Hydroxycut became popular first as a version of the bodybuilder's infamous trio: caffeine, ephedra, and Asprin: in this case guarana extract, ephedra extract, and white willow bark for the natural ASA. After ephedra was banned they switched to a blend of other popular ingredients: Garcinia cambogia, Gymnema sylvestre, chromium polynicotinate, caffeine, green tea- and Citrus Aurantium, which is inexplicably not mentioned in the Knowledge (XXG) article on Hydroxycut. The studies cited only attribute a causal association between liver failure and Hydroxycut as a whole: there is no reason to single out Camellia sinensis as the culprit- and given that tea is exponentially the most widely-used ingredient that happens to appear in that formula (excepting caffeine), the likelihood of the tea (a minor ingredient in the capsules)being the problem is almost nil. The Citrus Aurantium (Bitter Orange) peel, used as a source of synephrine to replace ephedrine, is the most likely culprit, coupled with excessive caffeine. Add in the new Hydroxycut Advanced, and you're talking about at least three different formulations of the product- and given the timeline, it's entirely possible that the liver failure cases were in customers who had NO tea in their capsules. Specifications per dose of Hydroxycut (2000mg):
555:. 'Preventing HIV' is relative, and anything that reduces the likelihood of binding to T-cells will in theory both reduce the spread rate and increase the watershed virus count before full infection. Certainly it is possible for the immune system to completely defeat a very small number of HIV in your system. If, hypothetically, two identical people were going to be infected with two identical very small amounts of identical HIV virus which was marginally above the level that would infect that person, the paper conjectures that if one took megadoses of EGCG prior to infection, it's possible (according to the study) that he might not contract HIV while his counterpart would. Dicey claims, yes, but it's cited, and debates over plausibility are original research.-₪- 1705:, I think you are reading it too literally, and it is impacting your ability to allow this article to be improved. Indeed, that is the intention of the editors here, and I do assume good faith. As such, I will continue to try to improve this article here. One issue that stands out: a statement by the FDA, which you claim is the only thing right now that is satisfactory about tea and cancer (which, as others have pointed out, considering the relaible resources available on this topic, is nonsense) from 2005 that mentions only two studies (primary studies) and includes a general note on research they have skimmed. Dated and general. But apparently that satisfies your criteria. Doesn't add much to the article or heading, though. 1561:. Basically, for health-related content we only report the findings and conclusions of expert reviews. That way we are most likely to be presenting the current expert opinion. When Knowledge (XXG) articles are based on a collection of primary sources (epidemiological studies, randomised control trials, in vitro studies, animal models, etc.) they are acting like a review, but a review written by anonymous authors, with no expert oversight, and quite likely no rigor. The down side of the guideline is we have to wait, sometimes quite a long time, before someone publishes an authoritative review. But it's the most responsible method anyone's come up with, so far, of ensuring we don't mislead. -- 2067:"Weight loss" is an ill-defined term for a very complex subject encompassing not only absolute loss of weight, but also fat oxidation, fat composition (white vs brown adipose tissue), total energy expenditure, modulation of energy expenditure or fat oxidation during exercise, etc. To state that tea has no meaningful effect on weight loss is to state tea has no impact on any of these on the scales humans would find relevant. Yet numerous other studies implicate tea (and tea extract) in exactly these, which along with being aligned with the effects acknowledged in Johnson, Bryant, Huntley (2012), brings it at odds with the current presentation. 2757:
than the tea most likely). GTE is not solely in weight loss supplements and no matter where they are, they pose a risk to a small portion of the population. If people want more papers cited, I am happy to do a lit review. I am unfortunately very familiar with this as eight years ago, I almost died from exposure to green tea extract. I do not recommend liver failure, it's no fun. Most importantly, if you have had the reaction once, it should be treated like an anaphylaxis allergy, because it is known that with every exposure, the reaction will be worse.
2551:
can contradict, yet the Cochrane review is narrower in scope (dealing mainly with studies with obese individuals) and cannot on its own serve to contradict the use of tea in weight loss in general. For this reason, it sounds weaselish and superfluous. Plainly stating that a review did not find a significant benefit for weight loss in obese individuals would be much more neutral and accurate. After all, the rest of the article is filled with plain claims such as "A review found " and it is quite common on Knowledge (XXG), so why is it a problem here?

text is written on this page is inherently misleading; the text currently reads: "The possible beneficial health effects of tea consumption have been suggested and supported by some studies, but others have found no beneficial effects". This is misleading--it is true that some studies have not found/confirmed any beneficial effects of tea...however, many other studies have. And, I haven't read a single study where the authors have strongly questioned whether tea has any beneficial properties. For example, this abstract:

than non-tea drinkers. Coffee consumption did not show any effect except at the very highest level of consumption, where it was associated with significantly decreased decline of 20 percent. The study used data on more than 4,800 men and women aged 65 and older from the Cardiovascular Health Study to examine change in cognitive function over time. Study participants were followed for up to 14 years for naturally-occurring cognitive decline. (AAICAD 2010; Lenore Arab, PhD; UCLA

Calling it "Potential" seems to introduce POV (and I would say is outright wrong--because Tea obviously has

previously and one that is easily available offers new hope. Weight loss products made from natural sources, such as green tea, are being used by increasing numbers of overweight adults who hope that because the product is 'natural' it will be safer than prescription drugs and will be effective in helping them lose weight. " If anything we should be expanding on this consumber/SCAM aspect of green tea as a weight-loss aid.

And I say NPOV because this "However there is some positive evidence for risk reduction of breast, prostate, ovarian and endometrial cancers with green tea." seems to be missing from footnote 13, though apparently what you included is okay. Hmm.

Again, with GTE being added to so many products, it is important for people to be aware.

I'm sure you know that no cure for HIV exists. Once you have it, you'll die with it. But 'having HIV' is defined by having a certain count of the virus in your system (or more precisely, by T cell count, which is a proxy for virus count). 'Prevent' HIV infection is what the source claims, which by

In 2010 researchers found that people who consumed tea had significantly less cognitive decline than non-tea drinkers. Study participants who drank tea 5-10 times/year, 1-3 times/month, 1-4 times/week, and 5+ times/week had average annual rates of decline 17%, 32%, 37%, and 26% lower, respectively,

It is my understanding from reading a pretty broad variety of articles on this topic that there's a scientific consensus that tea is generally beneficial. The debate in the scientific literature seems to center around which ways in which tea is beneficial--not whether it is beneficial. The way the

I'm not qualified to do anything but reference. But isn't it good to write a paragraph after the FDA one simply noting that research in 2006 - 2012 finds this and that. There are many more than those three I provided, and for other cancers, but those are the three that seemed strongest and that I

How about leaving the old FDA statement, but then qualifying it with the new research? Something like While the FDA in 2005 finds XYZ, these later rigorous (prospective double blind etc) studies found LMN. Did you read the research?, which looks like gold standard stuff. There's also a new study

The Cochrane summary is mainly talking about findings of previous studies which showed metabolic activity of various compounds in tea and serves as a motivation for the meta-analysis. The beginning of your sentence sounds primarily like it is setting the stage that the latter part of your sentence

It seems we have an issue of NPOV here. I've tried to find some balance here but you appear, as it has been mentioned by others here, to want to list only the drawbacks and mention nothing about potential benefits re: cancer. There is no reason why my citations did not satisfy MEDRS. The citations

In short, the Hydroxycut observations are misleading, have nothing to do with tea, and should be removed from the article. In fact, I'm doing it now, and until someone provides a shred of reputable evidence linking TEA (as a singular ingredient) with any cases of liver failure, it should stay out.
1110:
The connection of Hydroxycut's reported side effects to the tea extract compound is irresponsible, and makes a claim that has no foundation or evidence: "liver damage, caused in part or completely by the presence of green tea extract in these supplements; the most notable cases include Hydroxycut"

The Cochrane review says "Preparations of green tea are used as aids in weight loss and weight maintenance. Catechins and caffeine, both contained in green tea, are each believed to have a role in increasing energy metabolism, which may lead to weight loss". In other words, green tea is popularly

Again, you are overstating what is claimed in the review. On a closer reading of the full review, several claims make this obvious. For instance, on page 23, the review discusses a subset of studies which attempted to intervene without caffeine and which found a statistically significant effect,

Overbrewing tea makes it healthier. The bitterness is actually caused by increases in antioxidant capacity and total phenolic and catechin contents as well as caffeine. The so called tannins which some claim occur in overbrewed tea is in fact simply the concentrated tastes of these flavonoids.

Since Fluorine is an element, it seems unlikely that the processing differences for green, white, or black teas could result in changed fluoride levels. It will depend on the fluoride content of the original plant, which is largely determined by the soil in which it was grown.

I just did a search of the scholarly literature and was unable to find a single article backing up this claim that Green tea lowers testosterone. The only hits I find in google are on internet forums and even then, they seem to be discussing this as a myth or misconception.
2578:"Best" in what way? If there are multiple conflicting reviews and one does not obviously supersede the other (for instance, by taking into account new evidence), how is it decided which one is "best"? It seems obvious an unbiased report should take both sources into account. 390:
