# How to Track Micronutrient Content with Claude

Claude turns micronutrient tracking into a guided exploration. Ask about iron in spinach, then naturally follow up with other iron-rich foods, compare absorption rates between plant and animal sources, and build a comprehensive list of foods that cover your gaps. The conversation deepens your understanding with each question.

## Setup

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

## Steps

1. Connect ToolRouter: claude mcp add toolrouter -- npx -y toolrouter-mcp
2. Ask Claude: "What is the iron content of spinach, lentils, and red meat? Use nutrition-data"
3. Claude retrieves the iron content for each food
4. Ask: "Which foods should I eat to get enough iron on a vegetarian diet?"
5. Build a diet plan that meets your micronutrient targets

## Example Prompt

```
Look up the vitamin D, calcium, and iron content of salmon, kale, and fortified cereal. I want to know which foods cover these micronutrients best.
```

## Tips

- Ask Claude to identify micronutrient gaps in your typical daily meals
- Request foods ranked by a specific micronutrient per calorie
- Compare plant-based and animal-based sources for each micronutrient
