well after reading back through some of my saved files on nutrition, neither of us were really accurate.
monounsaturated fats and saturated fats boost testosterone about equally, while polyunsaturated fats do not increase testosterone.
however! since most sources of saturated fat are also sources of cholestrol, and since cholestrol is the precursor to testosterone and increased cholestrol consumption increases testosterone levels, that would mean on average most saturated fat sources would yeild better increases in testosterone than most monounsaturated fats.
as far as the pro inflammatory effect of fats. well, for one, the fact that okinawans have much better overall health than us, would probably be directly causedby the fact that their diet is very anti inflammatory, as a huge number of diseases and health conditions are from inflammatory diet. hence why experts preach that the overuse of corn oil (highly inflammatory fat) in the foods people are eating today is a major contributor to disease and illness.
as far as bodybuilding is concerned, the consumption of inflammatory fats is beneficial to increase and optimize inflamatory response to training, leading to increased production of prostaglandin pgf2a, which means more growth (and more fat loss/inhibition of fat gain).
