Raw fats have much better cleansing / detoxification properties than heated fats. Also all poly-unsaturated fats (and also mono-unsaturated) fats are damaged by heating and cause massive amounts of free radicals.
+ Raw foods contain less free radicals
Heating increases chemical reaction speed and significantly increases the forming of free radicals.
