Reviews

4.4 out of 5 stars from 1.2k ratings
  • Good content, bad sound quality

    Love the content and insightful discussions, but I beg of you to work on the sound quality of the show. It’s bad enough that I am deducting stars from the rating of the show based on sound quality alone. There are several reviews that have commented on this over the years, yet there has been no care to fix this issue.

  • Good content, weird sound effects and affectations

    Another update: You’re losing me with the plastic episode. I just don’t find the guest credible. It is good that you announced the sponsorship but it still makes me suspicious of the credibility of the information for the first time.

    Update: Took away a star because while the content is still good and the guests are fantastic, the sound effects are still SO CRINGE! Please get rid of them. They are startling and confusing and juvenile; they sound like a phone alarm or an alert on the car or ano... more

  • Science Without the Politics

    I really appreciate that the hosts (and guests) use scientific grounding as the basis of their arguments. In a day and age where politics are so divisive, it’s refreshing to have a podcast that dishes me the facts and expert opinions, and then gives me the tools and information so that I can make my own evidence-based conclusions about each topic they discuss. So grateful for the hosts who sift through the clickbait and present scientific facts.

Talking Points

Recent interactions between the hosts and their guests.

Don't Sleep on Melatonin Science
Q: Are there any disqualifying characteristics or interactions that would make melatonin unsuitable for some children?
There are some Med interactions to consider and certain medical histories (e.g., severe headaches, overdose risk with gummies); consult a pediatrician or primary care provider to determine suitability for a given child.
Dissolving the Myths on Dishwasher and Laundry Pods (See What We Did There?)
Q: Can you start with a definition of microplastics and explain why there isn't a single definition?
There isn't a single definition because different stakeholders weigh factors like whether the material is human-made or natural and whether to emphasize size or source; however, the body does not distinguish between human-made or natural when it comes to chemistry and biology, so the focus should be on how the material interacts with the body and the environment rather than chasing a strict label.
When The Diagnosis Is Thrown For A Lupus
Q: What signs point toward the newer treatment modalities, like cell therapy, and how do they work?
Recent advances show that immune system resetting therapies can reduce disease activity and allow long remission; these approaches aim to eliminate autoimmune cells and reconstitute the immune system, potentially providing durable control or remission of lupus.
When The Diagnosis Is Thrown For A Lupus
Q: What makes lupus so challenging to diagnose given its multi-organ involvement?
Lupus often presents with non-specific symptoms and only a minority of patients show classic manifestations; clinicians rely on a differential diagnosis, targeted blood work for autoantibodies, and clinical history to narrow down possibilities before confirming lupus.
Where There's Vape, There's Fire: E-Cig Hype, Harm, and Hope??
Q: Why is there substantial pushback from the public health community on e-cigarettes?
Some public health groups initially tied e-cigarettes to big tobacco and were wary of promoting a product perceived as a potential gateway or industry-friendly tool; over time, data has shown relative safety compared to combustible cigarettes, but regulatory and marketing concerns persist, especially around youth uptake.
