A famous doctor revealed on social media that he does not use plastic water bottles, and urges everyone to follow his advice and avoid drinking water this way.
Doctor Saurabh Sethi, who lives in California, warned that these products contain a lot of toxic nanoplastics that settle in the body and are linked to cancer and infertility.
He pointed to a study published earlier this year that found that the average bottle of water sold in the United States contains 240,000 of these molecules.
In a video clip on TikTok that has been viewed more than half a million times, the gastroenterologist begins by saying: “Stop using plastic water bottles. These particles have the ability to penetrate human cells and enter the bloodstream and major organs.”
Instead, he urged his followers to use reusable stainless steel containers for water consumption.
Dr. Sethi said that drinking from a plastic bottle during hot days is most harmful. “The heat will cause more microplastics to be released into your water bottle,” he added.
But the video left some viewers with more questions than answers, as many pointed out that tap water also contains harmful toxins linked to health problems.
Reusable containers, such as stainless steel cups, have also been shown to contain metals linked to various diseases.
Concerns about microplastics have increased in recent years. A study published in 2023 used biological models and biomarkers to determine the toxic effects of nanoparticles when consumed.
The researchers found that plastic particles can cause cell death, produce oxidative stress, damage DNA, and stimulate inflammatory responses, processes associated with tumorigenesis.
Other studies have found that exposure to small particles may lead to significant congenital heart defects that impair heart function in chicken fetuses.
But effects in humans are based on laboratory and animal studies without direct evidence. The Food and Drug Administration (FDA) said it's too early to panic about bottled water.
