But in a subset analysis of 1568 participants later asked to recall their
chocolate intake over a 24-hour period, 57% ate
milk chocolate, 24% dark
chocolate, and 2% white chocolate.
Participants were divided into quartiles according to their level of chocolate consumption. Those in the top quartile, eating around 7.5 g of chocolate a day, had blood pressure that was about 1 mm Hg (systolic) and 0.9 mm Hg (diastolic) lower than those in the bottom quartile.
