What research says

Studies in people

  • Benefit

    Blood sugar and cholesterol2

    In people, eating teff seeds for three months lowered blood sugar and cholesterol, but did not change body measurements.

  • Open question

    Anemia in pregnancy3

    Pregnant women who ate teff injera less often were more likely to be anemic.

Study type not stated

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.

  • Minerals in a grain5

    Red teff holds iron, manganese, copper and zinc, plus small amounts of lead and cadmium.

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.
