Your diet is quietly inflaming your brain — and your blood markers show the impact.
Most people think of diet-driven inflammation in terms of the gut or the waistline. Less obvious is what a poor diet does to the brain. Four biomarkers atry tracks make that impact measurable, not theoretical.
What a poor diet does to your blood
- hs-CRP — elevated, watch. Processed food and sugar drive systemic inflammation.
- Omega-3 Index — low. Most Western diets sit well under the 8% target.
- Homocysteine — elevated, watch. B-vitamin depletion from refined grains is a common driver.
- Zinc — suppressed. Refined food strips it, and it's needed for neurotransmitter synthesis.
atry flags all four against optimal ranges, not just the standard lab range. As always, discuss any flagged results with your prescribing physician.
Intervention 01: Omega-3, 2g EPA/DHA daily
This is the clearest dietary lever for lowering hs-CRP, backed by dose-response trial data.
- Omega-3 index target: above 8% for optimal cardiovascular protection.
- EPA + DHA dose: 1,200mg reduces CRP in a cardiometabolic dose-response meta-analysis.
- hs-CRP: reduced across 148 pooled trials in an umbrella meta-analysis.
Protocol: 2g EPA/DHA daily — oily fish 2–3x/week.
Intervention 02: Small swaps, measurable shift
- Wholegrains, not refined — preserves the B-vitamins, magnesium, zinc, and fibre that refined grains strip out.
- Cut added sugar — blood sugar spikes drive cortisol and downstream inflammatory signalling.
- Zinc-rich foods — shellfish and lean meat support neurotransmitter synthesis directly.
- Daily probiotic foods — the gut produces roughly 90% of the body's serotonin.
Intervention 03: Omega-6:3, the ratio that matters
Quantity isn't the lever on inflammation. Balance is.
- Western diet ratio: 15–20:1, typical intake driven by industrial seed oils.
- Target ratio: 4:1 or lower — the evolutionary baseline for balanced inflammatory signalling.
- At a 4:1 ratio: associated with a 70% reduction in mortality for secondary coronary heart disease prevention.
Protocol: cut seed oils — oily fish 2–3x/week — wholegrains over refined.
