Why is range-fed and grass-fed meat and poultry better?
The natural behavior of cows, chickens turkeys, pigs, and other animals commonly eaten for food in the United States is to live outdoors and to consume food that is part of the natural habitat. For example, in the case of ruminant animals like cows, there is a long history of development in which the digestive system of the cow has adapted to foraging and consumption of plants often referred to as "forages." These plants include many grasses and legumes.
When cows are fed in a non-natural way, digestive tract problems can develop, and medications may be needed to offset problems caused by the cows' non-natural diet. For example, when being raised to provide non-organic beef, it is not unusual for a cow to be fed more than 10 pounds of corn per day. Since the cow's digestive system is poorly matched to this large volume of grain in the daily diet, it is placed at risk for certain problems including bursting of the stomach from excessive amounts of gas that can be produced by fermentation of grain. In the case of non-organic beef, medications that prevent gas formation (like poloxalene) may be given to cows on a preventive basis as part of their standard diet to prevent this gas formation. However, the routine administration of a medication like poloxalene cannot be carried out in the raising of certified organic beef. Research studies have made it clear that cows remain healthier when they are fed and raised in a natural way. Healthier cows also mean healthier meat for all individuals who include meat in their diet.
One great benefit of grass feeding is the increased presence of omega-3 fatty acids in beef provided by grass-fed cattle. I've seen two studies on Australian beef that clearly document this trend, which stems from the natural presence of alpha-linolenic acid (also known as ALA, the omega-3 fatty acid that serves as the building block for all other omega-3 fats) in pasture grasses and legumes. While more complicated omega-3 fats like EPA (eicosapentaenoic acid) and DHA (docosahexaenoic acid) are not present in pasture crops, these critical omega-3 fats are produced in the cow's body from the ALA present in the pasture plants and you can receive substantial amounts of EPA and DHA from pasture-fed beef along with its ALA. These amounts are still very low, however, in comparison with the far greater amount of EPA and DHA provided by an equivalent amount of an omega-3-containing fish like salmon. The amount of ALA in grass-fed beef is also very much lower than the amount of ALA provided by plant foods like flaxseeds and walnuts, which are rich in this omega-3 fatty acid.
I want to point out that the purchase of certified organic beef, poultry, and other meats does not guarantee range-feeding. Unfortunately, the livestock living conditions spelled out in the National Organics Program only includes "access to the outdoors" and "access to pasture" and does not specify any required period of time for natural outdoor living. Nor does it require any amount of foraging crops in the diet. For this reason, you'll need to look for the terms "range-fed" or "grass-fed" on the label in addition to the organic certification. Organic meat that is not labeled either "range-fed" or "grass-fed" is still a very good option for you in the market, but if organic combined with range-fed or grass-fed is available, I encourage you to consider that combination as your best option.

Trapped in Traditional Thought by Scott McKain

I agree with the majority of what this article says...
Ditch the Climate Change Debate by Ron Jones
A recent editorial cartoon that I ran across cleverly expressed a great deal of my own thoughts around the climate change debate. The cartoonist (Joel Pett, Lexington Herald-Leader) depicts an obviously unconvinced audience member at a presentation where benefits of clean energy are being displayed on the stage screen. The attendee is shown demanding an answer to a question similar to the following:
"What if it turns out that climate change is all a big hoax and we create a better world for nothing?"
The presenter he is questioning has a list of goals on the screen including:
• Energy Independence
• Preserve Rainforests
• Sustainability
• Green Jobs
• Livable Cities
• Renewables
• Clean Water, Air
• Healthy Children
In a single frame, and with surgical irony, the cartoonist has masterfully steered us to the question I have been asking myself and others for a long time, which is essentially, why are we not able to shift the dialog onto a productive level that leaves the polarization and bickering behind so we can just get started on the enormous task of cleaning up the mess we've been helping to make?
We don't have to reach some final, indisputable conclusion on the "climate" debate to know that there are plenty of good reasons to take steps to replace 18th and 19th century technologies and the polluting energy sources that have been fueling them.
The answer must reside somewhere deep in human nature. There seems to be an irresistible force of passion that makes us dig in our heels and refuse to budge when we feel strongly about something. In this case, it doesn't really matter if we're talking about those who view "climate change" or "global warming," as some prefer to refer to it, as the great challenge of our time or those who are absolutely convinced that it is the greatest hoax ever perpetrated on mankind.
It seems that those who have taken a passionate stand either way are prepared to fight over this for as long as takes, and unfortunately, the fact that people in both camps seem determined to drive to an "all or nothing" resolution keeps getting in the way of potential progress on the things we could agree on.
Even the most hardcore climate skeptics don't try to make their case by denying or stating opposition to goals like those listed by the cartoonist, they just refuse to go there. At the same time, their counterparts, who are every bit as passionate in their insistence that mankind's activities are at the center of all the problems in the world, often appear to be pushing for absolute and immediate solutions with little or no willingness to explore common ground. The net result is an ongoing bitter conflict that is often stalled by distractions leaving those of us in the middle stranded and feeling like we can't do anything meaningful to influence the outcome.
I am personally convinced that we are indeed witnessing measurable levels of global climate change. I only make this statement based on personal observation and certainly not because I believe the reports of governments, including our own, or the findings of scientists I have never met. I have reached my conclusion because I have observed certain evidence with my own eyes. I've visited glaciers from Alaska to New Zealand that are receding at unprecedented and alarming rates. I have flown over millions of acres of America's western forests and seen the beetle kill that is resulting from milder winter temperatures to the detriment of not only the trees, but also virtually every species in that ecosystem.
What I have no way of verifying on my own is how much of this shift is attributable to the activities of the human species. I seriously doubt that it is the primary factor. Both sides of this debate agree that the scale and complexity of the Earth's atmosphere and its global climate have seen numerous dramatic shifts to one extreme or the other over time.
What I do know is that I have seen the contrast between the air in Beijing and other cities in the Northern Hemisphere with that of still pristine regions of the South Pacific. The calamity is there for anyone who is interested to see. I have also fished a variety of streams, rivers, lakes, and reservoirs throughout North America where the fish populations face collapse from human-caused pollution and where signs are posted to warn against consuming the fish that are there.
Put simply, we have used our one and only planetary home and all of its natural systems as a garbage dump of one kind or another for practically all of recorded human history. Sadly, the situation has only worsened over the last few centuries as we made industrial "advances" and as human population has swelled. We have treated it like a trash can and no matter how big the can is, it can only hold so much. We are reaching that point and before it's too late we need to revise our practices. It's time to clean up our act and "create a better world"—whether global warming is a hoax or not.

What type of cookware should I use for microwave cooking?
We are highly concerned about migration of plastics from containers into food. Therefore, we would suggest avoiding its use in cooking situations including in the microwave. (For the same reasons we would avoid using "boil-in-a-bag" type vegetables.)

New study finds synthetic musks in umbilical cord blood.
Artificial musks commonly added to fragrances and personal care products can be absorbed through skin or inhaled, and concentrate and persist in our bodies - so our many small exposures can add up fast. Synthetic musks have also been found in human breast milk and fatty tissues, and are ubiquitous in wastewater and rivers.
The cosmetics industry and other industries that use "fragrance" in their products use a whopping 9,000 tons of synthetic musk annually, despite the fact that little is known about the safety of these chemicals. Unfortunately, preliminary research raises concerns: musks may disrupt hormones and are toxic to aquatic life.
Because of a loophole in labeling law, the ingredients in "fragrance" are considered trade secrets, so companies don't have to tell us what's in scents - often dozens or even hundreds of synthetic chemical compounds like synthetic musks and other ingredients linked to harm.
Biomonitoring studies like this one make clear that chemicals - many of which have never been tested for long-term safety or are known to be harmful - used in everyday products are ending up in our bodies and in our ecosystem. At the same time, cancer, infertility, and behavioral and developmental illnesses linked to many of these chemicals of concern are on the rise.
As consumers and citizens, we can fight the fragrance loophole. Here are three ways you can make a difference:
Contact the manufacturer of a cosmetic product in your bathroom that lists "fragrance," "perfume" or "musk" on the ingredient label, and ask the maker to use non-toxic ingredients and fully disclose all ingredients on products labels. Click here for contact info, talking points and a short response form so you can let us how your conversation went!
This holiday season, choose gifts free of synthetic fragrance. Consult the list of companies that have signed the Compact for Safe Cosmetics, and use EWG's Skin Deep database to run an "advanced search" of products without synthetic fragrance.
