I found I had high-normal blood pressure last year and have tried to cut down on alcohol consumption, as well as salt in my diet. I actually do eat a pretty healthy, mainly vegetarian diet with a lot of Omega3 rich fish. But it doesn t seem to have had any affect on my blood pressure at all. Obviously, being high-normal I don t need to worry too much, but I d like to lower it a little. One constant seems to be Red Bull, which I drink almost every day. Is this to blame? The reason why I say Red Bull and not strictly caffeine is because of the concoction of other chemicals and taurine it also contains. RB has the same amount of caffeine as a mug of coffee or two mugs of tea.
