And what comes with it, higher levels of inflammation, high blood pressure, things like that, that we know can negatively impact the brain.

So the most important thing, and I think this is where some of the benefits of caloric restriction happened in that trial compared to the MIND diet, was that people's cognition improved just because they decreased their energy intake to a point that was...

more, you know, was essentially kind of what their brain kind of needed, you know, kind of supported their overall physical health, which then affects, you know, cognitive health and brain volume.

and brain function.

So the first thing to do is to make sure that you're eating enough, but not too much.

And that's very simplistic, but energy is really critical.

Energy availability, not too low, not too high.

Then the next thing that you need is nutrients.

We know there are several critical nutrients related to cognitive function and risk of dementia.

The ones that we have the best evidence for are vitamin D, iron, omega-3 fatty acids, the B vitamins involved, and the B vitamins involved in methylation.

So particularly B12 and folate, also potentially B6 and riboflavin, although that might depend a little bit more on the individual.

Then there are some other nutrients that have some pretty good evidence for them.

So many of the antioxidant polyphenols, things that you get from berries, coffee, tea, chocolate, the carotenoids that make things orange, yellow, and red, lutein, zeaxanthin, astaxanthin, if it comes from seafood, that's what makes shrimp and salmon pink.

And then some other aspects like dietary fiber seems to have some benefits as well.

Magnesium is absolutely in there too.

Magnesium, zinc, then there's some of the structural lipid components, things like choline and ethanolamine that you might get from nuts and seeds or eggs.

They have some slightly less evidence, really when you're looking at brain changes over time and dementia risk, but they certainly do seem to be related to cognitive function.

So there are some studies that show that those who have lower magnesium intakes tend on average to perform less well on some cognitive function tests.

So all of those do seem to be important.

So again, I think we're often tempted
