Brewing tea removes harmful toxins from water, study finds

Tea has long been celebrated for its numerous health benefits, but a recent study from Northwestern University in Illinois has revealed yet another reason to enjoy a cup of your favorite brew. According to the research, the process of brewing tea can actually help remove toxic heavy metals from drinking water.

Lead and cadmium, two harmful heavy metals commonly found in water sources, are absorbed by the tea leaves during the brewing process, effectively preventing them from entering the water. This means that simply brewing a cup of tea for three to five minutes can remove approximately 15% of lead from your drinking water.

Lead contamination in drinking water is a serious issue, especially for children, as it can have detrimental effects on their health. The researchers found that different types of tea, tea bags, and brewing methods all played a role in how effectively heavy metals were absorbed. Surprisingly, even wood-derived tea bags were found to be effective in removing these toxins.

The longer tea is brewed, the more reduction in metal content, making overnight iced tea a particularly effective method for remediation. The researchers also noted that tea leaves with a high surface area, such as those that have been processed or ground, are more efficient at absorbing metals.

While the study’s findings are promising, the researchers caution against relying solely on tea to clean your water. It is still important to use certified filters that are specifically designed to remove heavy metals from drinking water. Schools and childcare centers, in particular, should invest in lead-filtering water stations and replace lead pipes to ensure the safety of their students.

Overall, the study highlights the potential health benefits of incorporating tea into your daily routine. Not only does tea offer a myriad of health advantages, but it may also help reduce exposure to harmful toxins in drinking water. So, next time you brew a cup of tea, know that you’re not just getting a delicious and soothing beverage – you’re also taking a small step towards better health.
