Study type not stated

  • Benefit

    Nutritional value of food5

    Jerusalem artichoke is rich in fiber and minerals, and adding it to food can lower the glycemic index.

Found in some samples or products

These come from where it was grown, how it was processed or cooked, or what it was made into. They are not about the ingredient itself, so the signal does not count them.

  • Heavy metals in tubers6

    Some Jerusalem artichoke tubers held cadmium and lead above EU limits, though everyday amounts eaten stayed low.

The signal at the top counts the findings in people and in animal and lab studies. A concern in studies of people outranks animal and lab studies, and “No concerns” needs at least one finding in people. When most findings in people point one way, the page leans that way (“Mostly”), and every finding is still shown. Findings whose study type is not stated are shown but not counted. This page is a reference, not medical advice. It describes what regulators and published research say. Talk to a doctor or dietitian about your own diet.
