Recent Research on the Health Benefits of Blueberries and Their Anthocyanins - PMC

The Nugget

Blueberries and their anthocyanins have significant health benefits, such as reducing the risk of cardiovascular disease, type 2 diabetes, and improving weight management and neuroprotection.
These benefits stem from their anti-inflammatory, antioxidant actions and beneficial effects on vascular and glucoregulatory function.

Key insights

Epidemiological studies link regular, moderate blueberry and anthocyanin intake with reduced risk of cardiovascular diseases and diabetes, as well as improved weight management.
Blueberries might improve neurocognitive function and offer neuroprotection, potentially delaying cognitive decline in older adults.

The health-enhancing effects of blueberries are attributed to their high content of anthocyanins, which have strong antioxidant and anti-inflammatory properties.
Blueberries can influence vascular health, improving endothelial function and reducing arterial stiffness, possibly through effects on nitric oxide metabolism and endothelium composition.
They may also interact beneficially with gut microbiota, influencing gastrointestinal health and contributing to their systemic health benefits.

Clinical and observational studies have shown blueberries' role in reducing biomarkers of cardiovascular risk, improving lipid profiles, and enhancing insulin sensitivity.
They help mitigate hypertension and improve arterial health, potentially through their effects on arterial stiffness and systolic blood pressure.

Blueberry intake has been associated with enhanced cognitive function and neuroprotection in both human and animal studies, including protection against age-induced cognitive decline and enhancing brain activity.

Studies suggest that blueberry and anthocyanin intake may support vision health, including reducing the risk and slowing the progression of conditions such as macular degeneration and glaucoma.

Blueberry intake, closely associated with higher flavonoid intake, is linked to less weight gain, supporting weight management and reducing obesity-related health risks.
