One score, twelve inputs, visible limits.
HBI brings eight weighted food-data dimensions and four bounded adjustments into a single directional beta number. Open the detail to see the inputs, and treat the result as a learning tool rather than a verdict.
Three taps to a score
Log a food
Search 3,022+ foods and tap a serving. No barcodes to hunt, no macros to memorise — just find it and go.

One directional 0–100 beta number summarizes how that food performs under the current model.

Eight dimensions, four adjustments.
Foundational nutrition contributes 30%. Compound and pathway-related inputs contribute 58%. Processing and risk act as bounded modifiers. Those weights are product choices awaiting external calibration.

Bars show each dimension’s weight relative to the heaviest single input, pathway-related research signals at 20%. Tier 3 dimensions are applied as ± modifiers, not fixed percentages.
What the score means.
Every score lands in one of six directional bands. The colour is the shorthand; the number gives you a little more detail.

Strong result in this model
- Balanced55–69
Several strengths in this model
- Building40–54
Useful in a varied day
- Limited25–39

Look for something to add
Your daily score.
Your day rolls up every food you log, weighted by portion — then rewards variety and colour, and gently discourages a one-note diet.
Diversity bonus
Eat more distinct foods across the day and your score lifts — variety is a signal of a resilient diet.
Colour-spectrum bonus
Hit more colour groups — eat the rainbow — and you unlock a wider spread of phytochemicals.
Balance penalty
If a single food category dominates the day, a gentle penalty nudges you back toward balance.
A day that hits the rainbow and eats broadly lands high — like this.
The model uses the strongest three pathway inputs.
This is an explicit scoring choice: the pathway dimension averages the strongest three current inputs rather than all eight. It does not mean those pathways were measured in a person or that a clinical outcome is expected.
