Why Is Butter Bad? Part II

Posted May 22 2013 10:04pm

To test my idea about the unsaturated-to-saturated fat ratio being important for cardiovascular health, I wanted to focus in on this study .  This study, unlike other ones I’ve cited, directly compares oil to oil.  It tests butter versus olive oil in diabetes patients.


So there you have it, butter substantially reduces flow-mediated dilation (FMD), while olive oil is generally neutral.

If you calculate the unsaturated-to-saturated fat ratio for the two meals used in the study, you get:

  • Butter  0.5:1
  • Olive Oil  5.8:1

Very different ratios, and very different results on vascular health.
