  1. Diet and breast cancer in Shanghai and Tianjin, China.

    Article - En anglais

    Various aspects of adult diet have been linked to breast cancer development.

    These include intake of fat (risk factor), and intake of fibre, soy protein and vitamins A, C and E (protective factors).

    All interviews were conducted in person.

    Findings from the two studies were similar, although the diets in Shanghai and Tianjin were different in many respects.

    Cases and controls were similar in their consumption of soy protein, measured either in absolute levels or as percentages of total protein.

    Overall, all components of dietary fat showed a modest, non-significant association with breast cancer after adjustment for energy intake and other non-dietary risk factors for breast cancer.

    Intake of crude fibre, carotene and vitamin C, on the other hand, exhibited strong, statistically significant inverse associations with breast cancer risk.

    The last three indices were highly correlated, rendering it impossible to disentangle their individual effects ; they were closely associated with intake of green vegetables in the two study populations.

    Our data indicate a strong protective effect against breast cancer development with intake of foods rich in fibre, vitamin C and carotene.

    Our results are also compatible with dietary fat having a modest, positive effect on breast cancer risk within the range of exposure experienced by women in China.

    Our study does not support the hypothesis that high intake of soy protein protects against breast cancer.
