556 - ‘Evolutionary perspective on dietary intake of fibre and colorectal cancer’. European journal of clinical nutrition. 61(1), pp.140-142

Summary

Abstract

From an evolutionary perspective, the ongoing discussion of fibre’s role in colorectal cancer is possibly limited by the overall low intake of fibre across study groups. Our ancestral diet consistently included a diverse range of plants that regularly contributed up to and often 4100g/day of dietary fibre. Importantly, this diversity assured that, owing to a range of physical and chemical structures, a steady flow of fermentable substrates promoted metabolic activity into the distal regions of the colon.

Significance for a baker:

This study highlights the diversity of fibre that was present in the human diet in the past, and how this has now changed. Researching the role of fibre in colorectal cancer is difficult because of the general low levels of fibre in the diets of those in the study groups. To increase diversity of fibre in your diet, use the Botanical Blends in your baking and follow some of our recipes for eating symbiotically.
