Strawberry

Studies in people

• Benefit

  Blood vessel health in teens²

  In overweight teen boys, strawberry powder raised blood nitrate levels and improved blood vessel function in some.

Animal and lab studies only

• Benefit

  Blood vessel inflammation⁷

  In animal studies, strawberries helped blood vessel inflammation, but antibiotics blocked this, so gut bacteria seem needed.

Study type not stated

• Concern

  Allergy and kidney stones³

  Strawberries contain oxalates and compounds that can cause allergies.

• Benefit

  Oxidative stress and disease⁴

  Strawberry is rich in vitamin C and polyphenols, which studies suggest may help lower oxidative stress in the body.

• Concern

  Pesticide residues in fruit⁵

  About a quarter of strawberry samples tested in Beijing contained pesticide residues, and a few were above China's limit.

• Open question

  Antioxidants from fruit⁶

  Strawberry seeds make up a small part of the fruit but hold most of its antioxidants.

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.
