Short answer

How can I compare nutritional data with my AI?

You can use the get_product tool to pull the 100g nutritional breakdown for any food item in the Open Food Facts database. Your AI then processes these values to highlight differences in sugar, protein, or fats between products. This allows for instant side-by-side comparisons without manual searching.

The results you get

Where your data lands

The AI handles the data retrieval and math, leaving you with the insights.

DATA

Standardized nutrition

The AI pulls the 100g breakdown for every product you name. You get consistent metrics to compare different brands or items.

ANALYSIS

Direct comparisons

Your agent identifies which product has more sodium, less sugar, or higher protein. It spots the differences you actually care about.

INSIGHT

Dietary alignment

The AI checks products against your specific dietary goals. It flags items that don't fit your requirements.

HUMAN

Final decision

The AI provides the data and the math, but you decide which product to actually buy or eat.

The workflow

What your AI does when you ask for a comparison.

The AI acts as a bridge between your chat interface and the Open Food Facts database.

  1. Fetch product data

    The AI looks up the specific food item you mentioned to find its nutritional profile.

  2. Normalize values

    The AI ensures all nutritional data is scaled to a 100g basis for an accurate comparison.

    get_product

  3. Calculate differences

    Your agent subtracts or compares the values of different products to find the outliers.

    get_product

  4. Present findings

    The AI outputs a clear summary or table showing how the products stack up against each other.
