Dark chocolate it is then!

Remedies: Dark Chocolate Similar to Blood Pressure Drugs - New York Times:

    Four of the five studies on chocolate found
    reduced blood pressure after eating, but none of the tea studies showed
    significant benefit. The magnitude of the effect of eating three and a
    half ounces of dark chocolate a day was clinically significant,
    comparable to that of beta-blockers like atenolol, known by the brand
    name Tenormin, or propranolol, known as Inderal. The authors
    acknowledge that the studies were short and that results may not apply
    to habitual use.

Such news, of course, will not stop me from continue my tea-drinking
habit. It does he me and Laura justify our newly revitalized eating of
dark chocolate after dinner!
