A diet high in vegetables, fruits and soya cuts the risk of developing breast cancer by 30 percent.
A diet high in vegetables, fruits and soya cuts the risk of developing breast cancer by 30 percent.
Previous studies in Asian populations show positive effects of soya-rich food against breast cancer risk. To study whether the protective effect is due to soya alone or its combination with other dietary factors, the researchers used data collected between 1993 and 1995 from 63,257 men and women in the Singapore Chinese Health Study (SCHS). The study used in-person interviews to gather information about diet, weight, education, smoking and exercise habits, and hormone use.
The SCHS data allowed the researchers to identify two dietary patterns: the meat-starch-saturated-fat based meat-dim-sum pattern and the vegetable-fruit-soya pattern characterised by lots of cruciferous vegetables such as broccoli, cauliflower, sprouts, kale and cabbage. Based on their self-reported intake of 165 foods, participants were assigned a score for the vegetable-fruit-soya and the meat-dim-sum dietary patterns.
A total of 34,028 women were identified with no history of breast cancer within the study group. All women were between the ages of 45 and 74 years. For the most part, they were thin, they exercised, had gone through menopause, and few smoked or used hormone replacement therapy.
By the end of 2005, 10 years after the enrollment interviews, 629 breast cancer cases had been identified in the Singapore Cancer Registry among study participants.
After analysing the data, it was found that the greater the intake of vegetables, fruits and soya, the lower the breast cancer risk among post-menopausal women. The researchers did not find an association between higher meat-dim-sum consumption and increased breast cancer risk, as suggested in other studies.
The above findings support that a diet rich in vegetables, fruits and soya protects against breast cancer risk.
