Whether anyone shows signs of xenoestrogen dominance or not (the effects are more related to the balance of (xeno)estrogen with progesterone (or testosterone), rather than the absolute level of (xeno)estrogen), it is wise to notably reduce one's exposure to xenoestrogens. Ideally this means eating a Mediterranean diet of organic foods. (And watch out for mercury in fish!). Also, stay active. Do some mild aerobic exercises every day for at least 15 minutes. Good circulation solves a ton of ailments.
Also, note that xenoestrogens are fat soluble. They'll show up in the oils & fats. So try to especially use organic olive oil (in that Mediterranean diet), and especially keep your meats organic (which shouldn't hit your pocket book too hard since that diet is low in meat, especially red meat). Fat solubility also means that (xeno)estrogen rides on the surface of red cells rather than in the plasma--most labs look for it (as well as other fat-soluble hormones like progesterone and testosterone) in the plasma. A saliva test is most accurate for (xeno)estrogens and ~I think~ also for progesterone & testosterone (but I could be wrong about that).
That site I cited with all the references also explains how natural progesterone can mostly counteract many effects of xenoestrogens (assuming that is your problem, jekertee--fair chance it isn't!). This is because much of the effect results from the imbalance in the ratio of progesterone (or testosterone) with (xeno)estrogen. Natural progesterone is available in low-dosage over the counter (make sure its real--there's a list of sources on that site). It absorbs through the skin far better than when it is taken internally, so it comes as a cream. Men can also take it when there is evidence of xenoestrogen problems.
Those many references on that page proving the damage of xenoestrogens are all reputable (please test what I say), and Lee has no association with any marketer of progesterone. Lee is not the only one touting this. There are quite a few doctors in my town of 150k that highly recommend his books. Lee has really been simply the collector and publisher of evidence that has gradually come to light over the last couple decades.
Most doctors just don't have time to study the literature. So their main source of information is the pharmaceutical salesmen. And guess what. Natural substances cannot be patented. Thus the companies do everything in their power to defend the unatural remedies and slander the natural--and those companies are quite powerful in government and in academia. Don't get me wrong. Modern medicine has saved my life at least twice and the lives of several of my loved ones. But that doesn't mean it can't stand any improvement in certain areas!
