Italian?scientists have found evidence that a daily dose of cocoa acts as a dietary supplement to?counteract?different types of cognitive decline.
意大利科學(xué)家發(fā)現(xiàn)證據(jù)表明，每天攝入一定量的可可，作為一種膳食補充劑，能對抗不同類型的認(rèn)知衰退。

Back in 2017, the team found that regularly eating cocoa was linked to improvements in working memory and visual information processing and cocoa could be particularly beneficial for certain people.
早在2017年，研究小組就發(fā)現(xiàn)，定期吃可可與改善工作記憶和視覺信息處理有關(guān)，而且對特定人群尤為有效。

Cocoa, is the dried and fermented bean from the cocoa tree used to make delicious chocolate treats. Cocoa has been studied extensively because, well, who wouldn't want that job.
可可，是從可可樹上提取的烘干和發(fā)酵后的可可豆，用于制作美味的巧克力點心。大家研究可可已經(jīng)研究得很透了，試問誰會不想研究它呢？

Over the years, it has been found that a range of naturally occurring chemicals in the cocoa bean have therapeutic effects.
這些年來，人們發(fā)現(xiàn)可可豆中的一系列天然化學(xué)物質(zhì)具有治療作用。

For example, polyphenols in dark chocolate were found to increase calmness and contentedness and flavanols were able to reverse age-related memory decline.
例如，人們發(fā)現(xiàn)黑巧克力中的多酚可以促進鎮(zhèn)靜和滿足感，黃烷醇能夠逆轉(zhuǎn)年齡導(dǎo)致的記憶衰退。

Before you start using this an excuse to scoff as much chocolate as humanly possible, just remember that chocolate also contains theobromine, a toxic chemical. Though to be at risk of poisoning yourself, you'd have to eat about 85 full sized chocolate bars.
在你以此為借口暴風(fēng)吸入人類極限的量的巧克力之前，記住巧克力還含有可可堿，它是一種有毒的化學(xué)物質(zhì)。雖然有風(fēng)險，但你得吃85根標(biāo)準(zhǔn)尺寸的巧克力棒才會中毒。

In the study, the team looked through the literature for effects of acute and chronic administration of cocoa flavanols on brain activity and, more specifically, what happens if you do this over a long period of time.?
在這項研究中，研究小組查閱了有關(guān)可可黃烷醇急性和慢性服用對大腦活動的影響的文獻，更具體地說，如果你長期服用可可黃烷醇會發(fā)生什么。

The scientists found that there was enough evidence to support the health claims attributed to cocoa, and, in particular, the flavanol compounds it contains.
科學(xué)家們發(fā)現(xiàn)，有足夠的證據(jù)支持主張可可健康的說法，尤其是可可中所含的黃烷醇化合物。

They noticed enhancements in working memory performance and improved visual information processing after consuming cocoa flavanols. The benefits varied depending on the demographic being tested.
?他們注意到，食用可可黃烷醇后，工作記憶的表現(xiàn)有所改善，視覺信息處理也有所改善。效果因受測人口而異。

For the elderly, it turns out that long term ingestion of cocoa flavanols improved attention, mental processing, working memory and verbal fluency and was most beneficial in those who had mild cognitive impairments or the beginnings of memory loss.?
對老年人來說，長期攝入可可黃烷醇可以提高注意力、心理處理能力、工作記憶和語言流利度，對那些有輕度認(rèn)知障礙或開始失憶的人最有好處。

今日詞匯

counteract /?ka?nt?r??kt/?

v.抵消；中和

?

這個詞由counter+act組成。counter，作為動詞時，意思是反擊、對著干。act，動詞，行動、舉止。

文中to counteract different types of cognitive decline，是指“抵消不同類型的認(rèn)知能力下降”。

所以，要腦子好還是要瘦，你只能選一個。
