What research says

Studies in people

  • Benefit

    Weight and blood sugar2

    In overweight adults, eating barley cereal daily led to lower body weight and better blood sugar than corn cereal.

Study type not stated

  • Open question

    Allergy risk in cereals3

    Scientists do not yet know whether barley starch could trigger reactions in people allergic to cereals.

  • Concern

    Gluten in gluten-free beer4

    Barley beers labelled gluten-free may still contain gluten pieces that could affect people with coeliac disease.

  • Concern

    Gluten reaction in celiac disease5

    Barley hordeins are gluten proteins that trigger reactions in people with celiac disease, so scientists are breeding barley with less hordein.

  • Open question

    Antioxidants in bread6

    Pita made with whole grain or pearled barley flour had more antioxidants than standard pita, and most also had more vitamin E.

  • Open question

    Folate in food7

    Barley flour made into pasta and biscuits had more folate than regular shop versions.

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 two findings in people. 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.
