Sensitivity notes
Why low fermentation food checker matters
SIBO (Small Intestinal Bacterial Overgrowth) diets focus on reducing fermentable foods that feed bacteria in the small intestine. Low-fermentation foods help manage symptoms like bloating, gas, and abdominal discomfort.
- Low-fermentation eating reduces food for overgrown bacteria
- Meal spacing (4-5 hours) allows the MMC to clear the gut
- Avoid grazing - structured meals are better
- Some find the elemental diet helpful under medical supervision
- Address underlying causes with your healthcare provider

What to know about fava beans
Fava beans carry a genuine safety warning that most foods do not: in people with G6PD deficiency, the most common enzyme deficiency worldwide, eating fava beans can trigger favism, an acute breakdown of red blood cells (hemolytic anemia). The beans contain vicine and convicine, compounds that create oxidative stress the G6PD-deficient body cannot buffer. On top of that, fava beans are one of the highest-FODMAP legumes, topping the scale for galacto-oligosaccharides (GOS), and are high in nickel.
Watch for
- Favism risk: in G6PD deficiency, the vicine and convicine in fava beans can trigger hemolytic anemia, with jaundice, dark or cola-coloured urine, fatigue and shortness of breath appearing 1 to 3 days after eating them.This is a medical emergency, not an intolerance
- Highest galacto-oligosaccharides (GOS) rating and top-of-scale total FODMAPs, so fava beans bloat a sensitive gut even in small portions
- High in nickel, relevant for systemic nickel allergy
- High in lectins, so they must be cooked thoroughly
