• 0:01
  Speaker 1: Good morning everybody, and welcome. It's May eighteenth, or over
• 0:04
  Speaker 1: halfway through the month of May. Already today a new
• 0:07
  Speaker 1: article comes out about your next stop at Starbucks or
• 0:13
  Speaker 1: any of the coffee shops, and you get a to
• 0:16
  Speaker 1: go cup to go, you put that little sleeve on
• 0:20
  Speaker 1: there so it doesn't burn your hand. Scientists now measured
• 0:23
  Speaker 1: microplastics in those coffee cups to go cups. We're gonna
• 0:27
  Speaker 1: see what it says again a reason to protect yourself.
• 0:30
  Speaker 1: Stay tuned, hi, and welcome to Health Talk with Doctor Lynn,
• 0:33
  Speaker 1: your daily dose. The information you hear on the show
• 0:36
  Speaker 1: is informational. It's not meant to diagnose or treat any disease.
• 0:41
  Speaker 1: Any kind of complete health conditions must be checked out
• 0:45
  Speaker 1: and discussed with your primary care physician. Get ready for
• 0:49
  Speaker 1: the good news of the day. God bless you, folks,
• 0:53
  Speaker 1: and here is doctor Lynn. Our daily devotional today comes
• 0:56
  Speaker 1: from the Book of John Chapter four. Come to me
• 1:00
  Speaker 1: with your plans held in ambiance. Worship me in spirit
• 1:05
  Speaker 1: and truth, allowing my glory to permeate your entire being.
• 1:08
  Speaker 1: Trust me enough to let me guide you through the day,
• 1:11
  Speaker 1: accomplishing my purchase purposes in my timing. Subordinate your myriad
• 1:17
  Speaker 1: plans to my master plan. I'm sovereign over every aspect
• 1:20
  Speaker 1: of your life. The challenge continually before you is to
• 1:24
  Speaker 1: trust me and search for my way through each day.
• 1:26
  Speaker 1: Do not blindly follow your habitual route, or you miss
• 1:29
  Speaker 1: what I have prepared for you. As the heavens are
• 1:32
  Speaker 1: higher than the earth, so are my ways higher than
• 1:34
  Speaker 1: your ways, and my thoughts higher than your thoughts. Good
• 1:39
  Speaker 1: thoughts to think about today. Stay tuned seven two seven,
• 2:57
  Speaker 1: nine one six four two one five. The same cup
• 3:00
  Speaker 1: that keeps your coffee warm may be the very thing
• 3:03
  Speaker 1: that makes it less less safe to drink. A recent
• 3:07
  Speaker 1: study found that heat can release thousands of hundreds of
• 3:10
  Speaker 1: thousands of microplastics into a beverage, depending on the cut
• 3:13
  Speaker 1: material and temperature, raising questions about one of the world's
• 3:16
  Speaker 1: most common daily habits. The study, published in the Journal
• 3:20
  Speaker 1: of Hazardous Materials Plastics, found that heat is a key
• 3:24
  Speaker 1: driver of microplastic release from disposable containers. While microplastics leached
• 3:29
  Speaker 1: regardless of the temperatures at which the beverage was held,
• 3:32
  Speaker 1: leeching levels increased with the temperature rising. Researchers first analyzed
• 3:37
  Speaker 1: data from thirty peer reviewed studies on microplastic release from
• 3:41
  Speaker 1: various plastic products focusing on factors such as temperature and
• 3:45
  Speaker 1: soaking time. Products made of polyethylene, polyethylene, turf thiolate, polypropylene,
• 3:52
  Speaker 1: polystyrene showed significant increases in microplastic release as temperatures rose,
• 3:58
  Speaker 1: with the most profound effects and the high temperature range
• 4:01
  Speaker 1: typically of hot beverages. Polyethylene is commonly used in plastic
• 4:06
  Speaker 1: cups and liners, polypropylene is a takeaway containers and lids,
• 4:13
  Speaker 1: Polystyrene is foam cups and food packaging, and propylene is
• 4:20
  Speaker 1: in beverage bottles. Among these, the pet that let me see.
• 4:27
  Speaker 1: Polyethylene ter thiolate is generally showed the smallest increases in
• 4:32
  Speaker 1: the release of the rising temperature, suggesting greater thermal stability
• 4:36
  Speaker 1: than the other types. So again PE plastic cups and liners, PP,
• 4:41
  Speaker 1: takeaway containers and lids, PS, foam cups and food packaging, PET,
• 4:47
  Speaker 1: beverage bottles. Across studies, higher temperatures, especially above one hundred
• 4:51
  Speaker 1: and forty, linked to a sharper rise in those very
• 4:54
  Speaker 1: small particles under one micrometer relative to larger particles, suggesting
• 4:59
  Speaker 1: that heat accelerates surface breakdown. Cups and food containers showed
• 5:04
  Speaker 1: much stronger temperature related increases in microplastic release than bottles,
• 5:08
  Speaker 1: which usually made from more heat resistant plastics and are
• 5:11
  Speaker 1: less often used with hot liquids. The extent of leaching
• 5:15
  Speaker 1: varied widely depending on the material study design, with some
• 5:19
  Speaker 1: individual studies finding single conditions yielding hundreds and even hundreds
• 5:23
  Speaker 1: and hundreds of thousands of particles per liter of water temperature. However,
• 5:27
  Speaker 1: the time of beverage was left in the container wasn't
• 5:30
  Speaker 1: a consistent driver of microplastic leaching for temperature wise. For
• 5:35
  Speaker 1: a real world measure, researchers collected hundreds of coffee cups
• 5:39
  Speaker 1: made of two major types pe plastic cups and paper
• 5:43
  Speaker 1: cups lined with polyethylene coating, which looked like paper but
• 5:46
  Speaker 1: have a thin inner plastic layer to make them waterproof.
• 5:50
  Speaker 1: Study had two parts. The first involved analyzing existing research,
• 5:53
  Speaker 1: while the second involved a real world experiment. While the
• 5:56
  Speaker 1: review included several common plastics, the experimental portion of the
• 6:00
  Speaker 1: study focused specifically at two plastic types, which were identified
• 6:04
  Speaker 1: among the most commonly used takeaway cup types. In the experience,
• 6:07
  Speaker 1: the cups were filled with purified water with minerals and
• 6:11
  Speaker 1: ions removed to avoid background contamination at forty one degrees
• 6:14
  Speaker 1: Fahrenheite and one hundred and forty degrees fahrnhite to simulate
• 6:18
  Speaker 1: iced at hot coffee temperatures, respectively, The water was left
• 6:22
  Speaker 1: to sit for thirty minutes, a duration choosen to reflect
• 6:25
  Speaker 1: typical beverage contact time rather than long term storage, while
• 6:29
  Speaker 1: it was covered to avoid air borne contamination. Microplastics leached
• 6:34
  Speaker 1: into the water were then collected by filtration and analyzed.
• 6:37
  Speaker 1: The authors noted that temperature alone may not fully reflect
• 6:40
  Speaker 1: real world beverages, since factors such as coffee acidity and
• 6:44
  Speaker 1: milk fact could further influence all plastic shed particles. Both
• 6:48
  Speaker 1: cup types leached microplastics at both temperatures, but pe plastic
• 6:52
  Speaker 1: cups released more than the pe coated paper cups. Raising
• 6:56
  Speaker 1: the water temperature from cold to hot increased microplastic reasse
• 7:00
  Speaker 1: by roughly one third. Using microscopes to examine the inner surfaces,
• 7:06
  Speaker 1: the researchers found that heat exposure increased the surface roughness
• 7:09
  Speaker 1: of the polyethylene cups, creating a more uneven, damaged surface
• 7:13
  Speaker 1: prone to shedding particles. Their chemical analysis showed little evidence
• 7:17
  Speaker 1: that the heat change the plastics chemical composition indicated the
• 7:20
  Speaker 1: increase was driven by physical surface degradation rather than chemical breakdown,
• 7:28
  Speaker 1: so they're saying it's more complicated than just a label.
• 7:32
  Speaker 1: Lisa's Zimmerman, the lead author of the review, was not
• 7:35
  Speaker 1: involved in the study at this time, said microplastic release
• 7:38
  Speaker 1: depends more on whether the part product is labeled PE
• 7:42
  Speaker 1: or PET. Even two plastics identified as polyethylene can differ substantially.
• 7:47
  Speaker 1: The individual product and its handling determines the microplastic release.
• 7:52
  Speaker 1: Jane Munchi, managing director and chief Scientific officer with the
• 7:55
  Speaker 1: Food Packaging Forum in Zurd, Switzerland, said that paperffee cups
• 8:00
  Speaker 1: are also typically stacked during transport and storage. If printed
• 8:03
  Speaker 1: on the outside, the cup's exterior can touch another cup's interior,
• 8:07
  Speaker 1: process known to set off migration, allowing printing inks to
• 8:10
  Speaker 1: transfer to the food contact surface and potentially migrate into
• 8:14
  Speaker 1: hot drinks. Globally, an estimated two hundred and fifty to
• 8:17
  Speaker 1: three hundred billion single use disposable cups are discarded each year.
• 8:22
  Speaker 1: Growing evidence suggests these everyday products may also be a
• 8:25
  Speaker 1: source of microplastic exposure. While some studies suggest micro's plastic
• 8:30
  Speaker 1: exposure may trigger inflammation, oxidative stress, an immune response. Researchers
• 8:35
  Speaker 1: caution that there is still no clear consensus and how
• 8:38
  Speaker 1: much accumulates in the body. How do you enjoy your
• 8:41
  Speaker 1: coffee with fewer contaminants? Avoid heating food or drinks and
• 8:45
  Speaker 1: plastic containers. Let very hot foods or drinks cool sludy
• 8:48
  Speaker 1: before transferring them to plastic cups. Offer reusable non plastic
• 8:52
  Speaker 1: material sets as glass, ceramic, or stainless steel. Minimize wear
• 8:56
  Speaker 1: on plastic items and scratched and degraded plastics shed more.
• 8:59
  Speaker 1: Part of avoid plastic in both cups and preparation tools.
• 9:04
  Speaker 1: Choose paper tea bags for switch to loose leaf tea,
• 9:07
  Speaker 1: as some tea bags contain plastic. Many people started to
• 9:12
  Speaker 1: avoid plastic containers because of BPA bisp in la, a
• 9:16
  Speaker 1: chemical that has raised concerned about potential hormone disrupting effects.
• 9:20
  Speaker 1: The single use plastics are unavoidable. One of the easiest
• 9:22
  Speaker 1: ways to identify plastic types is by checking the recycling
• 9:25
  Speaker 1: code number from one to seven is stamped on the product.
• 9:29
  Speaker 1: These numbers generally correspond to specific polymers such as polyethylene
• 9:32
  Speaker 1: and et cetera. Some experts point to composable cops as
• 9:37
  Speaker 1: an alternative. Hoever, Zimmerman notes it even disposable cups made
• 9:40
  Speaker 1: from composable plastics are still plastics, therefore just as prone
• 9:44
  Speaker 1: to releasing microplastics. Remove Complete should be a part of
• 9:53
  Speaker 1: your normal regimen. Just take it away from all your
• 9:56
  Speaker 1: other supplements or any medications. Bedtime can do an amazing
• 10:01
  Speaker 1: job of keeping the body where it needs to. You
• 10:03
  Speaker 1: can find all that information on nutritional frontiers dot com.
• 10:06
  Speaker 1: The prep again called remove Complete. God bless you folks,
• 10:11
  Speaker 1: enjoy your
