  Good morning, everyone, and welcome to another episode of Morning Medical with Dr.
• 0:04
  Chow.
• 0:05
  I'm your host, Dr.
• 0:06
  Chi-Ming Chow.
• 0:08
  Today, we're going to dive into some fascinating new research that could have
• 0:12
  implications for how we think about our daily cup of tea.
• 0:16
  A recent study from Northwestern University in Illinois has found that brewing tea can
• 0:21
  actually remove harmful toxins from water.
• 0:24
  Let's explore what this means for us.
• 0:29
  Tea is widely recognized as one of the healthiest beverages, and it turns out that the
• 0:34
  benefits might extend beyond just what's in the cup.
• 0:37
  According to the study, the process of brewing tea can remove toxic heavy metals like lead and
• 0:44
  cadmium from drinking water.
• 0:47
  This is achieved because the tea leaves absorb these metals during brewing, preventing them
• 0:51
  from entering the water we consume.
• 0:54
  The researchers tested a variety of tea types, tea bags, and brewing methods to see how
• 1:00
  effectively they could absorb heavy metals such as lead, chromium, copper, zinc, and cadmium.
• 1:07
  Interestingly, they found that even a typical cup of tea, brewed for about three to five
• 1:12
  minutes, could remove roughly 15% of lead from the water.
• 1:16
  One of the key findings was that the longer the tea is brewed, the more metal content is
• 1:21
  reduced.
• 1:22
  So, if you're someone who enjoys letting your tea steep for a longer period, you might be
• 1:28
  getting even more benefits from this detoxifying effect.
• 1:32
  The study even noted that brewing tea for extended periods, like overnight in the case of
• 1:38
  iced tea, could potentially recover most or nearly all of the metals from the water.
• 1:44
  Despite these promising findings, the researchers caution that tea should not be
• 1:48
  relied upon as a primary method to purify water.
• 1:52
  They emphasize that the levels of lead reduction observed in their study might not
• 1:56
  necessarily translate to significant health benefits on a population-wide scale.
• 2:01
  However, it is still useful to know that brewing tea could marginally reduce one's
• 2:06
  exposure to lead and possibly other toxins from drinking water.
• 2:11
  This study might also shed light on why populations that consume more tea tend to have
• 2:16
  lower incidences of heart disease and stroke.
• 2:19
  While it's too soon to make definitive claims, the researchers suggest that across a
• 2:23
  population, drinking an extra cup of tea per day could potentially lead to declines in
• 2:28
  illnesses associated with heavy metal exposure over time.
• 2:33
  John Rumpler, the lead author of the study, also highlighted the widespread issue of lead
• 2:39
  contamination in drinking water, particularly in schools and child care centers.
• 2:45
  While brewing tea might offer some help, he points out the importance of using filters
• 2:50
  certified to remove lead and replacing old water fountains with lead-filtering stations
• 2:56
  wherever possible.
• 2:59
  Today, we're addressing some recent comments made by Robert F.
• 3:02
  Kennedy Jr., who during a cabinet meeting of the new Trump administration, stated that
• 3:07
  measles outbreaks are "not unusual" in the United States.
• 3:11
  This statement has sparked quite a reaction in the medical community, as many experts have
• 3:16
  come forward to refute this claim.
• 3:19
  Dr.
• 3:21
  Christina Johns, a pediatric emergency physician, emphasized that classifying measles
• 3:26
  outbreaks as "not unusual" is inaccurate.
• 3:29
  She pointed out that outbreaks typically involve only a handful of cases, unlike the
• 3:33
  recent outbreak in West Texas, which involved over one hundred people.
• 3:37
  This is far from the norm.
• 3:39
  Dr.
• 3:40
  Philip Huang, the director of the Dallas County Health and Human Services Department, also
• 3:45
  disagreed with Kennedy's statement.
• 3:48
  He noted that such outbreaks are not common, largely due to the effectiveness of vaccines.
• 3:55
  This effectiveness has historically kept the United States free from large-scale outbreaks.
• 4:01
  Dr.
• 4:01
  Lara Johnson, the chief medical officer of Covenant Health Lubbock Service Area, remarked
• 4:08
  that the United States had reached a point where these types of outbreaks were a rarity.
• 4:14
  However, she acknowledged that the situation has changed over the past two decades, largely
• 4:19
  due to varying vaccination rates.
• 4:22
  Interestingly, the current outbreak in West Texas, which accounts for about ninety percent
• 4:28
  of all measles cases in the United States this year, is the largest in the state in thirty
• 4:33
  years.
• 4:34
  This outbreak started in a largely unvaccinated rural Mennonite community, where misinformation
• 4:40
  about vaccines had taken hold.
• 4:44
  Dr.
• 4:44
  Peter Hotez, co-director of the Texas Children's Hospital Center for Vaccine
• 4:48
  Development, expressed concern that anti-vaccine activist groups have influenced
• 4:52
  these communities, leading to lower vaccination rates.
• 4:56
  In Gaines County, at the center of the outbreak, nearly one in five kindergartners did
• 5:02
  not receive the measles-mumps-rubella vaccine during the last school year.
• 5:07
  According to the United States Centers for Disease Control and Prevention, measles was
• 5:11
  eliminated in the country in 2000, meaning outbreaks did not persist for a year or more.
• 5:17
  However, since then, cases have reemerged, often linked to international travel.
• 5:22
  The current situation, however, is far from typical, as most recent cases were isolated
• 5:28
  until this large outbreak in Texas.
• 5:31
  Declining vaccination rates are a significant concern, as they have contributed to the recent
• 5:37
  increase in measles cases.
• 5:40
  The country has not met the ninety-five percent vaccination threshold necessary to prevent
• 5:45
  outbreaks for four consecutive years.
• 5:48
  This threshold is crucial because measles is highly contagious, and without adequate
• 5:52
  vaccination, outbreaks can occur rapidly.
• 5:57
  Dr.
• 5:58
  Christina Johns lamented the fact that any death from a vaccine-preventable illness is one
• 6:03
  too many.
• 6:04
  She stressed the importance of taking these outbreaks seriously and ensuring that
• 6:08
  misinformation does not undermine public health efforts.
• 6:12
  Ultimately, the message from health experts is clear: Vaccination remains the best defense
• 6:18
  against measles.
• 6:19
  The measles-mumps-rubella vaccine is ninety-seven percent effective with two doses.
• 6:24
  By maintaining high vaccination rates, we can prevent future outbreaks and protect public
• 6:29
  health.
• 6:30
  Dr.
• 6:31
  Chi-Ming Chow: Let's turn our attention to some intriguing new research highlighting the role
• 6:37
  of exercise in reducing the risk of brain diseases like anxiety, depression, and
• 6:42
  dementia.
• 6:43
  This study, led by Dr.
• 6:45
  Jia-Yi Wu from Huashan Hospital at Fudan University in Shanghai, China, underscores the
• 6:50
  importance of regular physical activity for mental health.
• 6:53
  Dr.
• 6:54
  Chi-Ming Chow: The researchers analyzed data from over seventy-three thousand adults, using
• 7:01
  accelerometers to measure physical activity levels and correlate them with instances of
• 7:05
  neuropsychiatric diseases.
• 7:08
  Although this research is still in its preliminary stages, it's set to be presented at
• 7:13
  the American Academy of Neurology's annual meeting in April.
• 7:16
  Dr.
• 7:17
  Chi-Ming Chow: Dr.
• 7:20
  Scott Russo, who was not involved in the study, noted that the findings are backed by a large
• 7:25
  sample size and reliable data.
• 7:27
  He points out that there's already a substantial body of evidence supporting the
• 7:31
  link between exercise and improved brain health outcomes, giving him confidence in these new
• 7:36
  results.
• 7:37
  Dr.
• 7:38
  Chi-Ming Chow: Interestingly, the study found that any increase in physical activity,
• 7:44
  regardless of intensity, can be beneficial.
• 7:47
  This is particularly good news for those who may not enjoy high-intensity workouts.
• 7:52
  Simple activities like walking or gardening can play a significant role in protecting brain
• 7:56
  health.
• 7:57
  Dr.
• 7:58
  Chi-Ming Chow: It's worth noting that exercise might be as effective as medication for
• 8:05
  conditions like depression.
• 8:07
  Some researchers are beginning to view depression as a collection of subtypes with
• 8:11
  different causes, such as inflammation or metabolic dysfunction.
• 8:16
  Exercise could potentially regulate these factors, providing an effective treatment for
• 8:20
  certain subtypes of depression.
• 8:21
  Dr.
• 8:23
  Chi-Ming Chow: The key takeaway here is to encourage more movement and less sedentary
• 8:28
  time.
• 8:29
  Engaging in daily activities that burn calories, no matter how light, can have a
• 8:34
  meaningful impact on your well-being.
• 8:37
  Dr.
• 8:38
  Wu emphasized that even light-to-moderate activities are beneficial.
• 8:41
  Dr.
• 8:42
  Chi-Ming Chow: Using devices like accelerometers to track activity can also help
• 8:48
  motivate individuals to move more.
• 8:51
  While doctors have long recommended increased physical activity, our overall health has not
• 8:56
  improved significantly.
• 8:59
  Dr.
• 9:00
  Russo suggests that digital technologies could play a crucial role in helping people take
• 9:05
  ownership of their health by tracking their progress in real-time.
• 9:09
  Dr.
• 9:10
  Chi-Ming Chow: For those looking for a guideline, adults should aim for at least one
• 9:16
  hundred and fifty minutes of moderate physical activity per week, along with two days of
• 9:21
  muscle-strengthening activities.
• 9:24
  Dr.
• 9:25
  Russo likened his own use of a fitness tracker to a game, setting daily movement targets to
• 9:30
  stay on track.
• 9:31
  Dr.
• 9:32
  Chi-Ming Chow: Ultimately, improving our population's health will require strategic and
• 9:39
  intentional choices.
• 9:41
  Digital tools can empower individuals by organizing and tracking their activity data,
• 9:47
  encouraging more active lifestyles and ultimately contributing to better brain health.
• 9:54
  In our final segment today, we turn our focus to a significant international development in
• 9:59
  the ongoing fight against the opioid crisis.
• 10:03
  Canada's newly appointed fentanyl czar, Kevin Brosseau, has reported a very positive
• 10:08
  reception from American officials during his recent meetings in Washington, D.C.
• 10:13
  This comes as part of Canada's broader efforts to tackle the flow of illicit drugs and
• 10:18
  migrants across the border.
• 10:20
  As the fentanyl czar, Brosseau serves as a primary contact for U.S.
• 10:26
  officials concerned about the trafficking of fentanyl across the Canada-U.S.
• 10:30
  border.
• 10:31
  In an interview with CBC's The House, he shared that his presence in Washington has resonated
• 10:36
  well with American counterparts, who have been supportive of his role and Canada's efforts.
• 10:42
  Brosseau is accompanied by key figures such as Public Safety Minister David McGuinty, Canada
• 10:48
  Border Services Agency president Erin O'Gorman, and Royal Canadian Mounted Police Commissioner
• 10:54
  Michael Duheme.
• 10:56
  Together, they're showcasing Canada's progress in curbing fentanyl trafficking, which is a
• 11:01
  critical issue given the recent decision by President Donald Trump to impose a twenty-five
• 11:06
  percent tariff on most Canadian goods, citing drug flow concerns.
• 11:12
  Despite President Trump's claims, data from the U.S.
• 11:16
  Customs and Border Protection shows a significant ninety-seven percent drop in
• 11:20
  fentanyl seizures in January compared to December 2024.
• 11:26
  This drop is being used by Canadian officials to highlight the effectiveness of their border
• 11:30
  security measures and to counter the rationale behind the tariffs.
• 11:36
  Canada has historically accounted for less than one percent of all seized fentanyl entering the
• 11:41
  United States, but the Canadian government is committed to addressing any concerns related to
• 11:46
  border security and drug trafficking.
• 11:49
  Public Safety Minister McGuinty emphasized that Canada has been meeting the standards set by
• 11:54
  the U.S.
• 11:55
  for border security, even as the tariff threats loom.
• 11:59
  Brosseau is keen on receiving feedback from U.S.
• 12:03
  officials about Canada's strategies.
• 12:05
  He expressed a desire to learn from their experiences and gather insights on what could
• 12:09
  be improved.
• 12:11
  Brosseau's proactive approach has been well-received, with Minnesota Senator Amy
• 12:15
  Klobuchar expressing her admiration for the measures Canada has implemented to tackle the
• 12:21
  fentanyl issue.
• 12:23
  Senator Klobuchar noted that while she cannot predict all of President Trump's actions,
• 12:28
  Canada's efforts meet her expectations.
• 12:31
  She stressed the importance of bilateral cooperation in addressing the fentanyl
• 12:35
  epidemic, underscoring that collective efforts are essential to combat this crisis
• 12:39
  effectively.
• 12:41
  Brosseau has articulated a clear vision for his role, which includes reducing fentanyl-related
• 12:46
  deaths and the overall demand for this dangerous drug in both countries.
• 12:52
  He believes in a multifaceted approach, combining law enforcement actions with
• 12:56
  collaborative efforts to achieve success in this challenging battle.
• 13:01
  As we wrap up today's episode, it's evident that the fight against fentanyl requires
• 13:06
  international cooperation and innovative strategies.
• 13:09
  Canada's engagement with U.S.
• 13:11
  officials marks a promising step in this direction.
• 13:14
  Let's hope these efforts continue to yield positive results for both countries.
• 13:19
