Diet for optimal brain health/ performance

Hi, does anyone know what the brain needs and way to determine its optimal nutrition and delivery of nutrition to the brain?

    I don't think we fully know all the nutrients important to brain health but a few that stand out include:

    • Calories - brain matter shrinks in calorie-deficient diets
    • Glucose - at minimum amounts
    • Omega 3

    I'd also advise at hitting 100% of the RDA/AI for nutrients and including plenty of plant-based foods that are rich in phytonutrients. Also, limiting alcohol and avoiding smoking, while getting good sleep and sufficient activity is a good strategy.

    Kind regards,

    Thank you for your advice, this seems consistent with what I read. Calories is a new angle for me though but this is definitely sensible
