Tea Leaves Can Steep Away Lead, Study Finds
Tea leaves pull heavy metals from water, significantly lowering the amount of lead and other dangerous compounds that people may be unknowingly drinking, a new study found.
Recent research has highlighted potential applications for used tea leaves, from biofuels to gluten-free cookies. But the new study shows a public health benefit from something that countless people are already doing. About five billion cups of tea are consumed each day around the world, according to one estimate.
“You can see the implications,” said Vinayak Dravid, a materials scientist at Northwestern and an author of the study, which was published this week. “How often do we touch billions of people?”
In many countries, the water used to steep tea is contaminated with lead from aging pipes. In the United States, nine million homes get their water through pipes that contain lead, according to the Environmental Protection Agency. Lead is especially dangerous to children. Exposure can lead to developmental delays and behavioral issues.
Dr. Dravid and his team tested how different types of tea — black, white, oolong, green, rooibos, herbal, loose leaf and plain old Lipton — behaved in water with varying amounts of lead.
The tea was then allowed to steep for variable periods of time. Afterward, the scientists measured how much lead remained in the water.
Compounds called catechins in tea leaves act like “little Velcro” hooks to which lead molecules latch, said Michelle Francl, a chemist at Bryn Mawr College and the author of a book on the chemistry of tea. Dr. Francl also said that the “ridges and valleys” of the tea leaves provided the necessary surface area for that interaction.
While those properties have been known for some time, Dr. Dravid and his colleagues were the first to look at the lead-detoxifying powers of a single cup of tea. They found that black tea leaves became wrinkled after roasting and were thus best equipped to absorb heavy metals.
“Green tea and black tea had fairly equivalent amounts of metal absorbed,” said another author, Benjamin Shindel, who was a doctoral candidate at Northwestern while working on the study.
White tea, on the other hand, undergoes a much more gentle preparation. Its leaves remain smooth, offering less surface area from which to draw heavy metals from water. Herbal tea enthusiasts may be disappointed to learn that chamomile tea does a poor job of heavy-metal filtering, too, probably because it is made with chamomile flowers, not tea leaves.
Still, these distinctions between different types of tea were not the most relevant factor. “It’s much more important how long you’re brewing the tea for,” Dr. Shindel said.
The researchers found that steeping a cup of black tea for five minutes could remove 15 percent of lead from the water, which is helpful, but there is “no safe level” of lead exposure, according to the E.P.A.
“With lead and other contaminants, any decrease is meaningful to some extent, especially if you have a lack of resources or infrastructure that would already remediate some of these problem materials,” said Caroline Harms, who was an undergraduate student of Dr. Dravid at Northwestern while working on the study.
The longer the steeping time, however, the more bitter the resulting tea. Last year, Dr. Francl caused a minor international scandal by suggesting that adding salt to tea could mitigate its bitterness. But even that controversial chemistry hack has its limits. “It’s not really drinkable after 10 minutes of steeping tea, and no amount of salt is going to help that,” she said.
Some samples in the study had to be steeped for 24 hours, which would render the tea undrinkable.
The study’s authors said they were less motivated to make public health prescriptions for policymakers than to study a hidden benefit of a global habit.
The researchers estimated that a country where people drank large amounts of tea would have about 3 percent less lead ingestion from the water supply than a (hypothetical) identical country that did not drink any tea.
“How wonderful,” said Henrietta Lovell, the founder of the Rare Tea Company. Ms. Lovell, who supplies teas to exclusive restaurants, pointed out that tea had been used in China for medicinal purposes for thousands of years. “The more I learn about tea, the more fabulous and fascinating it becomes,” Ms. Lovell said.
Dr. Francl believes that the new findings could eventually pave the way to a scalable method of making sure people aren’t ingesting heavy metals. “Given that clean water is such a global issue,” she said, “if there was a way to take this proof of concept and tweak it to produce potable water at the end, that would be pretty good.”

Relationship coach blames Oprah for pushing family estrangement ‘for decades’
NEWYou can now listen to Fox News articles!
Oprah Winfrey is shining a light on family estrangement, which she calls “one of the fastest-growing cultural shifts of our time” — but one expert says the media mogul helped fuel that very culture.
“A Cornell University study now shows that almost one-third of Americans are actively estranged from a family member,” Winfrey said on a recent episode of “The Oprah Podcast,” referring to adult children going “no-contact” with parents, siblings or entire family systems.
Winfrey said the trend is a “silent epidemic” that can be especially relevant during the holidays.
ONE TOXIC BEHAVIOR KILLS RELATIONSHIPS, LEADING HAPPINESS EXPERT WARNS
But family and relationship coach Tania Khazaal, who focuses on fighting “cutoff culture,” took to social media to criticize Winfrey for acting as if the estrangement crisis appeared “out of thin air.”
“Now Oprah is shocked by the aftermath of estrangement, after being one of the biggest voices pushing it for decades,” Canada-based Khazaal said in an Instagram video, which drew more than 27,000 likes and 3,000 comments.

Khazaal claimed that Winfrey’s messaging started in the 1990s and has contributed to a cultural shift where walking away became the first resort, not the last.
According to the relationship coach, millennials, some of whom grew up watching Oprah, are the leading demographic cutting off family members — and even if it wasn’t intentional, “the effect has absolutely been harmful,” Khazaal told Fox News Digital.
FAMILY BREAKUPS OVER POLITICS MAY HURT MORE THAN YOU THINK, EXPERT SAYS
The coach, who has her own history with estrangement, questioned why Winfrey is now treating the issue as a surprising crisis.
“Now she hosts a discussion with estranged parents and estranged kids, speaking on estrangement like it’s some hidden, sudden, heartbreaking epidemic that she had no hand in,” she said in her video.

Khazaal said she believes discussions about estrangement are necessary, but insists that people shouldn’t “rewrite history.”
“Estrangement isn’t entertainment or a trending conversation piece,” she added. “It’s real families, real grief, parents dying without hearing their child’s voice.”

Winfrey reportedly responded in the comments, writing, “Happy to have a conversation about it — but not on a reel. Will have my producer contact you if you’re interested.” But the comment was later deleted due to the backlash it received, Khazaal told Fox News Digital.
“I would still be open to that discussion,” Khazaal said. “The first thing I’d want her to understand is simple: Setting aside cases of abuse or danger, the family unit is the most sacred structure we have.”

“When children lose their sense of belonging at home, they search for it in the outside world,” she added. “That’s contributing to the emotional fragility we’re seeing today.”
Her critique ignited a debate online, with some social media users saying Khazaal is voicing a long-overdue concern.

“The first time I heard, ‘You can love them from a distance’ was from Oprah … in the ’90s,” one woman said.
“My son estranged himself from us for five years,” one mother commented. “The pain, hurt and damage never goes away.”

Others, however, argued that Winfrey’s podcast episode was empathetic and that estrangement shouldn’t be oversimplified.
Mental health experts say the conversation around estrangement is more complex than any single celebrity influence, and reflects broader cultural shifts.

In the episode with Winfrey, Joshua Coleman, a California-based psychologist, said, “The old days of ‘honor thy mother and thy father,’ ‘respect thy elders’ and ‘family is forever’ has given way to much more of an emphasis on personal happiness, personal growth, my identity, my political beliefs, my mental health.”
Coleman noted that therapists sometimes become “detachment brokers” by unintentionally green-lighting estrangement.

Jillian Amodio, a licensed master’s social worker at the Maryland-based Waypoint Wellness Center, told Fox News Digital that while public figures like Winfrey help normalize these conversations, estrangement might just be a more openly discussed topic now.
“Estrangement used to be handled privately and quietly,” she said.

Susan Foosness, a North Carolina-based clinical director of patient programs at Rula Health, said families can strengthen their relationships by working with a mental health professional to improve communication, learn healthier conflict-resolution skills, and build trust and empathy through quality time together.
“No family is perfect,” Foosness told Fox News Digital.
Khazaal agreed, saying, “Parents need to learn how to listen without slipping into justification, and children need help speaking about their pain without defaulting to blame or avoidance.”

Major measles outbreak leads to hundreds quarantined in US county, officials say
NEWYou can now listen to Fox News articles!
South Carolina is facing a major measles outbreak, resulting in the quarantine of hundreds of residents.
The South Carolina Department of Health (DPH) reported in a media briefing on Wednesday that the current number of measles cases has reached 111 as part of the current Spartanburg County outbreak.
DPH first reported a measles outbreak in the Upstate region on Oct. 2.

“This significant jump in cases is unfortunate,” a DPH spokesperson commented on the outbreak.
Public exposure was identified at Inman Intermediate School, with 43 of their students in quarantine.
“This significant jump in cases is unfortunate.”
Eight other intermediate and middle schools in the area are also reportedly undergoing quarantine. The DPH said multiple students have had to quarantine twice due to repeat exposure.
“Vaccination continues to be the best way to prevent the disruption that measles is causing to people’s education, to employment and other factors in people’s lives and our communities,” the spokesperson said.

Out of the 111 confirmed cases, 105 were unvaccinated. Receiving a vaccination within 72 hours has been shown to prevent measles infection, the DPH spokesperson noted.
Some cases are related to travel exposure, while others are from an unknown source, suggesting that measles is circulating in the community, the DPH noted.

Connecticut has also reported its first measles case in four years, according to the Connecticut Department of Public Health.
The department confirmed on Thursday that an unvaccinated child in Fairfield County, under the age of 10, was diagnosed with measles after recently traveling internationally.
“Vaccination continues to be the best way to prevent the disruption that measles is causing,” a DPH spokesperson said. (iStock)
The child began to show symptoms several days later, including a runny nose, cough, congestion, fever and a rash starting at the head and spreading to the rest of the body.
The Connecticut DPH noted that measles is “highly contagious” and can spread quickly through the air via coughing or sneezing. The CDC has estimated that nine out of 10 unvaccinated individuals who encounter an infected person will develop the measles virus.
