Short answer: A SIBO diet app can help you organise meals and log symptoms, but it cannot diagnose or treat bacterial overgrowth. Diagnosis and antibiotic decisions belong to your doctor. Choose a tool for one clear job: food checks, symptom logging or a weekly meal plan. Nutrition.io offers a free assessment and an optional structured report.
Free tool: AIP, low-FODMAP and Hashimoto's food checker — check any food against AIP, low-FODMAP and Hashimoto's side by side.
Medical disclaimer: SIBO is diagnosed and treated by clinicians, usually with breath testing and antibiotics. Diet is supportive. See a doctor promptly for unintended weight loss, persistent vomiting, blood in stool, fever, or signs of malnutrition such as numbness or severe fatigue.
| Your actual need | Option to consider | What to check before choosing |
|---|---|---|
| Check single foods for fermentable carbohydrates | Monash University FODMAP app | Lab-tested, serving-based ratings; SIBO is not its stated focus |
| Log meals, bloating and bowel habits | A general food and symptom logger | Custom symptom fields and data export to share with your doctor |
| Get a week of meals that fits your preferences | Nutrition.io assessment and optional report | Free score; $9.99 USD one-time report; not a SIBO protocol |
| Confirm SIBO or choose treatment | Your gastroenterologist | Breath testing, antibiotics and underlying causes |

The American College of Gastroenterology guideline recommends breath testing for diagnosis and antibiotics as treatment, and does not endorse a single SIBO diet (Pimentel et al., 2020). The North American breath-testing consensus explains how results should be interpreted (Rezaie et al., 2017). Diets such as low FODMAP or low fermentation are mainly used to reduce symptoms, and their evidence comes largely from IBS research (Black et al., 2022).
So the honest promise of any app is symptom management and organisation, not "killing bacteria" or "curing SIBO". Be cautious with any product that sells a diet as a replacement for testing or treatment. Our SIBO diet guide has the full food list and 7-day plan, and the low fermentation diet explains that approach and its limits.
Words like "eradicate" or "heal SIBO" are a red flag. A legitimate tool says it helps you plan and track.
Dates, meals, bloating, pain and bowel changes are useful at follow-up. Make sure you can export or copy them.
Prolonged restriction can reduce nutrient intake. Choose a tool that lets you reintroduce foods rather than locking you into the narrowest list. Nutrition.io's report builds a seven-day menu from your dietary pattern, cooking time and foods you avoid; check ingredients yourself, as it is not certified for any specific SIBO protocol.
Nutrition.io's score is free. The optional report is $9.99 USD once, with tax and the final total shown before checkout. The mobile app is separate.
You can copy your complete purchased plan into an AI assistant you trust for daily check-ins. See the AI meal tracker guide first.
If IBS without confirmed SIBO is more likely, compare low FODMAP apps. If methane-dominant results are your concern, read methane SIBO foods to avoid. The gut health hub links every gut guide.
Some apps market SIBO food lists, but no app replaces breath testing and clinical treatment. Most people combine a food reference, a symptom log and a meal plan.
Ask your prescribing doctor. Guidelines do not mandate a specific diet during treatment, and some clinicians prefer a normal diet while antibiotics are taken.
No. Symptoms overlap with IBS, coeliac disease and other conditions, so testing is needed.
