What you eat every day not only affects your weight and energy but also writes a record in your body. Scientific studies show that hair faithfully records the minerals and dietary effects of the past 90 days. Most people do not notice this, eating randomly while the body’s “log” is quietly tracking deviations.
The body works like an engine, continuously running:
Blood tests only show the current state, while hair reflects the actual status over the past 90 days.
Hair grows and records mineral ratios:
Each ratio shows the long-term effect of diet and is not affected by short-term meals or stress.
| Car System | Human Body |
|---|---|
| Engine running Input: fuel, oil Output: heat, exhaust, wear particles |
Body running Input: food, water, oxygen Output: energy, metabolic waste |
| Oil records residues metal wear, oxidation, carbon deposits |
Hair records mineral ratios (~90 days) Na/K, Cu/Se, Cu/Zn, Fe/Mn, Ca/Mg |
| Oil analysis reflects past engine operation |
Hair analysis reflects dietary and mineral intake over 90 days |
| Compare to standard decide if maintenance is needed |
Compare to mineral standards adjust diet to keep ratios in safe range |
| Closed-loop adjustment change oil, filters, adjust lubrication |
Closed-loop adjustment adjust meals, supplement minerals, maintain body stability |
| Mineral Ratio | Standard Range | Dietary Guidance |
|---|---|---|
| Na / K | 2.0 – 3.4 | Moderate sodium, enough potassium, more vegetables and fruits, reduce salt |
| Cu / Se | 7 – 30 | Balance copper and selenium: nuts, seafood, whole grains |
| Cu / Zn | 0.083 – 0.25 | Increase zinc or moderate copper: meat, legumes, nuts |
| Fe / Mn | 7.5 – 15 | Ensure iron and manganese intake: whole grains, leafy vegetables, lean meat |
| Ca / Mg | 4.0 – 11.0 | Dairy, leafy vegetables, nuts to balance calcium and magnesium |
