Probiotics in yogurt can only live 7 days, drinking yogurt with a shelf life of 6 months is still meaningful?

original title: Probiotics in yogurt can only live 7 days, drinking yogurt with a shelf life of 6 months is still meaningful?to improve taste, adding sugar and thickeners to yogurt also brings extra energy and the effects of intestinal urination.One, the main role of probiotics is to make the milk sour When we drink milk, if we taste the sour taste in the milk, everyone's first reaction must be "this milk is broken", and then quickly spit out. This sour taste in milk is the taste produced when the lactose in milk is broken down by bacteria to form lactic acid.the air of bacteria have good or bad, normal placement of acid-changing milk contains a large number of harmful bacteria to human body, can no longer eat. So smart
people take the initiative to add harmless bacteria to the milk, so that milk can become "acid", but also harmless to the human body
, it made a unique flavor of yogurt food., milk acidity after nutrition is easy to absorb milk contains a large number of high-quality protein, as well as calcium, iron, phosphorus and other trace elements, the nutritional value of the human body is very high. Milk contains lactose, making the natural milk itself with a faint sweet taste. But in humans, some people lack enzymes that digest lactose, which can cause lactose intolerance. After drinking milk, these people develop symptoms of bloating, diarrhea, abdominal pain and other digestive tracts.milk is "processed" by beneficial bacteria, so that lactose into lactic acid, milk into yogurt, it is a perfect solution to the problem of lactose intolerance
. So that people who could not drink milk, by drinking yogurt, can also easily enjoy the nutrition in milk., overrated beneficial bacteria When you drink yogurt, you often hear an ad saying is "supplement beneficial bacteria, improve micro-ecological." But this sentence is only advertising effect, yogurt beneficial bacteria brought about by the micro-ecological improvement effect is "minimal." Because
to have beneficial bacteria to have a role in improving micro-ecological, there are two prerequisites: first, to live beneficial
bacteria;but meeting these two conditions is not easy, the beneficial bacteria in yogurt can only survive about 7 days, but also need to be refrigerated. Therefore, only refrigerated preservation, shelf life of less than 7 days of yogurt, only contains active beneficial bacteria. And those marked "normal temperature storage" of yogurt, are through the sterilization process, which does not contain active bacteria.even active yogurt, it's too hard to reach the gut. Because our stomach acid is strong acid, it can kill almost all bacteria. To keep the beneficial bacteria in yogurt alive to reach the gut, make sure you eat enough and serve with other foods. The barrier formed by other foods ensures that beneficial bacteria enter the intestines to function.containing active bacteria from the production, storage, transportation, sale, until the last drinking, all need to be kept in cold conditions, in order to survive beneficial bacteria. So many links, there is a problem, can not guarantee the activity of beneficial bacteria. But even if the beneficial bacteria die out, will not affect the taste and nutritional composition of yogurt, so how many beneficial bacteria in yogurt to reach the intestines, can ultimately produce a beneficial effect, is a very "mystery" thing., yogurt can not help digestion often mentioned yogurt another role is "help digestion", but yogurt actually can not help digestion. The digestive and absorption process of the human body is mainly related to the peristaltic of the digestive fluid, digestive enzymes and the digestive tract itself. Yoghurt and the probiotics inside do not increase the content of digestive fluids and digestive enzymes, and do not help digestion.but in order to increase the taste of yogurt, yogurt will be added to agar, pectin, gelatin and other thickeners. This is a large molecular substance, can not be absorbed by the human body, through the digestive tract will absorb water expansion, and finally with the feces discharge. This thickener is actually similar to dietary fiber and promotes intestinal peristalsis and deflecing. So yogurt can not help digestion, but can moisturize the intestines, constipation people can drink more appropriately.
