>>No sugar (beyond what's in OJ, milk, fruits, etc.)
So-called "free" sugar is the one that kills. Yes fruit has lots of sugar, but it's not free sugar.
FWIW, you can lose the fruit juice as well. Its raw constituent fruit also has roughage that you want. If you are looking for an amazing drink, try dihydrogen monoxide that has amazing health properties.
Caffeine can raise BP, but it's a cheap legal drug with other effects as well. I drink at least 6 shots per day which is more than the research du jour suggests but I'm yet to see definite evidence of harm.
Into the red medicine yet? ;-)
"... They ne'er cared for us
yet: suffer us to famish, and their store-houses
crammed with grain; make edicts for usury, to
support usurers; repeal daily any wholesome act
established against the rich, and provide more
piercing statutes daily, to chain up and restrain
the poor. If the wars eat us not up, they will; and
there's all the love they bear us."
-- Shakespeare: Coriolanus, Act 1, scene 1
