Why is the order of the omega3 table so inconsistent - neither alphabetical nor consistently decreasing??? 2A02:8108:9640:AC3:9CA8:8B2:AC86:1470 ( talk) 14:13, 19 July 2021 (UTC)
The sections Health effects and History appear to have been written by two disjunct groups or individuals quoting disparate sources. It makes the article unbalanced and difficult to read. Could an unbiased editor/expert align these two sections? Theking2 ( talk) 09:51, 28 July 2021 (UTC)
This content was recently removed "the brain being 60% fatty acids, of which 84% is omega-3, and less than 2% omega-6". The reason for removal was "Both saturated and monounsaturated fat is more common than omega-3 in the brain" [1] Yet the Wikipedia article also states "A major structural component of the mammalian brain, DHA is the most abundant omega−3 fatty acid in the brain" and elsewhere on the article "The omega−3 fatty acid DHA, also known as docosahexaenoic acid, is found in high abundance in the human brain." We need to know how much omega-3 is in the brain.
Do we have any reliable sources showing that saturated and monounsaturated fat is "more common" than omega-3 in the brain? It is difficult to find exact figures on omega-3 in the brain but this but these sources claim:
The line "the brain being 60% fatty acids, of which 84% is omega-3, and less than 2% omega-6" that was removed [5] was sourced to this article [6] which says "Omega-6 fats comprise <2% of the total brain fatty acids and, hence, are considered as non-functional. Whereas saturated and omega-3 fats make up over 84% of the total brain fatty acids — and they are mandatory for proper brain functions and development" and "DHA alone makes up 40% of the total brain fatty acids. In contrast, EPA is about 250–300 times lower than DHA in the brain and plays more important anti-inflammatory roles in other organs." So the human brain is not 84% total omega 3 is is 84% omega 3 + saturated fat. Unfortunately it does not cite the exact figures.
All sources agree that the human brain is about 60% fat but we need to know what fatty acids make this number. What is the total omega-3 and what is the total saturated fat? The edit summary "saturated and monounsaturated fat is more common than omega-3 in the brain" does not appear entirely accurate. Do you have any reliable references showing that saturated fat and monounsaturated fat is more common than omega-3 in the brain? Psychologist Guy ( talk) 14:10, 3 August 2021 (UTC)
The current lead says "Dietary supplementation with omega−3 fatty acids does not appear to affect the risk of cancer or heart disease", this is sourced to a cancer review from 2006 (the review is not about heart disease). A recent meta-analysis published in 2020 in the Mayo Clinic Proceedings concluded "Supplementation with EPA and DHA is an effective lifestyle strategy for CVD prevention, and the protective effect probably increases with dosage." [9]
The following line in the lead says "Furthermore, fish oil supplement studies have failed to support claims of preventing heart attacks or strokes or any vascular disease outcomes", this sourced to a meta-analysis from 2018 and an older source from 2014. However, a meta-analysis published in 2019 in the Journal of the American Heart Association concluded that "Marine omega‐3 supplementation lowers risk for myocardial infarction, CHD death, total CHD, CVD death, and total CVD". [10]. It seems the lead is citing some outdated information. Psychologist Guy ( talk) 00:52, 4 August 2021 (UTC)
Dr Bernasconi is an employee of the Global Organization for EPA and DHA Omega-3s (GOED), a 501(c)6 not-for profit trade association. GOED’s goals are to increase consumption of omega-3s to adequate levels around the world and to ensure that the industry is producing quality omega-3 products that consumers can trust.
Dr Wiest has been a guest speaker with travel sponsored by DSM Nutritional Products and the Global Organization for EPA and DHA Omega-3s (GOED); and has received funding from GOED to conduct a meta-analysis on omega-3 fatty acids.
Dr Lavie has been a speaker for Amarin Corporation on Vascepa, has consulted for DSM Nutritional Products, and has made an omega-3 educational video at the American Heart Association meeting on November 14, 2016, for the Global Organization for EPA and DHA Omega-3s and also gave a presentation at a GOED-hosted omega-3 conference in Barcelona, Spain, in February 2020.
I'll give this an extra headline, because I think it is important for others that watch this page and later on for the archive. The article is about omega 3s and I would not include studies or recommendations about fish in it. Possible positive effects of fish consumption may have a variety of reasons, one being that less read or processed meat is eaten because it is replaced with fish. Studies about fish consumption are usually observational studies, while studies on omega 3 are usually clinical studies and trials. To my knowledge there is no definitive proof that the effects of fish consumption are mainly linked to omega 3. CarlFromVienna ( talk) 09:11, 21 February 2022 (UTC)
Marion Nestle has written about the food politics surrounding omega 3. I think it should be included in the article. Omega 3s (especially DHA + EPA) are not like any other well-understood nutrient. There is a lot of scientific uncertainty and industry interest at play. For the politics around this nutrient I think no MEDRS are needed and Nestle is a reputable source. Here are some links to her blog:
