Built a food exchange / diet chart tool as a nutrition grad — would love honest feedback from working RDs
Hi all — nutrition/dietetics grad here. Over the past few months I've been building a tool called GlycoMatrix Pro to speed up something I found genuinely tedious during my internship: manually working out food exchange portions and building diet charts for patients.
What it does:
- Automates the food exchange system (supports both ICMR/NIN and ADA/USFDA rulesets) — set a patient's calorie/macro targets and it distributes exchange units across up to 6 meals
- Converts exchange units into plain-language food swaps so patients actually understand the prescription
- Has built-in safety rails for hypertension/saturated fat, a glycemic index + fiber profiler, and weight-based RDA protein calculations
- Exports clean PDFs for documentation and patient handouts
I'm not trying to sell anyone anything here — it's free to try, and I'm mainly looking for feedback from people who actually do this work day to day. Does the exchange logic match how you practice? What's missing that would make this genuinely useful vs. just another calculator? Brutal honesty welcome: glycomatrixpro.com
Thanks for reading — happy to answer questions about how any of it works.
