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

Serving size, prep, and portion notes for spinach
Spinach is genuinely nutritious and strongly anti-inflammatory, but it is also one of the highest-oxalate foods on the plate and grades high in histamine and salicylates. That combination is why a daily green smoothie or a big spinach salad can raise kidney-stone worries, itching or headaches even though the leaf itself is a nutrient powerhouse.
Watch for
Very high in oxalate, the single biggest reason spinach is limited on kidney-stone (calcium oxalate) diets / High in histamine and a moderate liberator, so it can drive itching, flushing or headaches in histamine intolerance / High in salicylates and a high-nickel food, extra triggers if you react to either / Often poorly tolerated in SIBO even though it is not especially high in the usual FODMAPs
