# /nutrition — Post-Run Nutrition Analysis
Computes total and per-hour intake of water, carbohydrates, sodium, and caffeine from the athlete's reported fueling, then adds a summary note to the Intervals.icu event.
## Step 1: Read knowledge base
Read `knowledge/nutrition.md` to inform the analysis with fueling targets and expert recommendations.
## Step 2: Collect inputs
Ask the athlete (if not already provided) for:
- **What they consumed** — products, quantities, and how they were carried (e.g., "2 gels, 1 waffle, Tailwind in a flask")
- **Water volume** — total liters carried/consumed, and what was mixed into it (electrolyte tabs, drink mix, etc.)
Also identify the activity. If not specified, fetch the most recent activity from the last 3 days using the activities endpoint. You need the **elapsed time** (not moving time) to compute per-hour rates, since the athlete fuels during stops too.
## Step 3: Look up nutritional data
Use the reference table below for common products. For products not listed, use your best knowledge of the product's nutrition facts — state your assumptions and invite corrections.
