Nutrition Engine
The engine that turns individual nutritional requirements into what someone can actually eat.
ONE starts with the person — their requirements, allergies, restrictions, preferences and nutrient priorities — then produces meal plans, recipes, substitutions and logging your product can present under your brand.
How it works
From the person to personalised food decisions.
This is the core of the product: a clear transformation from nutritional context into experiences users can act on.

Capabilities
Nutrition intelligence, not just food data.
ONE analyses intake patterns and behavioural signals so recommendations improve — while allergies and dietary restrictions remain non-negotiable.
01
Meal planning
Single-day and multi-day plans with breakfast, lunch, dinner and snacks shaped by each user's profile.
02
Macro & micro targets
Calories, protein, carbs, fat and micronutrient priorities — including focus areas such as iron.
03
Allergies & diet types
Respect what users must avoid, while still adapting to preferences and dislikes.
04
Recipe recommendations
Recommend recipes that fit requirements — with tenant catalogs under your control.
05
Preference learning
Use history and behaviour so future plans and recommendations feel more personal over time.
06
Substitutions & progress
Suggest alternatives when a food is excluded or unavailable, and show progress toward nutritional goals.
Targets
Hit the balance your users actually need.
Macro targets and micronutrient priorities help plans stay useful in the real world — with flexible or stricter modes depending on the experience you want to offer.
- ▸Calories and macro targets aligned to each profile
- ▸Micronutrient focus for goals such as increasing iron intake
- ▸Variety across plans so regenerated schedules stay fresh
- Protein 30%
- Carbs 40%

Transparency
Recommendations your product can explain.
When preferences cannot all be satisfied, ONE can adapt in a controlled way — and surface what changed — while allergies and diet types stay non-negotiable.
Must-avoid rules
Allergies and dietary restrictions stay enforced so unsafe recommendations are not offered.
Flexible preferences
Dislikes and softer preferences can adapt when a perfect plan is not possible — with clear signals for your product UX.
Partner visibility
Operational views help your team understand how rules were applied during evaluation and support.
