Wake Me Up When Thanksgiving Ends
On this week's episode of the pod, we tackle a topic inspired by Thanksgiving-- tryptophan! (You know, the amino acid found in turkey that people claim makes us hit the couch after we polish off our Thanksgiving plate!)Well, we dish (pun intended) on its biochemistry and its relationship to serotonin and melatonin. Next, we dive into the claims about whether it makes us sleepy, how much of it is found in turkey, and discuss the (many!) other sources of tryptophan in foods other than turkey. We spend some time talking about L-tryptophan supplements and whether there is evidence that they can help with sleep issues, as well as anxiety and/or depression. We wrap things up with a discussion on the potential harms of L-tryptophan supplements, including drug interactions and a rare muscle disorder. You may pick up some interesting nuggets and factoids that you can bring to the Thanksgiving table! This is our last episode before Thanksgiving, but will be back in a couple of weeks.

Flu Shook Me All Night Long
On this episode of the pod, we cover a very timely and important topic-- influenza (aka the flu) and the flu vaccine.Yes – we know we tackled this a couple of years ago, but with some concerning data from the Southern Hemisphere and early data from the Northern Hemisphere on the 2022 flu season, we figured it was worth revisiting. We present the latest population health statistics and trends, as well as predictions for this flu season. We give a refresher on influenza viruses and why they mutate faster than other viruses. We discuss flu shots and who should get them, and why it's important to get an annual flu shot (especially this year!) even if you're healthy and have never had the flu before. We of course address some common flu vaccine myths and misconceptions. You can find a flu vaccine by visiting vaccines.gov and entering your zip code. Tune in to learn more about the flu and flu vaccines (and schedule your shot today)!A note on this episode: Unbiased Science is a non-profit organization dedicated to improving the well-being of individuals, families, and communities by producing and delivering educational content that builds health and scientific literacy.

Weed Love to Know the Data on THC
On this week's episode of the pod, we talk THC (the high-producing cousin of CBD that we tackled last week). We kick things off with a molecular biology primer on THC, endocannabinoids, and why marijuana elicits a high. We discuss THC's effects on the brain and how it impacts movement, learning, and cognitive function. We take a brief detour to tackle the legality of marijuana and some reasons why people advocate for and against its decriminalization. We chat about Delta 8 THC (and how it is different from Delta 9) and its growing popularity. Next, we spend some time covering different ways that THC can be consumed and the respective ways body and mind are impacted. We of course tackle the available evidence on THC's effectiveness against several outcomes such as chronic pain, anxiety, and neurological issues, as well as potential harms. We wrap things up with a brief conversation about whether marijuana is a gateway drug. Yep, we hit all the high points-- pun intended.

CBD: Your Best Bud, Or Just A Dud?
On this week’s episode of the podcast, we tackle something that is growing rapidly in popularity—CBD—but does it live up to its hype?We set the stage by discussing the different forms of CBD and the ways we can ingest it. We dive into the claims made by CBD companies, including that it can help with skin conditions, mental health, and even chronic diseases. Then we do a little microbiology refresher on the chemical makeup of CBD, and differentiate it from its cousin, THC. We talk a bit about hemp-derived CBD versus marijuana-derived CBD, and some of the legal issues surrounding the production and sale of CBD products. We discuss the effects of CBD on our body and consciousness and the reasons why some people use CBD. Next, we do a deep dive on the available research on CBD’s effectiveness for a variety of outcomes, as well as the limitations of the current evidence. We even talk about CBD’s use among dogs and cats! We discuss FDA regulation of CBD (rather, lack thereof) and how there is only one FDA-approved CBD-based drug on the market.

Monkeypox and Polio: Mo' Viruses, Mo' Problems
On this week’s episode of the pod– we’re going viral (but not in the good way).We tackle two viruses that have been on our radar: monkeypox virus and poliovirus. We start our discussion focused on monkeypox– what it is, how it’s caused, how it’s spread, and clinical signs and symptoms. We provide a status update on the monkeypox update which (we hope) most will find comforting and optimistic. (TL;DR: We aren’t fully out of the weeds, but things appear to be slowing thanks to vaccines and behavioral change.) Next, we talk about polio. We didn’t see this coming, either, but here we are! We discuss why we’re seeing a resurgence of polio (spoiler alert: it has to do with low vaccination rates in pockets of the population). We discuss signs and symptoms, asymptomatic versus symptomatic infection, viral transmission modalities, and different outcomes associated with illness. We take a trip down polio vaccine memory lane (whattup, Jonas Salk!) and the importance of getting vaccinated as recommended.

COVID-19: Frankly, My Dears, We Still Need to Give A Damn!
On this episode of the podcast, we tackle a topic that many of us wish we could put behind us once and for all: COVID-19.We kick things off with some updated data on the state of COVID-19 hospitalizations and the significant undercounting of cases—and that, despite our wishes, we still need to have COVID-19 on our radar. We spend some time discussing the new bivalent COVID-19 booster and some newly available data on its efficacy. We then chat about low vaccine and booster uptake and some potential reasons why we aren’t seeing better vaccine uptake, particularly among young children. We discuss long COVID—some new information on whether vaccines can impact the likelihood of long COVID, as well as the need for more research in this area. Finally, we spend some time discussing President Biden’s recent comment about the pandemic being over. Spoiler alert: we don’t think it’s quite as cut and dry as that, and feel we are in a subacute pandemic state.

Oops, Naturopathy Did It Again—It’s Not That Innocent! (Part 2)
On this week's episode of the pod, we continue our conversation about the practice of naturopathy.We kick things off with a deep dive on the training received by NDs and how it compares to the training received by MDs and DOs. We discuss the US Department of Health and Human Services' stance on naturopathy and present statements from some of the major national medical and scientific associations. We continue on to discuss the anti-vaccine sentiment and rhetoric within the naturopathic community, naturopathic "treatments" for COVID-19, cancer, and more. We discuss the potential harms of naturopathy and the unproven and even disproven "treatments" that are often implemented-- some of which have cost people their lives.

Oops, Naturopathy Did It Again—It’s Not That Innocent!
Welcome back to season 3 of the pod!We kick things off this season with the topic of naturopathy. This is the first episode in a two-part series on this controversial topic. We set the stage by explaining why many people seek out alternatives to conventional medicine; including ongoing pain and chronic illness, frustration with long wait times for appointments, feeling like they're not "heard" by physicians, lack of emphasis on nutrition and mental health counseling, and more-- which are valid concerns with our healthcare system. However, we explain that naturopathy is NOT an innocuous alternative to conventional medicine. It is an industry that is not based on science or evidence and can actually be quite harmful. We discuss the training (or lack thereof) that naturopaths receive and statements from national medical organizations cautioning against naturopathy. We bring on a very special guest, Britt Hermes, a former naturopath, to help provide insider knowledge on this industry.

Menstrual Myths Really Cramp Our Style! The Truth About Periods, Tampons, and Pads: Part 2
Sponsored by Tampax and Always. On this episode of the podcast, we are BACK to tackle more period and period product myths! We kick things off with a continuation of our discussion of organic cotton versus conventional cotton period products (and how there is no difference in safety profile of the cotton). We talk about how both organic and conventional cotton tampons are made and the elemental chlorine-free purification process, and why that means tampon manufacturing today would never produce dioxins as a result. We discuss the high-quality standards that are adhered to during manufacturing to ensure tampons are safe for use. Next, we talk about period blood and how it is not dirty or unhygienic! That being said, it's not a good idea to rub menstrual blood on your face. We wrap things up with a discussion of the pros and cons of different available period products. Remember, all options are great-- you just need to choose the product that works best for you and your body. This is our last episode of season 2, and you don't want to miss it!

Menstrual Myths Really Cramp Our Style! The Truth About Periods, Tampons, and Pads
Sponsored by Tampax and Always. On this episode of the pod, we answer a bunch of questions that we have received about periods and period products, and debunk myths about tampons and pads. We kick things off with a discussion of the menstrual cycle and variations in cycle length and flow across individuals. We take a trip down memory lane to discuss the history of period products and how they came to be. We spend some time talking about the safety and regulation of period products (and how products have improved over time). We talk about the stigma surrounding tampon use, in particular, and the importance of openly discussing periods and period products. We spend a good amount of time talking about mTSS (menstrual toxic shock syndrome)--—what it is, rates of mTSS in population, and risk of mTSS. And finally, we spend some time addressing chemophobia surrounding these products and set the stage for part-two of this episode series that will compare organic versus conventional tampons (and much more).
