Toxins can be found in our food in many and unpredictable ways. Mercury in fish. Arsenic in rice. Even mixed juices contain toxins. Fish that are higher on the food chain, that grow slower, and live longer accumulate more toxins. Safer fish choices include clams, cod, salmon, and tilapia. Bonus points for sardines because they are high in selenium.

HEAVY METALS IN FOODS AND BEVERAGES

Heavy metal toxicity is directly related to their accumulation in food. High amounts of these elements generate numerous health issues. Therefore, consumers must choose their food sources carefully. Metals like lead, cadmium, and arsenic are the main elements with high potential health risks. According to the analyzed studies, the highest value for cadmium was registered in lettuce cultivated in Romania; excessive amounts of lead were found in apple samples from Ukraine and Kosovo, but also in lettuce or red potatoes from Romania; and arsenic presented alarming values in lettuce from Florida.

TOXIC AND ESSENTIAL ELEMENTS IN RICE AND OTHER GRAINS

White rice from Thailand, India, and Italy showed higher median concentrations of toxic metal such as As, Pb, and Cd compared to white rice from the US. Lead and Cd concentrations did not exceed the codex standards; however, Arsenic (As) concentrations in brown rice and one white rice from US exceeded the codex standards.

CONTAMINENTS IN FISH AND CLAMS IN SINCLAIR AND DYES INLET 1992

Concentrations of several metals in fish from Sinclair and Dyes Inlets exceeded those found in comparable studies in the same area and were equivalent or higher than fish from other urban bays. Most importantly, mercury in fish in the present study (0.4 mg/kg) approached the FDA action limit of 1 mg/kg. The California limit is 0.5 mg/kg.

SEPARATING THE EMPIRICAL WHEAT FROM THE PSEUDOSCIENTIFIC CHAFF: A CRITICAL REVIEW OF THE LITERATURE SURROUNDING GLYPHOSATE, DYSBIOSIS AND WHEAT-SENSITIVITY
​
While the current review focused on the agricultural practice of desiccating wheat, it should be noted that many crops, including legumes, corn, and soy, have been shown to contain high glyphosate residues due to desiccation and the advancement of glyphosate-resistant crops. Eliminating wheat from one’s diet does not guarantee the elimination of glyphosate exposure. However, wheat products have been shown in independent testing to contain higher residues post-processing and make up a significant portion of the average North American’s dietary glyphosate exposure.

It is really hard to avoid glyphosate and pesticides. However, USDA Organic certified products must be grown or produced without the use of synthetic herbicides, pesticides, or fertilizers. This includes glyphosate. Can there still be glyphosate in USDA Organic flours and foods? Yes. We don't grow our food in a bubble and things can waft, drift, or otherwise meander from a non-organic farm over to an organic farm. Organic foods should have less glyphosate, so it is something to consider.

Fires release particulates and heavy metals into the air. Trees absorb heavy metals, but when homes and other man made structures burn, that's when the pollution is the worst.

METAL TOXIN THREAT IN WILDLAND FIRES DETERMINED BY GEOLOGY AND FIRE SEVERITY

Accentuated by climate change, catastrophic wildfires are a growing, distributed global public health risk from inhalation of smoke and dust. Underrecognized, however, are the health threats arising from fire-altered toxic metals natural to soils and plants. Here, we demonstrate that high temperatures during California wildfires catalyzed widespread transformation of chromium to its carcinogenic form in soil and ash, as hexavalent chromium, particularly in areas with metal-rich geologies (e.g., serpentinite). In wildfire ash, we observed dangerous levels (327-13,100 µg kg−1) of reactive hexavalent chromium in wind-dispersible particulates.

You may want to test the water coming out of your faucet and the dirt that your are digging in. While your water provider rigorously tests the water going to your house. They don't test what comes out of your faucet. As we researched in this other post, there are ways for your water to get contaminated on the home stretch. Air pollution like the Tacoma Plume we researched in this post, may have contaminated your soil.

ARE SOME METALS IN TATTOO INKS HARMFUL TO HEALTH?
In this study, amounts of some metals were measured in samples taken from the market, and some of the amounts were found to be above the concentrations specified in the guidelines and in amounts that could pose a risk to public health. Reliable results were obtained by validating the method and choosing the best acid combination for the preparation of the samples.
Many people may not be aware that they can get harmful effects by the chemicals of tattoo inks. We believe that it will be beneficial to make the results open to public and to inform tattoo artists and people who have tattooed, albeit limited, when deciding to purchase tattoo ink.

There are so many great vitamins and minerals in our fruits and vegetables. The more you dig into it the more you learn that the garden is a pharmacy. Your health is built on your diet.

DIETARY STRATEGIES FOR THE TREATMENT OF CADMIUM AND LEAD TOXICITY
​
We recommend that people who are at risk of exposure to toxic metals ensure a sufficient intake of essential elements and vitamins and enhance their consumption of vegetables and fruit.  Some edible plants, such as tomatoes (rich in iron, calcium, selenium, zinc, vitamins B and C, quercetin and naringenin), berries (rich in essential elements, vitamin C, anthocyanin and catechin), onions (rich in selenium, quercetin and vitamins B and C), garlics (rich in sulphur-containing compounds, essential elements and vitamins C and E) and grapes (rich in vitamins, essential elements and anthocyanin) are of special importance as natural antagonists to Cadmium and Lead toxicity and should be consumed on a regular basis.

A STUDY ON THE EFFECT OF GARLIC TO THE HEAVY METAL POISONING OF RAT

When garlic (Allium sativum) was administered to rat per os simultaneously with cadmium, methylmercury and phenylmercury to detect the protective effect against the heavy metal poisoning, accumulation of heavy metals in liver, kidneys, bone and testes were decreased, and histopathological damages and the inhibition of serum alkaline phosphatase activities by heavy metals were reduced. The protective effect of garlic was superior to those of 2,3 dimercapto-1-propanol (BAL) and D-penicillamine (PEN), and nearly similar to those of 2,3-dimercaptosuccinic acid (DMSA) and N-acetyl-DL-penicillamine (APEN), the current remedies, while garlic was not effective as a curative agent for heavy metal poisoning.

Certain fibers such as wheat bran and pectin act as a shield. They protect our gut microbiome from the negative changes from heavy metal exposure. They are especially helpful guarding us from arsenic and cadmium.

SPECIFIC DIETARY FIBERS PREVENT HEAVY METAL DISRUPTION OF THE HUMAN GUT MICROBIOTA IN VITRO

This study aimed to investigate the effects of different heavy metals (As, Cd and Hg in different concentrations) on gut microbiota in the presence and absence of different dietary fibers that included fructooligosaccharides, pectin, resistant starch, and wheat bran. We observed that whereas heavy metals impaired fiber fermentation outcomes for some fiber types, the presence of fibers generally protected gut microbial communities from heavy metal-induced changes, especially for Arsenic and Cadmium. Notably, the protective effects varied depending on fiber types, and heavy metal type and concentration and were overall stronger for wheat bran and pectin than other fiber types.

Should you be testing to find out if you have too many heavy metals in your body before you do something about it? Maybe not. Testing methods need to evolve to be more reliable and cost effective. Results need to be carefully interpreted. Caution needs to be taken to ensure that the stress from diagnosis and resulting treatments don't do more harm than good.

The cost of treating heavy metal toxicity (Zeolite Clinoptilolite and Chlorella) is less expensive than testing for the presence of stored heavy metals in your body. So when it feels safe to assume that most people have exposure to toxins, it may be reasonable to treat toxicity without the burden of proving the source of chronic health problems.

DOC, CAN YOU TEST ME FOR "TOXIC METALS"? CHALLENGES OF TESTING FOR TOXICANTS IN PATIENTS WITH ENVIRONMENTAL CONCERNS

Targeted environmental laboratory testing may be warranted in a patient based on findings of a thorough environmental history and physical exam, but should not include a “shotgun” approach for a variety of toxicants.
Acting on the results of inappropriate tests may lead to significant health-related costs due to associated treatments and procedures, in pediatric patients this may be particularly problematic. 
“Provocation” urine testing is an inappropriate environmental test that measures urinary excretion of metals after administration of a chelating agent such as 2,3-dimercaptosuccinic acid (DMSA; succimer). These tests offer no reliable diagnostic value, as there are no validated reference ranges for “provoked” urine metals in children; further, there are potential side effects from chelating agents.
Further, if urine metal tests are ordered incorrectly, the results can be misinterpreted and lead to stress in the family or misdiagnosis of toxicity. If a provider is concerned about arsenic toxicity, the urinary arsenic test should be ordered with “speciation” (rather than total arsenic) to determine if the arsenic is the “organic” or “inorganic” form. 
Hair analysis for elements (including metals) is increasing in popularity and can lead to potentially misleading and/or spurious results. These tests cannot distinguish if the metal is biologically deposited within the hair or externally deposited on the hair’s surface from sources such as air pollution, dust, or hair treatments.

AMERICAN COLLEGE OF MEDICAL TOXICOLOGY POSITION STATEMENT ON POST-CHELATOR CHALLENGE URINARY METAL TESTING

Unfortunately, the practice of post-challenge urine metal testing and its application to assessment of metal poisoning often leads to unwarranted and prolonged oral and/or intravenous administration of chelating agents, in response to the results of serial post-challenge testing that remain elevated above non-challenge reference values. Chelation therapy based on such laboratory values, in addition to being of no benefit to patient outcome, may actually prove harmful; catastrophic outcomes such as acute fatal hypocalcemia have been reported following the improper use of a chelating agent, edetate disodium (Na2–EDTA). In addition, the safer formulation of this agent, CaNa2–EDTA, has been demonstrated to increase urinary excretion of essential minerals such as iron, copper, and zinc.

HEAVY METALS IN FISH AND ITS ASSOCIATION WITH AUTOIMMUNITY IN THE DEVELOPMENT OF JUVENILE IDIOPATHIC ARTHRITIS: A PROSPECTIVE BIRTH COHORT STUDY

Moderate exposure to heavy metals, associated with fish consumption, during pregnancy and early childhood may cause effects on the immune system of the offspring, resulting in ANA positivity and JIA.

Aluminium is a potent stimulator of the immune system, which is the very reason it is used as an adjuvant. In the absence of Al most vaccinations fail to launch an adequate immune response. Pro-inflammatory cytokines, such as interleukin-1 and interleukin-6, are needed for adequate stimulation of antibody-producing B-cells. These cytokines are induced by Al adjuvants in vaccines. Our results showed that cord blood aluminium does not correlate with fish consumption, but correlate with development of JIA. We have no explanation for this results. One can speculate about the source of the aluminium that leads to higher cord blood levels of Aluminium in JIA patients. Certain families may have been cooking in aluminium containers more often than other families. Another source could be intake of aluminium from foods (other than fish) or consumed by using aluminium-containing pharmaceuticals.

METALS AS A COMMON TRIGGER OF INFLAMMATION RESULTING IN NON-SPECIFIC SYMPTOMS: DIAGNOSIS AND TREATMENT

In this study, reduction of inflammation-causing metals resulted in an alleviation of symptoms and long-term health improvement. The decrease of metal-specific lymphocyte responses in vitro after removal of sensitizing metals supports the clinical relevance of these findings. 

In addition to their well-known toxic effects, heavy and transition metals might function as immunologically active haptens as well as possess potent adjuvant inflammatory potential. In susceptible patients, chronic low dose exposure to metals may trigger inflammation and exacerbate already existing diseases. Cytokine release with deregulate the HPA axis and trigger non-specific symptoms, including profound fatigue and joint pain. In patients suffering from CFS, fibromyalgia or ASIA, laboratory markers of metal allergy, such as metal-specific memory lymphocytes, should always be measured. The proposed treatment protocol follows the standard procedure used in allergology and dermatology: namely, avoidance of exposure to sensitizing agent(s).

Lastly, it is of utmost importance to increase awareness among health professionals regarding the risk for systemic side effects caused by metal exposure in immunologically sensitized patients.

Heavy metals impact the function of our brains in ways that mimic or exacerbate autism spectrum disorders and ADHD.

MECHANISMS ASSOCIATED WITH COGNITIVE AND BEHAVIORAL IMPAIRMENT INDUCED BY ARSENIC EXPOSURE

Inorganic and methylated arsenic species can accumulate in different tissues including the brain, in which the accumulation is region-specific. Perinatal exposure to arsenic leads to long-term behavioral, cognitive, and motor deficits. The neurotoxic mechanisms of arsenic include exacerbated oxidative stress, mitochondrial dysfunction, and impaired synaptic activity, which drive cell damage and, ultimately, cell death.

ASSOCIATION BETWEEN HEAVY METAL EXPOSURE AND PARKINSON'S DISEASE: A REVIEW OF THE MECHANISMS RELATED TO OXIDATIVE STRESS

Parkinson’s disease (PD) is a gradually progressing neurodegenerative condition that is marked by a loss of motor coordination along with non-motor features. Although the precise cause of PD has not been determined, the disease condition is mostly associated with the exposure to environmental toxins, such as metals, and their abnormal accumulation in the brain. Heavy metals, such as iron (Fe), mercury (Hg), manganese (Mn), copper (Cu), and lead (Pb), have been linked to PD and contribute to its progression.

METALS AND NEURODEGENERATION

Once metals have accumulated in the nervous system, oxidative stress, mitochondrial dysfunction, and protein misfolding are the most common deficits associated with metal-induced toxicity. Once injured, neurons have to expend greater energy to synthesize neurotransmitters and maintain homeostasis. The increased burden combined with the neurotoxicity may lead to neuronal death. When some neurons are lost, the job has to be passed on to other neurons, initiating a vicious cycle of toxicity. Given that the nervous system does not regenerate as well as other systems do, the neurodegeneration and impairments usually become progressive with age, as typically seen in Alzheimer's disease and Parkinson's disease.
