Are we living in a toxic environment? The experts at Canyon Ranch ask us to consider these facts:

• The EPA estimates that 4.7 billion pounds of toxic chemicals are released into the environment annually.
• It's likely that 25 percent of the U.S. population suffers from some level of heavy metal poisoning.
• Fourteen pounds of food colorings, additives, preservatives, emulsifiers, and flavorings are consumed per person each year.

Toxic? Maybe. At minimum, though, we are living in a world filled with chemicals, pesticides, additives, preservatives, antibiotic and hormone residues, and heavy metals. Whether consumed, inhaled, or absorbed, our bodies soak this stuff up. In order to reduce the load, and the toll it takes it takes on our health, there's something we can do. We can eat clean. Here's how:

I'm a little tired of reading and writing about sunscreen. Maybe it's not the actual reading and writing that has me worn out. Maybe it's the realization that I keep reading and writing about sunscreen yet the information is just not sinking in with the masses of sun-hungry people out there -- according to the EPA, there has been a staggering 1,800 percent increase in malignant melanoma cases since 1930. Recent figures show a shocking rise in skin cancers among those in their 20s and 30s.

The experts at Canyon Ranch are weighing in on sunscreen. So here I go again, with some more about this tiring topic.

• Sunscreen contains unique chemical components which absorb ultraviolet (UV) light. When applied to the skin, the chemical molecules form an invisible, protective layer that repels the penetrating UV rays. It also helps prevent premature aging and pre-cancerous growths.

I'm still on a quest for guidance on the whole fish topic. The same few questions keep cycling through my head. How often should I eat fish? What kind of fish should I eat? What are the real health dangers surrounding fish consumption? I keep searching for answers. And now and then, I catch some good advice about the topic.

If you find yourself floundering at times, like me, here are seven tips you might find helpful.

• The National Academy of Sciences, the American Heart Association, and the World Health Organization all encourage regular fish consumption. Sure, there are legitimate concerns about environmental issues, but experts still say the benefits of eating a variety of fish far outweigh the risks. Eating fish protects the heart and reduces the risk for Alzheimer's disease, arthritis, strokes, depression, bipolar disorder, and our favorite topic here at this site: cancer.

Environmental groups claim some children's bath products contain a suspected cancer-causing chemical in amounts that reach or exceed safe limits. The chemical in question -- 1,4-dioxane -- is found in products made by companies such as Johnson and Johnson, Disney, Kimberly-Clark, and Gerber, says David Steinman, head of the environmental publishing company Freedom Press.

The Environmental Protection Agency (EPA) calls this chemical, already known to cause cancer in animals, a probable human carcinogen. But there is no real regulation on the petroleum-derived chemical and the Food and Drug Administration (FDA) only recommends cosmetic companies limit the concentration of 1,4-dioxane to 10 parts per million (ppm).

Studies show Johnson's Kids Shampoo Watermelon Explosion contains the maximum recommended level of 10 ppm. They also reveal that Kid Care's Hello Kitty Bubble Bath contains 12.3 ppm of the chemical. And two adult shampoos have been found to have twice the recommended level of this chemical that is typically a manufacturing by-product.

It's been reported that nearly 57 percent of all baby soaps contain 1,4-dioxane. But Iris Grossman, director of communications at Johnson and Johnson, stresses that all of her products are within FDA limits.

Cancer is not the only risky link to children's bath products. It seems these items are also linked to early puberty development. And this is concerning because a fast-paced growth rate combined with children's porous skin increases susceptibility to toxins that can enter the bloodstream. One breast cancer expert says an increase in breast cancer risk is linked to toxic exposures during the formative years of life.

The typical Western diet is lacking in a healthy balance of omega-3 fatty acids to omega-6 fatty acids, and for men with prostate cancer, this can have adverse consequences in controlling tumor growth and PSA levels. In this part of the world, our diet offers too little in the way of omega-3 and too much in the way of omega-6. Researchers found that by balancing the ratio in increasing omega-3 and decreasing omega-6 in the diet, there were able to slow tumor cell growth rates by 22 percent and lower PSA levels a whopping 77 percent.

Omega-3 fatty acids are found in leafy green vegetables, nuts, vegetable oils such as canola and soy, flaxseed, flaxseed oil, olive oil, cold-water fish like salmon, mackerel, sardines and fresh tuna. Omega-6 fatty acids are found in corn, safflower oils, food products made with corn oil (think processed foods and fast foods) and red meats.

According to UCLA researchers, when the fatty acids are not in the right ratio to each other, omega-6 creates an inflammatory response in the body that can promote the growth of tumors, while omega-3 has the opposite effect in acting as an anti-inflammatory.

"This is one of the first studies showing changes in diet can impact the inflammatory response that may play a role in prostate cancer tumor growth," said principal investigator Dr. William Aronson. "We may be able to use EPA and DHA supplements while also reducing omega-6 fatty acids in the diet as a cancer prevention tool or possibly to reduce progression in men with prostate cancer."

These studies were done on animal models, and not humans, but the researchers did use a special mouse model for hormone-sensitive prostate cancer that matched closely prostate cancer in men.

The National Academies' National Research Council has published a 379-page report on trichloroethylene (TCE) link to cancer and other health risks from TCE exposure has strengthened since the 2001 U.S. Environmental Protection Agency (EPA) draft risk assessment.

Based on information provided by the National Academies, at the time, the EPA was blocked from elevating its assessment of the chemical's risks in people by the Defense Department, Energy Department and NASA, all of which have sites polluted with TCE.

TCE, a solvent used to remove grease from metal parts in airplanes and to clean fuel lines at missile sites is contaminating air, soil, and water at several military installations and hundreds of waste sites around the country.

Until the mid-1970s, it also was used as a surgical anesthetic. TCE can be found in typewriter correction fluid, paint removers, adhesives, and spot removers. According to the report, TCE has also been found at about 60 percent of the nation's worst contaminated sites in the Superfund cleanup program.

Michael Fumento is an author, journalist, and attorney specializing in science and health issues. And he has a lot to say about the Surgeon General's recent announcement that the second-hand smoke debate is over -- that second-hand smoke does in fact kill. Fumento believes that the debate is over means if you have your doubts, then keep them to yourself -- that the topic is not up for discussion any longer. But Fumento states that we should definitely have doubts -- about the effects of second-hand smoke and about what the Surgeon General has to say about it.

The image in the photo of diesel exhaust pouring out of the back of the big yellow school bus makes me want to cough and I am no where near the back of the bus. Imagine the children sitting inside the bus, where much of that bus diesel's own exhaust is entering back inside the cabin from cracks in the exhaust train and through windows and doors. Two environmental groups imagined it -- and based on disturbing studies of the effects on school children from the 40 different chemicals classified as toxic contaminants that make up diesel exhaust -- have filed a lawsuit in California to force Laidlaw Transit Inc., of Naperville, Illinois, to put written warnings on buses about the dangers of cancer-causing pollutants the buses emit. Air pollution from diesel exhaust is a known carcinogen. The State of California knows it. The EPA knows it.
