control arm is standard care-現有生活，包括standard American diet

可以參考一下這兩個大的試驗：

--Mediterranean Diet Reduces Atherosclerosis Progression in Coronary Heart Disease: An Analysis of the CORDIOPREV Randomized Controlled Trial

 

--Reduction in the Incidence of Type 2 Diabetes with Lifestyle Intervention or Metformin

也看一下新的:american national cancer care plan (https://www.hhs.gov/about/news/2023/04/03/hhs-releases-national-cancer-plan.html)

雖然不容易，但是這樣的試驗也不少了。記住素食不是WFPD，薯條也是素食，素食不一定健康。我設計的試驗和Ornish的試驗裏研究者隻需要提供3個月的套餐。
