# How to Compare Nutritional Values with Claude

Claude runs multi-food comparisons as a fluid research session. Pull up three milks side by side, ask which wins on protein, pivot to calcium content, then add a fourth option you just thought of. The conversation builds on itself so your comparison gets more nuanced with each question rather than starting from scratch.

## Setup

claude mcp add toolrouter -- npx -y toolrouter-mcp

## Steps

1. Connect ToolRouter: claude mcp add toolrouter -- npx -y toolrouter-mcp
2. Ask Claude: "Compare the nutrition of almond milk vs oat milk vs whole milk using nutrition-data"
3. Claude retrieves nutrition data for each and presents a comparison
4. Ask: "Which is the best choice for someone trying to increase protein intake?"
5. Use the comparison to make an informed choice

## Example Prompt

```
Compare brown rice, white rice, and quinoa nutritionally. Show calories, protein, fiber, and key vitamins per cooked cup. Which is the most nutritious overall?
```

## Tips

- Compare per 100g for standardized comparisons
- Ask Claude to highlight the biggest nutritional differences
- Request a recommendation based on your specific dietary goals
