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 root beer
Root beer is a sweet, usually caffeine-free soda flavoured with wintergreen and sassafras, and that mix gives it a different trigger profile from cola. It is caffeine-free, but it is loaded with sugar or high-fructose corn syrup, which makes it high in excess fructose and high FODMAP, a common cause of gas and bloating. The wintergreen and sassafras flavouring also brings a moderate dose of salicylates that cola does not.
Watch for
- High in excess fructose (E) and high FODMAP (E) from the sugar or high-fructose corn syrup, a frequent trigger for bloating, gas and loose stools
- Moderate salicylates (C) from wintergreen (methyl salicylate) and sassafras flavouring, worth noting if you react to aspirin or salicylate-rich foods
- Caffeine-free, unlike cola, so it will not keep you awake, but the sugar load is just as high
