IBS Food Diary App — Reveal Your Trigger Foods
Living with IBS often means years of wondering which meal triggered the flare-up. Nutae was built to help you observe those patterns — without the guessing.
IBS: no easy diagnosis, no obvious trigger
Irritable bowel syndrome (IBS) affects roughly 10–15 % of adults worldwide. It's a chronic functional gut disorder with abdominal pain, bloating, and irregular transit (diarrhea-predominant IBS-D, constipation-predominant IBS-C, or mixed IBS-M).
The classic frustration: no scan or blood test sees IBS. Gastroenterologists diagnose it after ruling out other conditions — a process that often takes years (12 years on average for some patients, per UK forum verbatim).
Once diagnosed, the next frustration begins: identifying your own food triggers. Paper journals get illegible fast. Mainstream apps lack the statistical method to distinguish a real correlation from a coincidence.
How Nutae helps you observe your IBS flare-ups
Nutae turns your food diary and symptom logs into a rigorous statistical analysis. No black-box AI. Correlations are computed on your device using established tests: Fisher exact for categorical variables, Mann-Whitney U for ordinals, Benjamini-Hochberg FDR correction to handle multiple comparisons.
In practice: you log meals in 30 seconds (photo or text), symptoms in one tap. After 7 days of observation, the first signals emerge. By day 14, your real trigger foods stand out clearly — distinct from coincidences.
- Real probability, not a feeling
- Statistical coincidences are filtered out (BH-FDR correction)
- You see if a food is likely, certain, or to be confirmed
- Your data stays on your iPhone or Android — GDPR Article 9
Beyond the diary: a report your gastroenterologist will read
Premium Nutae generates a doctor-ready PDF your gastroenterologist understands in 30 seconds: probable triggers with their evidence level, symptom frequency, average intensity. Walk into your appointment with measured observations, not 'I think maybe it's the lactose.'
Combined with Nutae's guided FODMAP elimination plan, this report supports the conversation with your doctor and helps orient further testing (lactose intolerance, SIBO, etc.) with a solid baseline.
What Nutae is not
Nutae is not a medical device. It does not diagnose, treat, cure, or prevent IBS or any other condition. The correlations shown are observational aids — share them with your doctor or gastroenterologist.
Before starting any extended elimination protocol, talk to a healthcare professional. A poorly run diet can deplete your gut microbiome.
FAQ
How long until I see my first IBS triggers?
First signals appear after 7 days of observation. Your real trigger foods emerge clearly from day 14 of regular use, once coincidences are statistically filtered out.
Does Nutae work for IBS-D, IBS-C, and IBS-M?
Yes. Nutae's symptom logging covers transit changes, bloating, abdominal pain, and gas — the statistical analysis works across all IBS subtypes.
Do I need an IBS diagnosis to start using Nutae?
No. Nutae is useful from the first recurring digestive symptoms — it can serve as observation support to prepare your first gastroenterology appointment.
Does it work for Crohn's or ulcerative colitis?
Nutae is designed for IBS and recurrent digestive discomfort. For IBD (Crohn's, ulcerative colitis), it can complement but never replace specialist medical follow-up.
