trans fats. natural vs industrial.

[allrnder]

Hi all.

so is there any update on hydrogenated industrial trans fats HITFA's and naturally occurring trans fatty acids?

My current understanding is that HITFA's should be consumed as little as possible. consuming a tiny amount say 2 or 3g per day from general cooking is ok. Natural occurring trans fats is a good idea to avoid as well but dont have the same effect as HITFA's. So if you are consuming 10% of your calories from animal fats and the natural trans fats in that will be fine.

Any new research papers on this?

I currently only have this> https://www.heart.org/en/healthy-liv...fats/trans-fat

Thanks in advance,.

Last I looked into it ruminant (natural) trans fats are likely healthier than industrial based on different properties but people naturally consume ruminant trans fats at ~1/3 to ~1/2 the value of industrial and thus it's not clear if different health effects are due to the different chemical nature or the fact that people eat less of them. I can provide a reference if desired.

Hi mate. thanks. yeah a reference would be good. i do have one somewhere but its on rats only

Thanks mate. reading now.

Perhaps interesting:

Hey everyone,

1) Thanks Ironwill for alerting me to this thread.

2) The evidence basis for making attempts to completely avoid industrial trans fats (as opposed to keeping them to a low roar at most, of course within a sound overall program) is sketchy. By sketchy, I mean that the majority of the available published data examine industrial TFA intakes that are many times greater than the average. It's entirely possible that iTFAs' adverse effects, like virtually all consumable compounds in the commercial food supply, are only present above a certain threshold. Below this threshold, effects would be biologically neutral, or virtually undetectable & therefore practically meaningless - especially within the context of an otherwise well-constructed diet & lifestyle. Of course, the burning question is what this threshold actually might be. Here's the current state of the evidence, there are still lingering questions & rather wide gaps in the literature: http://www.ncbi.nlm.nih.gov/pubmed/27394654

Unfortunately the full text of this paper is not publicly available. Feel free to email me (support at alanaragon.com) and we can discuss this, since I don't feel good about posting the paper here for everyone to grab; Elsevier has been known to be b1tchy about copyright.

My take: personally I'd avoid iTFAs as much as possible. See for example: https://jamanetwork.com/journals/jam...rticle/2530902
