I find this study to be highly questionnable and honnestly to the point of being unethical. Mainly, the diet protocol really made me unhappy:
''Participants randomly assigned to the control diet (referred to hereafter as the high-meat group) were instructed to follow their usual diet with the additional criteria: (1) to consume a minimum of 2 servings of red meat or processed meat each week.''
Instructing IBD patient (who are known to have increased risk of colon cancer) to consume a well known food that is associated with higher risks for colonic cancer is non sense and counter-productive to me.
previous thread I posted on the subject:
The World Health Organization and The International Agency for Research on Cancer (IARC) have evaluated the carcinogenicity of processed meats and red meat. Warnings mainly for colorectal cancer: http://www.iarc.fr/en/media-centre/pr/2015/pdfs/pr240_E.pdf .

Although the relation between red and processed meat intake and colorectal cancer has been reported in several epidemiologic studies, very few investigated the potential mechanisms. This study examined multiple potential mechanisms in a large U.S. prospective cohort with a detailed questionnaire...

Considering our high risk for colonic cancer, there is enough solid evidence out there to deter us from consuming processed meats. Doctors should never encourage or instruct high risk colonic cancer population such as us IBD patients to eat it, even if its only for 6 month study. Thats really not right
If this study with this diet protocol had been in my hospital I would have objected very strongly to it.
