5. Blueberries May Lower Blood PressureBlueberries appear to have significant benefits for people with high blood pressure, which is a major risk factor for heart disease.
In an eight-week study, obese people who had had a high risk of heart disease noted a 4–6% reduction in blood pressure after consuming 2 ounces (50 grams) of blueberries per day (18).
Other studies have observed similar effects — especially for postmenopausal women (19, 20).
