Consumption of chokeberry berry modestly lowered blood pressure and reduced low-grade inflammation in patients with mildly elevated blood pressure.
Studies have shown that consumption of aronia berries may improve cardiovascular disease risk factor profiles.
In a recent 16-week single-blinded crossover trial, 38 participants received 300ml/d of cold-pressed chokeberry juice or 3g/d of oven-dried chokeberry powder or a placebo in random order for 8 weeks each.
As a result of the intervention, daytime ambulatory diastolic blood pressure was observed to decrease. The true awake ambulatory sytolic and diastolic blood pressures also tended to decrease.
Markers of inflammation like interleukin 10 and tumor necrosis factor alpha also tended to decrease.
It is hence suggested that inclussion of chokeberry products in daily diets of people with mildly elevated blood pressure has some beneficial effects on cardiovascular health.
