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.]

There is something easy you can do to make flu or COVID-19 vaccines that you receive even more effective. Get some exercise after the jab and the antibodies your bodies produce in the following month will increase. It's a way to get an extra immune boost.

How much exercise? Iowa State Univ. researchers found that 90 minutes of light to moderate exercise (e.g. exercise bike or brisk walk) effective in boosting antibody production, but no benefit from 45 minutes of exercise or no exercise after vaccination.

The exercise should be started soon after getting the vaccination (in the study it was 30 minutes after getting vaccinated). By the way, the exercise did not increase vaccine side-effects.

Researchers at Iowa State University found 90 minutes of mild- to moderate-intensity exercise directly after a flu or COVID-19 vaccine may provide an extra immune boost. ...continue reading "Exercising After Getting Vaccine Boosts Antibodies"

Published on Leave a comment on Early Exposure to Foods Reduces Risk of Developing Food Allergies

Well, it looks like the medical advice for avoiding food allergies in children has come full circle. For decades health professionals said for babies to avoid eating problem foods (e.g., eggs, dairy, peanuts) if parents have food allergies. But..it turned out that following this advice did not prevent food allergies.

Results of studies in the past decade changed medical views regarding food allergies. Now the advice is: Early exposure (in the first year of life) to foods such as eggs, milk, peanut butter, and wheat is preventive - don't avoid.

A recent well done Scandinavian study confirmed that this advice is good for all young children, not just those with a family history of food allergies. Starting at 3 months of age, infants who regularly ate tiny amounts of foods (wheat, eggs, cow's milk, peanuts) had a lower chance of food allergies by 3 years of age.

Only .9% of these children developed food allergies, while 2.3% to 3% of children not getting early exposure to foods developed egg, dairy, or peanut allergies.

Also, in this study some infants had their skin rubbed with skin emollients, bath additives and facial cream from 2 weeks to 8 months, 4 times per week, and more of them developed food allergies - whether also avoiding foods or not. [My comment: Why would anyone think that would help with food allergies? It sounds irritating! And it perhaps/probably messed with their skin microbiome.]

New advice: Infants should have early exposure to potentially problem foods, starting as early as 3 months, to lower their risk of developing food allergies. Delaying the introduction of these foods actually increases the risk of food allergies. (By the way, the same advice also holds true for avoiding pet allergies - exposure to furry pets in the first year of life is important.)

From Medical Xpress: Early food introduction can reduce risk of food allergy in children

Infants who were given a taste of peanut, milk, wheat and egg from the age of three months had a lower risk of developing a food allergy at the age of three years than controls, reports a study by researchers from Karolinska Institutet in Sweden and the University of Oslo in Norway published in The Lancet. ...continue reading "Early Exposure to Foods Reduces Risk of Developing Food Allergies"

Published on Leave a comment on Certain Gut Bacteria Are Linked to Strokes

There is growing evidence that the presence of certain species of bacteria in the gut microbiome are associated with a higher stroke risk, while other bacteria are associated with a lower risk and health. Two recent studies went further and found that the presence (or higher levels) of certain bacteria are associated with severe ischemic strokes and a poorer recovery.

Ischemic strokes are the most common type of stroke. They occur when a clot or other blockage blocks the blood supply to the brain.

Both study researchers presented their findings at the European Stroke Organisation Conference (May 2022). They found that 26 species of bacteria were linked to strokes (in other words, you want less of the bacteria that increase stroke risk in your gut microbiome). Some examples of bacteria associated with strokes or poorer outcome included: bacteria of the genus Ruminococcus, species Prevotella copri, and Paraprevotella xylaniphila.

What does this mean for you? The researchers felt that changing your community of gut microbes (the gut microbiota or microbiome) could be a potential way to decrease stroke risk or stroke severity. A main way to accomplish this is by nutritional changes.

One of the researchers (Cyprien Rivier) said about the results:  "This suggests a delicate balance in the gut microbiota which can change the risk of stroke when altered."

To improve your gut microbes and lower stroke risk: most important is to improve your diet (eat a healthy diet rich in fruits, vegetables, whole grains, nuts, seeds, legumes, some fermented foods, and try to avoid highly processed foods). Also, good for gut microbes: increase your physical activity or amounts of exercise, don't smoke, and try to maintain a healthy weight. Another option is getting a fecal microbial transplant.

By the way, the beneficial microbes are NOT in dietary supplements. Must eat real food! Interestingly, an earlier study found that people who have ischemic strokes tend to have lower amounts ("depletion") of Lactobacillus sakei in the gut than healthy people.

Excerpts from Medscape: Gut Bacteria Linked to Stroke Severity, Risk

Two new studies identifying strains of gut microbiota associated with more severe strokes and worse post-stroke recovery point to a possible role for the gut microbiome in preventing stroke and improving outcomes. ...continue reading "Certain Gut Bacteria Are Linked to Strokes"

Did you know that a significant percentage of men lose the male sex chromosome in some of their cells as they age? About 40% of 70 year olds! This loss may explain why so many men die several years before women.

The loss of the male Y chromosome in some cells (mosaic loss) has health effects. It is associated with an increased risk of early death and some age-related diseases in men, such as heart disease and heart failure. This loss mainly happens in cells with a rapid turnover, such as blood cells, and does not happen in male reproductive cells.

A recent two part study in both mice and human males found that this Y chromosome loss resulted in heart muscle scarring (fibrosis), which led to increased risk of heart problems and heart failure. The researchers discuss a drug (pirfenidone) that may help with treatment.

Why is this happening? The researchers point out that as we age, more and more gene mutations are occurring, that is, the DNA of our cells accumulate mutations as we age. Some of them are due to our own choices, such as smoking, exposures to toxic chemicals, radiation, our lifestyle. Others are out of our control (e.g., aging).

From Science Daily: Loss of male sex chromosome leads to earlier death for men

The loss of the male sex chromosome as many men age causes the heart muscle to scar and can lead to deadly heart failure, new research from the University of Virginia School of Medicine shows. The finding may help explain why men die, on average, several years younger than women. ...continue reading "Many Men Lose the Male Sex Chromosome As They Age"

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.

Published on Leave a comment on Thirty States Report Chronic Wasting Disease In Deer and Elk

The United States has a growing problem. The number of cases of the always fatal Chronic Wasting Disease (CWD) is steadily spreading among wild game (elk and deer) and has now been found in 30 states. In October 2020 it had been detected in 26 states, Dec. 2021 in 27 states, and as of April 2022 the US government reported it in 30 states!

Chronic wasting disease (CWD) is a prion disease similar to "mad-cow disease" (bovine spongiform encephalopathy) in cattle and Creutzfeldt-Jakob's disease in humans. There is no cure or treatment, and it is always fatal. While up to now CWD has only been found in deer and elk, the concern is that this disease will jump to humans, especially in people who eat contaminated meat.

Chronic wasting disease (CWD) should be of concern to all hunters or people who eat wild-caught game (deer, elk, moose, reindeer). No human cases have been detected, but health officials and the CDC warn people to avoid eating meat from CWD infected animals.

Symptoms of the disease: In chronic wasting disease there is a long incubation period, followed by the brain become progressively like a sponge - riddled with holes, along with deterioration in brain function, behavioral changes, and eventually death. A horrible slow death. There are no treatments or vaccines.

How is it spread? Scientists believe CWD prions spread between animals through body fluids (e.g., feces, saliva, blood, or urine), either through direct contact or indirectly through environmental contamination of soil, food or water. Once introduced into an area or farm, the CWD prion (protein) is contagious within deer and elk populations and spreads.

Once CWD gets into the soil, it stays there for years, and so animals can contract it even after infected deer and elk have died. Yikes!

How do you get rid of it? Unfortunately, high heat, disinfectants, and radiation don't kill the CWD prions. Dr.Zabel at the Colorado State Univ. Prion Research Center suggested a few years ago that controlled burns (fires) of infected fields or areas could eliminate the prions left behind by infected animals (from animal mucus/saliva, urine, and feces, and decaying carcasses) on plants and soil. ...continue reading "Thirty States Report Chronic Wasting Disease In Deer and Elk"

Published on Leave a comment on Just Looking At and Smelling Food Can Trigger Release of Insulin

For years, many individuals have joked that just looking at food makes them gain weight. Well, maybe the joke was not too far of the mark.... Recent research found that just looking at and smelling food triggers the release of insulin.

In other words, just the sensory cues of food are enough to stimulate receptors in the brain and the nervous system to result in the pancreas secreting insulin. This is what normally happens in healthy individuals - and it's called the cephalic phase of insulin release.

Interestingly, in very overweight (obese) humans and mice, this response can be impaired.

From Science Daily: The mere sight of a meal triggers an inflammatory response in the brain

Even before carbohydrates reach the bloodstream, the very sight and smell of a meal trigger the release of insulin. For the first time, researchers from the University of Basel and University Hospital Basel have shown that this insulin release depends on a short-term inflammatory response that takes place in these circumstances. ...continue reading "Just Looking At and Smelling Food Can Trigger Release of Insulin"

Published on Leave a comment on The Flu Vaccine is Linked to a Lower Risk of Developing Alzheimer’s Disease

Fabulous news for those persons wanting to reduce their risk of Alzheimer's disease as they age - get a flu vaccine, especially annually. A recent large study found that with each annual vaccine received in adults 65 years and older, the protective effect increases. That's it! So simple.

The study authors compared 935,887 flu-vaccinated patients and 935,887 non-vaccinated patients. At the start of the study, no one had an Alzheimer's diagnosis. They found a 40% lower risk of an Alzheimer's diagnosis in those receiving flu vaccines compared to individuals not receiving a flu vaccine in the following 4 years.

Other studies have had similar findings, as well as that getting other vaccines in adulthood also reduce the risk of dementia, such as pneumonia, tetanus, polio, and herpes vaccines. Current thinking is that this protective effect from vaccines is due to their immunological effects - that they boost the immune system in a good way.

From Science Daily: Flu vaccination linked to 40% reduced risk of Alzheimer's disease

People who received at least one influenza vaccine were 40% less likely than their non-vaccinated peers to develop Alzheimer's disease over the course of four years, according to a new study from UTHealth Houston. ...continue reading "The Flu Vaccine is Linked to a Lower Risk of Developing Alzheimer’s Disease"

Published on Leave a comment on Youngest Children in a Class Are At Increased Risk of ADHD Diagnosis and Medication

Another recent study gave support to what has been known for decades - the youngest children in a class, especially boys, are most likely to be diagnosed and treated medically for attention deficit hyperactivity disorder (ADHD) or other behavioral problems.

Of course the youngest children in a class are - it's called immaturity. In a class there can be a 12 months age difference between the oldest and youngest children. Younger, more immature children have a harder time sitting still and focusing for hours, plus all those worksheets.... No wonder they are at increased risk for ADHD diagnoses and having to take medications.

The large study conducted in Scotland in Wales found that flexibility in when a child starts school helps lower the risk of an ADHD diagnosis. And if necessary, a child should stay back a year (repeat the school year)

Another thing to keep in mind -  it's especially hard for active children when recesses are eliminated, as so many schools are now doing.

From Medical Xpress: Youngest children within their school year are more likely to be treated for ADHD, says new study
