- May Improve Brain Health: Studies suggest that blueberries may improve memory, cognitive function, and protect against age-related cognitive decline. The antioxidants in blueberries may help reduce oxidative stress and inflammation in the brain.
- May Support Heart Health: Blueberries may help lower blood pressure, reduce LDL (“bad”) cholesterol oxidation, and improve blood vessel function, all of which are beneficial for heart health.
- May Help Manage Blood Sugar: Blueberries have a relatively low glycemic index (GI) and contain fiber, which can help regulate blood sugar levels.
- May Reduce the Risk of Certain Cancers: Some studies suggest that the antioxidants in blueberries may help protect against certain cancers, but more research is needed.
- May Improve Urinary Tract Health: Like cranberries, blueberries contain compounds that may help prevent urinary tract infections (UTIs).
