Published on Leave a comment on Eating Organic Foods Lowers Pesticide Levels In the Body

We all have some pesticide residues in our body, and the levels vary. One way that people are exposed to pesticides is from the foods they eat, specifically non-organic foods. Pesticides that people are exposed to can be measured in the blood and urine. 

A recent review of 72 scientific studies found that people who eat an organic diet have lower pesticide levels in their urine. (Other pesticide exposures are from the environment around us, for example, garden and lawn pesticides.)

The study authors specifically looked at pesticide residues and metabolites of common pesticides such as organophosphates, pyrethroids, 2,4-D, and glyphosate. The most commonly mentioned pesticide residue was from pyrethroids, with 34% of studies finding it in urine. Keep in mind that only a limited number of pesticide residues were looked for. In reality, people are exposed to many more in life, including from non-organic foods that they eat.

Looking at the studies, the researchers found a massive reduction in pesticide residues when an organic diet is adopted. For example, phenol and phosphonate herbicide levels drop 41% to 100% in the studies, and pyrethroid metabolites dropped 16% to 100% [Note: each study had different drops in pesticide residues.]

And yes, you want lower levels of pesticide residues in your body for health reasons. For example, pyrethroids have been associated with numerous health harms, including cancer, endocrine disruption, and reproductive effects.

Bottom line: To lower pesticide levels in your body, eat as many organic foods as possible.

Excerpts from Beyond Pesticides: Review of Pesticide Residues In Urine, Lower Concentrations With Organic Diet

 A literature review, published this month in the Journal of Agricultural and Food Chemistry, explores levels of pesticide residues found in samples of human urine with environmental exposure and dietary intake and confirms prior findings about the benefits of an organic diet. Similar to past findings, lower concentrations of chemicals are detected in the urine of participants who report eating an organic diet. ...continue reading "Eating Organic Foods Lowers Pesticide Levels In the Body"

Published on Leave a comment on Diet and Risk of Developing Dementia

One message keeps being supported by research: Eat a diet rich in fruits, vegetables, seeds, nuts, whole grains, legumes, and olive oil. A reason is because this diet is anti-inflammatory. And it turns out that inflammation is at the root of many diseases, including heart disease. And dementia.

A recent study that followed more than 84,342 older adults (60 years or older at the start of the study) found that those who ate an anti-inflammatory diet had a 21% lower chance of developing dementia. They also had larger gray matter volume in the brain, and smaller white matter lesions or spots in the brain (white matter hyperintensity volume). All of the adults had cardiometabolic diseases (e.g., heart disease, diabetes, stroke) at the start of the study.

Other studies have already confirmed that eating an anti-inflammatory diet (e.g., Mediterranean diet) is linked to lower risk of diabetes, heart disease, lower dementia risk, better cognitive function, and better brain aging (as measured by MRI scans).

Published on Leave a comment on Low Levels of Magnesium Can Increase the Risk of Some Diseases

A diet rich in a variety of healthy foods (fruits, vegetables, whole grains, seeds, nuts, legumes) is important because of all the micronutrients it provides. For example, magnesium. A recent study found that low magnesium levels are linked to an increased risk of DNA damage and chronic diseases.

The reason is that low levels of magnesium in the body are associated with high amounts of homocysteine. The researchers felt that the study results indicate that "sufficiently high magnesium levels in the blood are essential to protect our genes from toxicity caused by homocysteine". Homocysteine levels increase when folate and B12 levels are deficient.

Some magnesium facts: It's the 4th most abundant mineral found in the body. It is involved with various functions in the body, including strengthening and development of bones, nerve function, regulating blood sugar and blood pressure, and DNA repair.

Magnesium rich foods are whole grains, dark green leafy vegetables (especially spinach and kale), nuts (especially, almonds, cashews, peanuts), beans, seeds (especially pumpkin and chia seeds), potatoes, rice, oatmeal, bananas, and dark chocolate.

Published on Leave a comment on More Reasons To Avoid Artificial Sweeteners

The artificial sweetener erythritol is added to many foods. However, this sugar substitute (which is often blended with stevia) may cause health problems . A recent small study found that consuming typical "sugar-less" foods, such as erythritol sweetened drinks or erythritol sweetened muffins, more than doubled the risk of blood clotting in healthy volunteers.

After consuming the drinks, their bodies made platelets (a type of blood cell) more active, which can raise the risk of blood clots. This did not happen after consuming regular sugar (glucose).

The researchers suggest instead of artificial sweeteners, to use sugar, honey, or fruit, but in moderation.

From Medical Xpress: New study adds to increasing evidence that sugar substitute erythritol raises cardiovascular risk

New Cleveland Clinic research shows that consuming foods with erythritol, a popular artificial sweetener, increases the risk of cardiovascular events such as heart attack and stroke. The findings, from a new intervention study in healthy volunteers, show erythritol made platelets (a type of blood cell) more active, which can raise the risk of blood clots. Sugar (glucose) did not have this effect. ...continue reading "More Reasons To Avoid Artificial Sweeteners"

Published on Leave a comment on Cranberry Juice Helps Prevent Urinary Tract Infections

A recent review of studies looked at whether cranberry juice helps with urinary tract infections (UTIs) and the results were encouraging. Yes, cranberry juice or cranberry tablets help in preventing UTIs.

Twenty well-done studies were reviewed. Drinking cranberry juice or taking a cranberry tablet resulted in a 27 to 54% lower rate of UTIs (the numbers varied between studies), and a 49% to 59% lower rate of antibiotic use. Cranberry compounds reduced the prevalence of UTI symptoms. These are great results!

The majority of women suffer from a UTI at some point in their life, and some women suffer frequently - many times a year. Antibiotics have long been the treatment of choice, but antibiotic resistance is increasing, so finding something that prevents UTIs is important.

By the way, cranberries and cranberry juice has been promoted for decades as both UTI prevention and treatment. [Other treatment possibilities for treatment and prevention are: D-mannose, drinking more water, the probiotic L. crispatus, and an oral vaccine.]

Published on Leave a comment on Eating Ultra-Processed Plant-Based Foods Is Not Healthy

Eating plant-based foods has health benefits. But only if it's from real foods, and not ultra-processed. A recent study found that the more not ultra-processed plant-based foods a person ate (and the less ultra-processed plant-based foods), the lower their risk of cardiovascular disease  and early death.

The results show that eating minimally processed food is heart protective. And the reverse is also true: higher consumption of plant-based ultra-processed foods was associated with a greater risk of heart disease (including heart attacks and strokes) and early death from heart disease.

Read the ingredient lists! When there are ingredients that are not normally found in your kitchen (e.g., carrageenan, artificial or natural flavors, titanium dioxide, soy lecithin, high-fructose corn syrup, cellulose) - then they are ultra-processed foods. Ultra-processing strips away a food's nutrients, as well as fiber.

Yes, trying to lower consumption meat consumption and eating more plant-based foods is a good goal. But...Many meat-free foods (e.g., boxed macaroni and cheese), dairy substitutes, and plant-based "meats" are not healthy. Lots of chemicals were added to make it more meat-like or a dairy substitute - thus they are ultra-processed foods.

Packaged breads, buns, cakes, cookies and soda are meat free and plant-based foods, but they generally are ultra-processed.

Bottom line: Try to eat more fresh, frozen, or minimally plant-based foods. This is a diet rich in whole grains, fruits, vegetables, legumes (beans), seeds, nuts. A good example is a Mediterranean-style diet, which has been shown to have many health benefits.

From Washington Post: When plant foods are ultra-processed, the health benefits disappear

Eating a plant-based diet is good for your health, but not if those plant foods are ultra-processed, a new study has found.

The findings show that all plant-based diets aren’t the same, and that plant foods can have very different effects on your health depending on what manufacturers do to them before they reach your plate. ...continue reading "Eating Ultra-Processed Plant-Based Foods Is Not Healthy"

Published on Leave a comment on A Mediterranean Style Diet Feeds Beneficial Gut Bacteria

The incidence of both intestinal bowel diseases (IBD) and colorectal cancer is rapidly increasing in developed countries (e.g., US, Canada, Europe). There are many theories over why this is occurring, with most researchers thinking a person's diet plays a role. A big suspect in promoting IBD and colorectal cancer is the Western diet, which has lots of ultra-processed foods and is also low in fiber.

A recent large study looked at 6 major diets and how they impact the gut microbiome. The six dietary patterns were: Western diet, Mediterranean diet, high-fiber diet, plant-based diet, high protein diet, and ketogenic diet.

And surprise, surprise - eating a Western diet resulted in having an increase in gut bacterial species linked to chronic inflammation, heart disease, colorectal cancer, IBD, and diabetes. The Mediterranean style diet had an increase in bacterial species linked to a lower risk of cardiovascular disease, IBD, and type 2 diabetes. In fact, all 6 diets had distinct bacterial profiles in the gut.

Bottom line: The foods a person eats can either feed and nourish beneficial bacteria or harmful bacteria (linked to cancer and IBD). Best for health is a Mediterranean style diet (lots of fruits, vegetables, whole grains, legumes, seeds, nuts), and avoiding ultra-processed foods. You are what you eat!

Cardinal flowers    Credit: M. Silgailis

Hummingbirds like the red Cardinal flower (also called lobelia). Really like them. Butterflies also swarm to these flowers. Usually.

But not always. Since an immediate neighbor started using a mosquito service that uses high-volume pesticide applications of a synthetic pyrethroid (think of a leaf blower on steroids), there has been an absence of butterflies, bees, and hummingbirds in my garden. Other people also report this happening.

Even though the synthetic pyrethroids (e.g., Fendona) are not neonicotinoids, which we know kills bees - pyrethroids are also toxic to bees. Pyrethroids are broad-spectrum insecticides - that is, they kill a wide variety of insects indiscriminately. This totally destroys the biodiversity of species in the environment. We need bees, butterflies, hummingbirds, and other species!

But what are the pesticides doing to humans? Developing children? The developing fetus? Sick people? Everyone? Yes, there is accumulating evidence of health harms to humans, especially children and babies.

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 Appendix Has Health Benefits

Over  time researchers have learned that the appendix is more complex than originally thought, and that it is beneficial to health. It's where good bacteria go to hideout during sickness (e.g., food poisoning) or when a person is taking antibiotics, and it acts as a "training camp" for the immune system.

This is the direct opposite of what was thought for years - that it is a vestigial organ with no purpose. Instead, research found that removing the appendix increases the risk for irritable bowel syndrome and colon cancer. It also plays a role in several medical conditions, such as ulcerative colitis, colorectal cancer, Parkinson's disease, and lupus.

One possibility is that it protects against diarrhea. The appendix acts as a safe house for beneficial bacteria. We now know that it contains a thick layer of beneficial bacteria. People who've had their appendix removed have a less diverse gut microbiome, and with lesser amounts of beneficial species.

By the way, recent research found that antibiotics can successfully treat up to 70% of uncomplicated appendicitis cases. For this reason, it is recommended that antibiotics should be tried first in uncomplicated appendicitis cases. And if needed (e.g., if there are recurrences of appendicitis) surgery can be done.

Excerpts from Medscape: The 'Useless' Appendix Is More Fascinating Than We Thought

When doctors and patients consider the appendix, it's often with urgency. In cases of appendicitis, the clock could be ticking down to a life-threatening burst. Thus, despite recent research suggesting antibiotics could be an alternative therapy, appendectomy remains standard for uncomplicated appendicitis.

But what if removing the appendix could raise the risk for gastrointestinal (GI) diseases like irritable bowel syndrome and colorectal cancer? ...continue reading "The Appendix Has Health Benefits"
