Probiotics have always given people the impression of being "good for the intestines and protecting the brain." However, recent foreign studies have found that long-term use of probiotics may cause "D-lactic acidosis", causing confusion in the brain and poor concentration. Symptoms such as concentration and bloating. What exactly is "D-lactic acidosis"? Should people continue taking probiotics? See what the nutritionist says!

Regular consumption of probiotics may lead to D-lactic acidosis! ? US research sparks heated debate

The World Health Organization (WHO) has stated that probiotics are live microorganisms that, when taken in sufficient amounts, can produce one or more proven effects on the human body. Functional health benefits. In Taiwan, there are currently many probiotic products that have been reviewed by the Food and Drug Administration of the Ministry of Health and Welfare and certified with the Health Food Label. Most of them claim that there are hundreds of species of bacteria in the human digestive tract, and that moderate supplementation of probiotic products can increase intestinal intestinal function. Probiotics help the intestines maintain a stable and normal bacterial ecology, thereby avoiding constipation, diarrhea and other digestive tract discomforts.

However, a recent study from Augusta University in Georgia, USA, found that long-term use of probiotics may cause D-lactic acidosis, temporarily making the brain unable to think clearly. , and can't concentrate. As soon as this study was published, it caused panic among people who have been accustomed to taking probiotics for a long time, and the issue of "whether probiotic supplementation is necessary" has once again been discussed.

"D-lactic acidosis" may have more than one cause

To find out the answers to these questions, let's first understand what "D-lactic acidosis is"! In clinical practice, D-lactic acidosis is an uncommon but easily overlooked metabolic acidosis. You Weiming, a nutritionist at St. Martin's Hospital, said that generally speaking, healthy intestinal metabolism is not prone to increased D-lactic acid concentration. , most occur when resection of the small intestine results in malabsorption. After small intestine resection, the carbohydrate metabolism process causes malabsorption of easily fermentable sugars. A large amount of sugars enter the large intestine and ferment into D-lactic acid, which can easily lead to D-lactic acidosis.

It is worth noting that the cause of D-lactic acidosis may be other reasons besides taking probiotics for too long. Everyone’s situation is different. It is recommended to consult a doctor or nutritionist first. Correct attribution. According to a 2010 study published in the Journal of Internal Medicine by nephrologists Zhang Youming and Yang Chuixun, the content mentioned that the following 6 situations may also lead to an increase in D-lactic acid concentration in the body:
