> humans often are just not equipped to fight cancer But we are? The immune system is constantly at work killing malignant (or otherwise dysfunctional) cells. Cells themselves have mechanisms to commit suicide (apoptosis) if they are not working properly. It's only when the several mechanisms we have get defeated at the same time (often due to mutations) that cancer can even develop. If you mean, we are not as equipp…

My understanding is there are cancer cells in all adults. They are constantly killed off and never develop into tumors or anything of significance until … they do in some people.

So to say we are not equipped to fight them is incorrect.

Interesting article. One thing to note is that this study seemed to (correct me if I'm wrong) focus on palmitic acid, which can be found primarily in palm oil, but can also be found in meat, cheese, and butter, to name a few other sources.

It's the most common saturated fatty acid. So this isn't just about palm oil, this is about saturated fats causing cancer.

Yet another thing on the cancerogenic pile sigh At some point you have to ask yourself if everything but water gives us cancer.

being alive gives you cancer

Cancer is alive.

That's so weird.

Some part of you decided to go in a different direction. You're not advanced enough to support both. The strain on resources starves you both.

Kind of like a cannibal parasite. That sure sounds like a death metal band.

If palm oil killed cancer cells, would that make it appealing and safe to eat?

If errantly reproducing cells can use a substance, it must be bad: is that the reasoning here?

I would imagine that a source of water also favors tumor expansion. Cut a tumor off H2O and it will shrivel and die.

Is this the same as 3-MPCD? basically any hydrogenated oils would have this, seeing this popping up recently

Take one look at the modern production process for vegetable oil and this sort of effect is starting you right in the face. Palm, Canola, Rapeseed, Soybean, etc, they're all terrible. I avoid this shit like the plague.

Fortunately there's olive oil. Approximately 0.5 liters/month per person at $10/liter for organic extra virgin from Tunisia.

Heard it too causes cancer if you fry it though...

Well, this study passes the "we dumped a bunch of X on cancer cells in a petri dish and they did a funny thing" red flag test. Xenographs (implanting human cancer cells into mice) have their own caveats (the immune system is almost always severely compromised), but this seems like a cool study. I'm no expert on oral cancers however. Curious to see the implication of the neuronal cells here, I'm looking forward to rea…

Cancer cells can consume multiple energy sources, not exactly news here. Concluding that dietary palmitic acid is a problem is questionable. Palmitate is produced endogenously and dietary palmitic acid does not even influence tissue concentration [1]. [1]: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5682332/#B81

> Palmitate is produced endogenously and dietary palmitic acid does not even influence tissue concentration [1].

If there's no uptake by tissue, then wouldn't the tumor have a plentiful energy source once it vascularizes? (Assuming they can metabolize palmitic acid)

Who sponsored this study?

"Big Coconut" and the Keto Kids.

I suggest you read Good Calories, Bad Calories by Gary Taubes before spending more time mocking keto. Ketogenic diets have lots of backing in science and have changed many lives and posts like these can be very hurtful.

We have selective pressure to survive cancer for the first 40 years of our life (and not just barely survive but be unhindered by it). After that there are more subtle selective forces at work: having grandparents that are in good health and helping find food or care for children can certainly improve your survival chances. And of course the machinery we have developed to survive the first 40 years doesn't suddenly stop working after that.

But you're right insofar as there's fairly little selective pressure to prevent cancer over the entire lifespan of a human. We probably could have much better protection from cancer, but the energy investment for that isn't worth it from an evolutionary perspective.

I don't know how to quantify it, but having healthy grandparents in the picture is a survival advantage.
