And there was no food or olive oil or food group or eating more or less meat that changed the relationship between the Mediterranean diet and dementia risk.

So what that tells me is it's much more about whole foods, they're nutrient dense, rather than avoiding any, you have to eat

You have to consume lots of olive oil, right?

Or you have to restrict meat.

Because if those things are eaten in the context of all this other stuff, it's really that bigger context of diet quality and nutrient density that really matters.

So the parts of diet that I think about are...

There's three, so there's energy, there's nutrients, and then there's overall dietary pattern.

So one of the confounding things about that trial I told you about, the mind diet versus caloric restriction, is you're like, well, the mind diet should win out, right?

How does caloric restriction do just as well?

And in the kind of average population,

we tend to have some issues with metabolic health and have been in a state of chronic energy excess for some period of time.

There's been some very nice studies that have looked at brain aging and brain volume or brain reserve across different populations.

There was one group that looked at

different tribes in Bolivia, the Bolivian Chimane, who are a hunter-gatherer group, the Musetan, who are an intermediate group between the Chimane and a standard industrialized group, and then industrialized humans in the US and Europe.

What they found is this bell-shaped curve between energy availability and brain volume.

In general, brain volume, the more the better, we think.

And so if you're chronically calorically restricted, your brain is smaller because you just don't have the resources to invest in the structure and to maintain it.

At the other end, you see the same thing.

So if you're chronically in a chronic state of caloric excess, you also tend to have a smaller brain on average.

And this is related to metabolic disease and potentially diabetes.
