Eating blueberries every day improves heart health

A six-month study involving 138 overweight and obese older adults (50-75) with Metabolic Syndrome found that eating one cup of blueberries per day resulted in sustained improvements in vascular function and arterial stiffness, reducing the risk of cardiovascular disease by 12-15%. There was no benefit of a smaller 75 gram (half cup) daily intake of blueberries.
