What to do about lactose intolerance
When the lactose that is not decomposed and absorbed enters the colon, it is fermented by the bacteria present in the intestine into small molecules of organic acids such as acetic acid, propionic acid, butyric acid, etc., and produces some gases such as methane, H2, CO2, etc. Most of these products can be reabsorbed by the colon, while those that are not absorbed or lactose that is still not decomposed can cause symptoms such as bowel sounds, bloating, abdominal pain, exhaust, discomfort, diarrhea, etc. Some people also experience belching, nausea, etc. These symptoms are called lactose intolerance. Lactose intolerance symptoms vary greatly among individuals. Severe lactose intolerance mostly occurs within 30 minutes to a few hours after ingesting a certain amount of lactose.
Lactose intolerance affects infants and children and can be accompanied by diaper rash, vomiting, growth retardation, and sometimes nausea in adults. The number and severity of intolerance symptoms are related to a number of factors, such as lactase activity in the small intestine, the amount of lactose consumed, and whether other foods are consumed at the same time.
The long-term effects of lactose intolerance in children are likely to include calcium malabsorption, diarrhea, chondropathy, low body weight and growth retardation, especially in children with congenital and secondary lactase deficiency, which can lead to refractory diarrhea and chronic diarrhea in infants and children.
Addressing lactase deficiency. Several recommendations are given below.
1. Drinking too much milk at once or drinking milk on an empty stomach may induce lactose intolerance. Take a scientific approach to milk drinking, such as not drinking milk on an empty stomach and eating some food beforehand; do not drink a large amount of milk at one time, and do not drink more than 100 ml each time; one serving of milk can be divided into several servings; increase the amount of milk drunk a little bit every day to gradually adapt.
2. Eat with cereals. Generally speaking, lactose intolerant people will have heavy symptoms when drinking milk on an empty stomach, but when mixing meals, the lactose concentration of milk may be “diluted” in a specific environment. Increased celiac action and mechanical movement in the gastrointestinal tract can improve the absorption of lactose. Eating cookies or bread before drinking milk will reduce gas and discomfort.
Drinking milk powder with some cereal will also make a good way to eat together. In particular, some milk powder is generally processed by high temperature and pressure, and the addition of sucrose and other additives such as lactase or lactobacillus, lactose is partially decomposed and diluted, the human body will be easier to absorb and use. And the content of lactose in brewed milk powder is also easy to control, more suitable for such specific people.
3, a small number of times. Each lactose intolerant person shows a different reaction, some people drink a cup (containing about 12g lactose) on belly bloating, diarrhea; some people drink half a cup and have a reaction. In other words, to a certain extent, milk can be tolerated. Therefore, if a glass of milk divided into two drinks, or take a small number of times the method can be dissolved or not occur at all any symptoms.
4, drink yogurt. Yogurt is generated by adding certain lactic acid bacteria after fermentation. The fermentation process makes 20-30% of the lactose in the original milk break down into yogurt, and the protein and fat also break down into smaller components, making it easier to digest and absorb.
5, add a piece of lactase or milk powder containing lactase. Lactose intolerance occurs because the body lacks lactase. If you drink milk with a piece of lactase, it will be easy to prevent uncomfortable symptoms because external aid lactase can also improve lactose digestion and absorption.
The tip of the human small intestine villi contains a large amount of lactase, and lactose will lactase break down into galactose and glucose to be absorbed by the small intestine. As a result of acute enteritis in babies, the microvilli of the small intestine are damaged, so the lactase enzyme is most susceptible and lacking in large quantities.
Five major causes of lactose intolerance
Lactose is a sugar contained in milk and must be hydrolyzed in the small intestine by lactase into two monosaccharides, glucose and lactose, before it can be absorbed. In people with lactase deficiency, after eating milk or milk products, the lactose in the milk cannot be completely digested and absorbed and stays in the intestinal lumen, which increases the osmotic pressure of the intestinal contents, increases the volume and speeds up the intestinal emptying, so that the lactose is quickly discharged to the large intestine and absorbs water in the large intestine, and is fermented and gassed by the action of bacteria. Doctors call this lactose intolerance. Specifically, there are five major causes as follows.
1, congenital lactase deficiency: refers to the body since birth lactase activity is low or lack of, is the body on the autosomal recessive gene, this type is rare
2, primary lactase deficiency: also known as adult lactase deficiency, is due to human generations of dietary habits leading to genetic changes, the incidence is related to age and race, most people belong to this type
3, secondary lactase deficiency: refers to the temporary low lactase activity due to various causes of small intestinal epithelial damage, common causes such as infectious diarrhea, recovery from organic disease can be restored to normal
4, for children, autumn diarrhea, bacterial diarrhea will cause temporary low gastrointestinal function, lactase secretion is reduced or activity is reduced, continuous milk consumption will cause secondary lactose intolerance
5.After high doses of service cephalosporins and endocannabinoid antimicrobials can also cause secondary lactose intolerance.
Life care.
The nutritional effects of dairy products on the human body are well known to all. How to solve the majority of lactase deficient people, the discomfort and distress in the consumption of milk and its dairy products, has been a problem that the nutrition and dairy industry is committed to solve. Here are a few suggestions to try.
1. Eat with cereals. Generally speaking, lactose intolerant people who drink milk on an empty stomach will have more severe symptoms, but the lactose concentration of milk may be “diluted” in a specific environment when mixing meals.
Increased celiac action and mechanical movement in the gastrointestinal tract can improve lactose absorption. If cookies are eaten before or with milk, bread will reduce gas and discomfort. If you drink milk powder, adding some cereal to eat with it is also a good way. In particular, some milk powder is generally processed by high temperature and pressure, and the addition of sucrose and other additives such as lactase or lactic acid bacteria, lactose is partially decomposed and diluted, the body is also easier to absorb and use. And the content of lactose in brewed milk powder is also easy to control, more suitable for such specific people.
2, a small number of times. Each lactose intolerant person shows a different reaction, some people drink a cup (containing about 12 grams of lactose) of milk on belly up, diarrhea; some people drink half a cup and have
reactions. In other words, to a certain extent, milk can be tolerated. Therefore, if a glass of milk into two drinks, or take a small number of times the method can be dissolved or not occur at all any symptoms.
3. Drink yogurt. Yogurt is generated by fermentation with the addition of certain lactic acid bacteria. The fermentation process makes 20-30% of the lactose in the original milk break down into lactic acid, and the protein and fat also break down into small
The fermentation process causes 20-30% of the lactose in the original milk to be broken down into lactic acid, protein and fat to be broken down into smaller components, and calcium, iron, zinc and other minerals that are beneficial to the body to be dissociated from the larger molecules, making it easier to digest and absorb.
4, add a piece of lactase or milk powder containing lactase. Lactose intolerance occurs because the muscle lacks lactase, so if you drink milk with a piece of lactase it will be easy to prevent uncomfortable symptoms, because external aid lactase can also improve lactose digestion and absorption. Tests have proven that women with lactose intolerance who drink a glass of milk with one tablet of lactase can reduce the symptoms of intolerance and completely change the previous feeling. There are now milk powders on the market that contain lactase, so try them.
