How Nutrition Affects Your Brain
Your brain consumes 20% of your body's energy despite being only 2% of your body weight. What you eat directly impacts:
Neurotransmitters
- Dopamine: Motivation and reward (affected by protein)
- Serotonin: Mood and focus (affected by carbohydrates)
- Acetylcholine: Memory and learning (affected by choline)
- Norepinephrine: Alertness (affected by tyrosine)
Brain Structure
- Omega-3 fatty acids: Build brain cell membranes
- Antioxidants: Protect neurons from damage
- B vitamins: Support neurotransmitter production
- Iron: Essential for oxygen transport to the brain
Energy Levels
- Complex carbs: Provide steady glucose for brain fuel
- Protein: Prevents blood sugar crashes
- Healthy fats: Support sustained energy release
