Breast cancer linked to animal fat intake again

Breast cancer linked to animal fat intake again

This is not ‘new news’ as such as this link has been found many times in rigorous research but here it is again in a brand new study.

What did this latest study uncover?

  • A high intake of dietary fat - particularly saturated fat from animal foods - was associated with a greater risk of estrogen receptor-positive and progesterone receptor-positive breast cancer
  • A high saturated fat intake was statistically significantly associated with a greater risk of HER2-negative disease
  • All intake quintiles of saturated fats were associated with a statistically significant greater risk of HER2-negative breast cancer
  • One of the main strengths of the study is that it took into account breast cancer subtypes
  • “The results support our original finding that high saturated fat intake is statistically significantly associated with increased breast cancer risk

“The theory that high consumption of fat increased the risk of breast cancer has been around since the 1970’s.  The early research suggesting that fat intake might have a causative effect on breast cancer was based on feeding fat to lab animals - such as rodents - and noting the development of mammary tumors.  And there was an ecological study where they charted out breast cancer rates in all different parts of the world and also charted out per-capita fat intake, and there was a perfect slope” [meaning that breast cancer rates appeared to rise with dietary fat consumption].  We kept saying ‘There’s so much support for the role of dietary fat…”
