我们来看一段相关的英文报道:
Proponents of healthy foods often urge us to pay attention to digestion. The latest is one of Beijing's hippest purveyors of tea, Martin Papp, whose Kombucha Challenge is "a six-day journey to gut health".
If you've never heard of it, kombucha is a fermented tea beverage, naturally carbonated and served cold.
"While maintaining your normal diet," he says, "drink a bottle of kombucha in the morning and one bottle in the evening for six consecutive days." That's enough to flush out the toxins and rejuvenate your gut bacteria.
文中的gut health就是“肠道健康”的意思，其中gut用作名词，意为“肠道，内脏”，如：Meat stays in the guts longer than vegetable matter.（肉类在肠中停留的时间比蔬菜长。）它还可以表示“（问题等）根本的”。这里说的恐怖茶（kombucha）虽然名字吓人，但其实就是调自一种茶菌发酵液，富含益生菌的茶饮料。
