Don’t tell that to the people in Sardinia ( a blue zone) who literally drink olive oil. Throw it over all food then dip there bread in it.

I’m specially wording about hydrogenated oils used topically; especially Squalane (which is an ingredient that I understand can now be produced without harming sharks and that I am otherwise interested in).

I have the impression that one of the bad things about hydrogenated oils is that they are somehow bad for cell membranes (perhaps causing or contributing to performability and perhaps overall weakness or breakdown in cell membrane integrity). I also have the vague impression that perhaps for various reasons, hydrogenated oils, rancid oils, low-quality oils, petroleum oils etc might be generally “aging” in some way or another (perhaps related to oxidation or something else).

Also, if hydrogenated oils in cosmetic products is an issue, I would image that there would be a lot of words on the ingredient lists (like “Squalane”) that we would need to look out for (and lots of products on my self that I like would need to be thown out. . perhaps without a good replacement) , so I hope that I am misguided in my concerns.

Hmm… could it be maybe that processed foods which aren’t healthy that contain vegetable oils are causing the increase in cancer and heart disease and the increase in these diseases has nothing to do with vegetable oils?

most likely Dan is a pr0-establishment troll who works for monsanto and the like, why else would he be contributing anything to this blog?

Both are still very high in polyunsaturated fats and there are much healthier alternatives for oils, even if those come from organic sources.

Coconut oil or sustainable palm oil both work great

Yes 🙂

Sesame is ok! Or, it is according to Dr Cate. She is the first Dr I’ve ever heard comment on this issue of “bad oils” that we’ve been told are good for us. https://drcate.com/the-hateful-eight-enemy-fats-that-destroy-your-health/

yeah I saw that tuna was a “small fish” and had wanted to correct it. Thanks for your well-written comment on this.

A ‘test’ I showed my grandchildren: place a pat of margarine on a plate, a pat of butter on another and set outside. Flies will NOT go near the margarine! If flies won’t have anything to do with margarine, why would I put it in my body?

*I lost a leg to cancer at age 11. Did the cancer come from mom switching from butter to margarine (because it was cheaper)? I have no idea. All I know is, my dad had many medical issues AFTER eating margarine on a regular basis. Again, I cannot PROVE the margarine caused all this. I’m now 62 years of age and moderately healthy. I eat pretty healthy. I do enjoy fried catfish nuggets occasionally. Other than that, I’ve pretty much done away with fried food.

I’m wondering this too. My husband uses it in stirfry, and I have used it to make salad dressing.

I read your well written article via a link in an article from my Medium membership, and agree with most of it.

There is one item however, that you need to tend to in the article that is of importance: you mention that Tuna is a small species of fish that provides healthy benefits. This is largely incorrect. Tuna is a large, top-level predator, and as such contains many toxins in its meat including mercury, due to bioaccumulation. Most Tuna should be avoided for this fact alone. The other side of this is that the larger species are in such population decline due to overfishing, that they are nearing endangered species territory.

Blackfin Tuna, a smaller fish in comparison to Yellowfin, Skipjack, or the endangered Bluefin, is a healthier and currently sustainable option if you enjoy Tuna.

Also, sustainably caught, wild Pacific or Atlantic Salmon are healthy Omega-3 options for consumption, but be sure to stay away from farmed salmon, which are loaded with hormones and antibiotics; fish farming also accounts for negative impacts upon native wild species populations.

Thanks again for a great read, and cited sources. My apologies for not providing my own in my reply, but a quick bit of online research will easily support the claims.

It’s up to each of us to inform ourselves of our consumption habits regarding our personal health, as well as the health of the planet and it’s myriad of incredible species we share it with.

Kind regards…

I see how that could be unclear. Basically, only a small amount of the fat in the body is polyunsaturated, and that fat in the body is a mix of Omega-3 and Omega-6 fatty acids. We often eat much more omega-6 based fat in a modern diet so we’re often low on Omega-33 anyway, and many processed foods use that fat in place of monounsaturated or other types of fats. In other words, it’s easy to get plenty of polyunsaturated omega-6 fats even without eating processed foods so I find it important to focus on consuming more Omega-3 and other types of fats and minimizing vegetable oils.
