# How to Build Nutrition Labels with ChatGPT

ChatGPT creates nutrition labels that look professional and read clearly. Beyond the raw calculations, it formats output following FDA panel conventions, adds daily value percentages, and explains which nutrients make your recipe stand out. Great for food bloggers and meal prep services who need labels that are both accurate and presentation-ready.

## Setup

{"mcpServers":{"toolrouter":{"command":"npx","args":["-y","toolrouter-mcp"]}}}

## Steps

1. Configure ToolRouter in ChatGPT
2. Ask: "Create a nutrition label for this smoothie recipe: 1 banana, 200ml almond milk, 30g protein powder, 100g frozen berries"
3. ChatGPT looks up each ingredient and calculates totals
4. Request: "Format this as a nutrition facts panel"
5. Download the nutrition label data

## Example Prompt

```
Build a nutrition facts panel for my protein bar recipe: 100g oats, 60g peanut butter, 30g whey protein, 40g honey. Makes 6 bars. Show per-bar nutrition.
```

## Tips

- ChatGPT can format the output as a standard nutrition facts panel
- Ask for both per-serving and per-package totals
- Request daily value percentages for key nutrients
