- New study shows that a Yakult probiotic drink helps people with lactose intolerance and the benefits persist 3 months after one month of drinking it. Yakult is common in Chinese and Japanese supermarkets but rare in American ones. Until I read this article, I didn’t realize that people drink it because of lactose intolerance, which is much more common in Asia than America. Via Cooling Inflammation.
- news from the Human Microbiome Project. “To the scientists’ surprise, they also found genetic signatures of disease-causing bacteria lurking in everyone’s microbiome. But instead of making people ill, or even infectious, these disease-causing microbes simply live peacefully among their neighbors.” You may recall that a Nobel Prize was given for the discovery that ulcers are caused by a certain species of bacteria. However, almost everyone with the “disease-causing” bacteria does not get ulcers. Apparently the “surprise[d]” scientists studying the human microbiome did not know that. If it were better known that you don’t need to kill bacteria to make them harmless, antibiotic usage would be less attractive.
