    Dr. Kari Nadeau: Microplastics in Our Bodies

    In this episode, Therese Markow and Dr. Kari Nadeau discuss the presence and health effects of microplastics in our bodies. Microplastics can enter our bodies through various environmental routes, including food, water, and air. They are in everyone's bodies to some degree.  Microplastics have been linked to health issues like stroke, cancer, and heart attacks. Simple actions like avoiding single-use plastics and processed foods can reduce microplastic levels in the blood by up to 80% in three months. Dr. Nadeau emphasizes the need for further research and consumer awareness to mitigate plastic pollution.   Key Takeaways: A microplastic, scientifically, is anything between 1 micron (the size of a red blood cell or an immune cell) to 5 millimeters (the size of a sesame seed). Anything smaller than that is a nanoplastic. Plastics are chemicals. Plastics, as we know them, did not exist before the 1940s. Now we see them in so many places, from healthcare to food to our clothing.  In the US, we are getting about a credit card's worth of plastic per week in what we eat. In Indonesia, it is more like a credit card amount per day. The amount varies around the world.    "We really need to think about air and water and soil as ways that these plastics can get into our bodies." —  Dr. Kari Nadeau   Episode References:  Environmental Working Group: https://www.ewg.org/  Jung YS, et al.

    Dr. Lise Eliot: Brain Development, Sex, Gender

    In this episode, Therese Markow and Dr. Lise Eliot discuss neurosexism and brain differences between males and females. Dr. Eliot explains that historical brain comparisons often aimed to prove women's inferiority, citing examples like weighing cadaver brains. Modern MRI studies show minor structural differences, but still present significant methodological challenges. She highlights that brain plasticity and social experiences shape gender differences, noting that women tend to have more active default mode networks, linked to anxiety and rumination. She emphasizes that gender is a psychological phenomenon, not strictly binary, and that early life experiences significantly influence brain development.    Key Takeaways: Sex is a biological phenomenon determined by physical characteristics and some secondary characteristics. Gender is a psychological phenomenon and is not binary - there are multiple dimensions of gender.  Without brain plasticity, you would be unable to learn anything. While the brain has more plasticity when you're young, the brain can continue to learn and form new pathways even in adulthood.  Gender is a uniquely human attribute - other animals do not have gender. This is something that humans have invented and reinvented in every culture to adapt our different physical bodies and reproductive roles to a social environment.   "I'm really starting to think about gender learning as almost like learning a language. You learn the language, you learn the rules and the symbols of being a boy or being a girl until it's finally internalized, and you reach this moment of gender identity thanks to endless clues in your environment, and this strong drive to find your place and find your identity and social community." —  Dr. Lise Eliot   Connect with Dr. Lise Eliot: Professional Bio: https://www.rosalindfranklin.edu/academics/faculty/lise-eliot/  LinkedIn: https://www.linkedin.com/in/lise-eliot-b0018713  Books: Pink Brain, Blue Brain: How Small Differences Grow into Troublesome Gaps and What We Can Do About It What's Going On in There?: How the Brain and Mind Develop in the First Five Years of Life   Connect with Therese: Website:  www.criticallyspeaking.net Bluesky: @CriticallySpeaking.bsky.social Instagram: @criticallyspeakingpodcast Email: theresemarkow@criticallyspeaking.net     Audio production by Turnkey Podcast Productions.

    Dr. Catherine Lebel & Dr. Sam Nivins: Disruptors of Fetal Brain Development

    In this episode, Therese Markow, Dr. Catherine Lebel, and Dr. Sam Nivins discuss the impact of prenatal factors on fetal brain development. Catherine explains how MRI can detect subtle brain changes due to prenatal alcohol exposure, even at low levels, and emphasizes the importance of avoiding alcohol during pregnancy. Sam discusses the effects of maternal obesity before pregnancy on brain development, noting sex-specific differences and the importance of early intervention. Both also touch on the impact of stressors, such as natural disasters, and the need for early identification and support for children with potential reading difficulties.     Key Takeaways: Even exposing a fetus to one alcoholic drink per week during pregnancy shows a detectable difference in brain structure compared to kids who had no alcohol exposure at all.  The same is true of prenatal maternal obesity, even if the obesity is preconceptional. Reading is a skill that must be taught to children. Prereading skills lay the foundation for later reading. And prereading skills can be visualized with brain imaging. When you know what part of the brain is affected, you can better tailor interventions to target those particular consequences.   "People who have good support from a partner or other folks in their lives, not only do they tend to do better, but their kids tend to do better too." —  Dr. Catherine Lebel   Connect with Dr. Lebel and Dr. Nivins  Dr. Lebel's Professional Bio & Publications: https://profiles.ucalgary.ca/catherine-lebel  Dr. Nivins' Professional Bio & Publications: https://ki.se/en/people/samson-nivins  Website: https://www.developmentalneuroimaginglab.ca/    Connect with Therese: Website:  www.criticallyspeaking.net Bluesky: @CriticallySpeaking.bsky.social Instagram: @criticallyspeakingpodcast Email: theresemarkow@criticallyspeaking.net   Audio production by Turnkey Podcast Productions.

    Dorothy Roberts: The Mixed Marriage Project - Race

    In this episode, Therese Markow and Dorothy Roberts discuss her book "The Mixed Marriage Project," which explores her father's unpublished research on mixed marriages in Chicago. Dorothy's father, a white anthropology professor, interviewed over 500 black-white couples from the 1930s to the 1960s. The book blends personal stories, historical insights, and interviews, revealing the challenges and discrimination faced by interracial couples. They also discuss Dorothy's mother's remarkable journey from Jamaica to Chicago and the impact of her parents' interracial marriage on her life. The book highlights systemic racism and the one-drop rule, emphasizing the need for societal love and equality.    Key Takeaways: All black movements can be linked back to the Marcus Garvey Movement, which started in Jamaica. Even within early mixed marriages and organizations for these couples, such as the Manassas Club, there were harmful stereotypes within these groups. To interracial couples, the biggest barrier was the barrier of the black belt that was created by racially restricted covenants and mob violence against black people.    "The One-Drop Rule was instituted to support white supremacy, and also it proves that race is not a natural division of human beings. Who is black, who is white, depends entirely on social rules, which might be instituted in law, or they're just part of societal norms and expectations. But they're not biological, they're not natural. They're made up." —  Dorothy Roberts   Connect with Dorothy Roberts: Professional Bio: https://www.law.upenn.edu/faculty/roberts1  Website: https://www.dorothyeroberts.com/   Book: https://www.simonandschuster.com/books/The-Mixed-Marriage-Project/Dorothy-Roberts/9781668068380    Connect with Therese: Website:  www.criticallyspeaking.net Bluesky: @CriticallySpeaking.bsky.social Instagram: @criticallyspeakingpodcast Email: theresemarkow@criticallyspeaking.net   Audio production by Turnkey Podcast Productions.

    Dr. Tami Rowen: Q and A - Women's Health

    In this episode, Therese Markow and Dr. Tami Rowen discuss the listener questions that arose from her last episode on Critically Speaking. From drinking soy milk as a substitute for estrogen, the complex relationship between the number of children you have and breast cancer risk, dense breast tissue, early menstruation, hormone replacement therapy, and more. Listen in for the answers to your questions!    Key Takeaways: Soy is not in any way a substitute for estrogen. How it affects your circulating estrogens depends on your age. While the number of kids you have is inconclusive regarding its relationship to breast cancer, breastfeeding has been shown in every study to be preventative against breast cancer. The number one killer of women is heart disease. It's not breast cancer.   "A period is a bleed in response to ovulation, and that is coming from the level of the hypothalamus, pituitary, ovary, and uterus, so you can have a problem at any of those levels." —  Dr. Tami Rowen   Episode Reference: Welcome to the Wild West of Testosterone: https://podcasts.apple.com/us/podcast/welcome-to-the-wild-west-of-testosterone/id1708072320?i=1000743735353    Connect with Dr. Tami Rowen: Professional Bio: https://profiles.ucsf.edu/tami.rowen  Website: https://www.ucsfhealth.org/providers/tami-rowen  Instagram: https://www.instagram.com/drtamirowen/    Connect with Therese: Website:  www.criticallyspeaking.net Bluesky: @CriticallySpeaking.bsky.social Instagram: @criticallyspeakingpodcast Email: theresemarkow@criticallyspeaking.net   Audio production by Turnkey Podcast Productions.

    Dr. Haley Hersant: Brain Health Supplements - Do They Work?

    In this episode, Therese Markow and Dr. Haley Hersant discuss a study by Dr. Hersant and her colleagues that reviewed over 100 brain and memory supplements. They found 18 common ingredients grouped into three categories: those with scientific evidence of benefit, those with no compelling evidence, and those with mixed results. They discuss the results of this study and emphasize the need for more rigorous testing. While not giving medical advice, they caution against potential interactions with prescription medications and advise listeners to do their research as well as talk to their own providers.   Key Takeaways: The most common factor across all of these ingredients that had some benefit is that, theoretically, they are known to decrease inflammation and help activate cellular repair pathways. The FDA does not have the authority to approve dietary supplements before they are put on the market, so it primarily regulates them once they are already on the market. This is different from traditional pharmaceuticals. If you are taking supplements, do report them when completing a medical history with your doctor, as they can interact with your prescriptions, vitamins, and other supplements.   "For many people, it could be harmless to be taking these supplements. They may be wasting their money without getting much benefit. But health-wise, they may be okay. However, whenever you start mixing a lot of different supplements, or are taking supplements with prescription medications, there are certainly some risks that can come into play." —  Dr. Haley Hersant   Episode References:  Over the Counter Supplements for Memory: A Review of Available Evidence   Connect with Dr. Haley Hersant: LinkedIn: https://www.linkedin.com/in/haley-hersant-79a0b12a4/    Connect with Therese: Website:  www.criticallyspeaking.net Bluesky: @CriticallySpeaking.bsky.social Instagram: @criticallyspeakingpodcast Email: theresemarkow@criticallyspeaking.net   Audio production by Turnkey Podcast Productions.

    Adam Morgan: A Danger to the Minds of Young Girls

    In this episode, Therese Markow and Adam Morgan discuss Adam's new book, A Danger to the Minds of Young Girls, which explores the life and legacy of Margaret C. Anderson. Margaret was a pioneering figure in modern literature, the founder of "The Little Review" in Chicago, and one of the key figures in fostering the Chicago literary renaissance. They talk about the challenges she faced, despite her initial successes, why her physical appearance often overshadowed her contributions, and the impact on young girls today that Margaret also faced during her time.     Key Takeaways: "The Little Review" served as a platform for uncensored conversations about literature and art, including experimental works that were often undiscovered during her time. The Comstock Act was a group of federal laws that banned the mailing of "obscene materials" and was upheld, in part, through censorship at what is now the USPS. This resulted in many copies of "The Little Review" being burned or otherwise destroyed before they could arrive at their subscribers. We are seeing the same rhetoric used by conservative lawmakers today that was used in the early 20th century against Margaret Anderson, despite no evidence to support it. They argued that if young girls read "obscene literature," they would turn to a life of immorality, prostitution, or partner with people not approved of by their parents.   "She was not a saint, but there were a lot of things to admire about her courage and her sense of agency." —  Adam Morgan   Connect with Adam Morgan: Professional Bio: https://adam-stephen-morgan.com/  Twitter: https://x.com/adamm0rgan  Book: https://adam-stephen-morgan.com/a-danger-to-the-minds-of-young-girls/  Bluesky: https://bsky.app/profile/thefrontlist.org  Instagram: https://www.instagram.com/adamm0rgan    Connect with Therese: Website:  www.criticallyspeaking.net Bluesky: @CriticallySpeaking.bsky.social Instagram: @criticallyspeakingpodcast Email: theresemarkow@criticallyspeaking.net   Audio production by Turnkey Podcast Productions.

    Elizabeth Burch: Pain Brokers: Exploiting Women by Mass Torts

    In this episode, Therese Markow and Elizabeth Burch discuss Elizabeth's new book, "The Pain Brokers: How Con Men, Call Centers, and Rogue Doctors Fuel America's Lawsuit Factory," which exposes a scheme where con artists, attorneys, and rogue doctors exploited women through mass torts involving pelvic mesh implants. Elizabeth explains how mass torts differ from class actions and explains how attorneys earn contingency fees. Throughout the episode, they discuss the ways in which the scheme was perpetuated and how vulnerable women were exploited by a data breach in India.     Key Takeaways: A tort is a harm, such as a punch or a car accident. A mass tort is when those harms happen on a large scale.  Mass torts can be a goldmine for lawyers (and there is a convention held twice a year regarding mass torts in Las Vegas). This can be concerning as more states are allowing law firms to be owned, even partially, by non-lawyers.  Many of the women involved with this mass tort were conned by people who had their specific information, including birth dates, surgery dates, and other medical information. It created a lot of confusion for many.    "You can imagine that your scam detector would probably go off if someone called you and asked you for that information. But if someone calls you and they already know your birth date and the name of your implanting doctor and the type of mesh that you have and exactly when you had the surgery and where you had the surgery, then all of a sudden it feels a lot more legitimate." —  Elizabeth Burch   Connect with Elizabeth Burch: Professional Bio: https://www.elizabethchambleeburch.com/about  Website: https://www.elizabethchambleeburch.com/  Bluesky: https://bsky.app/profile/eburch.bsky.social    LinkedIn: https://www.linkedin.com/in/elizabethcburch/  Instagram: https://www.instagram.com/elizabethcburch/  X: https://x.com/elizabethcburch  Facebook: https://www.facebook.com/ECBurch/   Pre-Order The Pain Brokers: How Con Men, Call Centers, and Rogue Doctors Fuel America's Lawsuit Factory here: https://www.simonandschuster.com/books/The-Pain-Brokers/Elizabeth-Chamblee-Burch/9781668068861    Connect with Therese: Website:  www.criticallyspeaking.net Bluesky: @CriticallySpeaking.bsky.social Instagram: @criticallyspeakingpodcast Email: theresemarkow@criticallyspeaking.net   Audio production by Turnkey Podcast Productions.
