科学美国人：Do Wine Over Those Brussels Sprouts
60秒科学节目（SSS）是科学美国人网站的一套广播栏目，英文名称：Scientific American - 60 Second Science,节目内容以科学报道为主，节目仅一分钟的时间，主要对当今的科学技术新发展作以简明、通俗的介绍，对于科学的发展如何影响人们的生活环境、健康状况及科学技术，提供了大量简明易懂的阐释。
Thanksgiving is, of course, really all about the side dishes. And alongside mashed potatoes and yams, Brussels sprouts are a common side on many Thanksgiving tables. Not that they're equally appreciated. But science is here to save turkey day, with a way to mitigate the sprouts' intense, slightly bitter flavor: take swigs of red wine as you eat 'em.
Like any human research study, or perhaps more importantly for one in which you'll be forcing people to eat Brussels sprouts, the project started off with approval from an ethics committee.
Researchers then served 28 volunteers slices of microwaved Brussels sprouts, and asked them to rate the intensity or bitterness of their flavor on a scale of 1 to 10. They then alternated their bites with red wine, gravy, and bottled water. And rated the flavor again.
Turns out, the subjects scored the sprouts as significantly less intense after a sip of wine: 3.5 out of 10, compared to 5.5. Maybe, the scientists write, because the astringency of wine interferes with saliva's ability to deliver bitter flavor molecules to the tastebuds.
The results are in the Journal of Texture Studies…a real publication. [Guy Carpenter et al, Wine astringency reduces flavour intensity of Brussels Sprouts]
Unfortunately for the kids at the table, gravy and water did not do the taste trick. But for adults who choose to use this Thanksgiving hack—please imbibe responsibly. Though I don't imagine you'll be eating that many Brussels sprouts.
