She mentions a diet rich in Protein. Even Supplements like Whey Protein Shakes. I wonder how that extra growth fuel contributes to cancer cell growth. At the very instance kf cell division, there is a small chance of the cell going 'rogue', becoming a cancer cell. In all of our bodies, all of the time. Thankfully the chance is pretty slim, but when I train a lot and eat a lot of protein, then I will have a much higher frequency of cell division. It's what I always wonder when I drink my whey protein after workout, being almost 40. Can my body handle all the growth right?

Protein shakes and workouts wouldn't lead to a higher rate of cell division in the breast, would it? Those cells just go through their natural turnover, influenced mostly by estrogen (which actually has been suspected to play a role in causing breast cancer: https://pubmed.ncbi.nlm.nih.gov/17113977/ )

If anything, you'd expect cancer of the muscle, myosarcoma, to be involved with muscle growth, which thankfully is really rare. Possibly because muscle growth is mostly a matter of hypertrophy of the muscle fibers, not the growth of more muscle cells.

I'd be surprised if the very real health benefits of staying active didn't way outweigh the possibly increased risk of cancer due to increased cell activity.

Isn’t whey, as a milk base, full of growth hormones meant for baby cows?

[loudtieblahblah]

stimulating/activating mTor and IGF-1, needed for muscle growth, will encourage cancer growth where applicable.

overabundance of protein could certainly be at play.

It's particularly damning once you begin to age. To pull a number out of my ass and give a piece of advice we all should focus on reducing mTor by 40.

David sinclair has a bunch of great material on the subject. On his own youtube channel, in talks with others.

[loudtieblahblah]

David Sinclair is right about mTor and IGF-1 but i find him to be really untrustworthy.

he has so much riding on Resveratrol and has put so much into videos, books, gotten grants and so forth, that when studies came out proving Resveratrol isn't the miracle substance he (and many others) purported it to be, he basically just started doubling down and refusing to engage with other scientists calling him out on it.

if you have some time here's a good break down of what's transpired as it's escalated into a bit of social media drama:

David Sinclair also will site highly biased sources if they re-affirm his existing premise. For example, he's been increasingly vegetarian and vegan over the years (and hey - they're good evidence backing up that less meat is mostly a positive).

But he'll site things like Adventist studies on a regular basis.

These studies are shit b/c they're observational

But they're shit moreso because Adventists are vegetarian as a matter of religious faith.

That's their whole angle. They're not going to produce anything that contradicts that worldview.

In fact, Adventists are founders of companies like Kellogs and they're responsible for peddling bad science for decades, like the Ancel keys Seven Nations study that left out countries to make up a bullshit conclusion about Saturated Fats that simplly didn't exist in the data.

This has shaped national nutrition policy and advice for decades. All so they can keep pumping processed products and PUFA's to the public to enrich corporations founded on their religious values.

So to site them, when they aren't doing hard science and trying to use your credentials as a scientist to validate it.. is just bullshit.

Sinclair gets a lot of stuff right but i wouldn't trust him as far as you could throw him.

he doesn't have an alliance to facts anymore. he has his self-interest and his worldview and everything else has to conform to it.

> Resveratrol

That's a pretty outdated view of him. I've seen him admit resveratrol was thematically the right idea, but admittedly not as revolutionary as hoped. Lately he's been more interested in sirtuins, NMN and the like as ways of dealing with the 4 yamanaka factors etc.

I highly recommend his youtube channel where he puts it into pretty easily consumable content

[maerF0x0]

i cannot delete my comment.

But scratch that, he actually seems to be recently digging in trying to claim still being right about resveratrol (:sad_panda:).

Thanks for sharing those links giving a more balanced view.

I don’t think when we work out, we get more cell division. Our muscle fibers get stronger and grow wider (vs adding more muscles).

[ahoka]

I just checked this once, and both can happen, but it depends on the type of exercise.

[ekanes]

Ok thanks!
