Why Veggies Can Be Hard to Stomach

We've all heard that we must eat vegetables to stay healthy. The rainbow of produce available from a garden provides many of the nutrients that our bodies need to grow, repair, protect, and clean themselves. Then why do some people run for the hills every time they see a piece of broccoli? Recent research into our sense of taste may help cast some light on this.
The human mouth has more than 25 taste receptors, which register flavors in our food within the five basic tastes: sweetness, saltiness, sourness, bitterness, and umami. The taste receptor called TAS2R38 influences how we sense the bitter flavor. Genetic differences in TAS2R38 make a quarter of the population "super-tasters," which is not as appealing as it might sound. These people are particularly sensitive to bitterness in ordinary foods like spinach and cabbage and tend to eat far less vegetables as a result. This, in turn, may lead to heart or weight problems and other kinds of diseases.
Scientists are currently trying to come up with less bitter varieties of garden favorites. For now, super-tasters can try different cooking methods and spices to make those all-important vegetables easier to swallow.

 
不愛吃蔬菜跟基因有關?

我們都聽過必須要吃蔬菜才能維持身體健康。從菜園取得的五顏六色的農產品提供我們身體生長、修復、保護和清理所需的許多營養素。那為什麼有些人每次看到一塊青花菜就逃之夭夭呢?最近針對我們味覺的研究也許有助於釐清這一點。
人類的口腔有超過二十五種味覺接收器,能夠感受到我們食物中的五種基本味道:甜、鹹、酸、苦和鮮味。這個稱作TAS2R38的味覺接收器影響我們如何感覺苦味。TAS2R38的基因差異讓四分之一的人口成為「超級品嚐者」,這並不像聽起來那樣吸引人。這些人對菠菜和高麗菜等普通食物中的苦味特別敏感,結果往往蔬菜就吃得很少。進而就可能導致心臟或體重問題以及其他種類的疾病。
科學家現在正努力培育受歡迎的菜園蔬菜中比較不苦的品種。目前,超級品嚐者可以試不同的烹飪方法和香料來使那些非常重要的蔬菜更容易下嚥。

social distancing
社交距離

新冠肺炎疫情延燒全球,各國政府紛紛勸導民眾避免群聚及保持社交距離等措施來防疫。根據《韋伯字典》(Merriam-Webster's Collegiate Dictionary),此詞用來指在傳染病爆發期間,與其他人保持比平常更大的身體距離,或避免在公共場所與人或物體直接接觸以減少感染的傳播。現在來看看一些與疫情相關的字詞。

covidiot n. phr. 不配合防疫措施者;防疫豬隊友
(由COVID-19「新冠肺炎」加上idiot「白痴」結合而來)
contagious disease n. phr. 傳染性疾病
infection n. 感染;傳染病
precaution n. 預防;預防措施
hoarder n. 囤積者;儲藏者
confirmed case n. phr. 確診病例
imported case n. phr.  境外移入病例
community transmission n. phr. 社區感染
travel warning n. phr. 旅遊警示

A "covidiot" is someone who ignores social distancing rules or who selfishly hoards groceries for themselves.
「防疫豬隊友」是指漠視社交距離規定或自私地囤積日用品的人。
