Researchers have found more reasons for us to eat our fruit and vege, by identifying fibre as a vehicle for delivering antioxidants to the large bowel which may then protect against bowel cancer.
 
Long known for its benefits as a 'bowel cleaner', this latest research has found that fibre also binds up to 80 per cent of polyphenols (a type of antioxidant) in fruit and vegetables so it is not digested in the stomach and intestine.
 
"Fibre is able to safely and effectively transport polyphenols to the colon (large bowel) where these compounds may have a protective effect on colon health as they are released during plant fibre fermentation by gut bacteria," said Dr Anneline Padayachee, The University of Queensland.
 
Cells in fruit and vegetables 'open' up when they are juiced, pureed or chewed, allowing important nutrients to be released.
 
The beneficial fibre is found in the pulp of fruit and vegetables that some people discard.
 
"In juicing, the fibrous pulp is usually discarded, which means you miss out on the health benefits of these antioxidants as well as the fibre," Dr Padayachee said.
 
Dietary fibre is mainly needed to keep the digestive system healthy. There is a 30g recommended daily intake of fibre for men and 25g for women.
 
Dr Padayachee's research was presented at Fresh Science and was a joint project between The University of Queensland and CSIRO.
