I love how this says chocolate drink.

我喜欢巧克力饮料的说法。

" Cocoa" here refers to a powdered chocolate, a form of chocolate that you use for cooking – or in this case, for making a chocolate drink usually combined with hot water or perhaps hot milk.

这里的“可可” 指的是巧克力粉，一种用于烹饪的巧克力——或者在这种情况下， 用于制作通常与热水或热牛奶混合的巧克力饮料。

For example, one 2015 study found that 100 adults who drank a high cocoa chocolate drink twice a day for one month had a drop in blood pressure of around 4 millimeters of mercury, which is a measure of pressure.

例如，一项2015年的研究发现100名成年人持续一个月，每天喝两次高可可含量的巧克力饮料，其血压下降了4毫米汞柱，毫米汞柱是血压的计量单位。
