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。
