Dark chocolate seems to lower blood pressure, but it requires an amount that is less than two Hershey's Kisses to do it, a small study suggests.
The new research from Germany adds to mounting evidence linking dark chocolate with health benefits, but it's the first to suggest that just a tiny amount may suffice.
Volunteers for the study were randomly assigned to eat just over 6 grams пїЅ" equal to about 1 1/2 Hershey's Kisses - of either dark chocolate or white chocolate daily for almost five months.
The people eating the dark chocolate experienced a drop in blood pressure without any weight gain, doctors found, compared with no change in blood pressure readings in the white chocolate group.
The results echo other small studies of cocoa-containing foods. Cocoa contains flavanols, plant-based compounds that also are credited with giving red wine its heart-healthy benefits. White chocolate does not contain cocoa.
University of Cologne researcher Dr. Dirk Taubert said the blood pressure reductions with dark chocolate were small but still substantial enough to potentially reduce cardiovascular disease risks.
