Yogurt manufacturers say that "probiotics are collected from the intestines of centenarians". What are the problems behind novelty?

The problem behind novelty is safety and hygiene. The idea of collecting probiotics from the intestines of centenarians to make yogurt is really surprising. Although the idea is novel enough, there are many problems behind it. From the manufacturer's point of view, the reason why they have the idea of collecting probiotics from the intestines of centenarians is because they think that the longevity of these elderly people shows that their intestinal flora is very healthy. If the intestinal flora in these elderly people can be applied to yogurt, won't it bring benefits to more consumers?

Although the idea is really good, there are many problems in the process of concrete practice. From the consumer's point of view, the greatest concern is safety and hygiene. From a safety point of view, although these centenarians are healthy, will it conflict with consumers' own intestinal flora if they transfer their intestinal flora into yogurt for consumers to eat? After all, everyone's physique is different, and the flora such as the intestine is naturally different.

The intestinal flora of these centenarians is passed on to consumers through yogurt. If it causes intestinal discomfort, isn't it a burden to consumers' health? Secondly, from the health point of view, there are also many hidden dangers. Although these centenarians are healthy, it is difficult for them to avoid other diseases. If the intestinal flora carries some diseases, then the hygiene of these yoghurts is not up to standard.

Therefore, from the perspective of safety and hygiene, there are many hidden dangers in this idea of manufacturers. If yogurt manufacturers can really solve these doubts in consumers' minds, then the yogurt can be liked by everyone, otherwise it will only be abandoned by everyone.
