And most of the cocoa drinks in the experiments were specially made to have high levels of flavonoids—between 400 and 1000 milligrams—using cocoa that's processed differently than regular supermarket chocolate.

而且实验中使用的可可饮料大多数是特制成黄酮含量较高的，即含量在400到1000毫克之间，其选用的是特殊加工的可可，而不是一般超市的巧克力。

Some experimental studies, which are considered the best type of study for establishing cause and effect, have shown decreases in blood pressure when healthy adults were given specially developed, high-flavonoid cocoa drinks or chocolate.

实验研究被认为最能有效建立因果关系，部分此类研究表明，健康成年人在服用特殊加工后的高黄酮可可饮品或巧克力后，血压会下降。

For example, a 2014 study in Nature Neuroscience found that older adults did better on a memory task, and had increased blood flow to particular memory centres in the brain, if they'd had a high-flavonoid cocoa drink for three months.

比如 2014《自然神经科学》中的一项研究发现，如果老年人连续喝三个月高黄酮可可饮料，会在记忆力测试中表现得更好，并且脑部记忆中枢血液供给会增加。
