Talk:Grape seed oil

message: I suffer because of blurred terminology...Should first things not be first, "What  ..(the subject under discussion  is),should be first and foremost be defined, we should say what we are we talking about...before thundering away and describe all sorts of detail, I humbly suggest (and beg) that the DEFINITION must ALWAYS the introductoryline, meaning the subject must initially be circumscribed.  I still don't know whether the term "grapeseed" and "grapeseedextract is the same...
Two suggestions: I would explain the "Treatment" section better - are these folk remedies?  Proven medical benefits?  How are they applied? - and I would rearrange the sections, so that "Treatment" and "Medical Information" are together, and "Modern Uses" is listed first.  Otherwise, very good stuff.

message: i agree with Securiger below. i'm very worried about much of the so-called facts on this page too.it's not cited and many other sources contradict the info mentioned here.i labelled dubious sentences where appropriate and asked for some sources to prove the info there.my role here?i added a link that supports the little (but confirmed) info i providedGrandia01 (talk) 00:49, 2 January 2008 (UTC)

Studies have shown that grape seed-derived oligomeric proanthrocyanidins (OPC) prevents cardiovascular disease and can counteract the negative effects of high cholesterol on the heart and blood vessels. OPC's are a set of bioflavonoid complexes that perform as free radical scavengers in the human body. These OPCs can help protect against the effects of internal and environmental stresses (that is, cigarette smoking, pollution, and suporting normal body metabolic processes). The effects are; depressing blood fat, emolliating blood vessels, lowering blood pressure, preventing blood vessel scleroses, dropping blood viscidity and preventing thrombus formation (a type of platelet clot).

thread_title:  Treatment for 

message: There are a number of website "health" newsletters that claim GSO is unhealthy as a frying oil. I see nothing on the talk page about that. Hopefully someone will address it.ChicagoLarry (talk) 22:08, 17 December 2014 (UTC)
thread_title:  Not healthy for frying? 

message: I can't find the paper in the Journal of the American College of Cardiology that this article cites. The number "925-116" in the citation doesn't make sense to me. No 1993 article in the JACC starts on page 925 or page 116. Google for several variations on the article title reveals nothing. Some Google hits have citations like "J Am Coll Cardiol 1993;21:318-20", but again, no such article exists. See for yourself. 
Medline and JACC searches for Nash DT, Nash SD, Grant WD, "grape seed", "grapeseed", and combinations of those terms reveal no articles fitting the citation. I found one Web page that cites something believable: Nash DT, Nash SD, Grant WD. Grapeseed oil, a natural agent which raises serum HDL-C levels. Presented at the American College of Cardiology 42nd Annual Scientific Session, Mar 15, 1993, Anaheim, Calif
I have a feeling that I'll find the abstract of the presentation here: 42nd Annual Scientific Sessions. Anaheim, California, March 14-18, 1993. Abstracts. Journal of the American College of Cardiology. 21(2 Suppl A):1A-578A, 1993 Feb.
Unfortunately, JACC doesn't have supplements from that far back online. I'm deleting the reference and modifying the text appropriately until I can get to the library.
Significant deleted text follows:

message: Grapeseed oil appears to be very high in omega-6 while low in omega-3.  Apparently this is a common problem with the American diet already, and that such an imbalance may cause immune system depression, along with weight gain.  Any verification of this? Jadxia 18:48, 15 February 2007 (UTC)
replies: text: That's usually what "virgin" and "extra virgin" mean - i.e. contains no blended/refined oil (and is therefore 100%). At least, everywhere else except the US it seems. See Olive oil grades Jon (talk) 09:02, 13 January 2008 (UTC)
thread_title:  Grapeseed Oil As Major Fat Source 

message: I've had a go at fleshing out the refs. The Nash study seems unpublished, but should be in their proceedings (seminar presentation). Jon (talk) 11:41, 13 January 2008 (UTC)

message: How long has grapeseed oil been used (particularly for cooking), and what is the historical evidence for this use? Badagnani (talk) 01:55, 9 March 2008 (UTC)
thread_title:  How long has it been used? 

message: Yes it is true, Grapeseed oil is low in Omega-3 fatty acids so it will not supply these to the skin topically or orally to the body. The lack of Omega-3 in our diets is a problem. Omega-3 fatty acids stimulate the manufacture of anti-inflammatory cytokines in the body, which reduca the chance of joint inflammation and inflammation in arteries which can reduce circulation (The so called stroke). Grapeseed oil with a bright green color indicates to me though, that it may have some polyphenol in it, but not as much as from bright red colored skins.  —Preceding unsigned comment added by 66.251.102.206 (talk) 15:42, 1 July 2009 (UTC)

message: There seem to be a lot of unsubstantiated claims in this article, some bordering on bollocks. Can we have a go at either finding citations or removing the claims? Cheers. Jon (talk) 02:39, 15 September 2009 (UTC)
replies: text: Well I seem to be talking to myself, but in case any visiting editors are interested, I think six months is ample time for editors to provide citations for their claims. Since in this time no such citations have appeared (indeed, more unsubstantiated claims have appeared) I have removed them and refactored the article. Echoing folks above, It concerned me that this article is one of the main Google links to come up and yet it is full of health claims with no supporting evidence.

text: Hi! Cheers for the feedback. I'm a bit busy this month but perhaps we can work on the cosmetics angle and include references. Jon (talk) 13:21, 19 August 2010 (UTC)
thread_title:  Unsubstantiated Claims 

message: I looked online for info on the history of this oil, but only found vague statements such as "has been known since ancient times". Perhaps someone is able to dig deeper, beyond the commercial results in the first few pages of a Google search for history grape seed oil. --Chriswaterguy talk 19:00, 27 March 2012 (UTC)
thread_title:  History of grape seed oil? 

message: I refer the honourable future contributor(s) to the discussion c. 2009 entitled Unsubstantiated Claims, above. Please refrain from just adding any old codswallop you read off the back of a bottle of moisturiser into this encyclopaedia article, and if you are making claims about supposed skin- or other health-related benefits, please make sure you have an appropriate reference (and that it isn't a link to a manufacturer's online brochure).
