from the gutsy-research dept.

"It was known that green tea polyphenols are more effective and offer more health benefits than black tea polyphenols since green tea chemicals are absorbed into the blood and tissue," said Susanne Henning, the study's lead author and an adjunct professor at the UCLA Center for Human Nutrition. "Our new findings suggest that black tea, through a specific mechanism through the gut microbiome, may also contribute to good health and weight loss in humans."

That specific mechanism seems to be that it changes the ratio of bacteria in the intestine by increasing the microbes associated with lean body mass and decreasing those associated with obesity. While both green and black teas act as prebiotics in this way, it seems that black tea might have a leg up over its green partner.

The study fed four groups of mice different diets. One group ate low-fat, high-sugar foods,while another had high-fat, high-sugar meals. The other two were both on a high-fat, high-sugar diet but one got green tea extract, while the other received black tea extract.

[...] Because black tea seems to work in the gut, while green tea works in the liver as well as the gut, a combination of both drinks might be most helpful, especially since both beverages have been linked to multiple health benefits beyond weight loss.

The researchers did not specify how much sugar to mix with your black tea.

    Hi, Could you please reference papers supporting the link between Hashimoto's and IBS?

    I would if I could find 'em offhand. Over the years I've collected a huge mass of literature, and it's become scattered across multiple systems, and I haven't kept track of sources (tho it largely comes from articles published in JCEM and BMJ. My background is biochemistry, which is helpful in weeding out BS.)

    However I can tell you how I most likely got there -- start here:
    http://hormonerestoration.com/files/TSHWrongtree.pdf [hormonerestoration.com]
    If you track down the citations, and their citations... one of them eventually brings you to a list of academic papers -- 128 pages long. It's probably in there!

    The articles on bipolar vs thyroid are particularly interesting. One shrink achieved a 90% cure on his bipolar patients by taking them off all other meds and treating them solely with T3. (And I looked at that vs the Hashi mechanism, and thought -- well, d'oh...)

    Also, it looks like hyperparathyroidism is actually the end-stage, not a separate disease. (The only study I've seen that's looked at this found 100% of their HPT patients had Hashi antibodies, even tho they'd tried to screen out thyroid disorders. Which makes sense considering how HT affects calcium transport.)

      Thanks, but that's actually not very helpful when you make strong assertions like

      IBS is so strongly correlated with Hashimoto's thyroiditis (something like 99% when patients are actually checked for thyroid antibodies) that some endocrinologists now consider IBS a positive diagnostic all by itself.

        You can believe it or not as you like. Most doctors won't believe it either, but they don't read the literature, and thyroid is barely touched on in their schooling, because the old idea that it's a fixed syndrome with limited symptoms is still prevalent, as is the idea that TSH tells all (I found the original study on how TSH range was determined, it was appalling bad science). Some are willing to read and learn, others are not. JCEM back issues are online for all the world to see.

        One problem is that because symptoms are so variable, for each and every study finding X, there is an equal and opposite study finding not-X -- in one case using the same data!! But this typically changes if they bother to check Hashimoto's antibodies (which by definition indicate a history of thyroid disease), or look at tissue T3 (which often does not reflect TSH or even T4, especially in the elderly). The HPT study had tried to actively exclude thyroid disease and was looking for something else entirely, so was shocked to discover that for their remaining sample, 17 for 17 had Hashimoto's antibodies (they weren't even planning to check that, but one of the researchers had an intuition, and there ya go.)

        But having read hundreds of studies, and having the background to grok the concepts -- I've concluded that for ANY chronic condition (including psych disorders), and for ALL cases of age-related disease or debility, thyroid should be the FIRST thing investigated and in full depth, not the last resort and just a TSH test as is typical (if they look at it at all). It affects absolutely everything -- it can even have such vague and apparently-unrelated symptoms as adult-onset tooth decay (because it indirectly causes calcium robbing) and elephantiasis (thyroid antibodies can also attack the skin and joints). Normalize thyroid, and a host of apparently-intractable disorders go away without further treatment.
