Every cell in your body contains structures that work tirelessly to protect your DNA and fight off the aging process. But, if you’re not careful, a common pollutant might disrupt this protection system and cause you to age before your time.
A study at the Milken Institute School of Public Health at George Washington University has shown that the heavy metal cadmium can shorten telomeres, which are the sections of DNA in every cell that protect your genetic material from deterioration. As your telomeres shorten, your risk for diabetes, heart disease, and other age-related health issues increases.
Cadmium’s Connection to Premature Aging
Researcher Ami Zota and her team found a strong association between exposure to even low levels of cadmium and telomere shortening. The study’s findings indicate that cadmium exposure can result in the premature aging of cells. This discovery adds to mounting evidence that the heavy metal can enter the bloodstream, leading to kidney disease and other health problems.
The World Health Organization (WHO) has recognized cadmium as a “major public health concern.” In a report, the WHO warns that cadmium is linked to respiratory issues, cardiovascular difficulties, and cancer.
Where is Cadmium Found?
Cigarette smoke is the most common source of cadmium exposure, but factories and other industrial facilities can also emit the heavy metal. Additionally, you might be exposed to cadmium through contact with contaminated soil or consumption of vegetables grown in polluted soil.
Zota notes that the study found people with the highest cadmium exposure had cells that appeared, on average, 11 years older than their actual age. This alarming discovery highlights the potential dangers of exposure to cadmium, even at low levels.
To better understand the impact of cadmium on our health, let’s delve deeper into cadmium’s sources, effects, and how to minimize exposure.
Cadmium’s Environmental Impact
As a naturally occurring element, cadmium is released into the environment in various ways. Forest fires, volcanoes, and the weathering of rocks are natural sources of cadmium release.
Human activities, however, have dramatically increased cadmium emissions. The mining and smelting of metals, burning of fossil fuels, and incineration of waste materials all release cadmium into the environment. Consequently, cadmium can contaminate air, soil, and water, posing potential hazards to human health.
Health Effects of Cadmium Exposure
Long-term exposure to cadmium can lead to various health problems. Some of the most significant issues associated with cadmium exposure include:
- Kidney damage: Cadmium can build up in the kidneys, causing kidney disease and, eventually, kidney failure.
-
Bone damage: Cadmium exposure can lead to the weakening of bones, making them more susceptible to fractures.
-
Respiratory issues: Inhaling cadmium can cause lung irritation and inflammation, resulting in symptoms such as coughing, chest pain, and shortness of breath.
-
Cardiovascular problems: Cadmium has been linked to an increased risk of heart disease, hypertension, and stroke.
-
Cancer: Studies have shown a connection between cadmium exposure and an elevated risk of lung, prostate, and other types of cancer.
Reducing Your Exposure to Cadmium
To minimize your exposure to cadmium, consider the following precautions:
- Quit smoking: As mentioned earlier, cigarette smoke is a significant source of cadmium exposure. Quitting smoking will not only reduce your cadmium intake but also provide numerous other health benefits.
-
Test your home: If you live near an industrial area or suspect your soil may contain cadmium, have it tested. You may need to prevent your children from playing in contaminated areas or mitigate the issue by adjusting your landscaping.
-
Drink filtered water: To ensure your drinking water is free of cadmium, use a water filter that has been certified for cadmium reduction.
-
Eat a nutritious diet: Eating a diet rich in essential nutrients can help reduce the absorption of cadmium in your body. Focus on consuming foods high in calcium, iron, and zinc, as these nutrients can help counteract the effects of cadmium exposure.
-
Be cautious with seafood: Some fish, particularly shellfish, can contain high levels of cadmium. To reduce your risk, choose fish from responsible and sustainable sources and be mindful of your seafood intake.
By understanding the risks associated with cadmium exposure and taking the necessary precautions, you can help protect your health and preserve the integrity of your cells, keeping you young and fit for years to come.
