Brain Maker by David Perlmutter

He recommends probiotics (these 5–> lactobacillus plantarum,  lactobacillus acidopophilus, lactobacillus brevis, bifidobacterum lactis, and bifidobacterium longum.)

He also recommends “prebiotics”, which are foods that feed good bacteria in a low-carb, high fat, high fiber diet, which also benefits the brain.  I can’t list all of the recommendations here., but basically veggies, low sugar fruit, fermented foods (yogurt, pickled food, kimchie, sauerkraut and others). Healthy fats include extra-virgin olive oil,sesame oil, coconut oil, avodcaos, olives, nuts and nut butters are a few of them. Proteins recommended are whole eggs, wild fish, shellfish and mollusks, grass-fed meat, fowl etc…

Wine (red), tea, coffee and chocolate are good too!

There are many other recommendations and the diet common sense.

I recommend the book in its entirety, not that you need to change your diet entirely, but if you can make easy tweaks to your current habits, so much the better!!  The link for a shortened, $3 Kindle version here.
