Metals for health -

We need small amounts of some metals for our bodies to function properly. For example, minerals like iron and zinc are essential to our health.

Metal toxicity -

However, depending on the amount of metals in the body, these can become toxic. Not to mention, certain metals such as mercury or lead are highly poisonous.

Absorption -

Heavy metals typically enter the body through the skin, or they can be ingested and inhaled. When this happens, heavy metal toxicity can occur, and you might need to detox.

What exactly is a heavy metal? -

A heavy metal is something that has metallic elements that have a high density in comparison with water. They are found naturally in the environment.

Where are they found? -

As well as being found in the environment, they're also present in things we consume, such as certain foods, medicines, and supplements.

Where are they found? -

But these aren't the only sources. Chemicals used in industry and farming sometimes contain heavy metals that inevitably end up in our soil, air, and water.

Examples of heavy metals -

Example of heavy metals include: arsenic, cadmium, chromium, copper, iron, lead, manganese, mercury, nickel, selenium, thallium, and zinc.

Symptoms of toxicity -

It can be hard to diagnose heavy metal toxicity, as it generally manifests in symptoms that are also common to other illnesses.

Symptoms of toxicity -

Signs include shortness of breath, tingling in the hands and feet, muscle weakness, and even more serious complications like heart arrhythmias and memory loss.

Symptoms of toxicity -

Other, more benign symptoms that could be mistaken for something else include nausea, gastrointestinal upset, vomiting, and diarrhea.

Diagnosing heavy metal toxicity -

Your healthcare provider will order a heavy metal toxicity test, using one or multiple methods, if they suspect heavy metal poisoning.

Fish and shellfish -

Sometimes, it's asked that you don't consume fish or shellfish up to 48 hours before testing. This is because these foods often contain the metal mercury.

Testing -

Urine, blood, and hair sample tests are used to measure the levels of heavy metals in the body. Sometimes metals can be present in high levels that aren't necessarily toxic.

Heavy metals in blood -

If there are high levels of metals in your blood, but you aren't suffering from toxicity, you might be asked to reduce/limit your contact with heavy metals to help bring down your levels.

Heavy metals in tissue -

Conversely, if your test shows low levels but you are still suffering from symptoms, it's possible that the metals are being stored in your tissues. Blood tests don't always give the clearest picture.

Biomonitoring -

If you have a job that regularly exposes you to heavy metals, you might be tested as part of ongoing biomonitoring. Testing is usually only recommended if you've had known exposure to a toxic metal.

Chelation therapy -

Chelation therapy is one medically-administered way to detox from heavy metals. It involves taking medication or receiving an injection that helps remove the metals from the body.

Chelation therapy -

Sometimes chelation therapy is administered through a drip/IV (intravenous line). However, there are severe dangers associated with chelation therapy, so it's only for very serious cases.

A wellness trend? -

It's not so common to be exposed to high levels of heavy metals, but the idea that chronic, low-grade exposure can lead to a build-up (that would benefit from a detox) has gained a following in wellness circles.

Foods to avoid -

In order to reduce your potential exposure to heavy metals via food, there are choices you can make about what to consume. Rice, and in particular brown rice, has been shown to contain arsenic. Long-living fish are more likely to contain mercury. Non-organic foods (that have been exposed to pesticides) are more likely to contain a higher heavy metal load, while alcohol slows down the liver's ability to detox things from the body.

Antioxidant-rich foods -

Fruits and vegetables that are antioxidant-rich, with a high vitamin C content, can help protect the organs from the damage caused by heavy metals.

Phytonutrients -

Phytochemicals contained in some fruits and vegetables have beneficial effects against toxicity. Examples of these include garlic, ginger, green tea, grapes, tomatoes, and berries.

Spirulina and cilantro -

Atlantic dulse and spirulina are claimed to help alleviate toxicity. Cilantro (coriander) is one of the best plants for detoxifying, supporting the liver's removal of metals such as mercury and lead.

Supplements -

There are certain supplements—such as glutathione, ALA, or selenium—that are supposed to support the body's detox of heavy metals. But you shouldn't self-prescribe, always talk to a provider first.

Probiotics -

There is some research to show that probiotics bind to heavy metals such as aluminum, arsenic, cadmium, and lead, assisting with their elimination via the bowels.

© Shutterstock

Exercise -

Sweating is one of the best, fool-proof ways to help the body detoxify. There is some research to suggest that exercise-induced sweating can help the body eliminate heavy metals.

© Shutterstock

Excretion -

Another way the body detoxes is via the kidneys. Although it's considered not to be as effective as excretion through sweating, staying well hydrated will help to flush toxins from the body in real time.

Aluminium pans -

If you're worried about your potential exposure to heavy metals in your household, one of the first places to begin is by replacing aluminum and non-stick pans with stainless steel, ceramic, glass, or cast iron alternatives.

Get your water supply tested -

If your home water supply is from a natural spring or you're worried about aging pipes in your residence, you can test the water in your home to check for heavy metal content.
