Look Up Food Nutrition
Search for any food and get detailed nutritional information including calories, protein, fat, and carbohydrates.
Track Micronutrient Content
Research vitamin and mineral content in foods to ensure adequate micronutrient intake across your diet.
Quick answer: Use the Nutrition Data tool through ToolRouter to track micronutrient content directly from Claude, ChatGPT, Microsoft Copilot, and OpenClaw — connect once, then drive it with plain-language prompts. No code required.
ToolMost people track calories and macros but ignore micronutrients -- the vitamins and minerals that are equally important for health. Iron deficiency causes fatigue. Low vitamin D weakens bones. Insufficient B12 affects brain function. Yet finding which foods are rich in specific micronutrients requires digging through scattered databases and conflicting information.
The get_nutrition skill returns the full micronutrient profile of any food, including vitamins A, B, C, D, E, K, iron, calcium, potassium, magnesium, zinc, and more. Search for foods rich in the micronutrients you need, compare options, and build a diet that covers all your nutritional bases -- not just the macro ones.
This is valuable for people with identified deficiencies looking for food-based solutions, vegetarians and vegans ensuring they get nutrients typically found in animal products, pregnant women tracking folate and iron, and health professionals building comprehensive nutrition plans for clients.
How to track micronutrient content with Claude, ChatGPT, Microsoft Copilot, and OpenClaw
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.

How to track micronutrient content with Claude
Once connected (see setup above), use the Nutrition Data tool:
- Ask Claude: "What is the iron content of spinach, lentils, and red meat? Use nutrition-data"
- Claude retrieves the iron content for each food
- Ask: "Which foods should I eat to get enough iron on a vegetarian diet?"
- Build a diet plan that meets your micronutrient targets
Example prompt for Claude
Try this with Claude using the Nutrition Data tool
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 for Claude
- 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
ChatGPT pairs micronutrient data with clear health explanations. It does not just tell you that kale has 120% of your daily vitamin K -- it explains what vitamin K does, why it matters, and which other foods complement it. This makes micronutrient tracking accessible even if you have no nutrition background, turning data into practical dietary guidance.

How to track micronutrient content with ChatGPT
Once connected (see setup above), use the Nutrition Data tool:
- Ask: "What vitamins and minerals are in a cup of broccoli?"
- ChatGPT returns the full micronutrient profile
- Request: "Which common foods are highest in vitamin C?"
- Use the information to diversify your micronutrient sources
Example prompt for ChatGPT
Try this with ChatGPT using the Nutrition Data tool
I think I might be low on magnesium. Look up the magnesium content of almonds, dark chocolate, avocado, and banana. How much of each would I need daily?
Tips for ChatGPT
- ChatGPT can explain the health role of each micronutrient
- Ask for daily recommended values to put the numbers in context
- Request a weekly meal plan that covers all major micronutrient needs
Copilot pulls micronutrient data into your editor as code-ready structures. Generate JSON mappings of vitamin-rich foods, build nutrient-deficiency recommendation engines from real data, and populate health app databases with accurate mineral content. The structured output slots directly into application logic without manual parsing.

How to track micronutrient content with Copilot
Once connected (see setup above), use the Nutrition Data tool:
- In Copilot Chat: "Get the vitamin and mineral content of spinach using nutrition-data"
- Copilot returns the micronutrient breakdown
- Ask: "Generate a JSON mapping of top iron-rich foods with their iron content per 100g"
- Integrate the data into your health application
Example prompt for Copilot
Try this with Copilot using the Nutrition Data tool
Look up vitamin C content for 10 common fruits and return as JSON sorted by vitamin C per 100g. For my nutrition tracking app.
Tips for Copilot
- Build micronutrient tracking features using real food data
- Create nutrient-deficiency recommendation engines from the data
- Generate educational content about food micronutrient density programmatically
OpenClaw extracts micronutrient profiles in bulk, processing entire food lists and returning structured vitamin and mineral data ready for analysis. Use it to build comprehensive nutrient databases, generate ranked lists of foods by specific micronutrient density, or audit dietary plans against recommended daily values at scale.
