Granaatappel: werkt als een ACE remmer

Granaatappelsap remt ACE activiteit en verlaagt de systolische bloeddruk (= de "bovendruk").

Atherosclerosis. 2001 Sep;158(1):195-8.
Pomegranate juice consumption inhibits serum angiotensin converting enzyme activity and reduces systolic blood pressure.

Consumption of pomegranate juice which is rich in tannins, possess anti-atherosclerotic properties which could be related to its potent anti-oxidative characteristics.

As some antioxidants were recently shown to reduce blood pressure, we studied the effect of pomegranate juice consumption (50 ml, 1.5mmol of total polyphenols per day, for 2 weeks) by hypertensive patients on their blood pressure and on serum angiotensin converting enzyme (ACE) activity.

(NOOT: de 50 ml is vermoedelijk (?) geconcentreerde granaatappelsap (dat komt overeen met ca 240 ml gewone sap)

A 36% decrement in serum ACE activity and a 5% reduction in systolic blood pressure were noted. Similar dose-dependent inhibitory effect (31%) of pomegranate juice on serum ACE activity was observed also in vitro.
As reduction in serum ACE activity, even with no decrement in blood pressure, was previously shown to attenuate atherosclerosis, pomegranate juice can offer a wide protection against cardiovascular diseases which could be related to its inhibitory effect on oxidative stress and on serum ACE activity.
