High-fibre diet reduces risk of breast cancer by 25%, research suggests
US study examined food intake of more than 2,000 women living with and beyond breast cancer
The relationship between dietary fibre and roughage-rich foods and a reduced breast cancer risk has been explored previously, but often conducted within largely non-Hispanic white women populations. However, the association with specific tumour subtypes as defined by their hormonal receptivity or the multi-ethnic population is less well known.
This American study examined the food intake of an eligible group of participants previously included in a population-based case control investigation, the San Francisco Bay Area Breast Cancer study, which was conducted between 1995-2004.
Analysis was conducted of data from more than 2,000 women living with and beyond breast cancer – including 1,070 Hispanics, 493 African Americans and 572 non-Hispanic whites – with a correspondingly similar control group of women without cancer.
