What are the dangers versus advantages of consuming kombucha?
Is Kombucha Tea Good for You? is considered one of my first movies. It was featured in a weblog entry entitled “NutritionFacts.org: the primary month,” the place I marveled the video had reached practically 100,000 folks. You may see it under and at 0:20 in my video Kombucha’s Facet Results: Is It Unhealthy for You?. I’m honored to say that we now attain greater than 100,000 folks a day.
In that first kombucha video, I profiled a report printed within the Journal of Intensive Care Medication of “a case of kombucha tea toxicity” through which a younger man ended up in an acidotic coma. The authors concluded, “Whereas Kombucha tea is taken into account a wholesome elixir, the restricted proof at present obtainable raises appreciable concern that it could pose critical well being dangers. Consumption of this tea ought to be discouraged, as it could be related to life-threatening lactic acidosis.” And this was simply considered one of a number of case studies of “critical, and generally deadly, hepatic [liver] dysfunction and lactic acidosis inside shut proximity of ingestion.”
For instance, there have been two circumstances in Iowa of extreme metabolic acidosis, together with one demise. There was additionally a triggering of a life-threatening autoimmune muscle illness that required emergency surgical procedure and was “in all probability associated to the consumption of a fermented Kombucha beverage.” One other affected person offered with shortness of breath, shaking, and a motion dysfunction “after consumption of tea and no different drugs,” and a middle-aged lady complained of xerostomia, dizziness, nausea, vomiting, headache, and neck ache,” and her signs recurred on reingestion of the tea. There was one other case of extreme metabolic lactic acidosis, in addition to a case of hepatotoxicity (liver toxicity) that resolved after stopping kombucha.
Why these sporadic circumstances? Perhaps some uncommon toxins developed in a specific batch. I imply, it is a fermented product, so it’s doable there was just a few contamination by a foul bug, just like the time folks smeared kombucha on their pores and skin as a result of they have been advised it had “magical therapeutic energy.” What it had as a substitute was anthrax. So, though such studies have been uncommon, I concluded ten years in the past that we should always in all probability keep on with meals that haven’t put folks in a coma. However what about its dangers versus advantages? Perhaps kombucha is value it. In spite of everything, it’s “reputed to treatment most cancers,” “eradicate wrinkles,” “and even restore grey hair to its unique colour”—as “marketed by different and naturopathic healers all through the US.”
“At present, kombucha is alternately praised as ‘the last word well being drink’ or damned as ‘unsafe medicinal tea.’” It’s been “claimed to be a common fantastic drug…a potion which improves consciousness and focus, slimming, additionally purifying, regenerating and life extending.” Which is it? Is it “potion or poison?
Again within the Nineteen Twenties, Thirties, and Forties, there have been a number of medical research carried out by acknowledged physicians confirming all types of useful results, as you’ll be able to see under and at 2:55 in my video.
I couldn’t wait to learn them. Dufrense and Farnworth have been cited, and after I went to that paper, I noticed the identical declare, citing Allen 1998. Once I went to that supply, I noticed the quotation is for a random kombucha web site, as proven under, and at 3:10 in my video. And guess what? That web site’s been defunct since 2001, and “a lot of the Kombucha info” posted got here from feedback on some mailing listing.
Lastly, in 2003, a scientific evaluate of the scientific proof that had been printed was carried out. “The principle results of this systematic evaluate, it appears, is the full lack of efficacy knowledge…No scientific research have been discovered regarding the efficacy of this treatment.” We simply have these cautionary tales, these case studies. So, primarily based on these knowledge, it was concluded that the largely undetermined advantages don’t outweigh the documented dangers of kombucha. It may well subsequently not be really helpful for therapeutic use.” That was again in 2003, although. How a few 2019 systematic evaluate of the empirical proof of human well being benefit?
“The nonhuman topics literature claims quite a few well being benefits of kombucha,” with “nonhuman” that means mice and rats. We want human scientific trials, but there may be nonetheless not a single managed human examine. (I did discover one uncontrolled examine purporting to point out a significant discount in fasting and after-meal blood sugars amongst people with sort 2 diabetes, although, as seen under and at 4:19 in my video.)
“Nonetheless,” regardless of no managed trials, “significant industrial shelf area is now devoted to kombucha merchandise, and there may be widespread perception that the merchandise promote well being.” So, we are left with this excessive disparity between science and perception: “There isn’t any convincingly constructive scientific proof in any respect; the [health] claims for it are as far-reaching as they’re implausible; the potential for hurt appears appreciable. In such excessive circumstances, healthcare professionals ought to discourage customers from utilizing (and paying for) cures that solely appear to learn those that promote them.”
