<br /></p><p>The protein consumption in countries like USA and France
is largely above the recommended dietary intake and can represent
more than 4 times this value in slimming hyperproteic (HP) diet. This
results in increased transfer of undigested protein from
the small to the large intestine. We have shown in the rat model that HP
diet ingestion results in marked changes of the luminal
environment of the colonic epithelial cells with modifications of the
microbiota composition and its metabolic capacity. HP animals
had increased colonic water content and amino acid-derived bacterial
metabolites like ammonia, branched-chain fatty acids, ethanol,
organic acids, hydrogen sulfide etc. Several of those latter (ammonia,
hydrogen sulfide and p-cresol) are inhibitor of colonocyte
respiration when present in excess. In addition, p-cresol acts as a
genotoxic compound on colonocytes. Our recent results show that
HP diet consumption modifies the morphology of colonocytes and the
distribution of mucous cells in the colonic crypts. Lastly, by
using a transcriptomic approach, we noticed that the HP diet modifies in
colonocytes the expression of genes related to several cellular
functions including apoptosis, cellular architecture, adhesion, immunity
and DNA-damage-related events. Our team as part of a
European research project consortium has undertaken a study on the
effects of 3 weeks-HP diet ingestion in overweight volunteers.</p>
