Clean Diet & Food Sensitivities
Reduce brain fog by removing triggers, then reintroduce foods methodically alongside dual n-back tracking.
Food–brain connection
- Gut-brain axisInflammation from trigger foods can show up as fog, poor focus, or sleep disruption.
- Ultra-processed riskHigher intake correlates with worse cognitive outcomes; whole foods align with better scores.
- Objective checkUse dual n-back scores as a simple readout of mental clarity over time.
Common signs of food triggers
- Brain fog & slow recallMental cloudiness, harder retrieval.
- Focus dropsShorter attention span, more lapses.
- Headaches or sleep issuesMigraines, restless nights, or fragmented sleep.
- Mood shiftsIrritability, anxiousness, or low mood after meals.
Likely food triggers
PrimaryGluten, dairy, processed sugars, and artificial additives.
SecondaryEggs, soy, peanuts/nuts, nightshades, histamine-rich foods, and lectins for some.
2-week elimination (meat-only)
- EatFresh meat/fish and water; simple prep methods.
- AvoidAll plant foods, dairy, eggs, seasonings, sauces, stimulants, and supplements.
- ExpectDays 1–3: withdrawal fatigue/headaches; Days 4–7: stabilizing; Days 8–14: clearer baseline.
Short-term diagnostic only. Hydrate, mind electrolytes, and avoid heavy exertion if you feel unwell.
Reintroduce methodically
- One group at a timeTest 1–2 days, then watch 3–4 days.
- Suggested orderEggs → dairy (butter, then milk/cheese) → gluten-free grains → low-lectin veggies → fruits → nuts/seeds → gluten grains.
- Reset gapsWait 3–4 clear days before the next food if a reaction appears.
Long-term maintenance
- Avoid confirmed triggersEspecially before important cognitive work.
- Favor whole foodsLean proteins, omega-3 fish, olive oil, low-inflammatory vegetables; keep sugars low.
- Support recoverySleep quality, stress management, and gut health practices.
Track what changes
- Daily logMental clarity (1–10), energy (AM/PM), mood, sleep quality, GI notes.
- Performance markerTrack dual n-back scores before, during, and after changes.
