because of their deep blue-purple color.
That color comes largely from natural plant pigments called anthocyanins.
Why Are Anthocyanins Interesting?
Anthocyanins are antioxidant compounds found in many deeply colored fruits and vegetables.
They are responsible for the red, purple, and blue colors seen in foods such as:
- Bilberries
- Blueberries
- Blackberries
- Cherries
- Purple grapes
- Blackcurrants
Researchers have studied anthocyanins because of their potential role in supporting normal cellular function and cardiovascular health.
However, eating an anthocyanin-rich fruit should be viewed as part of an overall healthy diet—not as a treatment for a medical condition.
How Could Bilberries Support Eye Health?
Bilberries have a long history of being associated with vision and eye health.
The interest partly comes from their anthocyanin content and antioxidant properties.
Oxidative stress can contribute to damage at the cellular level, and antioxidants obtained from a varied diet help protect cells from oxidative processes.
