Garlic
Garlic contains high levels of fructans — fermentable carbohydrates the gut cannot absorb. Even a small amount can trigger bloating, cramping, and IBS symptoms. Avoid during the elimination phase.
Why is garlic high FODMAP?
Garlic is rich in fructans, a type of oligosaccharide (the "O" in FODMAP). Humans lack the enzymes to break down fructans, so they travel undigested to the large intestine where gut bacteria ferment them — producing gas and drawing in water.
According to Monash University, garlic becomes high FODMAP at just 1 clove (3g). Garlic powder is also high FODMAP — dehydration concentrates the fructans further.
The good news: fructans are water-soluble but not oil-soluble. Garlic-infused oil is safe because the flavour transfers to the oil while the fructans stay in the garlic solids.
Tips & alternatives
- 🫙Garlic-infused oilThe best substitute. All the flavour, zero fructans. Fry whole cloves in oil and remove before eating — or buy certified low-FODMAP garlic oil.
- 🌿Garlic chivesMild garlic flavour, low FODMAP in standard servings. Works well in stir-fries and as a garnish.
- 🌱Asafoetida (hing) powderAn Indian spice with a similar savoury depth. A small pinch goes a long way. Low FODMAP.
