Nutrition and Breast Health

Last time here we briefly reviewed your risk of breast cancer, based only on demographics, on statistics. These  included the genetic component – family- that contributes to breast cancer. However, even if you have a statistical risk, even if you have a genetic risk, for breast cancer, you CAN modify your risk.

You can reduce your risk! 

This article provides tips on reducing your risk of breast cancer.

  • Diets high in polyunsaturated or monounsaturated fat do not increase breast cancer risk.
    (Published by the American Institute for Cancer Research)
  • Diets high in saturated fat do seem to increase the risk for breast cancer.
  • Diets with a high intake of animal fat, especially from red meat and dairy foods, during pre-menopausal years are associated with an increased risk of breast cancer.
    (Published in Journal of the National Cancer Institute 2003)
  • Canadian Cohort Study:  Women who consumed high amounts of fiber had a 30% reduction in breast cancer risk.
  • Nurses Health Study:
    Consumption of 5 or more servings of fruits and vegetables is associated with a lower risk of pre-menopausal breast cancer.

Optimize Your Breast Health:  Most Beneficial Diet is …

  • Rich in fruits, vegetables, whole grains, low-fat diary.
  • Includes fish and poultry several times a week; red meat only several times a month.
  • Rich in monounsaturated and polyunsaturated fats, with emphasis on olive oil.
  • Recent studies indicate that a diet high in B-carotene and vitamin C is associated with a protective effect on the incidence of breast cancer, especially in those women taking exogenous hormones or those who have a moderate to high alcohol intake.

It’s not entirely black-and-white, and not entirely simple:

  • Studies with phytoestrogens/soy have been conflicting.
  • The consensus seems to be:
    Phytoestrogen/soy consumption early in life has a protective effect against breast cancer, but consumption later in life may not.
  • A recent study (The Shanghai Breast Cancer Survival Study) concluded that soy intake is associated with lower mortality and recurrence among breast cancer patients.
  • This association follows a linear dose-response pattern until soy food intake reached 11 g/d, regardless of tamoxifen usage.

Published in the journal, JAMA December 2009

Our conclusion? Women with a history of breast cancer should not be concerned about soy ingestion.

And there’s more:

  • Cruciferous vegetables (such as broccoli, cauliflower, brussel sprouts, kale, collards, bok choy and cabbage) have high concentrations of indol-3-carbinol, which has been shown to prevent the development of estrogen-enhanced cancers of the breast, endometrium and cervix.

  • Flax is a significant source of lignans, which may have a protective effect on breast cancer.
  • Green tea contains polyphenols, antioxidant compounds that reduce the risk of breast and other types of cancer.
