Summary

Colorectal Cancer is, in non-smokers for both sex, first cause of cancers mortality in Western country. The main risk factors associated with colorectal cancer depend of lifestyle, and processed meat and red meat could be involved in carcinogenesis by cytotoxic and genotoxic compound linked to lipid peroxidation and nitrosation. The aim of this study is to study the impact of the daily consumption of beef, processed or not, on lipid peroxidation induced heme iron ; and to study the impact of the daily consumption of ham, processed or not, on the nitrosilation induced heme iron.

Detailed description

24 healthy volunteers will be randomized and will start the study. The study will last 12 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 3 samples of stools and urine. Then subjects will alternate 4 days of diet either with ham, or with ham and pomegranate extract, or with ham enriched with vitamin E or sirloin steak, marinated sirloin steak or marinated cooked sirloin steak. 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.
