Have you ever wondered why cars need regular maintenance? The engine keeps running, fuel is constantly added, oil circulates, and parts gradually wear down. If you wait until the engine warning light comes on or it breaks down, it’s often too late.
Engineers know one thing: real maintenance isn’t about fixing things after they break. It’s about reading the system logs early and keeping everything running smoothly over the long term.
In short: the oil isn’t the engine, but it faithfully records the engine’s history. Engineers use oil analysis to maintain long-term stability.
The logic of the human body is exactly like a car:
Blood tests are like an engine’s pressure gauge—they only tell you what is happening right now. The long-term state of the system is hidden in your hair.
As hair grows, it faithfully records your body’s mineral balance over the past ~90 days, reflecting what you have been eating and your lifestyle. Hair analysis shows:
In other words: your hair acts like a long-term system log, showing whether your body’s “redundancy” is sufficient and whether your diet meets your health goals.
All engineering systems operate in a closed loop:
In short, diet has direction and purpose—it aligns your hair mineral ratios with industry standards to maintain long-term health.
| Car System | Human Body System |
|---|---|
| Engine keeps running Input: fuel, oil Output: heat, exhaust, wear particles |
Body keeps running Input: food, water, oxygen Output: energy, metabolic waste |
| Oil records “running residue” Metal wear Oil oxidation Carbon deposits |
Hair records mineral ratios (~90 days) Na/K, Cu/Se, Cu/Zn, Fe/Mn, Ca/Mg |
| Oil analysis Measures metal content, acidity, deposits Reflects hundreds of hours of engine operation |
Hair analysis Measures mineral ratios Reflects ~90 days of diet and lifestyle |
| Compare to standards Decide whether to maintain early |
Compare to mineral standards Guide dietary adjustments to align hair mineral ratios with safe ranges |
| Closed-loop adjustment → Maintenance Replace oil, filters Adjust lubrication strategy |
Closed-loop adjustment → Diet optimization Adjust diet, supplement missing minerals Keep body in long-term stable, redundant state |
| Mineral Ratio | Standard Range | Diet Guidance |
|---|---|---|
| Na / K | 2.0 – 3.4 | Moderate sodium, sufficient potassium; eat more vegetables, fruits, and low-salt foods |
| Cu / Se | 7 – 30 | Balance copper and selenium intake; nuts, seafood, grains |
| Cu / Zn | 0.083 – 0.25 | Increase zinc or moderate copper; meat, legumes, nuts |
| Fe / Mn | 7.5 – 15 | Supplement iron while ensuring manganese; whole grains, leafy greens, lean meat |
| Ca / Mg | 4.0 – 11.0 | Dairy, leafy greens, nuts help balance calcium and magnesium |
One-Sentence Summary:
Hair records the effects of your diet over the past 90 days, and eating with purpose aligns your mineral ratios with industry standards, keeping your body running long-term, just like maintaining a car.
