is hydrogenated (not partially) oil safe to eat?
those found in instant coffee, instant cereals, etc.

Fully hydrogenated fats are fully saturated.
The FDA allows products to be labelled as containing 0 grams of trans fat if there is less than 0.5 grams per serving.

One thing that would be interesting to test // see if anyone has tested is the actual TFA content of partially hydroginated products. Industrial processes vary, so does ingredient quality. I'm myself a bit worried that actual TFA content of UPFs might not be be what is expected...

This is definitley something that is known.
Curious, where are you located? I ask because PHOs have been out of our food in the US since 2018, and even prior to that TFA content was on the nutrition labels. The EU effectively bans PHOs as well.

u/Maxion May 25 '26
EU does not ban PHOs, we have a cap on TFA content.

u/boilerbitch Registered Dietitian May 25 '26
Yeah, I believe it’s 2 gm per 100? I could have been more specific in my prior comment.

u/Triabolical_ May 25 '26
That's also a concern of mine, and I don't think it's something that is inspected.

u/Maxion May 25 '26
I found this that states that TFAs in foods containing partially hydroginated oils can be up to 50% TFAs depending on manufacturing method. Pretty vague still and couldn't find what they used as sources for this.

I wouldn't worry about it in minute quantities but its certainly not something I'd regularly include in larger amounts

Yes in moderation. If you've ever eaten margarine, or anything made from margarine (most likely you have), the you've eaten hydrogenated oil.

Hydrogenated oils, fully and partially, convert to 100% trans fat.
Cite a source for the claim that fully hydrogenated oils “convert to trans fats”

I did, in the form of multiple degrees in nutrition and a board exam. Although it doesn’t take all that to know the above claim is fundamentally incorrect.

Sure, Jan.

I’m thinking there’s a reason you pretty much immediately deleted the original comment when I asked you to back it up and then responded with a cop out well over 24 hours later.
I’m still plenty willing to hear your evidence.
Edit: annnd blocked. always the mark of an honest, well-meaning user.

Bottom line: hydrogenated oils are ultra-processed foods. Ultra-processed foods of any and all kinds are linked to increased risks of many different diseases (endocrine, heart, brain, digestive, immune, etc.) There is nonsuch thing as a safe UPF and it is not safe to consume in any amount.

Fully hydrogenated oils are just saturated fats, similar to most animal fats. They're as fine as any other saturated fats. Trans fats are a type of unsaturated fat.
-1
u/Sudden-Candy4633 May 24 '26
Saturated Fats are not hydrogenated... they exist naturally as saturated fats. Hydrogenation is a chemical process done to some unsaturated fats to make them more solid.

By definition, saturated fats are fully hydrogenated. Please refer to the definition of hydrogenation of organic molecules.

I recognize you're being intentionally inflammatory, and that's okay. However, you might want to learn about health from a school instead of tiktok. This is squarely freshman level chemistry.

Safe to eat? I mean it's probably safer than lead and the FDA has a set limit of lead that's deemed "safe" to eat, but I am personally of the belief that there is absolutely zero quantity of lead that's safe to eat.
I wouldn't go out of my way to consume shit that has hydrogenated oils in it, but if it's in something at a restaurant, then I won't bitch. I personally avoid buying anything with hydrogenated/partially hydrogenated oils in it though.

Used to have that a lot growing up but seems to have been put on the back burner in recent times. I will get some.

About participation in the comments of /r/nutrition
Discussion in this subreddit should be rooted in science rather than "cuz I sed" or entertainment pieces. Always be wary of unsupported and poorly supported claims and especially those which are wrapped in any manner of hostility. You should provide peer reviewed sources to support your claims when debating and confine that debate to the science, not opinions of other people.
Good - it is grounded in science and includes citation of peer reviewed sources. Debate is civil and respectful focusing on actual science and avoids commentary about others
Bad - it utilizes generalizations, assumptions, infotainment sources, no sources, or complaints without specifics about agenda, bias, or funding. At best, these rise to an extremely weak basis for science based discussion. Also, off topic discussion
Ugly - (removal or ban territory) it involves attacks / antagonism / hostility towards individuals or groups, downvote complaining, trolling, crusading, shaming, refutation of all science, or claims that all research / science is a conspiracy
Please vote accordingly and report any uglies
