Yogurt may be the favorite fermented food at present, and it was commercialized earlier. Eating yogurt even became a fashion. Yogurt is delicious and attractive in color, which is welcomed by people of all ages. Some people even give themselves or their children a lot of sweet and delicious yogurt every day, thinking that yogurt contains probiotics, which can promote health. The more you eat, the better, but the result is often counterproductive.
A large number of studies have found that active probiotics in yogurt can promote human health, and long-term consumption can improve intestinal barrier and enhance immunity. However, it should be emphasized that fermented yogurt containing active probiotics has such effects, while inactivated probiotics or probiotics destroyed by various food additives have been difficult to exert their health care effects, and these substances that harm probiotics (various food additives) will also destroy beneficial microorganisms that originally existed in the stomach after being imported. And those lactic acid bacteria drinks that contain no live bacteria and are blended are more harmful.
Therefore, when purchasing yogurt, the healthiest and safest order should be: yogurt without live bacteria (such as sugar-free plain yogurt) > yogurt without live bacteria (such as domestic plain yogurt) > yogurt with live bacteria (all kinds of delicious yogurt). Be especially wary of yogurt with a particularly good taste, because naturally fermented yogurt will not have such a taste.
At the same time, low-temperature yogurt is better than normal-temperature yogurt. Generally, yoghurts that need to be refrigerated at low temperature all contain live bacteria, while normal-temperature yoghurts basically contain no live bacteria, because yoghurts with live bacteria will continue to grow and produce acid at normal temperature, resulting in poor taste and can only be stored at low temperature, while yoghurts without live bacteria will be very stable at normal temperature.
2. The most expensive fermented food-cheese
Cheese, also known as cheese, is mainly fermented by lactic acid bacteria and white mold or Penicillium. It is very popular in Europe and West Asia and enjoys a high reputation all over the world. Although cheese is high in calories, it is rich in active metabolites of probiotics and bacteria, which is beneficial to human body. Scientists believe that although the diet contains a lot of saturated fatty acids, the habit of eating fermented cheese every day is one of the main reasons why their incidence of cardiovascular and cerebrovascular diseases is lower than that of other countries.
Generally speaking, the better the fermentation, the more unique the taste and the higher the price, such as the French favorite blue cheese.
Unfortunately, this kind of fermented cheese containing probiotics is hard to buy in China, but there are many industrialized non-fermented cheeses (such as American cheese and cooked cheese), such as pizza cheese, bread cheese, and all kinds of delicious cheese sticks that are popular now.
