Organic Produce Reduces Exposure to Pesticides, Research Confirms
Consumers can markedly reduce their intake of pesticide residues and their exposure to antibiotic-resistant bacteria by choosing organic produce and meat, according to researchers at Stanford University who reviewed a massive body of scientific studies on the much-debated issue.
The Stanford team analyzed more than 230 field studies and 17 human studies conducted in the U.S. and Europe to compare pesticide residues, antibiotic resistance and vitamin and nutrient levels in organic and conventionally produced foods. The study, published Sept. 3, is available online at the website of The Annals of Internal Medicine.
“The study confirms the message that Environmental Working Group (EWG) and scores of public health experts have been sending for years, that consumers who eat organic fruits and vegetables can significantly reduce pesticide concentrations in their bodies,” said Sonya Lunder, senior analyst at EWG. “This is a particularly important finding for expectant mothers and kids, because the risks of dietary exposures to synthetic pesticides, especially organophosphate and pyrethroid insecticides, are greatest during pregnancy and childhood, when the brain and nervous system are most vulnerable. These are two groups that should really avoid eating foods with high levels of pesticide residues.”
Based on its review of the available research, the Stanford team also concluded that conventionally raised meat harbors more antibiotic resistant bacteria. It found that consumers of non-organic chicken or pork are 33 percent more likely to ingest three or more strains of antibiotic-resistant bacteria than those who eat organic meat.
“What jumped out at us in this study is that conventionally-raised meat treated heavily with antibiotics is much more likely to carry drug-resistant bacteria than meat produced on organic farms,” said Kari Hamerschlag, senior analyst at EWG, who focuses on organic and conventional agriculture. “Antibiotics, which are banned in organic production, promote the development of resistant super-bugs that are a serious risk to human health.”
The researchers did not find “significant” or “robust” differences in nutritional content between organic and conventional foods. But Charles Benbrook, a professor of agriculture at Washington State University and former chief scientist at The Organic Center who reviewed the Stanford study and most of the underlying literature, had this to say in response:
This study draws a markedly different conclusion than I do about the nutritional benefits of organic crops. Several well-designed U.S. studies show that organic crops have higher concentrations of antioxidants and vitamins than conventional crops. For crops like apples, strawberries, grapes, tomatoes, milk, carrots and grains organic produce has 10 to 30 percent higher levels of several nutrients, including vitamin C, antioxidants and phenolic acids in most studies.
The Stanford study also contradicts the findings of what many consider the most definitive analysis in the scientific literature of the nutrient content of organic versus conventional food.
In that 2011 study, a team led by Dr. Kirsten Brandt of the Human Nutrition Research Center of Newcastle University in the United Kingdom analyzed most of the same research and concluded that organic crops had approximately 12 to 16 percent more nutrients than conventional crops.
EWG noted that the Stanford study also did not directly address the important environmental and public health benefits that result from reduced pesticide and antibiotic use. Synthetic pesticides can kill insect pollinators, harm wildlife and farmworkers and often end up in the air and water. Tests conducted in 2011 by the U.S. Geological Survey found that glyphosate (commonly sold as Roundup), one of the most widely used herbicides, was a ubiquitous contaminant in air, water and rainfall in two Midwest states.
“Organic produce and meat products live up to their promise,” said Ken Cook, EWG president. “Consumers selecting organic produce ingest fewer pesticides. They also eat meats that harbor fewer deadly bacteria. While you still need to take responsibility for eating a varied and healthy diet, you can rest assured that organic food provides a healthier choice for people and the planet.”
While the Stanford study briefly mentioned previous research on the effects of organic foods on children’s health, it did not focus on the growing body of studies published in the last decade that have demonstrated children’s higher sensitivity to the effects of neurotoxic pesticides. Last year, Cook, along with several of the world’s most respected authorities in environmental health, sent a letter to the Obama Administration requesting that the federal government expand the testing it conducts on crop chemical residues in foods “to give Americans a full accounting of risks faced by children who consume pesticides on produce.”
“Studies that have come out in the last two years have linked exposures to organophosphate pesticides with increased risks of ADHD and lower IQ in children and to low birth weight and early gestation among newborns,” said Cook. “The authors of this study, for whatever reason, decided not to focus on this new and troubling research showing that a diet of food high in certain pesticides could pose such serious and lasting health impacts in children. That’s a glaring omission, in my opinion.”

In the midst of a pandemic, sales of cleaning products have skyrocketed, and many feel a need to clean more often. Knowing what to look for when purchasing cleaning supplies can help prevent unwanted and dangerous toxics from entering your home.
1. Fragrance – Avoid It<p>One of the fastest ways to narrow down your product options is immediately eliminating any product that promotes a fragrance, or parfum. That scent of "fresh breeze" or lemon might initially smell good, but the fragrance does not last. What does last? The concoction of various undisclosed and unregulated chemicals that created that fragrance.</p><p>Many fragrances contain phthalates, which are linked to many health risks including reproductive problems and cancer.</p>
2. With Bleach? Do Without<p>Going scent-free should have narrowed down your options substantially – now, check the front of the remaining packaging. Any that include ammonia or chlorine bleach ought to go, as these substances are irritating and corrosive to your body. While bleach is commonly known as a powerful disinfectant, there are safer alternatives that you can use in your home, such as sodium borate or hydrogen peroxide.</p><p>While you're at it, check if there are any warnings on the label – "flammable," "use in ventilated area," etc. – if the product is hazardous, that's a red flag and should be avoided.</p>
3. Check the Back Label<p>Flip to the back of the remaining contenders and check out that ingredient list. Less is more, here. Opt for a shorter ingredient list with words you recognize and/or can pronounce.</p><p>You may notice many products do not have ingredient lists – while this doesn't necessarily mean they contain toxic ingredients, transparency is key. Feel free to look up a list online, or stick to products that are open about their ingredients.</p>
4. Ingredients to Avoid<p>We already mentioned that cleaners containing fragrance or parfum, and bleach or ammonia should be avoided, but there are other ingredients to look out for as well.</p><ul><li>Quaternary ammonium "quats" – lung irritants that contribute to asthma and other breathing problems. Also linger on surfaces long after they've been cleaned.</li><li>Parabens – Known hormone disruptor; can contribute to ailments such as cancer</li><li>Triclosan – triclosan and other antibacterial chemicals are registered with the EPA as pesticides. Triclosan is a known hormone disruptor and can also impact your immune system.</li><li>Formaldehyde – Causes irritation of eyes, nose, and throat; studies suggest formaldehyde exposure is linked with certain varieties of cancer. Can be found in products or become a byproduct of chemical reactions in the air.</li></ul>
Cleaning Products and Toxics: The Bottom Line<p>Do your research. There are many cleaning products available, but taking these steps will drastically reduce your options and help keep your home toxic-free. Protecting your home from bacteria and viruses is important, but make sure you do so in a way that doesn't introduce other health risks into the home.</p><p><em>Reposted with permission from </em><em><a href="https://www.ehn.org/how-to-shop-for-cleaning-products-while-avoiding-toxics-2648130273.html" target="_blank">Environmental Health News</a>. </em><a href="https://www.ecowatch.com/r/entryeditor/2649054624#/" target="_self"></a></p>

Returning the ‘Three Sisters’ – Corn, Beans and Squash – to Native American Farms Nourishes People, Land and Cultures
By Christina Gish Hill
Historians know that turkey and corn were part of the first Thanksgiving, when Wampanoag peoples shared a harvest meal with the pilgrims of Plymouth plantation in Massachusetts. And traditional Native American farming practices tell us that squash and beans likely were part of that 1621 dinner too.
Abundant Harvests<p>Historically, Native people throughout the Americas bred indigenous plant varieties specific to the growing conditions of their homelands. They selected seeds for many different traits, such as <a href="https://emergencemagazine.org/story/corn-tastes-better/" target="_blank" rel="noopener noreferrer">flavor, texture and color</a>.</p><p>Native growers knew that planting corn, beans, squash and sunflowers together produced mutual benefits. Corn stalks created a trellis for beans to climb, and beans' twining vines secured the corn in high winds. They also certainly observed that corn and bean plants growing together tended to be healthier than when raised separately. Today we know the reason: Bacteria living on bean plant roots pull nitrogen – an essential plant nutrient – from the air and <a href="http://www.tilthalliance.org/learn/resources-1/almanac/october/octobermngg" target="_blank" rel="noopener noreferrer">convert it to a form that both beans and corn can use</a>.</p><p>Squash plants contributed by shading the ground with their broad leaves, preventing weeds from growing and retaining water in the soil. Heritage squash varieties also had spines that discouraged deer and raccoons from visiting the garden for a snack. And sunflowers planted around the edges of the garden created a natural fence, protecting other plants from wind and animals and attracting pollinators.</p><p>Interplanting these agricultural sisters produced bountiful harvests that sustained large Native communities and <a href="http://dx.doi.org/10.1353/eam.2015.0016" target="_blank">spurred fruitful trade economies</a>. The first Europeans who reached the Americas were shocked at the abundant food crops they found. My research is exploring how, 200 years ago, Native American agriculturalists around the Great Lakes and along the Missouri and Red rivers fed fur traders with their diverse vegetable products.</p>
Displaced From the Land<p>As Euro-Americans settled permanently on the most fertile North American lands and acquired seeds that Native growers had carefully bred, they imposed policies that <a href="https://doi.org/10.1086/ahr/87.2.550" target="_blank">made Native farming practices impossible</a>. In 1830 President Andrew Jackson signed the <a href="https://guides.loc.gov/indian-removal-act" target="_blank">Indian Removal Act</a>, which made it official U.S. policy to force Native peoples from their home locations, pushing them onto subpar lands.</p><p>On reservations, U.S. government officials discouraged Native women from cultivating anything larger than small garden plots and pressured Native men to practice Euro-American style monoculture. Allotment policies assigned small plots to nuclear families, further limiting Native Americans' access to land and preventing them from using communal farming practices.</p><p>Native children were forced to attend boarding schools, where they had no opportunity to <a href="https://doi.org/10.5749/jamerindieduc.57.1.0145" target="_blank">learn Native agriculture techniques or preservation and preparation of Indigenous foods</a>. Instead they were forced to eat Western foods, turning their palates away from their traditional preferences. Taken together, these policies <a href="https://kansaspress.ku.edu/978-0-7006-0802-7.html" target="_blank" rel="noopener noreferrer">almost entirely eradicated three sisters agriculture</a> from Native communities in the Midwest by the 1930s.</p>
Reviving Native Agriculture<p>Today Native people all over the U.S. are working diligently to <a href="https://www.oupress.com/books/15107980/indigenous-food-sovereignty-in-the-united-sta" target="_blank" rel="noopener noreferrer">reclaim Indigenous varieties of corn, beans, squash, sunflowers and other crops</a>. This effort is important for many reasons.</p><p>Improving Native people's access to healthy, culturally appropriate foods will help lower rates of <a href="https://www.cdc.gov/vitalsigns/aian-diabetes/index.html" target="_blank">diabetes</a> and <a href="https://www.apa.org/pi/oema/resources/ethnicity-health/native-american/obesity" target="_blank">obesity</a>, which affect Native Americans at disproportionately high rates. Sharing traditional knowledge about agriculture is a way for elders to pass cultural information along to younger generations. Indigenous growing techniques also protect the lands that Native nations now inhabit, and can potentially benefit the wider ecosystems around them.</p>
