You Are What You Eat (And Think)

Your brain consumes 20% of your daily calories. Feed it well.

Brain-Boosting Foods

Omega-3 Rich:
  • Wild salmon, sardines, mackerel
  • Walnuts and flaxseeds
  • Critical for brain cell membrane health
Antioxidant Dense:
  • Blueberries (the superfood that lives up to the hype)
  • Dark chocolate (85%+ cacao)
  • Green tea
Choline Sources:
  • Eggs (especially yolks)
  • Liver
  • Critical for acetylcholine production

Meal Timing for Focus

Morning: Protein and fat focused
  • Delays blood sugar spikes
  • Sustained energy without crashes
Afternoon: Moderate carbs added
  • Replenish glycogen
  • Support serotonin production
Evening: Complex carbs
  • Promote relaxation
  • Support sleep quality

Supplements Worth Considering

  • Omega-3s (if not eating fatty fish regularly)
  • Creatine (yes, it's for the brain too)
  • Vitamin D (if you're indoors a lot)
  • Magnesium (most people are deficient)
  • What to Avoid

    • Seed oils and processed foods
    • Excessive sugar
    • Too much caffeine (after 2pm)
