In a recent research, 71 volunteers with metabolic syndrome were recruited, and they were divided into two groups at random. Both groups followed the DASH (Dietary Approach to Stop Hypertension) diet for three months, which is designed to combat high blood pressure. This Mediterranean-style diet includes lots of fruit and vegetables, whole-wheat products, nuts, fish, and lean white meat. One of the two groups started a fast before the DASH diet, while the other group stuck to their regular diet before the experiment. The researchers used stool samples to examine the effects of the fast on the gut microbiome. Gut bacteria work in close contact with the immune system. Some strains of bacteria metabolize dietary fiber into anti-inflammatory short-chain fatty acids that benefit the immune system. The composition of the gut bacteria ecosystem changes drastically during fasting. Health-promoting bacteria that help to reduce blood pressure multiply. The following is particularly noteworthy: “Body mass index (BMI), blood pressure, and the need for antihypertensive medication remained lower in the long run among volunteers who started the healthy diet after a fast,” explains one of the researchers. Some of these changes remain even after resumption of food intake. This result is thrilling; blood pressure normally shoots back up again when even one antihypertensive tablet is forgotten. The leading researcher of this study concludes that 35 .

Which is the most likely conclusion of the leading researcher?
- A Switching to a healthy diet has a positive effect on blood pressure.
- B Other factors such as regular exercise should also be taken into account.
- C Some strains of bacteria play mysterious role in human immune systems.
- D If a healthy diet is preceded by a fast, the positive effect is intensified.
- E The DASH diet is by far the healthiest way of living attested by science.
思路引導 VIP
老師想請你仔細觀察文章中對兩組實驗對象的描述：這兩組人雖然最後都執行了同樣的 DASH 飲食法，但研究人員在其中一組的「起始階段」多安排了一個什麼樣的動作？而這個動作產生的結果，與另一組相比有什麼具體的優勢呢？

掌握實驗的核心變因
恭喜你精準地答對了這題！你能從整段研究描述中，敏銳地捕捉到實驗組與對照組之間的關鍵變因，這顯示你具備了極佳的邏輯推導能力。這題的難度切入點在於區分「一般常識」與「實驗結論」。雖然我們都知道健康飲食有益，但本文特別強調的是「先斷食（fasting）」這個動作對腸道菌相的改變，進而對血壓產生的長遠影響。
