What research says

Animal and lab studies only

  • Benefit

    Fat buildup in the body3

    In rats and human cells, adzuki bean extract lowered fat buildup and inflammation.

  • Benefit

    Blood pressure and antioxidants4

    In lab studies, peptides from Adzuki bean protein showed antioxidant and blood-pressure-related activity.

  • Benefit

    How fast starch is digested5

    Heating adzuki bean procyanidins with rice slowed starch digestion in lab tests, the authors found.

  • Benefit

    Blood sugar control6

    In animal and lab studies, black adzuki bean extract helped keep blood sugar steady and protected insulin-making cells.

  • Benefit

    Cholesterol absorption7

    In lab studies, adzuki bean compounds blocked cholesterol from being taken in by intestinal cells.

Study type not stated

  • Benefit

    Blood sugar after meals2

    Adzuki beans contain resistant starch, which does not put a big burden on blood sugar after eating.

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.
