Just wanted to show you the following study that I stumbled upon (link).
It looked at the differential effects of fatty acids on Vitamin K2 absorption in the bowel of rats. It found that while the saturated acids butyric (C4:0), octanoic (C8:0) and stearic (C18:0) inhibited K2 absorption only in the ileum the unsaturated acids oleic (18:1) and linoleic (18:2) inhibited Vitamin K2 absorption in both ileum and colon. Comparing oleic and linoleic, linoleic appeared to be a greater inhibitor of Vitamin K2 absorption.
A study made in humans, that compared corn oil with olive oil/sunflower oil mixtures came to a similar conclusion (link).
Hence, apart from lipid peroxidation in the body, unsaturated fats (especially the PUFA linoleic acid), in contrast to SFA, may be deleterious by causing a Vitamin K2 deficiency if consumed in high amounts.
