Should You Be Worried About Toxic Heavy Metals?
FAQs
You’ve likely come across the term “toxic heavy metals” in the news or online, but what do these mysterious-sounding substances mean for your health? More and more people are curious about how these naturally-occurring elements, like arsenic, lead and mercury, get into their food, and how heavy metal content in food may impact their health. In this article, we’ll break down what toxic heavy metals are, where they’re commonly found, and whether they should cause concern.

According to theNational Institutes of Health, the most common metals that cause toxicity include arsenic, cadmium, chromium, lead and mercury. Toxic heavy metals can potentially harm your health at high levels of exposure. Over time, they can accumulate in your body, leading tovarious adverse effects, such as abdominal pain, chills, fatigue, diarrhea, nausea and vomiting.
These metals are classified as toxic due to their potential to causesevere health issues, ranging from neurological disorders to organ damage. According to a 2021 study inMolecules, heavy metals can enter your body through various routes, such as contaminated water, food, air pollution or occupational exposure.

One common source of heavy metal exposure is drinking water, as certain areas may have water supplies contaminated with metals such as lead, arsenic or mercury. Additionally, toxic metals can enter the food chain through contaminated soil, pesticides or industrial processes. According to a 2020 study published inHeliyon, environmental pollutants (e.g., air pollution from industrial emissions or vehicle exhaust) can increase your toxic heavy metal exposure.
“Heavy metals can and do exist in some foods (from the soil, water and air where they’re grown), but it isn’t something that individuals need to be overly stressed about,” Sarah Schlichter, M.P.H., RDN, a registered dietitian atBucket List Tummy, tellsEatingWell. “Furthermore, the presence of a contaminant doesn’t mean a food is unsafe to eat. People can be educated to make informed decisions about limiting toxic heavy metal exposure through their diets and environment.”
While it’s essential to be aware of toxic heavy metals in the environment, there’s no need to panic or live in constant worry. The reality is that many aspects of the environment, such as city drinking water or air pollution, are beyond your immediate control.
However, there are practical steps you can take to reduce your exposure risk. One approach is to diversify your diet and eat a wide variety of foods. Research shows that certain foods, likericeandfish, can be more likely to contain heavy metals. To help enjoy these foods safely, consider occasionally swapping rice for alternatives like quinoa, bulgur, couscous or cauliflower rice, and choose fish with lower mercury levels, such as salmon or sardines. Additionally,washing and peeling fruits and vegetablesand sourcing them from reputable producers or local farmers can help minimize potential exposure.
The Bottom Line
While metals like mercury, lead and arsenic can be harmful at high levels, they shouldn’t keep you up at night. These heavy metals are found in various sources, including water, food and the environment. Fortunately, there are practical steps you can take to reduce your exposure risk, such as diversifying your diet, choosing foods with lower heavy metal content and sourcing produce responsibly.
Frequently Asked QuestionsWhile symptoms can vary from person to person, common symptoms ofheavy metal toxicitymay include fatigue, brain fog, digestive issues, muscle weakness and headaches.“Chronic and long-term exposure can have damaging health effects, such as gastrointestinal disorders, organ damage, an increased risk for cancer and the progression of neurological diseases, such as Parkinson’s and Alzheimer’s,” says Schlichter.Heavy metal testingtypically involves various methods, such as blood, urine, hair and fingernail tests. These tests help determine the presence and levels of specific heavy metals in the body. If you suspect heavy metal exposure or are experiencing related symptoms, visit your health care provider, who can guide you in choosing the appropriate testing method.
