Most people don't realize how quickly many pesticide levels decrease in our bodies after switching to eating organic foods. Studies find significantly lower levels in a few weeks for many pesticides, but in the case of glyphosate - it's within days!

This is significant because each year more health harms are being linked with glyphosate exposure, such as cancer, shorter pregnancies, disruption of the gut microbiome, cancer, kidney toxicity, and liver inflammation.

Glyphosate (found in Roundup) is the most widely used herbicide (weed killer) in the world. Millions of pounds are used each year in the US, typically for weed control in outdoor areas, as well as on genetically modified crops (e.g., corn, soybeans, canola), and frequently right before harvest on conventional crops (e.g., wheat, oats, barley).

Food is the primary source of glyphosate exposure. Many non-organic foods (especially wheat, oats, barley, soybeans, legumes) contain glyphosate residues. Glyphosate is even found in breakfast cereals Organic food does not contain glyphosate  - it's use is not allowed in organic food production.

Researchers first tested the urine of people eating a totally non-organic diet, and then when eating an all organic diet. There was a 70% reduction in glyphosate and its metabolite AMPA within 3 days. Children had significantly higher levels of glyphosate and AMPA than adults in their urine in both the non-organic and organic phases of the study.

Bottom line: Eat as many organic foods as possible. And don't use glyphosate (Roundup) on your property.

From Environmental Health News: Organic diets quickly reduce the amount of glyphosate in people’s bodies

Eating an organic diet rapidly and significantly reduces exposure to glyphosate—the world's most widely-used weed killer, which has been linked to cancer, hormone disruption and other harmful impacts, according to a new study. ...continue reading "An Organic Diet Rapidly Lowers Glyphosate Levels In the Body"

Published on Leave a comment on A Commonly Used Pesticide, Children, and Liver Inflammation

Millions of pounds of pesticides are used each year in the US for all sorts of reasons - crops, lawns, inside homes, aerial spraying, etc. But what many people don't realize is that the pesticides get into us and they have harmful effects on us. Pesticides can be absorbed through the skin, ingested (from food and water), or inhaled.

One pesticide that we're being exposed to in increasingly larger amounts each year is glyphosate, commonly known as Roundup. Food is the main way glyphosate gets into us, and so we are exposed to it almost daily. And yes, it is in almost all of us. It's used for weed control in outdoor areas, as well as on genetically modified crops (e.g., corn, soybeans), and frequently right before harvest on conventional crops (e.g., wheat, oats, barley).

Recently researchers at the UC Berkeley School of Public Health found that glyphosate exposure in childhood is linked to liver inflammation, fatty liver disease, and metabolic syndrome in early adulthood. These conditions can lead to diabetes, heart disease, and strokes.

There is increasing evidence of harms from glyphosate (e.g., shorter pregnancies, disruption of the gut microbiome, cancer, kidney toxicity).

What to do to lower exposure to glyphosate? Eat organic foods whenever possible. Levels in the body will go down within a week. Organic farmers and food producers are not allowed to use glyphosate.

From Environmental Health News: Kids’ glyphosate exposure linked to liver disease and metabolic syndrome

Over the last decade, Dr. Charles Limbach noticed something strange in his family medicine practice in East Salinas, California.

Kids between 5 and 15 years old showed elevated levels of liver enzymes, a sign of liver inflammation. Limbach ordered a panel of medical tests on each patient and repeatedly saw the same result: fatty liver disease. ...continue reading "A Commonly Used Pesticide, Children, and Liver Inflammation"

Published on Leave a comment on The Pesticide Industry Is Fighting All Local Government Attempts To Restrict Pesticide Use

The pesticide industry is lobbying tooth and nail to take away the right of towns and states to pass pesticide laws that protect people. And to do away with laws already passed in about 200 communities in the U.S. The pesticide industry doesn't like that these laws are stricter than federal laws (which are pretty lax).

It has been documented over and over that the chemical industry has basically corrupted the EPA with chemical industry money, with the end result that many dangerous chemicals (including pesticides) are allowed to be used freely in this country. This includes pesticides that are banned in other countries (because they are so harmful).

The House of Representatives will try to adopt a bill in 2023 that will prohibit local governments from adopting pesticide laws that are more protective than federal rules.  This is H.R. 7266, which was introduced in the House of Representatives in March 29, 2022. In summary:

This bill amends the Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA) to prohibit local regulations relating to the sale, distribution, labeling, application, or use of any pesticide or device subject to regulation by a state or the Environmental Protection Agency under FIFRA.

Why is this is a big deal? This is an attack on local governments and on the nearly 200 communities across the United States that have passed their own policies to restrict the use of toxic pesticides. Communities need to keep the right to restrict pesticides linked to cancer and other health problems, that contaminate water, that result in the decline of pollinators, and to protect the health of residents and local ecosystems.

A good example is a town deciding that it would encourage pollinators (bees!) by banning neonicotinoid pesticides within the town. (Yes, there are alternate pesticides one can use.) However, such a move would not be allowed under the new bill because they are not banned at the federal level. It doesn't matter that the community totally supports such a ban (perhaps bee-keeping and honey are a main industry in the town).

Note that many pesticides targeted by local city residents, including neonicotinoids, glyphosate, and atrazine, have been banned or restricted in other countries due to health or environmental concerns.

 An informative write-up of this issue from Beyond Pesticides: In New Congress, Republican-Led Legislation Would Prevent Local Governments from Protecting Health and Safety

As the new 118th Congress convenes on January 3, 2023, one of the key issues on the agenda led by Republicans in the U.S. House of Representatives is preemption of local authority to restrict pesticide use—undercutting the local democratic process to protect public health and safety. In the 117th Congress, H.R. 7266 was introduced to prohibit local governments from adopting pesticide laws that are more protective than federal rules. ...continue reading "The Pesticide Industry Is Fighting All Local Government Attempts To Restrict Pesticide Use"

Published on Leave a comment on The EPA Is Still Approving Pesticides Linked To Breast Cancer

The EPA has many serious problems, from protecting corporations and not consumers, to ignoring studies that find health problems with products or chemicals. Dr. Jennifer Liss Ohayon, a research scientist at Silent Spring Institute and Northeastern University, pointed out in a recent article that the EPA keeps approving pesticides linked to breast cancer.

These pesticides act as endocrine disruptors on the breast, with effects occurring at low doses. Many are commonly used (e.g., malathion, atrazine), which means women are exposed to in food, water, the workplace, and at home (yes - home, garden, and lawn chemicals!).

Why be concerned? Young women are experiencing earlier breast development, difficulty in breastfeeding, and increasing rates of breast cancer. Many studies link this in women (and in animals) with chemical exposures, especially endocrine disrupting chemicals (this is because they screw with hormones, and so have an effect on breast development and breast tissue).

But... the EPA is dismissing or ignoring relevant studies and pooh poohing the idea that chemicals can have harmful endocrine disrupting effects. Effects on the breast (mammary gland) are NOT required to be part of the EPA's chemical risk assessment (which determines whether a pesticide will be approved). The studies the EPA relies on are almost all financed by the manufacturers (hmmm...of course they'll say the pesticide is safe).

Note that the European Union bans many of the worrisome pesticides - they are not ignoring the science, and in doing so protect people.

From a piece by Dr Jennifer Liss Ohayon at Environmental Health News (EHN): Why is the EPA still exposing women to pesticides linked to breast cancer?

This fall marks the 60th anniversary of writer and scientist Rachel Carson’s 1962 book “Silent Spring.” The book was seminal in that it sparked the modern environmental movement, a U.S. ban of DDT, and the founding of the Environmental Protection Agency (EPA). However, despite decades passing since Carson first warned us about the dangers of pesticides, EPA continues to approve pesticides linked to breast cancer. ...continue reading "The EPA Is Still Approving Pesticides Linked To Breast Cancer"

Published on Leave a comment on Sperm Counts Are Still Dropping Throughout the World
Human male sperm Credit: Wikipedia

Oh no... Back in 2017 a large study found that male sperm counts had dropped over 50% since the 1970s in North America, Europe, and Australia. Declining every year, year after year, for over 40 years. This has serious implications for fertility - if sperm counts drop too low, it's very difficult to conceive a baby.

Now those same researchers have published data from 53 countries showing that the sperm count decline is also occurring in Asia, South America, and Africa. And that the decline in male sperm counts is actually accelerating in North America and Europe. Yikes!

Note that this is in men who weren't being screened for fertility problems issues. In other words, random healthy men. Some had already fathered a baby.

Globally, the decline was about 1.16% per year from 1973 to 2018 (resulting in a 52% decline). When the researchers reexamined the data and looked at many more studies, they realized that since 2000 the decline accelerated at 2.64% per year.

Average global sperm concentration was 49 million per milliliter of semen in 2018. The researcher Dr. Swan pointed out that when sperm count drops below roughly 45 million per milliliter, the ability to cause a pregnancy begins to plummet dramatically, and at 40 million and lower the chances of conception are very low without reproductive assistance (e.g., IVF).

Interestingly, sperm counts are not just a male fertility issue, but also an indicator of men's health. Low levels of sperm are associated with increased risk of chronic disease, testicular cancer, and a shorter lifespan. With a decline in sperm numbers there is also a decline in testosterone and male genital anomalies - thus a decline in male reproductive health.

Why is this happening? Several possibilities are probably contributing: mainly lifestyle and also all the chemicals and plastics in our lives (environmental chemical exposure). Endocrine disruptors, phthalates, pesticides! Yes, they are all around us - in the air, the water, consumer products, and our bodies.

Some examples: pesticides, flame retardants, stain and water resistant products. Plastics leach and outgas and we get them into us various ways (skin, inhale them, ingest them in our foods and water). List of ways to reduce exposure to harmful chemicals.

THINGS YOU CAN DO TO IMPROVE SPERM COUNT AND HEALTH:

Lifestyle: Don't smoke. Don't drink or drink very little. Don't do drugs. Don't sit in hot tubs or saunas. Get exercise or physical activity. Eat a diet rich in fruits, vegetables, whole grains, legumes, seeds, nuts. Avoid canned foods, minimize fast food take-out. Eat as much organic as possible. Lose weight, if needed.

Chemical exposure: We can't totally avoid all the chemicals, but we can minimize our exposure. For starters, stop using non-stick cookware, avoid pesticides in the home and yard (look for nontoxic alternatives and view weeds as wildflowers), don't use dryer sheets, buy unscented products (and avoid fragrances). List of ways to reduce exposure to harmful chemicals.

From Science Daily: Significant decline in sperm counts globally, including Latin America, Asia and Africa, follow-up study shows

An international team led by Professor Hagai Levine of Hebrew University of Jerusalem's Hadassah Braun School of Public Health, with Prof. Shanna Swan at the Icahn School of Medicine, Mount Sinai, New York, along with researchers in Denmark, Brazil, Spain, Israel and the USA, published the first meta-analysis to demonstrate declining sperm counts among men from South and Central America, Asia and Africa. ...continue reading "Sperm Counts Are Still Dropping Throughout the World"

Published on Leave a comment on Almost All Pregnant Women Have This Pesticide In Their Body

Pesticides causing health problems are appearing in study after study. A recent study found that higher glyphosate levels in pregnant women is associated with lower birthweight in the babies and higher risk of admission to neonatal intensive care units.

Studies find that almost all pregnant women have detectable levels of glyphosate in their bodies - which of course reaches the fetus. In this study by Univ. of Indiana researchers it was detected in 99% of the women during the first trimester! Higher levels resulted in reduced fetal growth. This is very concerning.

Glyphosate is found in the popular herbicide (weed-killer) Roundup. The use of glyphosate has increased substantially with genetically modified crops (e.g., Roundup resistant crops such as corn and soybeans) and with its preharvest use in conventionally raised crops (preharvest guide). It's found on many regular oats, wheat, soybeans, canola, lentils flax, etc.

This is why with each new study higher levels are found in people. It's in our food.

What else is glyphosate doing to us? It has been linked to a number of human health effects, such as cancer, endocrine (hormone) disruption, liver and kidney damage, preterm birth, and even having a negative effect on our gut microbiome - by killing off certain important species of gut microbes. There is much we still don't know about chronic exposure to low levels of the pesticide.

By the way, the United States FDA allows higher levels of glyphosate residues in food and humans than other countries, including European countries. Of course this is due to the pesticide industry lobbying the FDA real hard, political interference, and then think of all those cushy pesticide industry jobs government workers eventually get as a reward. (Yes, it's revolving door from the government to industry jobs...)

Organic farmers are not allowed to use glyphosate. So if you want to avoid the pesticide - eat as many organically grown foods as possible.

From Science Daily: High exposure to glyphosate in pregnancy could cause lower birth weights in babies

Indiana University School of Medicine researchers are learning more about the effects of herbicide exposure during pregnancy, finding glyphosate in 99 percent of the pregnant women they observed in the Midwest. In the study, published recently in Environmental Health, higher glyphosate levels were associated with lower birth weight and may also lead to higher neonatal intensive care unit admission risk. ...continue reading "Almost All Pregnant Women Have This Pesticide In Their Body"

Published on Leave a comment on Leave Your Shoes At The Door

It has been known for years that wearing your shoes indoors means that everything that is on the ground outdoors will be tracked into the home. Pesticides, heavy metals, lead, animal feces, and everything else out there.

Babies crawling around the floor (and also putting things into the mouth) get an extra heavy dose of "contaminants" that were tracked in. We all absorb contaminants through our skin, ingest (the mouth), or breathe them in.

All these contaminants become part of our indoor air quality. Our indoor air is not just the outside contaminants that made their way in, but there is also shedding of skin and cloth fibers from us and pets, as well as outgassing and breakdown (the dust) of whatever is in the home. We can't get rid of all contaminants, but we can really lower our exposure to them by not wearing our shoes indoors.

Bottom line: Take your shoes off at the door.

A nice discussion of this issue is in an article written by Professors M.P. Taylor and G. Filippelli earlier this year. Some excerpts from The Conversation: Wearing shoes in the house is just plain gross. The verdict from scientists who study indoor contaminants

You probably clean your shoes if you step in something muddy or disgusting (please pick up after your dog!). But when you get home, do you always de-shoe at the door?  ...continue reading "Leave Your Shoes At The Door"

Published on Leave a comment on Commonly Used Fungicide Detected In Pregnant Women and Children
Credit: Wikipedia

Another study with concerning results for children and pregnant women has been published. This time researchers found a commonly used fungicide in a majority of children and all pregnant women studied. Some children had chronic exposure. A small study, but still...

The fungicide is azoxystrobin, and is commonly used on crops (e.g., cereals, grapevines, potatoes, fruits, nuts, and vegetable crops), lawns, and in mildew and mold-resistant wallboard used in home construction. The fungicide migrates out of the wallboard (sheetrock) and is found in house dust. Thus, humans can have chronic exposure to it.

And yes, this fungicide has worrisome health effects in animal studies - for example, toxic to embryos, neurotoxicity, brain inflammation. Studies in pregnant mice found that the fungicide went from the mother to the developing babies by crossing the placenta and then entered the developing brain. Much is unknown and studies need to be done!

The problem is that in the USA chemicals are easily approved by the government for use, and it is up to consumers and researchers later to prove harm. But typically that is not enough to get any changes and the chemicals in question keep on being produced and used and causing harm.

What to do? Eat organically grown food. The fungicide is not allowed on organic crops. Don't use pesticides on your lawn. If renovating or constructing a home - avoid mold and mildew-resistant wallboard brands.

From Medical Xpress: Scientists detect common fungicide in pregnant women and children

For the first time, UNC-Chapel Hill researchers have measured the concentration of a biomarker of the commonly used fungicide azoxystrobin (AZ) in the urine of pregnant women and children ranging from 40–84 months of age. They also documented maternal transfer of AZ to mouse embryos and weaning-age mice.  ...continue reading "Commonly Used Fungicide Detected In Pregnant Women and Children"

Published on Leave a comment on Pregnant Women Are Exposed To More Chemicals and Pesticides

Some depressing news for pregnant women - they are exposed to and contaminated with more harmful industrial chemicals than ever before.

Thousands of chemicals are used in numerous consumer products and in food production (on farms, and in packaging). Not only can we get exposed to industrial chemicals from foods and products, but also from contaminated water, air, and dust.

Researchers looked for the presence of 103 industrial chemicals in the urine of pregnant women across the Unites States. The chemicals included plastics, pesticides, parabens, PAHs, as well as some of the "replacement chemicals" for BPA and phthalates. They found that most women had some of the chemicals in their bodies. Some chemicals were found in almost or ALL of them, including 3 insecticides, 2 parabens, 10 phthalates, and 1 PAH. Yikes!

Keep in mind that replacement chemicals (e.g., BPS for BPA) can be the same or even worse to health than the original chemicals.

Also, the researchers did NOT look for the presence of some commonly used chemicals (and which are linked to health harms) such as 2,4-D, pyrethroids, chlorpyrifos, and glyphosate. These are pesticides commonly used on (non-organic) farms, but also in our homes and yards. Other studies find the amounts of these pesticides are increasing in humans over the last 2 decades, and that some of these pesticides can be detected in the majority of humans.

Pregnancy is an especially important time in the life of the developing baby, and many chemicals are much more harmful then than at any other time in life. Chemicals to which pregnant women are exposed to cross the placenta - thus getting to the fetus. So it is really important to lower the amount and number of chemicals that a pregnant woman is exposed to.

How to lower your exposure to harmful chemicals: [From list of quick tips]

1) Eat as many organic foods as possible.

2) Avoid using pesticides in your home and garden, and instead look for nontoxic, organic, or least toxic IPM (Integrated Pest Management) solutions.

3) Read labels to avoid phthalates, parabens, "antimicrobial", anti-odor in personal care items.

4) Don't use dryer sheets (not needed!) or detergents or other products with fragrances.  [ Complete list of quick tips.]

Two good, but different write-ups of the research: 1) From Medical Xpress: Study of pregnant women finds increasing exposure to chemicals from plastics and pesticides

Published on Leave a comment on CDC Finds The Pesticide Glyphosate In Most Children

We all get exposed to pesticides to varying degrees - whether from our water, foods we eat, inhaling them, or absorbing them through our skin (e.g., walking or playing on pesticide treated lawns). Unfortunately, studies show our exposure to the pesticide glyphosate (found in Roundup) is increasing each year.

The CDC (Centers for Disease Control and Prevention) does biomonitoring of persons in the US to see what chemicals we are being exposed to by measuring levels in the blood and urine of both adults and children. They recently released the finding that about 80% of us have glyphosate residues. Even worse, about 87 percent of the 650 children they tested had detectable levels of glyphosate in their urine.

Glyphosate is the most widely used herbicide (it kills vegetation) in the US and the world. Nearly 300 million pounds of the pesticide are applied each year in the United States, with greater than 88.6 pounds per square mile in the US midwest (according to the USGS). Glyphosate residues have been found in all sorts of foods, honey and grain cereals.

What is it doing to us? It has been linked to a number of human health effects, such as cancer, endocrine (hormone) disruption, liver and kidney damage, preterm birth, and even having a negative effect on our gut microbiome - by killing off certain important species of gut microbes. There is much we still don't know about chronic exposure to low levels of the pesticide.

A 2017 study following adults over the age of 50 from 1993 to 2016, residing in Southern California, found that the percentage of adults with glyphosate residues in urine went from 12% to 70% during that time. And now the CDC reports an even higher rate. Much of this increase is due to genetically modified crops (crops that are Roundup resistant) and also to the increase in "preharvest" applications on regular crops.

What can you do? Eat as much organically grown food as possible. This is because organic farmers are NOT allowed to use glyphosate. And don't use Roundup or other glyphosate products on your property.
