Hi n8n community! 
I wanted to share a health-focused workflow I recently built to automate my dietary management. I have just submitted this to the n8n Creator Hub as a template.
The Concept Instead of just generating random meal plans, this workflow acts as a “Dynamic AI Nutritionist.” It actually changes its behavior based on my physical health data from the past week.
How it works
-
Data Collection: It fetches my daily blood pressure logs from Google Sheets.
-
Analysis: It calculates the weekly average (Systolic/Diastolic).
-
AI Decision Making: An AI Agent analyzes the trend:
-
If BP is High
→ It searches specifically for “Low-sodium” or “Hypertension-friendly” recipes. -
If BP is Normal
→ It focuses on balanced, heart-healthy meals. -
If BP is Optimal
→ It focuses on nutritional variety.
-
-
Action: It uses Google Custom Search to find real recipes from the web and emails me a 5-day dinner plan via Gmail.
Localization Note Since I live in Japan, the current prompt and search logic are tuned to find Japanese recipes (searching local sites like Cookpad). However, the logic is universal! You can easily adapt it to search for Mediterranean diet recipes or Keto, depending on your health metrics.
I built this because I wanted to close the loop between “Tracking Health” and “Taking Action.” I’m currently waiting for the template review, but I’d love to hear your thoughts on using n8n for personal health management!
Thanks!
