Relationship to dairy fat and CVD risk

Pentadecanoic acid is a poor biomarker of dairy fat as it is present in dairy fat at only 1.0% or less [1]. Rapeseed oil (canola) contains both pentadecanoic acid and heptadecanoic acid, and cabbage and cucumbers also contain pentadecanoic acid in small amounts. With this one can find any food with a tiny amount of pentadecanoic acid (under 1%) and then try and link it to lower CVD risk. It is unlikely pentadecanoic acid has any effect at this trace level. It is not like palmitic acid or other saturated fatty acids that are present in foods at 20%, 30% or 40%+ which have been shown to have an effect on CVD risk.

Claiming pentadecylic acid will bring about a reduction in CVD is not supported by strong evidence. The review paper cited admits that "Study limitations include the inability of the biomarkers to distinguish different types of dairy foods and that most studies in the meta-analyses (including our novel cohort study) only assessed biomarkers at baseline, which may increase the risk of misclassification of exposure levels." [2]

It seems the above review paper is being cited on social media platforms by the low-carb community who are claiming it refutes dietary guidelines that are telling people to limit dairy fat consumption. However, this is very weak evidence. It does not overturn dietary guidelines. Psychologist Guy (talk) 17:46, 18 April 2023 (UTC)[reply]

If you know the area and see something misleading in the article, please remove the content! That kind of correction happens frequently. If you think that the sentence is an over statement, then you can rephrase the section such as "It has been claimed that ....", thus alerting readers. The very best response is to cite a more authoritative source. The main thing is to act.--Smokefoot (talk) 19:15, 18 April 2023 (UTC)[reply]

After Psychologist Guy's useful edits, the article has the balance of removing potential hype from preliminary research, adhering to existing dietary guidelines, and yet citing two reviews of biomarker evidence. The Imamura and Trieu publications were multinational studies involving biomarker experts, so carry some weight, but those reviews were on preliminary dietary studies, leading to a conclusion of weak evidence. With this edit, we can further state balance that "In reviews of preliminary dietary research, higher circulating concentrations of pentadecyclic acid were associated with a lower risk...".

I agree with you that pentadecanoic acid isn't a useful biomarker for dairy. It is for fiber, however. Most serum pentadecanoic and heptadecanoic acid is created by gut biota chowing down on fiber.

I think the evidence of the health benefits are pretty compelling. I just think the benefits come from consuming fiber, not dairy. 2600:1700:83E0:736F:CD76:B0EE:15F7:EAF (talk) 03:09, 18 June 2024 (UTC)[reply]

Propose we move (rename) back to original pentadecanoic acid

Propose we move (rename) from pentadecyclic acid back to the original pentadecanoic acid. Most/all of the articles refs call it pentadecanoic acid, which is also the IUPAC name. No evidence given that pentadecyclic is the "common name" in any context, (it may be a non-systematic name). Also the discussion referred to in the 18 Oct 2020 move comment : [3] does not seem to conclude that this article should have been renamed. - Presumably somehow we swap article with redirect. Any objections ? - Rod57 (talk) 14:12, 22 July 2024 (UTC)[reply]
