A Relationship Between Diet And Breast Cancer Survival?

A recent study in the journal Cancer takes a leap forward in defining the role of diet in a woman's survival after the diagnosis of breast cancer.

In the study, a group of 1,982 female registered nurses completed a food frequency questionnaire after being diagnosed with invasive breast cancer between 1976 and 1990. The questionnaire assessed their intake of 83 different nutrients, total calories, and alcohol. Of particular interest to researchers was the intake of fat, vitamin A, and alcohol, because these dietary factors were hypothesized to have an association with survival.

Surprisingly, the study found no significant association between fat intake and risk of death. Although the risk of death was slightly elevated in those with the highest fat intake compared with those with the lowest, the result was not found to be statistically significant. Likewise, intake of vitamin A and moderate alcohol consumption showed no clear relationship to death rates. Furthermore, there was little association between risk of death and intake of red meat, fruit, and grain-based products.

Increased survival was observed among women who ate more protein and poultry. Compared with those with the lowest intake, women with the highest intake of protein had a 35 percent lower risk of death. A 30 percent reduction in mortality was observed in women with the highest intake of poultry compared with women with the lowest intake of poultry. Since no association was seen with red meat, the associations observed for protein are most likely due to intake of poultry and dairy products.

The protein and poultry findings were strongest in women who had no metastatic disease, although the association also existed in women with metastases. The reasons for increased survival among women eating more protein and poultry are unknown.
