#094 Dr. Layne Norton on Building Muscle – Insights on Diet, Training, and Supplements

It's a 100,000-person study out of France from like probably three, four, five years ago.

And I think it was – I want to say it was a 20-year cohort.

And they – one of the big headlines was aspartame increased the risk of cancer.

So I went into the data and looked at it.

So what the headline left out was from –

non-consumers of it to low moderate consumers, it increased cancer by, I think, a relative risk of like 15%, which was significant.

And then the high consumers were not significantly increased risk of cancer.

#094 Dr. Layne Norton on Building Muscle – Insights on Diet, Training, and Supplements

The high consumers were like a relative risk increase of like a non-statistical, like four or 5%.

I'm not aware of anything that's actually carcinogenic that is carcinogenic at a low level and then not at a high level.

Right.

And so I think, again, for me to be convinced by some of this stuff, it would need to be – it's just not consistent.

And it's kind of like – I mean I use this example too.

I'm not convinced that red meat is an independent risk factor for cancer because –

FoundMyFitness
#094 Dr. Layne Norton on Building Muscle – Insights on Diet, Training, and Supplements

These studies are confounded by the fact that red meat typically is kind of a proxy for poor diet quality because most people's sources of red meat in the American diet are fatty.

FoundMyFitness
#094 Dr. Layne Norton on Building Muscle – Insights on Diet, Training, and Supplements

They're processed.

FoundMyFitness
#094 Dr. Layne Norton on Building Muscle – Insights on Diet, Training, and Supplements

The studies looking at unprocessed red meat and cancer risk are all over the place.

FoundMyFitness
#094 Dr. Layne Norton on Building Muscle – Insights on Diet, Training, and Supplements

And when they control for diet quality and there was a really – in my opinion, an elegant study, a cohort out of Canada –

And I think it was by a researcher named Maximova, I want to say.
