New Study: Saturated Fat Linked To Breast Cancer Mortality

Butter and knifeDietary Fat And Breast Cancer Mortality: A Systematic Review And Meta-analysis, Critical Reviews in Food Science and Nutrition, 18 February 2015

Results: Breast cancer specific death (n = 5; HR = 1.63; 95% CI: 1.19, 2.24; p < 0.01) was higher for women in the highest versus lowest category of saturated fat intake.

Conclusions: These meta-analyses have shown that saturated fat intake negatively impacts upon breast cancer survival.

That was deaths from breast cancer. A study from last April found saturated fat linked to the development of breast cancer. It was a large (n = 337,327, part of the EPIC cohort from 10 European countries), long-term (11.5 years) prospective study:

Dietary Fat Intake And Development of Specific Breast Cancer Subtypes, Journal of the National Cancer Institute, April 2014

High total and saturated fat were associated with greater risk of estrogen-receptor- and progesterone-receptor-positive disease. … High saturated fat was statistically significantly associated with greater risk of HER2- [human epidermal growth factor 2 receptor-negative] disease.

Conclusion: High saturated fat intake particularly increases risk of receptor-positive disease, suggesting saturated fat involvement in the etiology of this breast cancer subtype.

Most of the saturated fat in our diet comes from animal foods … cheese, yogurt, milk, meat, butter, poultry, eggs. People who are increasing intake of these foods are doing so at their own peril.

On a related note … Saturated fat is also one of the best sources for persistent organic pollutants (POPs) in our diet. POPs are found in high levels in the fat of animals because these pollutants are often fat-soluble and they bioaccumulate. POPs have been implicated in a number of chronic diseases – heart disease, cancer, diabetes.
