What research says

Studies in people

  • Benefit

    Blood sugar after eating3

    Adding yellow mustard bran to soup led to lower blood sugar levels in healthy men after the meal.

Animal and lab studies only

  • Concern

    Heart health7

    Some mustard oils and mustards contain erucic acid, which has been linked to heart problems in lab rats.

Study type not stated

  • Concern

    Food allergy risk4

    Mustard can trigger allergic reactions, and it is sometimes hidden in foods where you would not expect it.

  • Concern

    Seed proteins and allergy6

    Mustard seeds contain proteins that can trigger allergic reactions in some people, including ones scientists had not identified before.

How it’s made and used

  • Food texture and thickness5

    Yellow mustard mucilage thickens foods and forms gels, and scientists are exploring how it works with other ingredients.

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.
