The finding comes from Mette Svendsen of Oslo University Hospital
, presented at the American Heart Association’s
and colleagues randomly assigned 50 men and 68 women, with mild hypertension to eat either 3 kiwis a day or one apple a day for 8 weeks. No other dietary changes were made.
Ambulatory blood pressure monitoring was used to track the participants' blood pressure readings during daily activities.
The researchers suspect kiwi lowers blood pressure similar to dark green vegetables that contain lutein, a carotenoid and antioxidant linked to vascular and eye health.
Three kiwis a day is found in the study to naturally lower blood pressure 3.6mg/Hg systolic – the top number - compared to apples in the investigation.
The authors write, "Three kiwi a day improved 24-hour BP more than an apple a day. Incorporating kiwi intake as part of DASH or other diets for treatment of hypertension should be studied.
Eating a variety of colorful fruits and vegetables is the best way to balance nutrition for optimal health. Kiwis can be considered a worthwhile dietary addition to help keep blood pressure just a little bit lower.
