Jerusalem artichoke

Also known as: sunchoke, topinambur extract

Jerusalem artichoke is a tuber rich in inulin, a soluble prebiotic fibre. Inulin feeds beneficial gut bacteria, especially bifidobacteria.

What it is used for

  • prebiotic effect and regular bowel movements – weak evidence for Jerusalem artichoke, moderate for inulin (EFSA claim for chicory inulin)
  • smaller blood sugar rise after meals – weak evidence

Forms and how they differ

tuber powder

contains inulin plus other components

extract capsules

low fibre dose, effect rather mild

syrup

a lower-glycaemic sweetener that still contains sugars

When to take it

With a meal; start with a small dose.

Pairs well with

Probiotics, plenty of water.

Do not combine / separate

With a sensitive gut do not combine several prebiotics at once.

Watch out for

With irritable bowel syndrome or a low-FODMAP diet it may worsen symptoms. During pregnancy or breastfeeding, with kidney or liver disease, or when taking medicines, consult your doctor.

Safety

The main side effects are wind and bloating. Do not exceed the label dose.

Practical tip

Fresh Jerusalem artichoke can be roasted like potatoes – the cheapest source of inulin.
