Alopecia Awareness: Uncovering the Role of Toxic Mold and Autoimmune Conditions

Alopecia Awareness: Uncovering the Role of Toxic Mold and Autoimmune Conditions

by | Oct 1, 2024 | Environmental Health, Immune Health, Naturopathic Medicine

Throughout my experience as a naturopathic doctor, I've personally witnessed the devastating effects that toxic mold exposure from water-damaged homes —an issue affecting an estimated 45% of buildings—can have on patients. From fibromyalgia to chronic fatigue and even alopecia, mold illness can trigger a cascade of debilitating symptoms. My passion for environmental health drives me to help people heal from these often-overlooked conditions, particularly mold-related illness, which I’ve received additional training to manage. Naturopathic doctors are uniquely trained in environmental medicine, making us well-equipped to address issues like toxic mold exposure. As we dive into Alopecia Awareness Month, I want to share some insights into the connections between hair loss, autoimmune thyroid disease, and toxic mold exposure, and what you can do to protect your health.

What is Alopecia Awareness Month?

Alopecia Awareness Month is observed every September to raise awareness about alopecia, its causes, and the impact it has on individuals’ lives. Alopecia is a term used for hair loss, which can range from thinning hair to complete baldness. While it’s often attributed to genetics and stress, other underlying health factors such as autoimmune diseases and environmental exposures—like mold—can play a significant role.

The Connection Between Autoimmune Thyroid Disease and Alopecia

Autoimmune disorders, particularly thyroid disease, are commonly linked to hair loss. Thyroid hormones regulate many essential bodily functions, including hair growth. When the thyroid is underactive or overactive, it can lead to hair thinning or even patches of hair loss known as alopecia areata.

Hypothyroidism and Hair Loss

In my practice, I've encountered numerous cases where individuals with Hashimoto's thyroiditis, an autoimmune form of hypothyroidism, experience varying degrees of hair loss. Hashimoto’s leads to a gradual reduction in thyroid hormone production, causing the hair follicles to weaken and fall out. The immune system's role in attacking the thyroid can also extend to attacking hair follicles, which is why autoimmune thyroid disorders are so frequently associated with alopecia. Understanding this connection helps us better support both thyroid health and hair loss in patients.

The Connection Between Toxic Mold and Alopecia

Toxic mold exposure is an often-overlooked contributor to health issues, including alopecia. Mold thrives in water-damaged buildings, and with so many homes affected, it’s not uncommon to see patients who are suffering from mold-related illnesses. These illnesses can manifest in many ways, including fatigue, respiratory problems, and, in some cases, hair loss.

Mold and Hair Loss: What’s the Link?

Exposure to mycotoxins, harmful chemicals produced by toxic mold, can weaken the immune system, leading to systemic inflammation and immune dysregulation. When the body is exposed to mold toxins, it can trigger inflammation in hair follicles, leading to conditions like alopecia. Additionally, mold exposure often disrupts the hormonal balance, affecting thyroid function, which can further exacerbate hair loss.

In cases of mold toxicity, I’ve seen patients struggle with a variety of chronic symptoms that can range from cognitive issues and muscle pain to unexplained hair loss. By addressing mold exposure through detoxification and environmental interventions, many patients have experienced significant improvement, including regrowth of their hair.

The Change the Air Foundation and Their Journey with Alopecia and Toxic Mold

One powerful example of the connection between toxic mold and alopecia is the story behind the Change the Air Foundation. This organization was born out of a family’s experience with mold-related illness, which led their young daughter to develop alopecia universalis, the total loss of all hair on the body. After enduring hair loss and a range of debilitating symptoms, they discovered that mold exposure was the underlying cause. Their journey to recovery, chronicled here, inspired the family to start the foundation. Their mission is to raise awareness about indoor air quality and toxic mold, helping families understand the often-hidden risks of mold exposure and providing resources for recovery. The foundation’s work continues to shine a light on the profound impact that environmental health can have on conditions like alopecia and many other chronic illnesses.

Managing and Addressing Alopecia Linked to Thyroid Disease and Mold Exposure

If you suspect your hair loss is linked to autoimmune thyroid disease or toxic mold exposure, seeking appropriate testing and support is essential. Naturopathic doctors, who receive specialized training in environmental medicine as part of their curriculum, are particularly skilled at identifying and managing mold-related illnesses.

1. Address Thyroid Health

For those with autoimmune thyroid conditions like Hashimoto’s, managing thyroid hormone levels can minimize the risk of hair loss. This may include thyroid hormone replacement therapy, along with a diet rich in essential nutrients like iodine and selenium, both of which support thyroid function and hair growth.

2. Combat Mold Exposure

For patients dealing with mold exposure, the first step is identifying and removing the mold source. When it comes to mold inspection and testing, I’ve found the most thorough results come from professionals with specific certifications such as Council-certified Microbial Investigator (CMI) or Council-certified Microbial Consultant (CMC). These individuals are trained to perform detailed mold inspections, bioaerosol sampling, and lab result interpretation. They can also design effective remediation protocols and conduct post-remediation testing to ensure the mold has been successfully eliminated. By working with professionals who hold these credentials, you can ensure that the mold issues are accurately identified and resolved.

3. Modulate the Immune Response

Since both autoimmune thyroid disease and mold exposure involve immune dysfunction, strategies to modulate the immune system, such as reducing stress, improving gut health, and incorporating immune-balancing supplements, can provide additional support.

Final Thoughts

As we observe Alopecia Awareness Month, it's crucial to remember that hair loss can often be a symptom of deeper underlying issues, such as autoimmune thyroid disease or exposure to environmental toxins like mold. By raising awareness and seeking a proper diagnosis, individuals affected by alopecia can take steps to regain their health—and in many cases, their hair.

With my additional training in mold illness and a passion for helping patients heal from environmental factors, I strive to bring awareness to these hidden contributors to chronic illness and support those on their journey to better health. If you're struggling with unexplained hair loss, it may be time to consider whether thyroid health or toxic mold could be contributing factors.

Breathing Easy: A Guide to Choosing Air Purifiers for a Healthier Home

Breathing Easy: A Guide to Choosing Air Purifiers for a Healthier Home

by | Jul 20, 2023 | Cardiovascular Health, Environmental Health, Naturopathic Medicine, Prevention, Respiratory Health

Weeks of on and off haze here in Northern Virginia have underscored the importance of clean air for everyone. While air purifiers serve as lifelines during hazardous pollution days, they are also effective in addressing common health concerns such as harmful gases, mold, pollen, dust, bacteria, and viruses. While it is unusual for us in Northern Virginia to experience air quality issues related to wildfires, it is not unlikely to be our last go around with this scenario. Most toxicity from our environment comes from what we breath. According to the National Institutes of Health, an estimated 60% of the health problems caused by environmental factors are due to long-term exposure to urban air pollution. Air purifiers are one proactive way to prevent poor indoor air quality, while optimizing your respiratory, cardiovascular, and cognitive health. If you’ve been procrastinating purchasing an air purifier, I urge you to take some action on this today.

Choosing the right air purifier involves three key steps: determining what you want to remove from your air, assessing the area you want to clean and the desired frequency, and considering the associated costs.

Step One: What do you want removed from your air?

Air purifiers employ different technologies to tackle particulates, gases, or both. Assess the issues you face, whether it's dust, smoke, mold, or chemical odors from paint, off gassing carpets, or car exhaust. The market offers a wide variety of air purifiers, making it crucial to explore all the available options to determine the best fit for your family's needs.

HEPA Air Filters

Advantages: HEPA, short for High-Efficiency Particulate Air, meets strict Department of Energy requirements by removing approximately 99% of airborne particulates larger than 0.3 microns. It effectively filters out mold spores, dust, pollen, pet dander, and flame retardants. For these pollutants, HEPA filters are a suitable choice. However, they might not effectively capture viruses, which are smaller than bacteria.

Disadvantages: HEPA filters may not be efficient in trapping gases, fumes, chemicals, or odors or the lung damaging ultrafine particulate. For comprehensive filtration of these pollutants, a disinfecting filtration system is a better option.

Activated Carbon

Advantages: Also known as activated charcoal, activated carbon is highly effective in adsorbing gases and fumes like formaldehyde and VOCs (Volatile Organic Compounds). It efficiently removes odors from the air, providing a fresher environment.

Disadvantages: Activated carbon filters do not remove particles or germs from indoor air. For comprehensive air purification, a combination system is necessary.

Disinfecting Filtration System

Advantages: The disinfecting filtration system is the most powerful on the market, surpassing HEPA technology by around 40 times in efficiency. It can effectively eliminate particles as tiny as .007 microns, including airborne viruses, molds, and bacteria.

Disadvantages: While highly effective, this system can be costly due to its advanced capabilities. However, the benefits justify the investment in cleaner and healthier air.

UV Filters (Ultra-Violet Filters)

Advantages: UV filters have the capability to eliminate bacteria and viruses by employing UV lights for sterilization.

Disadvantages: UV filters are inadequate for removing large particles like HEPA filters or gases and chemicals like formaldehyde, which can be effectively handled by activated carbon filters.

Ionic Filters

Advantages: Ionic filters release negatively charged ions to electrify dust and dander, making the particles attracted to a positively charged collection plate inside the machine.

Disadvantages: Ionic filters may not be effective as the particles can stick to walls, tabletops, and screens. Additionally, they do not absorb VOCs like formaldehyde, and the introduction of ozone into the home can interact with VOCs to create smog, so I do not recommend these.

Ozone Filters

Advantages: Ozone filters use electrostatic plates and ozone to remove odors and freshen the air.

Disadvantages: Ozone filters are hazardous and pose risks to humans and small pets. Even the Environmental Protection Agency (EPA) cautions against their use, making them unsuitable for anyone, so I do not recommend these.

Step Two: How finely do you need to filter particles?

Particulate matter, also known as particulates, is a major concern with wildfire smoke and a key factor in determining air quality. While larger particles can be seen and are easier to remove due to gravity, fine and ultrafine particles, constituting up to 90% of the story, pose a different challenge. These ultrafine particles can penetrate deep into our lungs and even travel through the bloodstream. Understanding the sizes of specific particulates, such as pollen, mold, bacteria, and viruses, helps determine the level of filtration required.

  • Mold Spores: Typically range from 1 to 100 micrometers in size.
  • Mycotoxins: Mycotoxins are produced by certain molds and are much smaller, usually less than 1 micrometer.
  • Viruses: Vary in size but can be as small as 0.02 micrometers.
  • Bacteria: Usually between 0.5 to 5 micrometers in size.
  • Coarser Particulate Matter (PM10): Particles with a diameter of 10 micrometers or smaller.
  • Fine Particulate Matter (PM2.5): Particles with a diameter of 2.5 micrometers or smaller.
  • Ultrafine Particulate Matter: Particles with a diameter of 0.1 micrometers or smaller.

 Ultrafine particulate matter comes from various sources, including combustion processes (e.g., vehicle exhaust, industrial emissions), wildfires, cooking, and certain indoor activities like smoking or using candles. These particles are so tiny that they can remain suspended in the air for longer periods and can penetrate deep into the respiratory system when inhaled, potentially causing health issues. 

Step Three: Evaluating cleaning capacity and costs

Consider the area you need to clean, factoring in both square footage and ceiling height. Understanding the volume of air in the room is crucial for selecting an appropriately sized air purifier. Additionally, assess the air exchange rate, or how often you want the air completely changed, particularly for asthma and allergy relief. It is generally recommended to achieve three to four air changes per hour.

It's important to note that air quality measurements, such as PM2.5, which quantifies fine and ultrafine particles, can vary across different sites. Consulting multiple sources, AQICN.org, AirNow.gov, PurpleAir, and IQAir, provides a more comprehensive understanding of outdoor air quality.

Cost considerations include the initial purchase price, ongoing power consumption, and filter replacement costs. HEPA units typically range from $200 to $900, with additional expenses for specialized units. Filter replacements costs vary depending on usage, fan speeds, and air quality, averaging between about $70 and $175 per year.

Wirecutter provides a thorough review of air filters that they’ve independently tested for quality, several which are excellent. Top of their list for several years running is the well-engineered Coway Airmega AP-1512HH Mighty, which is a more affordable option than some of the specialized units.

However, given my practice where many of the patients I see have compromised health, aggravated by mold, mycotoxins, and other allergens and ultrafine particulates, I’ve considered the following specialized, high quality air purifiers:

Excellent at filtering out ultrafine particles:

  • Intellipure (down to 0.007, has a unique Disinfecting Filtration System, which I appreciate especially for my patients with mold and mycotoxin illness)
  • IQAir (down to 0.003 microns)
  • AirDoctor (down to 0.003 microns)

Excellent at filtering out VOCs – due to heavy carbon filters:

  • AirPura (18 pounds of carbon)
  • AustinAir (15 pounds of carbon)
  • IQAir GC MultiGas (12 pounds of carbon)
  • IQAir Heath Pro Plus (5 points of carbon)

Clean air is a vital aspect of our well-being, especially during periods of heightened air pollution from wildfires. By selecting the right air purifier tailored to your needs, you can effectively address indoor air quality concerns. Don't delay in taking action to protect yourself and your loved ones. With the challenges posed by recurring smoke, prioritize proactive measures and embrace cleaner air for a healthier home.

Nurturing Health and Indoor Air Quality During Amid Wildfire Smoke

Nurturing Health and Indoor Air Quality During Amid Wildfire Smoke

by | Jul 20, 2023 | Cardiovascular Health, Environmental Health, Naturopathic Medicine, Prevention, Respiratory Health

As a naturopathic doctor and a mom, I understand the deep concern we have for our family's health, especially when wildfire smoke fills the air.  When outdoor is quality is poor, it inevitably enters our homes, becomes trapped, leading to poor indoor air quality. It's important to take proactive steps to protect ourselves and our loved ones. While we cannot control which way the winds blow the smoke, there are actionable steps you can take to nurture your health and maintain clean indoor air during this unpredictable Pyrocene.

1. Stay Informed and Plan Ahead

Stay updated on air quality reports. As air quality measurements can vary between sources, I recommend cross referencing a few sites, such as AQICN.org, AirNow.gov, PurpleAir, and IQAir, which will provide a more comprehensive understanding of air quality. Signing up for alerts from these sites or using their apps and notifications are a helpful way to stay informed. Plan ahead by having essential supplies ready, including air purifiers and N95 masks.

The metrics used in air quality reports can vary depending on the region, but the most common ones include:

  • Air Quality Index (AQI): The AQI is a standardized scale used to communicate the level of air pollution and its associated health risks. It typically ranges from 0 to 500, with lower values indicating better air quality and higher values indicating worse air quality. The AQI is usually categorized into different color-coded levels, ranging from "Good" (0-50) to "Hazardous" (301-500).
  • Particulate Matter (PM2.5 and PM10): These metrics measure the concentration of fine particulate matter (PM2.5) and coarser particulate matter (PM10) in the air. PM2.5 particles are smaller and can penetrate deep into the lungs, while PM10 particles are larger and may be trapped in the upper respiratory tract.
  • Ozone (O3): Ozone is a gas that can be present in the air, particularly on hot and sunny days. While ozone in the upper atmosphere is beneficial in blocking harmful UV rays, ground-level ozone can be harmful when inhaled.
  • Carbon Monoxide (CO): CO is a colorless and odorless gas produced by incomplete combustion of fossil fuels. It can be particularly dangerous in enclosed spaces or areas with heavy traffic.

Regarding N95 masks and exposure guidelines

  • N95 Masks: N95 masks are designed to filter out at least 95% of airborne particles, including PM2.5 and some viruses.  While the are effective in reducing exposure to harmful particulate matter, they will not protect from the harmful gasses.
  • When to Use N95 Masks: It is recommended to wear N95 masks outdoors when the AQI reaches levels of 151 or higher, which falls into the "Unhealthy" category. N95 masks can also be beneficial for individuals with pre-existing respiratory conditions or other health issues, even at lower AQI levels.
  • Avoiding Outdoor Activities: When the AQI reaches levels of 151 or higher, it is best to limit outdoor activities, especially for sensitive groups such as children, the elderly, and individuals with respiratory or heart conditions. At AQI levels of 301 and above (in the "Hazardous" category), it is generally considered unsafe for anyone to stay outdoors for an extended period.

2. Create a Safe Indoor Haven:

Ensure your home provides a clean and healthy environment by following these tips:

  • Consider using a portable air purifier in main living rooms and bedrooms, particularly for vulnerable individuals such as children or those with respiratory conditions. Learn more on how choose the right air purifier for you HERE.
  • Seal windows and doors to minimize smoke infiltration.
  • Use high-efficiency particulate air (HEPA) filters in your HVAC system and air purifiers to capture airborne particles effectively.
  • Keep windows closed and rely on recirculated air during periods of poor outdoor air quality.
  • Clean regularly to minimize dust and allergens, as smoke particles can settle on surfaces. Dust is one of the main harbingers of toxins in our homes! Minimizing it can help to protect not only our lungs, but also our cardiovascular and overall health. 

3. Enhance Respiratory Health Naturally:

Support your respiratory system with natural remedies:

  • Stay hydrated to maintain healthy mucus membranes. Drink plenty of water, herbal teas, and warm broths.
  • Use saline nasal rinses with xylitol or neti pots (with distilled water, saline solution, and xylitol) to keep nasal passages clear. The xylitol helps to keep the nasal tissues moist.
  • Consider respiratory and immune supportive supplements such as vitamin C, quercetin, and N-acetylcysteine (NAC) with your healthcare provider.

4. Optimize Indoor Air Quality:

Take steps to improve indoor air quality even when smoke is not present:

  • Keep indoor plants known for their air-purifying properties, such as snake plants, peace lilies, and spider plants (not ideal for those with mold allergies, but can be an good option for others).
  • Avoid using chemical-laden cleaning products or ‘air fresheners’. Opt for natural alternatives or homemade solutions. One of my favorite all purpose cleaning solutions is 1 part white vinegar to 3 parts water, 1 tsp of free and clear dish detergent, mixed in a reusable spray bottle (the Zepp brand works well).
  • Open windows during periods of improved outdoor air quality to allow fresh air circulation.
  • Reduce indoor pollutant sources like tobacco smoke, scented candles, or excessive use of cooking appliances. If you have a gas range be sure to turn on your vent with every use – this is important for health – especially respiratory health!

5. Maintain a Healthy Lifestyle:

Support overall health and resilience:

  • Eat a nutrient-rich, anti-inflammatory diet with plenty of fruits, vegetables, and omega-3 fatty acids.
  • Engage in regular exercise to support lung health and strengthen immunity.
  • Practice stress-reducing activities like deep breathing, meditation, or yoga to support overall well-being.

When air quality is poor protecting your health and maintaining indoor air quality is essential. By staying informed, creating a safe indoor haven, supporting respiratory health naturally, optimizing indoor air quality, and maintaining a healthy lifestyle, you can help safeguard your family's well-being. Remember, consult with a naturopathic doctor or healthcare professional for personalized advice and recommendations based on your specific needs. Let's prioritize our health and embrace a proactive approach to navigate through these challenging times with resilience and care.

Meet Dr. Sarah Giardenelli, a dedicated naturopathic doctor and acupuncturist with a passion for environmental health in Leesburg, Virginia. With her expertise, you can learn how to enhance your indoor and internal environment, safeguarding yourself from air pollution.

Chocolate, Flaxseeds & Cadmium, Oh My!

Chocolate, Flaxseeds & Cadmium, Oh My!

by | May 4, 2023 | Bone health, Environmental Health, Naturopathic Medicine, Prevention

Two of my favorite foods have been in the news in the past several months, dark chocolate and flaxseeds because sadly, high levels of the toxic metal have been found in many brands. Cadmium transfers to plants from soil at a higher rate than other toxic metals and thus it's ubiquitous in our food supply and there is no safe level of cadmium in food. If you are someone with bones (kidneys or lungs) you should care. I see many women with osteoporosis and in many cases cadmium is an issue. In this article I will share some more information about cadmium, its impact on bone health, and discuss the Consumer Reports on cadmium levels in chocolate and the recent Consumer Labs report cadmium in flaxseed and share which brands have the lowest and highest levels.

For too long, the way we have learned about the ill effects on human health of such toxicants has been through the fall out of pollution. Such is the case with cadmium. In 1968, Toyama Prefecture, Japan, recognized the harmful effects of cadmium on bone when metal mining contaminated the water supply with cadmium, which then spread to the rice grown in the water. Those who ate the rice developed itai-itai (it hurts, it hurts) disease, which caused kidney stones, kidney failure, hypercalciuria, bone pain, and osteoporosis. Cadmium has a long biological half-life and accumulates in kidneys and bones. Because cadmium bioaccumulates in the kidneys, 24-hour urine testing is an accurate way to access body burden (the same isn't true for other heavy metals that bioaccumulate elsewhere in the body). Even a low urinary cadmium level of 0.5 μg/g creatinine increases the risk of osteoporosis, fracture, kidney disease, and various cancers. Safe levels of cadmium in humans have not been established.  

A study in Sweden showed that women with higher cadmium levels, even non-smokers, had a higher risk of osteoporosis. Another study showed that women with urinary cadmium levels between 0.50 and 1.00 μg/g creatinine had a 43% higher risk for hip-BMD-defined osteoporosis compared to those with lower levels. Increasing evidence suggests that in the US female population aged 50 years or older, the primary cause of cadmium-related osteoporosis risk is dietary cadmium rather than tobacco. Another challenge for women is that low iron stores, common in those with heavy periods and multiple pregnancies, can lead to higher cadmium retention, and thus toxicity. While comparable research on bone health has not yet been conducted on men, I have no doubt that men's bones are susceptible as well.  

How Does Cadmium Cause Bone Damage?  

Environmental Toxins are a Major Cause of Bone Loss by Pizzorno and Pizzorno explains how cadmium negatively affects bone metabolism through several mechanisms, with the most significant being the impairment of essential kidney functions and direct damage to osteoblasts. Vitamin D requires two hydroxylations, one in the liver and the other in the kidneys, to produce its most active form, vitamin D3, also known as calcitriol. 1) Cadmium disrupts this process by poisoning the kidney enzyme responsible for the conversion of inactive vitamin D (25-OH-D) to active vitamin D3 (1,25-OH-D3) which then acts on the small intestine, bone, and kidney to regulate calcium and phosphate metabolism. Active vitamin D3 enhances calcium and phosphate absorption from the intestines, promotes bone mineralization, so important for bone health. 2) Cadmium also impairs the kidney's ability to excrete toxins and reabsorb essential molecules and minerals, leading to increased calcium loss in urine. So, if you have high urine calcium, cadmium toxicity could be a potential cause. Moreover, cadmium inhibits the activity of alkaline phosphatase, produced by osteoblasts, which deposits calcium into newly formed bone. 3) Cadmium also decreases bone collagen content by stimulating osteoclast formation and activity, which breaks down the collagen matrix as part of normal remodeling. 4) Finally, cadmium activates toxic response pathways in bone cells, further stimulating osteoclast bone resorption.

Cadmium in Food

The amount of cadmium intake in an average person can be estimated through the Total Diet Study (TDS) and food frequency questionnaires (FFQ). TDS is a food safety monitoring program that collects samples of foodstuffs from supermarkets and retail stores to analyze food additives, pesticide residues, contaminants, and nutrients. This program provides an effective way to determine the contribution of each food item to the total intake of cadmium, with staples that are frequently consumed in large quantities found to have the highest levels of cadmium. TDS data is available for limited countries such as the United States, Australia, Sweden, France, Chile, Spain, Serbia, and Denmark, and indicates that the average consumer's cadmium intake ranges from 8 to 25 μg/day, with staples like rice, potatoes, and wheat contributing 40-60% of the total dietary cadmium intake. Other sources of cadmium include shellfish (ie clams, oysters, mussels, scallops), crustaceans (ie shrimp, lobster, crab), mollusks (ie squid, octopus, snails), offal (organ meats), and spinach. This information was reviewed in a study by Satarug et al. 

The amount of cadmium present in food is not the only factor that determines dietary exposure to the metal; consumption patterns are also important. Some foods, such as organ meats, have high cadmium levels but are not frequently consumed by the general population and therefore do not significantly contribute to overall intake. On the other hand, foods with low cadmium levels but high consumption rates in certain populations can be major sources of cadmium. For example, I and many of my patients consume A LOT of dark chocolate and flaxseed, which is why the recent December 2022 Consumer Reports study findings on cadmium (and lead) in popular brands of dark chocolate bars and the Consumer Labs report on cadmium in flaxseeds stood out to me and prompted me to share this information with you all. 

The Consumer Reports study on lead and cadmium in dark chocolate found several brands to be safer including: Mast Organic Dark Chocolate 80% Cocao, Taza Organic Deliciously Dark Chocolate 80% Cacao; Ghirardelli Intense Dark Chocolate 86% Cacao and Intense Dark Chocolate Twilight Delight 72% Cacao, and Valrhona Abinao Dark Chocolate 85% Cacao. These brands had lower levels of both lead and cadmium compared to other brands tested in the study. In the Consumerlab.com report on flaxseeds, the 365 [Whole Foods Market] Whole Flaxseed was found to be the safest choice for adults and children. Several other brands had either toxic levels of cadmium or levels known to be unsafe for children. However, it's important to note that even these "safer" brands still contain measurable levels of these heavy metals. 

Strategies to Decrease the Body Burden of Cadmium 

We cannot hide from it as cadmium is naturally occurring at low levels in the earth's crust, and as a result, all foods may contain small amounts of cadmium, particularly if the soil is deficient in zinc. However, crops grown with high-phosphate fertilizers typically contain higher levels of cadmium, as these fertilizers can have cadmium amounts of up to 300 mg/kg. Exposure to cadmium can be increased by living close to a smelter or mining operation. 

Per Environmental Toxins are a Major Cause of Bone Loss by Pizzorno and Pizzorno, there are three ways to decrease the body burden of cadmium.

1) The primary strategy for reducing exposure to cadmium is to avoid it. This includes stopping direct and indirect exposure to cigarette smoke, avoiding the consumption of oysters, scallops, and shellfish from coastal waters contaminated with cadmium, and avoiding all foods grown with high-phosphate fertilizers (ie non-organic soy beans). Additionally, air particulates are an under considered source of cadmium (and other toxins) by the average person. Not allowing outdoor shoes to be worn inside the house, dusting regularly, and using air filters such as MERV-12 (preferred) or above in whole house forced-air systems or HEPA filters in frequently used rooms are other ways to minimize exposure. Further, children's jewelry imported from China should be avoided since a 2010 analysis by the US Consumer Product Safety Commission found that 12% of 103 analyzed items contained at least 10% cadmium, with one item containing a staggering 91% cadmium.

2) The second strategy is to ensure adequate consumption of foods rich in trace minerals that compete with cadmium, such as copper, iron, zinc, and selenium.

3) The third strategy is to increase excretion, but this must be done with great care to avoid increasing tissue release of cadmium faster than excretion, which can cause redistribution and further toxic effects. At this point, based on the research of Dr. Stephen Genuis and his team, saunas seem to be the safest and most effective method, though they are slow.

The majority of chronic diseases can now be attributed to toxicant exposure. This quote by my colleague Joseph Pizzorno, ND really strikes home for me as more and more we are seeing how we cannot hide from these environmental toxins:

"Somewhat independent of people’s choices, the things which in the past have been normally considered healthy, or at least neutral, are now becoming significant sources of toxins for people." ~Joseph Pizzorno, ND

All of us are exposed to cadmium and due to dietary, health and genetic differences, some of us have a larger body burden than others. Exploring the body burden of environmental toxicants is an important aspect of prevention. The good news is that naturopathic doctors, like myself, are trained in this and naturopathic medicine has a lot to offer those who are dealing with a high burden of cadmium and other toxicants. If this is an area that you have yet to explore, it's important and I'd love to help. Environmental medicine is a passion of mine, when we can remove even just one burden from a person's toxic load, it is amazing how the body can shift back into balance and so many other areas of health then improve!

Hand Sanitizer: Alcohol-Based or Alcohol-Free?

Hand Sanitizer: Alcohol-Based or Alcohol-Free?

by | Jun 25, 2019 | Environmental Health, Immune Health

I have always been sensitive to both the fumes of alcohol based hand sanitizer and the essential oils in many of the natural based versions. When I transitioned to my current office space, which requires me to use hand sanitizer, I opted for an alcohol free version. However, in doing a podcast with NVSL Magazine Editor-in-Chief about natural immune support for the winter season (I will share the link when this is published), she asked a great question, I paraphrase: “is there really any benefit to these alcohol based hand sanitizers?” I knew from years of working in a medical setting, that they are widely accepted as a replacement to hand washing in most situations based on the research. However, what about these for personal and family usage, do they have any risks? Do they have any benefits?  My gut on this was that of course hand washing is better, but I wanted to check the evidence. I was really surprised by the positive findings of alcohol based hand sanitizers that made me re-examine my resistance to them for personal and family use. For work use I definitely plan to switch over from the non-alcohol based to alcohol based hand sanitizer.

Don’t be fooled by branding

I typically pride myself on being resistant to advertising and researching the ingredients in the personal care products for safety. However, in the case of my hand sanitizer I was duped for sure. How could a product that is fully branded as baby safe and organic, possibly be the opposite of this! In 2016 I was stoked when the FDA changed the status of 19 ingredients that used to be labeled “Generally Recognized as Safe” to “Not Generally Recognized as Safe and Effective”, as manufacturers could not prove their effectiveness (1, 2). This effectively put a ban on these ingredients in hand sanitizers, including chemicals triclosan and triclorocarban. However, these chemicals have been replaced with benzalkonium chloride, benzethonium chloride, and chloroxyleneol that are past due for similar review by the FDA (1). 

We the Public Really are 100,000 Guinea Pigs

Unfortunately, there is evidence that these chemicals are more toxic than triclosan and triclorocarban at dilute levels in at least two animal models (2). Although we can’t really transpose this animal research to risk in humans, it is a shameful that proper research hasn’t been done on many of these chemicals that are ubiquitous in personal care products and that the FDA leaves the margin of proof of safety and evidence of benefit, largely to the manufactures and outside researchers to prove. Even though we are all exposed to these chemicals in one way or another, the American government doesn’t require pre-market testing or health studies in personal care products (3). In other words, we the public really are 100,000 guinea pigs. There are resources I appreciate, specifically, Environmental Working Group’s Skin Deep database, that makes the safety data on chemicals in these products readily available to the public (3). This is a great resource to help make informed decisions on what personal care products are thought to be most safe for you, your family and the environment. 

My surprise!

Recent clinical research was summarized in the Journal of the American Medical Association showed a significant reduction in respiratory track infections in day care settings where the staff, children and parents used alcohol based hand sanitizers when compared side by side to hand washing. In fact, there was found to be 23% fewer respiratory infections and 30% fewer antibiotic prescriptions (4). This is pretty remarkable and has helped me transition my position alcohol based hand sanitizers. Likewise, another study done on alcohol based hand sanitizer demonstrated that home use can significantly reduce the transfer of a viruses (5). By and large alcohol based hand sanitizers have been shown to be effective and safe (6).         `

Evidence Informed Decision

Consequently, after considering the questions and evidence of alcohol based hand sanitizers for personal and home use, I think it is probably better to use them, especially since they so significantly reduce the risk of repeated courses of antibiotics, which can have adverse effects. Hand-washing in the home setting is perfectly fine, but if out in about in a public setting, there is pretty significant benefit and no evidence of harm from using these alcohol based hand sanitizers. I definitely recommend the alcohol based hand rubs that have either no added fragrance or that use essential oil added for fragrance instead of the synthetic fragrance that has its own safety concerns.

Are We Too Clean?

On the other hand, there is discussion to be had about our culture being overly sanitized and this cleanliness compromising our immune health. Some regular exposure to germs helps to build the immune system. I think this overly sanitized issue stems from not letting kids be kids and play in the dirt, social isolation/ children not being allowed to play with other children or animals, or avoiding public settings out of "fear of germs", and the overuse of sanitizing cleaning agents in the home. Balance needs to be had, especially in between cold and flu season or when around those who are immune compromised, such as when visiting hospitals. I think we need to have some balance and be mindful of exposures. Probably now after looking into this topic further I will not be so shy about applying a basic alcohol based hand sanitizer to my little one's hands after he is done playing in a public setting, he'll still have gotten plenty of exposure to microbes, just by playing in that setting.
