Blueberry consumption linked to reduced cardiovascular risk

Research from the University of East Anglia indicates that consuming 150 grams of blueberries daily can reduce the risk of cardiovascular disease by 12% to 15%. The study, published in The American Journal of Clinical Nutrition, focused on 138 individuals aged 50 to 70 suffering from metabolic syndrome, characterized by high blood pressure, elevated blood sugar, abdominal fat, and low HDL cholesterol.

Dr. Peter Curtis, a co-leader of the study, noted that a daily intake of one cup (150 grams) resulted in sustained improvements in vascular function and arterial stiffness. Notably, the study found no significant benefits for participants consuming 75 grams or less per day, suggesting higher quantities are necessary for those at risk.

While blueberries are highly nutritious, the type of berry consumed may impact antioxidant levels. Wild blueberries (Vaccinium myrtillus) typically contain higher concentrations of phytonutrients compared to the larger, sweeter cultivated varieties (Vaccinium cyanococcus) often found in commercial markets, which are bred for yield and shelf life rather than nutrient density.
