Colorectal cancer kills forty five people in France every day. Epidemiological studies suggest that two cases out of three could be prevented and show that processed meat intake is a consistent risk factor. The aim of this study is to understand how meat promotes cancer, to find protective strategies, and to make compelling dietary recommendations.

Condition Intervention
Colorectal Cancer
Other: Ham
Other: Ham + calcium
Other: Ham + vitamin E

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Crossover Assignment

Official Title: Effect of Processed Meat on Colorectal Carcinogenesis. Study of Mechanisms. Choice of Preventive Strategies

Further study details as provided by Institut National de la Recherche Agronomique:

Primary Outcome Measures:
  • Urinary biomarker (DHN-MA:dihydroxynonene mercapturic acid), will be measured before and after every interventional period [ Time Frame: Twice a week, before and after every 4 days of interventional period ]

Secondary Outcome Measures:
  • Fecal biomarkers [ Time Frame: twice a week, before and after every 4 days of interventional period ]

Enrollment: 18
Study Start Date: October 2009
Study Completion Date: January 2010
Primary Completion Date: December 2009 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Placebo Comparator: Ham Other: Ham
Ham : 180 g per day during 4 days
Experimental: Ham + calcium Other: Ham + calcium
Ham : 160g/d during 4 days calcium : 1000mg/d during 4 days
Experimental: Ham + vitamin E Other: Ham + vitamin E
Ham : 160g/d during 4 days Vitamin E : 80 mg/d during 4 days

Detailed Description:
18 healthy volunteers will be randomized and will start the study. The study will last 4 weeks for each subject. The first week will be a week of adaptation (or run-in period) to the diet which they will have to follow for the duration of study. During this period, they will collect 2 samples of stools and urine. Then subjects will alternate 4 days of diet either with ham, or with ham and calcium, or with ham enriched with vitamin E. At least, 3 days will separate every period (wash-out) of nutritional intervention. Urines and stools will be collected last 3 days of every interventional period and also last day of every wash out period.
