A new study has linked high dietary fibre with a reduced risk of breast cancer. The study of over 90,000 women compared the incidence of breast cancer in those who had diets high in fibrous foods (such as potatoes) with those who consumed less.

The risk of breast cancer was 12%-19% lower in young women with higher fibre diets. High intake during adolescence was also associated with 24% lower risk of breast cancer before menopause. Among all the women, the relationship between fibre intake and breast cancer risk reduction was the same: the greater the intake, the greater the reduction in breast cancer risk. Fibre from vegetable and fruit sources had the most obvious benefits.

The reasons for this effect are not yet completely understood but the study authors have suggested that fibre-rich foods reduce oestrogen levels and high oestrogen levels are associated with breast cancer development.

Women from the African and African-Caribbean community have already been noted to have poorer outcomes in relation to breast cancer when compared to white women.  It has also been reported that Black women tend to develop breast cancer earlier. Increasing dietary fibre certainly appears to be another weapon in the fight against breast cancer.
