Research published in BMJ Open last November, strongly suggests that there may be a link between synthetic estrogen from oral contraceptives that has found its way into the environment and the rising rate of prostate cancer among men around the world.

In our concluding segment on the immune system, we progressively step outside the box and draw a clear line between the medical view of the immune system and the holistic view. And ultimately, we arrive at the primary point of separation.

A study from the University of Washington has found yet another strike against substances that launder your clothing. It turns out that using the most popular brands of scented laundry detergent leads to dangerous emissions that come out the vent when running clothing through the dryer.

Perhaps you've seen the headlines: "Colon Cleansing Ineffective and Unsafe, Say Researchers." So what is this groundbreaking study in the Journal of Family Practice that has definitively driven the nail in the coffin of colon cleansing and got people so worked up?

A just-released report by the Natural Resources Defense Council and the National Disease Clusters Alliance identifies 42 "disease clusters" in the US, spread out among 13 states. Certainly, the existence of disease clusters gives new meaning to the realtor's favorite chant: "location, location, location." Even the nicest neighborhoods can be subject to contamination, and people often don't know that they're living in a toxic zone until it's too late -- until they've already had exposure, or worse, gotten sick.

There is some degree of risk, no matter how small, that substantial amounts of radiation may leak from one or more of the Japanese reactors, make its way into the upper atmosphere or down into the water, and ultimately affect the United States and the rest of the world. The amount of exposure to citizens outside of Japan would ultimately be small; but unfortunately, in the case of some types of radiation, small amounts of radiation exposure -- from meat, dairy, water -- can still have health consequences, particularly for the vulnerable. In this Part II Podcast series on Japan's Nuclear Reactors, learn what you can do to protect yourself from nuclear fallout.

In this segment, Jon Barron's health podcast discusses the recent Japanese nuclear incidents, which Jon points out are unlikely to have any significant health consequences outside of Japan. However low risk is not no risk – so Jon details how a natural detox program can provide a level of protection against radioactive fallout.  Listen for more information about radioactive elements, what you need to know about radioactive iodine, how to take Iodide if ever needed, how to avoid hypothyroidism, and what other natural health precautions you might want to take -- for yourself and your children -- if nuclear fallout from Japan ever becomes a health hazard in your area.

If your home is your sanctuary, you might want to reconsider what you decorate it with, especially if you plan to get pregnant. A recent study out of the School of Public Health at the University of California in Berkeley has found that chemicals commonly used to fire-proof furniture, textiles, plastics and electronics manage to get into the bloodstream and apparently, exert a powerful influence on fertility.

The Safe Water Drinking Act regulates 91 chemicals, but at this point, the US uses over 60,000 chemicals, and trace amounts of at least some of those end up in the water supply, without any law in place to regulate them. Find out what's really in your tap water at home.
