Some apparently rather useless Lactobacillus acidophilus
I always cringe when I see an acupuncture headline with ‘needle’ or ‘point’ in the title. Can’t the writer avoid the clichéd pun? I had an editor who commented that the titles of my essays are often obtuse. Probably true. In going back over my essays on SBM I often can’t tell from the title what I have written about until I read the article. It is a fine line between (what I think) is a clever title and obscurity. So gut check it is.
Time flies when you are having fun. I wrote about probiotics back in 2009.
My conclusion at the time:
Probiotics are useful for the prevention of antibiotic-associated diarrhea. Probiotics may be helpful in preventing other overgrowth syndromes or diseases associated, and perhaps with perturbations of the gut microbial flora such as IBS and colic.
Probiotics are foreign bacteria that are not a normal part of your GI tract; they do not enhance your immune system and, in normal people do not promote the nebulous bowel health.
If you are a normal human, with a normal diet, save your money. Probiotics have nothing to offer but an increased cost.
Medicine is not static and there have been interesting advances in the understanding of the human microbiome in health and disease since 2009, so for SBM and my own medical understanding, I thought it would be a good opportunity to review the topic. Although with over 12,000 references on the PubMeds, I will only touch on a smattering of the papers. My ID attending in medical school always referred to reading the medical literature as drinking from a fire hose. Indeed. (more…)
A correspondent asked me to look into the GAPS diet. I did. I was sorry: it was a painful experience. What a mishmash of half-truths, pseudoscience, imagination, and untested claims!
GAPS stands for Gut and Psychology Syndrome. It is the invention of Dr. Natasha Campbell-McBride. According to her, a wide variety of health problems can be traced to a single cause: an imbalance of gut microbes. She cites ancient wisdom: Hippocrates said all diseases begin in the gut. She says science confirmed that wisdom when it discovered that 90% of all cells and all genetic material in the human body belongs to the gut flora. She says the modern world poses many dangers for the gut flora, and once it is damaged, the health of the whole body enters a downward slide towards disease. She claims that autism and ADD, OCD, schizophrenia, epilepsy, depression, and numerous other ailments are all digestive disorders. (more…)
Remember this picture when I start talking about your spouse.
The Wall Street Journal has an assessment of probiotics in the Jan 13, 2009 issue entitled “Bug Crazy: Assessing the Benefits of Probiotics.” For some reason when I wander around the hospital on rounds people show me articles such as this and ask, so whatcha think about this? Probiotics are interesting. They are live bacteria given to treat and prevent diseases. It is one of those overlap areas for scientific medicine and so called alternative medicine. There are good clinical trials to suggest areas where these agents are of benefit, but other aspects of their use are blown out of proportion for the real or imagined benefit probiotics may provide. Much of alternative medicine where it overlaps with real medicine is the art of making therapeutic mountains out of clinical molehills. The Wall Street Journal article is the kind of reporting that drives. Me. Nuts. It drives me nuts because the reporting acts as if the underlying assumptions of the therapies are true. (more…)
