科学研究：抹茶粉能减肥？假的

When you google "weight loss" the challenge to sort fact from fiction begins.

当你开始谷歌“减肥”时，你就面临着从谎话中辨认真相的挑战。

Matcha green tea powder claims to speed up weight loss, but let's see what the evidence says.

据说，绿茶抹茶粉可以促进减肥，不过还是让我们看看其根据。

Matcha is a green tea made from leaves of the Camellia sinensis, or tea plant, but it's processed into a green powder and can be mixed into liquids or food.

抹茶是用茶树叶子制成的一种绿茶，但它被加工成了一种绿色粉末，可以加入液体或食物中。

Before the leaves are harvested, the tea plant is put in the shade for a few weeks, which increases the content of theanine and caffeine.

在收割茶叶之前，茶树要在阴凉处放置几周以增加茶氨酸和咖啡因的含量。

No studies have tested the effect of matcha on weight loss. A review of six studies using green tea preparations for weight loss over 12 weeks found a difference based on country. In studies conducted outside of Japan, people consuming green tea did not lose more weight than controls.

没有研究测试过抹茶的减肥效果。人们使用绿茶制剂进行了6次为期12周的减肥研究。回顾了这六次研究的结果后发现，各国的情况有所不同。除了日本，在其他国家进行的研究中，饮用绿茶的人并没有比对照组减掉更多体重。

In the eight studies conducted within Japan, the mean weight loss ranged from 200 grams to 3.5 kilos in favour of green tea preparations.

在日本进行的八项研究中，绿茶制剂的平均减肥效果从200克到3.5公斤不等。

Verdict: Fiction! There are currently no studies testing whether matcha tea accelerates weight loss.

结论：都是假的！目前还没有研究测试抹茶是否能促进减肥。
