Can t remember the name of someone, forget to bring a money bag... Is the "brain fog" caused by probiotics?

A few days ago, a friend saw a news article saying "Take probiotics to cause brain fog" (please call me for details), and I came here to ask Fuen's opinions very tightly.
Ven's suggestion is very similar to this article: you can eat it as usual, but don't eat it to the point of being savory (but generally the number of probiotics will not be too high, and the general way to eat it will not reach the point of being savory).
The reason is that the methodological problems of this study are still very difficult to establish a causal relationship over the past few days. Then excessive hyperplasia of brain or nephrotic bacteria is complex phenomena that lack clear definitions and do not have a targeted evaluation standard. The causes and symptoms may vary, so this evaluation is not scientific. So I think this matter is too early.
Burinal fog is a popular topic recently in international health issues, describing a situation where people suddenly can’t remember things, forget to bring money, can’t call out a person’s name, suddenly lose their attention, etc. In fact, the scope is quite conclusive, and the causes are also related to pressure, lack of sleep, excessive use of 3C, lack of vitamin D, micro-inflammatory in the body, or bacterial infection.
There should be many people in Taiwan who have brain fogs. For example, when you meet someone who can't name them, you can't write them in Chinese characters, and you can't write them out. If you want to study the phone number at your home, it suddenly becomes blank. In short, it has a lot to do with the busy modern lifestyle. Instead of worrying about whether probiotics will cause this, it is better to adjust yourself first and start by relaxing your mood, maintaining a normal schedule, and eating normally. (The above is a common talk about by old people).
In short, don't worry too much about probiotics. Probiotics still have more benefits to human health than disadvantages.
