Dr John Gray (PhD) (the guy who wrote Men are from Mars, Women are from Venus?) has been researching the effects of hormones in food (among other things). Says: feminine hormones given to cattle to fatten them up lower the levels of testosterone in men, causing dysfunction, depression, lethargia and obesity. Estrogen’s effect on men causes ‘Grumpy old man syndrome’, lowers levels of testosterone, diables libido and makes men cranky.
He also says that Omega 3 stimulates brain activity, turns you on; while Omega 6 (vegetable oil) neutralizes the Omega 3, turns your brain off. Omega 9 (olive oil) is an anti-inflamatory.
Dr John Gray’s web site looks very commercial, but maybe you can get something out of something there..:
