Yogurt is made of pure milk as raw materials, which is a fermented dairy product, which is rich in calcium and protein, and contains beneficial bacteria, which can promote gastrointestinal peristalsis and help food digestion.
What are the rumors about yogurt?
1, the more acidic yogurt nutritional value is higher
The reason why yogurt has a sour taste is because lactic acid bacteria promote lactose metabolism to produce a large amount of lactic acid, and the fermentation agent strain and fermentation time determine the lactic acid content, and its quality cannot be judged by the degree of sourness.
It is worth noting that the acidity of yogurt is limited, in the storage and transportation process is not well prepared for low temperature preservation, a long time placed outdoors or at room temperature, lactic acid bacteria will multiply in large quantities, thereby increasing its acidity, not only taste sour, but also reduce the vitality of lactic acid bacteria, but also cause milk protein degeneration, affect the body's absorption, disturb gastrointestinal health.
2, room temperature yogurt has no nutrition
Now there are two kinds of yogurt on the market, one is sterilized yogurt, that is, room temperature milk; the other is live yogurt, that is, low-temperature yogurt.
After the former is fermented by lactic acid bacteria, it is heat treated to kill the lactic acid bacteria in it, so it can be stored at room temperature. So the difference between the two is whether there are live lactic acid bacteria, and the nutrition of other ingredients is not bad.
3, yogurt calcium supplementation effect is not as good as milk
Many people think that milk has a higher calcium supplementation effect than yogurt, which is a wrong perception.
In the same amount, yogurt has a higher calcium content than milk. After yogurt is fermented, lactic acid decomposes the lactose in it into lactic acid, reduces the lactose content, and retains its nutrients to the greatest extent, so yogurt can also supplement calcium.
4, drink yogurt after a full meal can promote digestion
Some people accidentally eat too much will drink yogurt to promote digestion, it is undeniable that yogurt can speed up gastrointestinal peristalsis, stimulate the secretion of digestive juices, and proper drinking can indeed promote digestion.
However, after overeating can not drink yogurt immediately, the yogurt itself has a strong sense of fullness, and drinking yogurt after a full meal can increase the burden on the gastrointestinal tract, and also invisibly consume too many calories, and even cause obesity.
Therefore, whenever possible, schedule the time to drink yogurt between meals or 30 minutes before eating.
5, sugar friends can not drink yogurt
Although there are added sugars in yogurt, the glycemic index is not very high. Yogurt contains lactic acid, which can delay the emptying rate of the stomach and help control blood sugar after meals; yogurt is also rich in calcium, which can promote insulin release and help balance blood sugar. Therefore, under the premise of stable blood sugar, sugar friends can also drink yogurt appropriately.
6. The thickener in yogurt can cause blood to thicken
Yogurt thickeners include a variety of types, common are edible gelatin and pectin, can not be digested and absorbed by the body at all, this is insoluble dietary fiber, does not lead to blood viscosity, but can delay postprandial blood sugar and blood lipid rise, effectively prevent chronic diseases.
Tips
Yogurt contains a variety of vitamins and calcium as well as high-quality protein, which is suitable for almost every age group, especially for lactose intolerants.
However, when buying yogurt, you must take a closer look at the nutrition facts list, the first choice is high in protein content, you can not covet a cheap choice of yogurt that is about to expire, but also to buy big brand products.
It is worth reminding that although the nutritional value of yogurt is high, yogurt cannot be used to replace staple food, so as not to cause malnutrition.
