# How to Compare Nutritional Values with ChatGPT

ChatGPT presents food comparisons as clear, formatted tables and then explains what the differences actually mean for you. It goes beyond raw numbers to tell you why one option might be better for post-workout recovery, heart health, or weight management, helping you make informed choices without needing a nutrition degree.

## Setup

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

## Steps

1. Configure ToolRouter in ChatGPT
2. Ask: "Compare the nutrition of a banana versus an apple"
3. ChatGPT retrieves and presents the comparison
4. Request: "Which is better for a post-workout snack?"
5. Get a recommendation based on the nutritional data

## Example Prompt

```
Compare whole wheat bread vs sourdough vs white bread nutritionally. I want to know about calories, fiber, and glycemic impact.
```

## Tips

- ChatGPT can explain the health implications of nutritional differences
- Ask for context-specific recommendations based on the comparison
- Request the comparison as a formatted table for easy sharing
