Published on Leave a comment on Pesticides and Pediatric Cancers

Cancer is feared by all. It seems to strike randomly, but not always. Certain cancers that occur in both children and adults, such as brain cancer and leukemia, are linked with some commonly used pesticides. Exposures to these pesticides occur many ways - whether from nearby  farm use, or in foods or the water  we drink, or air (pesticide drift), or residential use (e.g., the weed killer 2,4-D on lawns). Exposure is typically not to just 1 harmful chemical, but to mixtures of pesticides, especially on farms.

Children are especially vulnerable to pesticides. Research shows that there is an increase in some cancers in children in farm areas (e.g., Nebraska and the US midwest) where pesticides are heavily used. A recent study by Dr. Taiba and colleagues found that in Nebraskan counties with heavy farm pesticide use (especially Holt county) children living there had an increase not just in "overall pediatric cancers", but in specific types of cancers. These cancers included brain and other central nervous system tumors, leukemia, and lymphoma.

Keep in mind that in the US millions of pounds of pesticides are used each year, with farm areas having the heaviest use. Dr. Taiba reported that the US is the #1 country in the world in pesticide use. Among the most heavily used in the Nebraskan farms are atrazine, 2,4-D, glyphosate, dicamba, paraquat.

But don't ignore residential use of pesticides. Many of the same pesticides, such as glyphosate and 2,4-D, are commonly used in residential areas, especially for weed and insect control. Feed and Weed, which is used on lawns for weed control, contains 2,4-D. Pesticides have harmful effects on humans, and yet pesticide use is increasing annually.

From Beyond Pesticides: Dire Pediatric Cancer Risk Linked to Pesticide Mixtures, Laws To Protect Children Found To Be Lax

Childhood cancers are on the rise globally; in the U.S. cancer is the second most common cause of death in children between one and 14 years old, and the fourth most common in adolescents. A recent study of Nebraska pesticide use and pediatric cancer incidence by researchers from the University of Nebraska Medical Center and the University of Idaho Department of Fish and Wildlife Sciences found positive associations between pesticides and overall cancer, brain and central nervous system cancers, and leukemia among children (defined as under age 20). ...continue reading "Pesticides and Pediatric Cancers"

When looking at the research, it is striking that so many chemicals that we are exposed to daily are harming us. Health harms include an increase in certain cancers (e.g., brain cancer and leukemia from certain pesticides) and reproductive effects. This can be seen clearly when research shows that sperm counts are declining globally 2.64% per year since 2000.

A recent report from HEAL (Health and Environmental Alliance in the European Union) found that along with this, infertility rates, testicular cancer, and prostate cancer are increasing. This is alarming!

HEAL’s report (author Dr. Cannarella) details alarming indications of catastrophe in male reproductive health: prostate cancer, testicular cancer, crashing sperm counts, infertility, and numerous developmental problems including cryptorchidism, urogenital malformations, and hypospadias. The report highlights pesticides, microplastics, phthalates, bisphenols, PFAS and heavy metals as the likely environmental sources of the crisis. There is evidence that all of these endocrine disrupting chemicals (EDCs) adversely affect male reproductive function.

Excerpts from the latest research on the drop in sperm counts globally and declines in male reproductive health, the science report from HEAL: Chemical pollution and men’s health: A hidden crisis in Europe

A 2023 meta-analysis by Levine et al. showed that global sperm counts declined by 52% between 1973 and 2018. European countries showed similar or even steeper declines, especially in Western and Southern Europe. ...continue reading "Male Sperm Counts Continue to Decline"

Credit: Wikipedia

The list of health harms from ultra-processed foods just keep growing. Unfortunately, most Americans get the majority of their calories from ultra-processed foods. A recent series of studies found that ultra-processed foods harm every one of our major organs. They increase the risk of many chronic diseases (e.g., heart disease, type 2 diabetes, obesity ) and early death.

How do you know a food is ultra-processed? Look at the ingredient list and if there is something that normally is not found in a person's kitchen, then it is ultra-processed. Examples of such ingredients are: emulsifiers, carrageenan, mono- and diglycerides, soy lecithin, polysorbate, cellulose, colors, titanium dioxide, high fructose corn syrup, hydrogenated oils, dextrose, whey protein, nitrates, flavors (artificial and natural), colors, etc. (Yes, natural flavors are laboratory concoctions.)

Ultra-processed foods are food products manufactured with all sorts of ingredients (additives) that have been added to extend shelf-life or manipulate the taste, flavor, or appearance. Ultra-processed foods are "formulations of ingredients" that result from a series of industrial processes (thus "ultra-processed").

Bottom line: Read labels! Try to avoid foods with ingredients not normally found in your kitchen. Try to eat as many whole foods and minimally processed foods as possible.

Excerpts from The Guardian: Ultra-processed food linked to harm in every major human organ, study finds

Ultra-processed food (UPF) is linked to harm in every major organ system of the human body and poses a seismic threat to global health, according to the world’s largest review.UPF is also rapidly displacing fresh food in the diets of children and adults on every continent, and is associated with an increased risk of a dozen health conditions, including obesity, type 2 diabetes, heart disease and depression.

Published on Leave a comment on Eating Peanut Products In Infancy Reduces the Rate of Peanut Allergies

Some more good news on the peanut allergy and other food allergy front. In 2015, medical advice changed to : Yes, please introduce tiny amounts of foods such as peanuts and eggs in the first year of life to prevent food allergies. And...since then, the incidence of food allergies, including peanut allergies, in children has dramatically gone down when that advice is followed.

A recent study found that the incidence of peanut allergies in children has really dropped since parents started introducing peanut products in infancy. Introducing tiny amounts frequently of the food of concern (nuts, eggs, etc.) in the first year of life (by 4 to 6 months of age) challenges and trains the immune system. [Official instructions on how to feed peanut products to infants]

Unfortunately, many doctors and parents are still not following the advice because it is so opposite from earlier medical advice, which for decades said to avoid, avoid, avoid the food (e.g., nuts, eggs) in early childhood. It is thought that if more doctors and parents followed the new advice for infants, then food allergy rates would drop even more.

By the way, the rate of dog and cat allergies also drops when there is more furry animal exposure in the first year of life. Same reason.

From Medscape: Food Allergy Rates Fall After 2015 Peanut Feeding Advice

Peanut allergies in babies and children up to age 3 dropped by more than one-quarter since the first consensus statement recommending the introduction of peanut products in infancy was issued in 2015, according to a new study published in Pediatrics. ...continue reading "Eating Peanut Products In Infancy Reduces the Rate of Peanut Allergies"

Published on Leave a comment on Weed-Killer Glyphosate and Cancer

Remember when back in 2015 the IARC (International Agency for Research on Cancer) said that the pesticide glyphosate (the active ingredient in Roundup) is a probable human carcinogen (cancer causing)? And the American chemical industry and FDA pooh-poohed that? Well, there have been a number of studies since then finding that yes, glyphosate results in tumors and other health harms, and is cancer causing (carcinogenic).

Glyphosate is a commonly used herbicide (weed killer), the most used herbicide in the world. Its use has been increasing annually, especially due to the increase in genetically modified crops being grown.

In the latest study, an international team of researchers found that long-term daily exposure (starting prenatally and continuing after birth) to low glyphosate levels considered "safe" by government agencies resulted in multiple benign and malignant tumors, and increased rates of early death in the rats after birth. Yes, the study was done with rats, but... they are mammals, just like us humans. Rats are frequently used in studies to assess chemical safety.

The doses used in the study are currently considered safe by regulatory agencies and correspond to the EU Acceptable Daily Intake (ADI) and the EU’s No Observed Adverse Effect Level (NOAEL) for glyphosate. By the way, European standards are STRICTER than USA standards. A person eating a typical diet with non-organic foods easily ingests the levels considered acceptable by European governing bodies, and in the US ingests even more. [NOTE: Eat organic foods to avoid glyphosate.]

From Environmental Health News: Common pesticide causes multiple malignant tumors in rats

In short: Exposure to glyphosate herbicides caused multiple benign and malignant tumors in rats, including leukemia and cancers of the skin, liver, thyroid, nervous system, ovary, uterus, and kidneys, among others. ...continue reading "Weed-Killer Glyphosate and Cancer"

A recent study found that there is an increased risk of blood cancers occurring in  children who receive X-rays and CT scans. And as the number of X-rays and CT scans go up (thus an increase in total cumulative dose of radiation), the risk of a blood cancer also increases.

The researchers refer to these increased number of cancers as "radiation-induced hematologic cancers". These include such cancers as  lymphoid cancers, leukemia, and histiocytic- or dendritic-cell cancers. They estimated that the number of these radiation-induced cancers is 1 in 10 blood cancers in children.

They advise only getting X-rays and CT scans if necessary, and consider getting an MRI or ultrasound instead (if possible).

From Medical Xpress: Study finds 10% of pediatric blood cancers may stem from medical imaging radiation

A study led by UC San Francisco and UC Davis has concluded that radiation from medical imaging is associated with a higher risk of blood cancers in children.

The researchers examined data from nearly 4 million children and estimated that one in 10 blood cancers—some 3,000 cancers in all—may be attributable to radiation exposure from medical imaging. The risk increased proportionally based on the cumulative amount of radiation the children received. ...continue reading "Medical Imaging Radiation and Increased Risk Of Blood Cancers In Children"

Published on Leave a comment on Chemicals of Concern Found In the Bodies of Young Children

Once again, those wondering about the chemicals lurking inside us have bad news. In a long-running study, researchers tested 201 young children (aged 2 to 4 years old) and found that all of them have many dangerous chemicals ("chemicals of concern") in their bodies. Some of the chemicals were in higher levels in the children than in their mothers during pregnancy.

In this study pregnant women from 4 states had their urine analyzed, and later the urine of their children when they were 2 to 4 years old. The testing of blood and urine from a person and looking for certain chemicals is called biomonitoring.

The researchers only looked for  111 chemicals and found that at least 5 children had 96 of them detected in their urine. Over 50% of the children had 48 chemicals detected. Thirty four of the chemicals were detected in over 90% of the children. But keep in mind that they only looked for a limited number of chemicals. Some of the chemicals found are not being monitored in adult biomonitoring. Many chemicals we are routinely exposed to, such as the common pesticide glyphosate (found in many non-organic foods) were not looked at.

One trend the researchers found is that levels of 2,4-D (pesticide used as a herbicide or weed-killer) are trending upwards over time. This is because 2,4-D is commonly used as a weed-killer on lawns (including Feed and Weed) and elsewhere, but it is also used on genetically modified crops.

The 111 chemicals tested for are from the foods and beverages children (and adults) ingest, personal care products (e.g., soap, lotion), the chemicals used in the home (e.g., pesticides, cleaning products) or chemicals outgassing from products used in the home (e.g., from non-stain synthetic rugs, plastic toys, vinyl floors). Children are exposed to the chemicals when they breathe indoor and outdoor air, eat food, touch surfaces or objects - both indoors and outdoors.

Bottom line: Eat as many organic foods as possible (pesticides such as 2,4-D and glyphosate are not allowed in organic food production). Additional tips: Lifestyle tips for avoiding harmful chemicals.

Excerpts from Science Daily: Researchers tested 200 toddlers — 96 chemicals were lurking in their bodies

A national study published in Environmental Science & Technology finds children aged 2 to 4 years in the United States are routinely exposed to a broad range of potentially harmful chemicals. Many of the chemicals the researchers identified are not routinely monitored and may pose health risks. ...continue reading "Chemicals of Concern Found In the Bodies of Young Children"

Published on Leave a comment on Exposures to Pesticides and Childhood Cancer Risk

The US is awash in pesticides - whether used on farms, in homes, on lawns, right-of-ways, on flea collars, etc., etc. They are used for specific reasons (e.g., to kill specific pests or weeds), but they also cause harms. People have more exposure to pesticides than they realize, and this results in health harms, especially to children and during pregnancy.

For example, people are exposed when there is drifting of pesticides to non-target areas when applied, or there is contamination of drinking water, or from the pesticide residues in the foods we eat, touching dogs wearing flea collars, or when children play on treated lawns.

A large study found that exposure to multiple pesticides results in an increased risk of childhood cancers - brain cancer by 36%, leukemia rates by 23%, and overall pediatric cancer rates by 30%. The study was done in Nebraska, the state with the second highest cancer rates. Many scientists, and also researchers of the study, believe this is from extensive use of multiple pesticides on crops.

Unfortunately, the government only looks at exposure to one chemical at a time - not the mixtures we are exposed to on a daily basis. Also, the most toxic pesticides (dicamba, paraquat, glyphosate) are more regulated or banned in Europe, but not in the US. (Remember: $$$ first in the US).

Simple steps you can do to lower your pesticide exposure: 1) Eat as many organic foods as possible. Pesticide levels in the body will rapidly go down. 2) Use non-toxic Integrated Pest Management (IPM) or organic methods for pest problems. 3) Don't use pesticides on the grounds where you live. View lawns as having wildflowers (bee habitats!) and not weeds. 4) Take your shoes off at the door (so you don't track in pesticides). 5) Use some sort of water filter for drinking water if you suspect that there are pesticides in your water.

From The Guardian: Exposure to combination of pesticides increases childhood cancer risk – study

Exposure to multiple pesticides significantly increases the risk of childhood cancers compared with exposures to just one pesticide, first-of-its-kind research finds, raising new fears that children are more at risk to the substances’ harmful effects than previously thought. ...continue reading "Exposures to Pesticides and Childhood Cancer Risk"

Published on Leave a comment on Better Lung Function In Children Living Near Green Spaces

A recent large study found that exposure in childhood to more "green spaces" or a "greener neighborhood" results in better lung function in those children. Well, duh.. of course. The study needed to be done to show the health benefits of parks and other outdoor green spaces for children, and thus the need for green spaces in urban areas.

The study involved more than 35,000 children from eight European countries. They found that the more "green space" or "greener neighborhoods" exposure (meaning the more green spaces by the child's residence) that the children had in early childhood, the better it was for their lung function. On the other hand, the further away a child lived from green spaces, the lower the lung volume.

Why? The researchers point out that green spaces (parks, yards) reduce air pollution, which in turn affects respiratory health of children. It also exposes the children to beneficial microbes, which are good for their microbiome and immune system. Finally, playing outside (physical activity) is good for lung development and function.

From Science Daily: Children living in greener neighborhoods show better lung function

A large study of 35,000 children from eight countries has found a "robust" link between exposure to green spaces in early childhood and better lung function. The study, led by the Barcelona Institute for Global Health (ISGlobal), has been published in Environment International. ...continue reading "Better Lung Function In Children Living Near Green Spaces"

Published on Leave a comment on The EPA Reverses Course and Now Proposes Banning Toxic Pesticide

Update to the toxic pesticide acephate story of last week. Well, well, well.... Due to the big outcry after ProPublica's story exposing EPA's recent decision to relax standards and so allow much more of the toxic pesticide acephate in our food, the officials at the EPA changed their minds and now propose banning it! 

Acephate is an insect killer commonly used on celery, lettuce, cauliflower, tomatoes, peppers, and other fruits and vegetables, and residues stay on produce that we eat. It also contaminates drinking water. (It's used on non-organic crops, but it's not allowed to be used on organic crops.)

Propublica's story broke on April 24, 2024, and immediately afterwards there was outrage over the EPA's relaxing of the pesticide standards decision. This is because the FDA was totally ignoring years of scientific and medical research showing harms to humans, and only accepting and believing what the pesticide industry told them. It even ignored its own scientists and advisory groups.

Acephate is a pesticide known to be so harmful that it was BANNED in Europe more than 20 years ago, yet allowed in the US. A major reason: harmful effects on the developing brains of fetuses and children, and linked to autism, hyperactivity, and reduced scores on intelligence tests. In 2023, the CDC said that autism spectrum disorder rates have now increased to 1 out of every  36 births.

Now we wait and see: Will the FDA (once again) cave to industry or actually do what they are supposed to do - protect consumers? 

ProPublica is a non-profit investigative journalism site. The following are excerpts from their May 1, 2024 story on the FDA reversal. From ProPublica: EPA Proposes Ban on Pesticide Widely Used on Fruits and Vegetables

The Environmental Protection Agency unveiled a proposal this week to ban a controversial pesticide that is widely used on celery, tomatoes and other fruits and vegetables. ...continue reading "The EPA Reverses Course and Now Proposes Banning Toxic Pesticide"
