Blueberries may boost heart and brain health, Harvard researcher says
Key Points:
- Blueberries are linked to potential benefits for heart and brain health, with studies suggesting they may protect against neurodegenerative diseases like Alzheimer's and Parkinson's.
- Research indicates that consuming about a cup of blueberries daily can improve blood vessel function and arterial stiffness, though evidence on preventing heart attacks or strokes is limited.
- Some studies show modest improvements in memory and cognitive flexibility, especially in older adults, but blueberries are not proven to prevent Alzheimer's disease.
- Experts recommend including blueberries as part of a balanced diet due to their antioxidant properties and fiber content, with both fresh and frozen options being practical choices.
- While blueberries are beneficial, no single food acts as a "magic bullet," so a varied diet remains essential for overall health.
