elderly patients. 
     Most infants and young children are weak or have other problems, and are prone to constipation and diarrhea. Clinically, medications for these groups are very cautious. At present, the clinical treatment of diarrhea for these groups has problems such as few types of drugs and high drug toxicity. The “Chinese Children&#39;s Clinical Practice Guidelines for Acute Infectious Diarrhea” clarified that eating early can improve the intestinal osmotic pressure caused by infection, shorten the course of diarrhea, and improve the nutritional status of children; a lactose-free diet can shorten the course of diarrhea in children with acute diarrhea. However, the Guidelines do not clearly indicate which foods to eat during diarrhea in children to help the intestinal recovery. Therefore, it is necessary to develop a safe and effective food for the treatment of infants and young children&#39;s diarrhea, through diet therapy, to achieve the purpose of alleviating diarrhea and supplementing nutrition to meet clinical needs. 
     CN201810909369.2 discloses a composition for regulating infant diarrhea. The composition has a good antidiarrheal effect on common infant infectious diarrhea, drug-induced diarrhea and food intolerance diarrhea, but has a poor effect on persisting diarrhea caused by severe milk protein allergy, lactose intolerance and inflammatory bowel disease (IBD). The effects of different formulas are quite different. Therefore, it is necessary to further optimize or design a new formula to solve the above problems. 
     CN108904653A discloses a pharmaceutical composition and uses thereof, which is composed of taro together with fruits and vegetables in a certain ratio. The composition has corresponding definitions on fruits and vegetables, but because part of the defined fruits and vegetables components are high-fiber plants, and it has been proved by practice that some raw materials have a diarrheal effect on infants and young children. Long-term consumption of the aforementioned foods, such as Chinese cabbage and radishes, during infants and young children&#39;s diarrhea, can aggravate diarrhea. Therefore, the components in the composition disclosed in CN108904653A have flawed technical defect that the antidiarrheal effect is unstable. 
     There is currently no safe and stable food for children on the market. Therefore, it is an urgent problem to develop a safe and effective antidiarrheal diet for infants and young children with safe food material as components. 
     SUMMARY OF THE INVENTION 
     The object of the present invention is to provide a dietary composition for treating diarrhea. The dietary composition uses common food materials as raw materials to achieve the purpose of antidiarrheal based on reasonable matching, which is safe and does not have side effects, so as to satisfy the need of antidiarrheal of frail people, such as infants and children as well as the patients with radiotherapy and chemotherapy. 
     Another object of the present invention is to provide a composition for treating diarrhea in infants with milk protein allergy, which can help infants with milk protein allergy to quickly solve the problem of supplementary food. 
     Another object of the present invention is to provide a composition for the treatment of persistent diarrhea caused by lactose intolerance and milk protein allergy, which can quickly and safely improve the symptoms of chronic diarrhea.

     Test Example 
     EXPERIMENTAL EXAMPLE 1 
     Clinical Observation of the Composition of the Present Invention in Treating Viral Diarrhea 
     1. Clinical Data 
     1.1 General information. 108 children outpatients with diarrhea were randomly divided into treatment group (54 cases) and control group (54 cases). All cases had obvious dehydration before treatment, and the number of diarrhea in 24 hours was more than 5 times. There were 54 cases in the treatment group, including 31 boys and 23 girls, aged 1 to 5 years old, with an average of 2.7 years old. There were 54 cases in the control group, including 34 boys and 20 girls, aged from 1 to 4.8 years old, with an average of 2.4 years old. After statistical processing, the clinical data of the two groups are comparable (P&gt;0.05). 
     1.2 Treatment methods. The two groups were given symptomatic treatment such as rehydration. The treatment group orally took the composition prepared in Example 2 of the present invention with 50% taro, 25% carrot, 25% rice and glutinous rice in the ratio by weight. For infants with diarrhea from 6 months to 3 years old, 3.5 grams of the pharmaceutical composition were rinsed with warm water and taken orally, 6 times a day. For children with diarrhea over 3 years old, 7 grams the pharmaceutical composition were rinsed with warm water and taken orally, 3 times a day. Taking for 3 consecutive days is one course of treatment. The frequency and severity of diarrhea were observed, and routine blood tests, urine tests, liver function tests and kidney function tests were carried out before and after treatment.

     EXPERIMENTAL EXAMPLE 2 
     Clinical observation of the pharmaceutical composition of the present invention in treating diarrhea caused by lactose intolerance and milk protein allergy diarrhea in infants and children. 
     1. Clinical Data 
     1.1 General information. 100 outpatients with persistent diarrhea caused by lactose intolerance and milk protein allergy were randomly divided into treatment group (50 cases) and control group (50 cases). There were 80 children with lactose intolerance and persistent diarrhea, 60 children with milk protein allergy, and 40 children with milk protein allergy and lactose intolerance. All cases had symptoms of diarrhea after consuming breast milk or hydrolyzed formula powder containing lactose before treatment. Diarrhea occurred half an hour after breastfeeding and was detected as lactose intolerance and/or milk protein allergy. There were 50 cases in the treatment group, including 35 boys and 15 girls, aged from 6 months to 3 years old, with an average of 1.6 years old. There were 50 cases in the control group, including 26 boys and 24 girls, aged from 7 months to 2.5 years old, with an average age of 1.4 years old. After statistical processing, the clinical data of the two groups are comparable (P&gt;0.05). 
     1.2 Therapeutic method. The treatment group orally took the composition prepared in Example 2 of the present invention with 25% taro, 20% carrot, 30% rice and 25% glutinous rice in the ratio by weight. For infants with diarrhea from 6 months to 3 years old, 3.5 grams of the pharmaceutical composition were rinsed with warm water and taken orally, 6 times a day. For children with diarrhea over 3 years old, 7 grams the pharmaceutical composition were rinsed with warm water and taken orally, 3 times a day. Taking for 5 consecutive days is one course of treatment. The frequency of diarrhea was observed before and after treatment. The control group orally took lactase according to the method and dosage of the instructions. 
     1.3 The standardization of efficacy evaluation. Significantly effective: diarrhea frequency in 4 hours after feeding ≤1 time; Effective: 1 time&lt;diarrhea frequency in 4 hours after feeding ≤2 times; and Ineffective: diarrhea frequency in 4 hours after feeding ≥3 times, the diarrhea frequency is not significantly reduced or there is no obvious reduction in watery stools.
