摘要

Recent epidemiological evidence suggests that consumption of diets high in red or processed meats and low in dietary fibre may contribute to the high incidence of colorectal disease in western societies. To increase our understanding of the dietary factors which could contribute to colorectal diseases we have carried out a series of studies using rats to examine the effects of consuming high levels of a range of different dietary proteins, with and without resistant starch (RS), on colonic health markers. We have shown that dietary protein sources differ in their capacity to increase colonic DNA damage and mucus barrier thinning but that inclusion of RS in the diet protected completely or partly against these effects. High levels of dietary casein increased DNA damage but the damage was not as great as for cooked beef or a soy isolate. A whey protein isolate did not increase colonic DNA damage when consumed at high levels. Our results suggest that dietary protein of dairy origin may be less harmful to the integrity of the large bowel than a number of other protein sources and also that addition of RS to the diet appears to counteract protein-induced damage irrespective of the source.
