# How to Look Up Food Nutrition with ChatGPT

ChatGPT turns nutrition data into clear, everyday explanations you can actually use. Ask about any food and get not just the raw numbers but context on what they mean for your health goals, how they fit into recommended daily values, and creative suggestions for incorporating nutrient-rich foods into meals you will enjoy.

## Setup

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

## Steps

1. Configure ToolRouter in ChatGPT
2. Ask: "What is the nutritional information for brown rice?"
3. ChatGPT retrieves and presents the nutrition facts
4. Request: "Compare brown rice to quinoa nutritionally"
5. Use the comparison for your dietary decisions

## Example Prompt

```
Look up the nutrition facts for a large banana. Show me calories, sugar, potassium, and fiber content.
```

## Tips

- ChatGPT can explain what each nutrient does and why it matters
- Ask for nutrition data in the context of daily recommended values
- Request a comparison table for multiple foods at once
