The Importance of Soil Testing Before You Garden

It's that time of year when we all want to break the chains of winter and back out into nature. What many of us don't realize is that there may be danger lurking in our soil. If you live in a home that is older than 40 years old, if you live near a factory, and/or you don't know the land use records of the land before you moved in, it's very important to test your soil for toxic chemicals.

Recently, citizens of Tonawanda, NY found out that their soil was contained with elevated levels of the carcinogen Benzo[a]pyrene, or BaP. This BaP may have been released from the local Coke foundry plant (The Buffalo News, 2014).

So how do you test your soil?

Contact your local cooperative extension office: http://www.csrees.usda.gov/Extension/

Contact your local university's agriculture program to see if they offer soil testing services.

New York City Schools recommend that all schools test their garden soil every two years for heavy metals and nutrient levels. They also give instructions on how to collect the soil for test samples.

The good thing about county extension offices is that not only will they help you with soil testing, they will offer guidance on how to plant the best garden for your type of soil. So remember, test first, then garden.

Cadmium in children's toys

We've often heard of lead in children's toys, but we also need to be concerned about cadmium. Cadmium is a metal that can be found in children's products, including clothing accessories, jewelry, and the paint on the surfaces and linings of toys. Outside of children's products, it can be found in batteries, metal coatings, industrial paints, tobacco smoke, and as a stabilizers in plastics.

Cadmium is used as an alternative to lead. It's cheaper, but it's also toxic. Cadmium exposure has been linked to kidney and bone damage, and delayed brain development in children. Cadmium has also been labelled a "known human carcinogen."  Children are of particular concern because they put toys, jewelry and other products in their mouths.

In 2011, the U.S. Congress, limited the amount of cadmium that can be used in toys and there is a voluntary industrial standard on the amount of cadmium that can be used in jewelry. However, critics claim this is not enough, as some products still contain hazardous levels of cadmium. Six states and the European Union have put Cadmium bans into place for certain products. The states are CA, CT, IL, MD, MN and WA.

Green Chemistry: What is it and why do we need it?

While we may be used to traditional chemistry creating both many of the products we use everyday and the toxins we face everyday, we may not be familiar with green chemistry. According to the EPA, green chemistry "is the design of chemical products and processes that reduce or eliminate the generation of hazardous substances."

Green chemistry is presenting opportunities not only for a cleaner environment, but also for increased business opportunities and savings.  A 2011, Pike Research report stated that by the year 2020, green chemistry will save industry $65.5 billion in liability for social and environmental costs. The same report stated that in terms of market opportunity, green chemistry will represent $98.5 billion in market opportunity by 2020. 

One green chemist is already seizing the opportunity. Chemical engineering professor Richard Wool of the University of Delaware uses environmentally-friendly products like flaxseed, chicken feathers and vegetable oil to make a variety a products, including car parts, tape, shoes and roofing materials. 

Colleges and universities around the world are also now focuses efforts on green chemistry. The American Chemical Society, not to be confused with the toxic lobbying group the American Chemistry Council, even provides research grants for green chemistry. Green chemistry allows for continued progress without continued detriment to public and environmental health.

Toxins in Children's Clothing

It seems like everywhere you look these days there is news that something else is toxic! Recently, Greenpeace came out with a report of toxic chemicals found in children's clothing. Greenpeace Taiwan tested 27 brands of children's clothing ranging from Dior to Disney to Hermes and Versace. They found 16 brands contained at least one toxic chemical. The toxic chemicals discovered were phthalates, nonylphenol ethoxylates (NPE), antimony and perfluorinated compounds (PFCs).

 What's is the danger in these chemicals?

• Phthalates are known endocrine disruptors. Phthalates are linked to birth defects, infertility, breast cancer, liver cancer, obesity, and diabetes.
• NPE are endocrine disrupting chemicals.
• Antimony is a carcinogen and is toxic to the skin, liver, heart and lungs. It can be found in polyester textiles. 
• PFCs are endocrine disruptors, are thought to raise the risk for cancer, and are believed to be linked to the following: thyroid disruption, infertility, developmental delays, liver dysfunction, immunotoxicity, preeclampsia and risk of high cholesterol. PFCs can be found in stain-resistant and water-repellant clothing.

These chemicals can also be found in adult clothing. However, since the release of this report, 19 of the 27 brands and one of the fashion suppliers have promised to try to clean up their act and remove the toxic chemicals from their products.

Dietary Toxins and Eating Well

While I normally focus on toxins in personal care products and the environment, I've decided to take a look at toxins and harmful chemicals in the food we eat. This is a collaborative post with a wonderful blogger, Jessica David of Conveying Awareness with Jessica David.

To begin with, let's short list of some chemicals that we need to avoid in the food we eat.

• Mercury in fish: The dangers of mercury exposure include fatigue, memory problems, mercury poisoning, and dangers to the developing fetus.
• Artificial dyes: These are a color followed by a number, for example, Red 3. These dyes have been linked to behavioral problems in children and cancer.
• Sodium nitrate: Found in processed foods like hot dogs, bacon and sausage, sodium nitrate gives these foods their red tint. Sodium nitrates leads to an increase of nitrosamines in your body, which can lead to cancer. 
• Bisphenol A ( BPA): Often found in the lining of canned foods and beverages. It is estrogenic and can also leach from plastic. BPA has been linked to diabetes and heart disease. 
• Polychlorinated biphenols (PCBs): These are industrial coolants that can be found in farm-raised fish and are known endocrine disruptors and carcinogens. 
• Dioxins: Dioxins are contaminants formed during combustion and industrial processes. For example, trash burning, forest fires, incineration, herbicide manufacturing, and paper pulp bleaching. Dioxins can also be found in farm-raised fish and in the fatty tissues of animals that have been exposed to dioxins. The risks of dioxin exposure include, reproductive & developmental problems, an increased risk of diabetes and heart disease, and cancer. 
• Hydrogenated oils: Oils are long, often branched chains of carbon and hydrogen that are liquid are room temperature. The branches are caused when there are carbon to carbon double bonds. Scientists can go into the lab and add hydrogen atoms to these double bonds to break them and make the molecule more stable. This is a hydrogenated oil. They are used to increase the shelf life of food products, but have been linked to diabetes and heart disease.
• Artificial sweeteners: Aspartame is probably the most famous artificial sweetener. It has been linked to headaches, dizziness and neuronal damage. Recently, another artificial sweetener, Splenda (sucralose) was linked to the release of cancer-causing chemicals when cooked & baked.
• GMOs: GMOs are genetically modified organisms. They are created when scientists take the genes from organism/species A and put them into unrelated organism/species B. We were told that GMOs would help alleviate the problem of world hunger, but instead, GMOs have largely been used to increase the consumption of pesticides (The Link Between GMOs and Pesticides). Studies on the safety of GMOs have largely come from the companies that produce GMOs, who have a vested interest in the outcome of those studies. While more independent scientific studies are needed on the safety of GMOs on humans, experiments from farmers show that animals prefer non-GMO food. One scientific study on rats, showed lifetime exposure to Roundup Ready GM corn lead to tumors, multiple organ damage and death. 
• Pesticides: Conventional farming relies heavily on pesticides. Pesticides have been linked to endocrine disruption, infertility, neurological damage and cancer. The most widely used pesticide, atrazine, has been extensively studied by Dr. Tyrone Hayes of UC Berkeley. He used to work for the company that made the pesticide, Syngenta, but when he tried to publish a paper on the negative effects of the product, they stopped him. Syngenta has been trying to stop him ever since. His website can be found here. Unfortunately, even organic foods are exposed to some pesticides through rain, runoff and the water table, though to a lesser extent than conventional produce.

Now let's transition into how you can improve your diet to become your best you.

One of my passions is to share the benefits of eating the [real] rainbow daily and it's found in fruits and vegetables. I wasn't always like this though. It only occurred to me about 5 years ago the importance of eating more of nature's best so that I could heal some conditions that had plagued me for years. Though I have always been thin, I wasn't always healthy and I didn't know any better and guess what? I didn't care much about longevity in my 20s. It wasn't until I became a mom at age 31 that I decided to make some changes! It took another new mom to pull me aside and share with me how I could eat more fruits and vegetables and that it could be the first step in the right direction for reversing some damage done through nutrient poor food choices that I had made for many years. 

Fast forward a few years, I became a certified health coach. The seed to link arms with others in their wellness journeys was planted months after that talk with my friend. Learn more about my story here. So here I am encouraging you to strive for 5. Eat five different fruits and 5 different vegetables daily. Here are some tools to help you meet that goal. 
  
1) Download my free eGuide.  
2) Learn more about Traffic Light Eating from a L.E.A.N. perspective. 
3) Follow me on Pinterest. These boards are helpful: + Eating the Real Rainbow + Recipes Using Veggies + My recipes  
4) Join a CSA (farm-share co-op). For a listing in your area, visit Local Harvest. 
5) If it's right for you, take one of my L.E.A.N. Start online classes. 

In session three, we talk about ways to eat more of nature's best - fruits and vegetables! Info. 

In tip 2, it mentions the L.E.A.N. perspective. This is the 4 pillars of health: Lifestyle, Exercise, Attitude, and Nutrition and no matter the way you slice it (different words to describe the same concepts), we need all 4 components for our journey to wellness. World-renown pediatrician and author of nearly 40 books, Dr. Bill Sears (of the Sears Wellness Institute) teaches us that the most basic foundation of understanding nutrition is through the colors of a stoplight. Today's lesson is on the green light. The other two colors are summarized in tip two.

Green light foods are fruits and vegetables found closest to nature. If you're concerned about pesticides, other contaminants, and GMOs, purchase them organic or know your supplier. I teach that eating a variety of fruits and vegetables is key to wellness and the benefits outweigh the risks. Over time, as your pockets adjust, you will find that eating produce without *most contamination may serve you better and it will support small local farmers and their families. Knowing your supplier is key because you can support local farmers and their families that cannot afford the organic label. This also applies to getting whole food nutrients in a capsule. If the product doesn't carry the USDA Organic seal, you may also look for NSF International's seal - this means that what the product claims to have or not have in their product is the truth via NSFs third-party non-affiliated testing and certification. * Even USDA Organic foods have some contaminants. See this link for more info. 

I live in a food desert. The options for fresh, sustainable produce free of contaminants are low. There are no farmers' markets in my area so it is difficult for me to find a good variety of produce locally. I shop about twice a week to two or three stores to find the best quality of produce. It's important for me to eat a variety of produce and for specific crops, I almost always buy organic when I can (see EWG Dirty Dozen for more info, link is below). I'm thankful that there is a farm-share co-op drop off in my city. I am a subscriber to Abundant Harvest Organics and eventually, I hope to grow my own soon with a Tower Garden. 

If you want more information on which fruits and vegetables have the highest levels of contaminants, visit EWGs: The Dirty Dozen. If you'd like to know how many and what kinds of contaminants are on your produce, check out What's On My Food.  Choose, eat, and live well! =)
