Guest guest Posted March 4, 2005 Report Share Posted March 4, 2005 You could be buying any old garbage. The supplement industry is poorly regulated. Why would you or anyone buy extracts of healthy foods instead of eating the foods themselves? We don't always know what components in the food or combo of components may be conferring the benefits - scientists are just learnng about these foods. So how would some two bit company who just wants to capitalize on the fears of consumers know? -- when scientists aren't even sure? I suggest you read Walford (which is a " must' here- especially if you want to post to the group) , read our files and links and learn more about eating a variety of health giving foods and save your money. on 3/4/2005 9:08 AM, Bob Malkin at strombolis@... wrote: > What are supplements that are sold as extracts?

Guest guest Posted March 4, 2005 Report Share Posted March 4, 2005 Vanilla is an extract, eg. A solvent poured through the stuff maybe ground up, like coffee, to get a fluid containing the stuff that can be gotten out by extracting. If you distill it like a brew, you concentrate the extract. Conceivably you could get the resveratrol out of grapes, wine, wine vinegar, or cognac (distilled wine). But what you have in that bottle only god knows. Another thought crossed my mind - that of the recent discussion of pomegranate juice, which has a lot of polyphenols. Now if I wanted to sell those, I might get a bunch of pomeg's crush them and extract the polyph's and sell those. That leaves a bunch of waste "juice" that I can sell as pomeg juice (which will probably taste better). I can't just dump it on the ground. I would leave off the label the fact I've removed the polyph's. (and don't forget to add the corn syrup, salt, coconut oil). Scary, huh?

Guest guest Posted March 4, 2005 Report Share Posted March 4, 2005 Hi Bob: Wine is ~85% water; ~12% alcohol; ~1% organic acids (variously tartaric, malic and lactic, plus traces of many others); glycerol; tannin; naturally occurring 'flavor/aroma components'; and all kinds of other compounds in microscopic quantities, including resveratrol which occurs in widely varying, but very small, amounts. I have also seen doubts expressed (of unknown reliability) about whether any resveratrol survives the digestive process.

Guest guest Posted March 4, 2005 Report Share Posted March 4, 2005 caveat emptor... all things being equal you are better off eating whole foods, there are many additional nutrients in healthy foods that aren't well understood, and there may also be subtle interactions with micro nutrient combinations. In the case of reservatrol , sounds like a good reason to drink some red wine (or eat grapes)...

I generally agree that whole foods are best, but, otoh, I've seen more than one study (either here or on the CR society list) wherein the salutary effects of blueberries (in rodents) were investigated and confirmed. But instead of using whole foods in such studies, it seems that blueberry extracts are usually, if not always, used. It sure would be nice to know where the investigators got their blueberry extract from. The allure of extract is that it's presumably much lower in calories than the corresponding whole food would be. Al Quote Link to comment Share on other sites More sharing options...
Guest guest Posted March 5, 2005 Report Share Posted March 5, 2005 December 10, 2004 Drinking tea not as beneficial as taking green tea supplements A study published in the December 2004 issue of the American Journal of Clinical Nutrition (http://www.ajcn.org/) found that green tea extract supplements offered greater bioavailability of polyphenols and increase plasma antioxidant activity compared to tea consumed as a beverage. Tea has been found to be protective against cancer and other diseases, and green tea polyphenols are taken in supplement form by many individuals to obtain their antioxidant and benefits. Researchers at the University of California, Los Angeles assigned three different sequences Darjeeling black tea, green tea or green tea capsules containing similar amounts of EGCG to 14 men and 16 women, with one week between each treatment period. Tea flavanol, theaflavin and caffeine were measured in the teas before administration to the participants. Blood samples collected before consumption of the tea or tea supplement, and at 1, 2, 4, 6 and 8 hours measured the polyphenols epigallocatechin (EGC), epicatechin (EC), epigallocatechin-3-gallate (EGCG) and epicatechin-3-gallate (ECG). Although polyphenol absorption after taking encapsulated green tea extract was delayed, it proved to be greater than polyphenol absorption from green or black tea consumed as a beverage. This led to the green tea supplement producing a small but significant increase in plasma antioxidant activity compared to black or green tea. The authors conclude that " green tea extract supplements retain the beneficial effects of green and black tea and may be used in future chemoprevention studies to provide a large dose of tea polyphenols without the side effects of caffeine associated with green and black tea beverages.

Guest guest Posted March 5, 2005 Report Share Posted March 5, 2005 Hi Al: Well one way to try to find that kind of information is to ask the author(s). Sometimes the study abstract will have an email address link specifically supplied as a contact method. Other times, when such a link is not supplied, but you have the names of the authors, you can usually determine the academic institution where they work and find their email address, or that of the department, by going to the institution's website and clicking on 'faculty' or 'departments'. You don't have to tell them that you aren't the chief nutrition epidemiologist at one of the world's most prestigious universities! (But of course don't lie to them either). In my experience about half will be happy to help without demanding to know who you are. If you find out the source, for either the blueberry or green tea extract, please come back and let us know. The supplier is likely to be delighted to find a new outlet for his product. Good luck. Rodney. --- In , " Al Young " <acyoung@r...> wrote: ....................

Guest guest Posted March 6, 2005 Report Share Posted March 6, 2005 It's nevertheless suggestive and the very fact that the AJCN bothers with it indicates that it's worth our attention. > 14 men and 15 women is too small of a sample to conclude anything...... > > > on 3/5/2005 5:07 PM, Al Young at acyoung@... wrote: > >> December 10, 2004 >> >> Drinking tea not as beneficial as taking green tea supplements >> >> A study published in the December 2004 issue of the American Journal of >> Clinical Nutrition (http://www.ajcn.org/) found that green tea extract >> supplements offered greater bioavailability of polyphenols and increase >> plasma antioxidant activity compared to tea consumed as a beverage.
