Why does so many people here hate PUFAs?!

[softlysoftly]

One big problem is this attempt to connect PUFAs to heart disease, the actual outcome evidence does not support it; in fact, it like strongly supports the opposite.

Replacement of SFAs with PUFAs has a consistent protective effect on CVD.
https://pubmed.ncbi.nlm.nih.gov/30019767/

A systematic review of the effect of dietary saturated and polyunsaturated fat on heart disease - PubMed

Reducing saturated fat and replacing it with carbohydrate will not lower CHD events or CVD mortality although it will reduce total mortality. Replacing saturated fat with PUFA, MUFA or high-quality carbohydrate will lower CHD events.

pubmed.ncbi.nlm.nih.gov

This is likely due to a few different mechanisms, the first being that SFAs reliably increase blood LDL cholesterol levels and by default Apolipoprotein B (ApoB) which is thought to be a major factor contributing to atherosclerosis and CVD (more discussion on this later). Replacement of SFAs with PUFAs (particularly omega-3 PUFAs) has been shown to have a protective effect on CVD, likely by lowering LDL, ApoB, reducing inflammation, and various other proposed mechanisms.

https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2719153/

This even holds true in a meta-analysis of CVD risk and linoleic acid intake.

Dietary linoleic acid and risk of coronary heart disease: a systematic review and meta-analysis of prospective cohort studies - PubMed

In prospective observational studies, dietary LA intake is inversely associated with CHD risk in a dose-response manner. These data provide support for current recommendations to replace saturated fat with polyunsaturated fat for primary prevention of CHD.

This meta-analysis suggests that dietary and non-dietary intake of n-3 polyunsaturated fatty acids reduces overall mortality, mortality due to myocardial infarction, and sudden death in patients with coronary heart disease.

pubmed.ncbi.nlm.nih.gov

While randomized controlled trials are the gold standard in research, we cannot neglect their limitations, especially when it comes to subject number and time duration.

Further, even when specifically looking at omega 6 PUFAs there is a protective effect when replacing SFA with them.

www.nature.com

In this cohort study, those with higher blood levels of omega 6 PUFAs had a 50% lower risk of a CVD incident during a 35 year follow up.


TLDR: All of this to bring it back to the topic that saturated fat supposedly is good for you while PUFAs are bad. There is no hard evidence to back this up. People attempt to draw a mechanistic link between PUFA oxidation and CVD while ignoring the fact that saturated fat has a much STRONGER mechanistic link to CVD, which is backed up by actual outcome data in humans. Meanwhile, we not only have mechanistic data showing saturated fat can damage the arterial wall, but we also have outcome data and MR data across multiple lines of evidence showing saturated fat and LDL are most likely causal for CVD. There is no evidence that I am aware of demonstrating that PUFAs are casual for CVD, and if anything, they likely have a protective effect.

also im sure some of these studies assume it reduces risks of cardiovascular disease because it reduces total serum cholesterol level which they associate with cvd risk, not because the people studied were dying

This trial showed a "22% higher death rate for each 30 ng / dL reduction in cholesterol" when saturated fat was replaced with linoleic acid

Saturated is not safe as you age, although some is necessary for good hormonal levels

PUFA main problem is they oxidize easily. This seems to be an inherent chemical property. The idea then is they develop free radicals, are ingested, digested, absorbed, and there are enough free radicals in the bloodstream distributed across the body to cause damage

Vegetable oil consumption has been correlated with lowered testosterone

A systematic review of the effect of dietary saturated and polyunsaturated fat on heart disease - PubMed

Reducing saturated fat and replacing it with carbohydrate will not lower CHD events or CVD mortality although it will reduce total mortality. Replacing saturated fat with PUFA, MUFA or high-quality carbohydrate will lower CHD events.

pubmed.ncbi.nlm.nih.gov

This is likely due to a few different mechanisms, the first being that SFAs reliably increase blood LDL cholesterol levels and by default Apolipoprotein B (ApoB) which is thought to be a major factor contributing to atherosclerosis and CVD (more discussion on this later). Replacement of SFAs with PUFAs (particularly omega-3 PUFAs) has been shown to have a protective effect on CVD, likely by lowering LDL, ApoB, reducing inflammation, and various other proposed mechanisms.

In this cohort study, those with higher blood levels of omega 6 PUFAs had a 50% lower risk of a CVD incident during a 35 year follow up.


TLDR: All of this to bring it back to the topic that saturated fat supposedly is good for you while PUFAs are bad. There is no hard evidence to back this up. People attempt to draw a mechanistic link between PUFA oxidation and CVD while ignoring the fact that saturated fat has a much STRONGER mechanistic link to CVD, which is backed up by actual outcome data in humans. Meanwhile, we not only have mechanistic data showing saturated fat can damage the arterial wall, but we also have outcome data and MR data across multiple lines of evidence showing saturated fat and LDL are most likely causal for CVD. There is no evidence that I am aware of demonstrating that PUFAs are casual for CVD, and if anything, they likely have a protective effect.

i dont know what any of this means sorry

 

[SteveRogers]

You are fucking stupid.

Keep eating PUFAs though, please nigga.
While you rot from the inside out, I’ll be happily eating all of the saturated animal fat possible, literally slurping blood and fat straight from the source

Muh “Why does so many people here hate PUFAs?!” - it’s “do” and it’s because they’re extremely toxic, poison.

 

[SteveRogers]

Data > feelings

A true slave.

[softlysoftly]

because they’re extremely toxic, poison

provide the proof show the evidence to dispute what I posted
I made claims then like backed it up with evidence now why can't you do the same?

A true slave.

I am slave to being an objective thinker

goofy charts showing weak correlations
did you know that like both murders and ice cream sales go up in the summer I guess ice cream must be causing murder huh? no its just correlation and correlation =/= causation

these small molecule groups are mostly cope, you eat 100 you don’t even think of that fuck with you. If you think that you need to be autistically obsessed with nutrition just to be somewhat healthy it over.

If you exercise that is something more associated with stopping heart disease than any fatty acid or cope extract.

imo a flavorless oil goes against the point of cooking with an oil.

I guess if you want to add calories while adding nothing else? or if you like peanut butter. Lol at this retard argument when ray peat people refuse to eat a single walnut and avoid chicken.

it's ok bro just eat the seed oil that was invented 100 years ago, heat treated 5 times, deodorized and put into plastic containers and rest happy knowing that shlomo has your back with his studies

I am an incel who need to feel superior to others, and persecuted for that, despite having nothing, so sometimes I will pretend I avoid eating out because of pufa instead of having no money.

One big problem is this attempt to connect PUFAs to heart disease, the actual outcome evidence does not support it; in fact, it like strongly supports the opposite.

Replacement of SFAs with PUFAs has a consistent protective effect on CVD.
https://pubmed.ncbi.nlm.nih.gov/30019767/

A systematic review of the effect of dietary saturated and polyunsaturated fat on heart disease - PubMed

Reducing saturated fat and replacing it with carbohydrate will not lower CHD events or CVD mortality although it will reduce total mortality. Replacing saturated fat with PUFA, MUFA or high-quality carbohydrate will lower CHD events.

pubmed.ncbi.nlm.nih.gov

This is likely due to a few different mechanisms, the first being that SFAs reliably increase blood LDL cholesterol levels and by default Apolipoprotein B (ApoB) which is thought to be a major factor contributing to atherosclerosis and CVD (more discussion on this later). Replacement of SFAs with PUFAs (particularly omega-3 PUFAs) has been shown to have a protective effect on CVD, likely by lowering LDL, ApoB, reducing inflammation, and various other proposed mechanisms.

https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2719153/

This even holds true in a meta-analysis of CVD risk and linoleic acid intake.

Dietary linoleic acid and risk of coronary heart disease: a systematic review and meta-analysis of prospective cohort studies - PubMed

In prospective observational studies, dietary LA intake is inversely associated with CHD risk in a dose-response manner. These data provide support for current recommendations to replace saturated fat with polyunsaturated fat for primary prevention of CHD.

Omega 3 PUFAs do appear to reduce risk in RCTs.

N-3 polyunsaturated fatty acids in coronary heart disease: a meta-analysis of randomized controlled trials - PubMed

This meta-analysis suggests that dietary and non-dietary intake of n-3 polyunsaturated fatty acids reduces overall mortality, mortality due to myocardial infarction, and sudden death in patients with coronary heart disease.

pubmed.ncbi.nlm.nih.gov

While randomized controlled trials are the gold standard in research, we cannot neglect their limitations, especially when it comes to subject number and time duration. Compare this with the cohort studies on the effects of replacing SFA with PUFA that demonstrate quite a powerful protective effect of replacing SFA with PUFA that appears to be dose dependent.
https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6451787/

Further, even when specifically looking at omega 6 PUFAs there is a protective effect when replacing SFA with them.
