If you have mild high blood pressure or also called pre-hypertension, then you should consider regularly eat raisins. A handful of raisins three times daily seem to significantly lower blood pressure in these people. The improvement was even greater when compared to eating other snacks.
Researchers from the Louisville Metabolic and Atherosclerosis Research Center (L-MARC) presented the results of their research at the annual meeting of the American College of Cardiology. The research was made possible by the California Raisin Marketing Board.
The Research
Even though raisins are often recommended as a snack for people suffering from high blood pressure, according to the researchers for the first time there is scientific proof on the antihypertensive properties of raisins compared to other snacks. “We could find little objective research in medical literature until this study was performed,” said lead researcher Harold Bays.
Together with his colleagues they studied the effect of bays raisins and other snacks in blood pressure of 46 adults with pre-hypertension. The control snack such as crackers and chocolate biscuits did not contain raisins, vegetables or fruit, but had the same amount of calories as a serving of raisins. The participants of this study snacked on their foods three times daily for 12 weeks.
Lowering the Blood Pressure
The raisins reduced both systolic and diastolic blood pressure significantly after 4, 8 and 12 weeks during the study. The control snacks did not have this effect. Dr. Bays said “If you can choose between raisins or another snack such as crackers, it seems wise for your blood pressure to go for the raisins.”
The researchers have not demonstrated why the raisins lower blood pressure. “Raisins are rich in potassium, a mineral which we know have properties to lower blood pressure,” explains Dr. Bays “In addition, and they are a source of antioxidants and fiber.”
Yet there are also other foods rich in potassium, such as potatoes, coffee, fruit and vegetables. If you are curious about these effects of raisins, simply consult your nutritionist.
