Probably this one: https://brainenergy.com/

I've read it, it's quite good and full of citations. I've seen a number of studies since it came out that support it as well.

If you like that, also check out "This is Your Brain on Food" which overlaps with much of the content there, but with a bit more of a focus on the gut brain connection.

Change Your Diet, Change Your Mind is another book on these topics which is rather comprehensive and compelling.
