New study finds that you don't have to overeat to become obese.


Pollution contaminates our water, air, and land. It has been proven to cause asthma, allergies, cancer, emphysema, and whole host of other diseases. It causes global warming, kills our wildlife and now scientist from the Environmental Epidemiology at the Institut Municipal Investigacio Medica in Barcelona discovered it causes OBESITY.  

So in addition to fast foods and processed foods, pollution causes obesity? The Spanish study revealed that children who were exposed to a range of common chemicals and pesticides in the womb increased the childs chances of becoming obese. 

As reported in the journal Acta Paediatrica, scientists looked at the concentration of hexachloreobenzene (HCB) in the umbilical cord blood of 405 children born in Menorca from mid-1997 to mid-1998. Among those data point collected post birth, scientists looked at infant height and weight.  Feeding practices were reported by mothers in interviews at six months and one year after birth.  Additionally, the children’s height and weight were measured when they were 6.5 years old. The study revealed that children with the highest exposure to HCB were 2.5 times more likely to be overweight. The researchers also reported that these children were three times more likely to be obese than those with lower exposure levels. 

So, what is HCB? Hexachlorobenzene is a fungicide formerly used to treat seeds to control fungal disease. It was banned globally in the '90s under the Stockholm Convention which banned chemical substances that accumulate through the food chain, and pose a risk of causing adverse effects to human health and the environment. HCB has been banned in the US since 1965 but can still be found in our environment in 84 Superfund sites in the US and all across the world. It is a known animal cancinogen and a probable human carcinogen. Studies have found that HCB accumulates as your move up the food chain. Just like mercury, as it goes up the seafood food chain, HCB concentrations increase. Therefore, if you eat a large fish like tuna or swordfish that has been contaminated up the food chain, the concentrations of HCB would be extremely high.

So what else have children been exposed to prior to being born, and what impact might it have on my kids?

Previous studies have linked bisphenol A exposure to obesity in animals, and other studies have linked phthalates to obesity in adult men. As reported in the Telegraph in the United Kingdom, "The report's authors are now calling for exposure to similar pesticides to be minimised, including bisphenol A (BPA), used in baby bottles and cans of food, and phthalates, found in cosmetics and shampoos." Tests have shown BPA is found in 95% of Americans, while 90% have been found to be exposed to phthalates in the womb.

Between BPA, HCB, and phthalates, I'm frustrated and concerned. I would prefer to screw my kids up on my own and not worry about what their sippy cups or shampoos are made of, or what banned fungicides are in their foods.

What's keeping you up at night?

Cancer or Germs? I'll take the germs.

I must admit that in my house we might be thought to be a little lax when it comes to germs. I am not saying that we do not wash our hands when we go to the bathroom or before we eat. We play in the yard digging for bugs and worms and get big slobbery kisses from our dog. We are not afraid of dirt, and follow the "five second rule".  That said, we are a very clean family. We focus on washing our hands to ensure that there is no, as my 2 year says, durt when we touch food.  

Now, I have never been big on anti-bacterial soaps and hand sanitizer because I believe that we need to build up our immunity to bacteria and viruses to make us stronger. When the kids were infants I did use these types of cleaning products but now that they are older, these products are basically non-existent in our house.  

So when I was asked to test out a new, natural, non-toxic hand sanitizer, I was little disinterested but began a dialogue with the company because I was willing to learn more. One of the key points of this new product was they do not use triclosan a widely used anti-bacterial agent. 

What is triclosan you ask?  Well, this is what I learned and it is not a pleasant story...

Triclosan is antimicrobial and antifungal pesticide that is used in a wide variety of products found in retail stores across the country including soaps, toothpastes, cosmetics, deodorants, personal care products, first aid, kitchenware, computer electronics, toys, plastics, paints and clothing. It is widely known as Microban which is infused into everything from cutting boards, pillows and shoes because it inhibits the growth of microbes, such as bacteria, mold and mildew.  Ok, that does not sound that bad...yet.

However, according to Beyond Pesticides, a group dedicated to eliminating toxic and harmful pesticides from our environment, "Studies have increasingly linked one of the most common antimicrobial, triclosan (and its chemical cousin triclocarban), to a range of adverse health and environmental effects, from skin irritation, allergy susceptibility, bacterial and compounded antibiotic resistant, tainted water, and dioxin contamination to destruction of fragile aquatic ecosystems."  

As explained on Wikipedia
During wastewater treatment, a portion of triclosan is degraded while the remaining adsorbs to sewage sludge or exits the plant in wastewater effluent. In the environment, triclosan may be degraded by microorganisms or react with sunlight forming other compounds which may include chlorophenols and dioxin, or it may adsorb to particles that settle out of the water column and form sediment. Triclosan was found in Greifensee, a small lake in Switzerland, sediment that was over 30 years old, suggesting that triclosan is degraded or removed slowly in sediment.
Whoa....wait a minute,  Triclosan degrades into dioxins and chlorophenols, both are known carcinogens. Studies have shown that ultraviolet light converts triclosan to dioxins and it is believed that sunlight could transform triclosan to dioxins naturally. Scientist at the Virginia Polytechnic Institute and State University in Blacksburg, VA tested 16 products including soaps, lotions and body wash with triclosan and without.  They discovered that the triclosan products reacted with chlorinated water to produce chloroform, another carcinogen.  So this stuff breaks down into cancer causing agents. I think we'll keep our hands a bit dirtier and live longer.

In a press release from the Environmental Working Group, the organization states:
Triclosan has been linked to cancer in lab animals, has been targeted for removal from some stores in Europe for its health and environmental risks, and the American Medical Association recommends against its use in the home. It is also linked to liver and inhalation toxicity, and low levels of triclosan may disrupt the thyroid hormone system. Thyroid hormones are essential to proper growth and development, particularly for brain growth in utero and during infancy.

Triclosan breaks down into very toxic chemicals, including a form of dioxin; methyl triclosan, which is acutely toxic to aquatic life; and chloroform, a carcinogen formed when triclosan mixes with tap water that has been treated with chlorine. Scientists surveyed 85 U.S. rivers and streams, and found traces of triclosan in more than half.
Just last month, Beyond Pesticides, along with Food and Water Watch, Greenpeace US, Natural Resources Defense Council, Sierra Club and dozens of public health and environmental groups filed a comment/letter with the Environmental Protection Agency, urging the the agency to stop all non-medical use of triclosan because of its detromental effects on our health and the environment. You can read the press release and comments submitted to the EPA by clicking here and here

As I mentioned, triclosan can be found in many, many everyday products. To see a detailed list of products and brands, check out the list on Beyond Pesticides by clicking here. Some very well known brands are on the list like Colgate Total toothpaste. Toothpaste? How scary is that? You are putting triclosan and therefore carcinogens directly into your mouth and your body! So rinse and spit, and now you have chloroform. The Colgate website touts "Colgate Total® formula is so revolutionary it's even patented. One of its active ingredients is triclosan, which is used to help prevent plaque and gingivitis. The formula's copolymer enables triclosan to continue working in the mouth for 12 hours." Great so use this toothpaste and triclosan will stay in your mouth for 12 hours!  That's 12 more hours of exposure to a potential cancer causing agent than I want.

So how do we get rid of those unwanted germs when we really need to. Well let's go back to that product I dismissed at first. It is called Clean Well made from Ingenium, a natural germ killing product derived from thyme and other essential oils. According to the company, Clean Well kills 99.99% of germs on contact including E. Coli, Salmonella, Staph (MRSA) and Pseudomonas. Clean Well is made from a renewable resource that is sustainably grown with no pesticides, irrigation or fertilizer and there are no toxic byproducts from the manufacturing process. Clean Well comes in a spray, as hand wipes and hand wash foam.  So for when you have a house full of sick kids or are cooking with chicken and want to kill germs, you now can avoid triclosan. 

To read more about triclosan check out the Environmental Working Group site where they give detailed information on the effects of triclosan on our health and the environment, what products contain triclosan and much, much more. 

Those germs don't look so bad anymore....you gonna give up your anti-bacterial soaps, or are you gonna to keep on using triclosan-based products?

Another Point for the Organic Industry!

For years I've been a big supporter of the organic movement. But recently I made a decision to make a change in my buying behaviors and bring my beliefs into my home. Now, it is hard to find food in my house that is not organic. There so many reasons to purchase organic foods, first and foremost, organic foods are better for the environment and of equal importance, better for you health.

Just last month, I wrote about a study that revealed that the pesticides applied to industrial fruit and veggies enter our bodies and show up in our saliva and urine. Happily, this is not a permanent problem.  Once you switch to organic produce you can "get clean".  The same study showed that after switch to organic foods, the industrial pesticides were no longer present if your body within 8-36 hours after switch. You can my earlier post on this topic here

If that isn't enough to change your buying habits, two more studies on organic foods were published last week that are sure to make you rethink your food choices.

The first study, from the Organic Center was entitled "New Evidence Confirms the Nutritional Superiority of Plant-Based Organic Foods." The report compared the nutrient content in conventional vs. organic foods, based on the findings of 97 published studies. The study revealed the following:
  • Organic plant-based foods are on average, more nutritious in terms of their nutrient density for compounds.
  • The average serving of organic plant-based food contains about 25% more nutrients compared with the same food produced by conventional farming methods.
  • There is strong evidence that poultry and livestock that consume organic feed produce meat, milk and eggs that are more nutritious. 
So plainly said, organic food is healthier for you, and has more nutrients per serving.  

Studies like this make me feel all that much better about buying organic. It is better for me to eat "green,"  but is it better for the farmer?

So the first question here is, do you care? I do, and the reason why is that unless farmers can be as productive and profitable growing organic, I won't be able to buy the foods I want to. So, is organic farming a smart business decision for Farmer John?

Yes! Scientists at the University of Wisconsin-Madison conducted a study to see if organic farms can be as productive as conventional industrial farming systems.  As reported in the March-April issue of the Agronomy Journal, "The answer is an unqualified, "Yes" for alfalfa or wheat and a qualified "Yes most of the time" for corn and soybeans."

These are THE most important cash crops for the American farmer, and if they can be as productive, meaning getting an equivalent yield per acre, then there is truly no incentive to grow industrial foods, except for its easier. But, most farmers, want to grow food they can eat, they can be proud of, and won't hurt the land or the people eating it.

Finally, there is money in the organic foods industry. As I wrote in an earlier posting, last year American's spent $20 billion on organic foods. While that isn't close to the overall food spend, that ain't chump change. Also the trends are that people are buying more and more organics.

So, get on the bandwagon, get healthy and buy organic.
