3) Coconut water. Rich in potassium, electrolytes, and other important nutrients, coconut water has been shown to help significantly lower blood pressure levels in most of the people that drink it. A recent study published in the West Indian Medical Journal found that drinking coconut water helped 71 percent of participants achieve a significant reduction in systolic pressure, and 29 percent of participants achieve a significant reduction in diastolic pressure. The results were even more amplified when participants drank both coconut water and mauby, a tropical drink made from buckthorn tree bark.
Some research on watermelon extract and high blood pressure suggests the amino acid citrulline found in the fruit may help manage high blood pressure. One study found those who took watermelon extract showed reduced blood pressure specifically in the ankles and arm arteries. Other studies on mice also show watermelon’s positive effect. Although more research is needed to determine the specifics, eating fruit like watermelon isn’t going to hurt.
