110 - Rapamycin, Genes on Sale, and Flowing Through Jazz - HealthHippieMD Week In Review

There will be no newsletter next week as I gather with family and friends to celebrate my son's wedding. The newsletter will resume on Sunday, October 6.

Forever in Your Food

PFAS, or "forever chemicals," are increasingly found in food, raising concerns about long-term health impacts. These synthetic substances, used in products like nonstick cookware and food packaging, resist breakdown, contaminating farmland through sewage sludge fertilizer. Linked to cancer, liver disease, and developmental issues, PFAS can accumulate in food, particularly in items like milk, eggs, and seafood. While the FDA's tests show low levels in most foods, the full extent of contamination remains to be seen, and regulatory gaps leave questions about how safe our food supply truly is.

Leaky Gut Instinct

Emerging research suggests long-term COVID-19 in children might be linked to gut permeability, or "leaky gut." Dr. Lael Yonker, a pediatric pulmonologist, has launched the first clinical trial testing larazotide, a drug to tighten intestinal walls. This trial seeks to address symptoms such as headaches, gastrointestinal pain, and attention issues in children with long-term COVID-19. While long Covid research has primarily focused on adults, Yonker's trial could provide an essential treatment option for young patients, possibly offering a breakthrough in combating this debilitating condition.

Plastic Fantasy

In a lawsuit backed by ProPublica's reporting, California accuses ExxonMobil of deceptive marketing regarding its chemical recycling process, pyrolysis. The oil giant claims the technology transforms plastic waste into reusable products, such as fruit cups, but evidence shows less than 0.1% of the recycled content ends up in new products. Despite this, ExxonMobil advertises 30% recycled content using controversial accounting methods. The lawsuit likens this practice to past tobacco industry deceptions, calling for billions in penalties to fund public education and sustainability efforts.

Genes on Sale

Remember That DNA You Gave 23andMe? - The Atlantic explores the potential sale of 23andMe and its genetic data, raising concerns about DNA privacy. As the company struggles financially, with stock declines and leadership upheavals, its most valuable asset—customers' genetic information—may be sold. This creates uncertainties about how future owners might use sensitive data, with risks extending beyond current privacy policies. Insurance companies, law enforcement, and other third parties could exploit the DNA data for profit or surveillance. The article underscores that once DNA is shared, it cannot be fully controlled, posing long-term consumer risks.

AI Doctor's Notes

As physicians face overwhelming patient messages, AI tools like MyChart's "In Basket Art" are stepping in to draft responses. These tools use AI models to mimic doctors' voices, providing medical advice or administrative replies. Though many hospitals embrace efficiency, concerns over transparency and potential errors in AI-generated responses grow. Experts worry about automation bias, where physicians may rely too much on AI, risking patient safety. As AI edges into clinical decision-making, ethical questions arise about the role of technology in personal doctor-patient communication. That Message From Your Doctor? It May Have Been Drafted by AI - The New York Times (gift article).

The Rapamycin Gamble

Rapamycin, a drug traditionally used as an immunosuppressant, has gained attention in the longevity community for its potential anti-aging benefits. Early studies in animals, including mice, show promise, suggesting the drug can extend lifespan by inhibiting the mTOR complex, which is linked to cellular health. However, human studies remain inconclusive, with mixed results and limited long-term data. While some users report improvements in energy, reduced inflammation, and other minor health benefits, skeptics caution about the drug's potential risks, such as immune suppression. The quest for a longer, healthier life continues—cautiously. Rapamycin and Anti-Aging: What to Know - The New York Times (gift article).

A Recipe for Health

How UTSW's Food as Medicine Program Is Revolutionizing Physician Education - D Magazine explores the Food as Medicine program at UT Southwestern (UTSW) and how it is transforming physician education by incorporating culinary medicine into medical training. Spearheaded by Dr. Jaclyn Albin and Program Director Milette Siler, the initiative teaches medical students and residents how to use food to combat chronic illness. With cooking classes and real-world nutrition lessons, physicians learn to help patients manage conditions like diabetes and heart disease through diet. The program partners with local communities and aims to make healthy eating accessible and culturally sensitive, tackling health outcomes and social isolation. I am currently enrolled in a similar class offered online: Culinary Health Education Fundamentals (CHEF) Coaching—The Basics-Overview | Continuing Education Catalog. (thanks, Amy!).

Flowing Through Jazz

In a study of jazz musicians, researchers used EEG scans to explore the brain activity behind entering a "flow state," a heightened, effortless creative focus. Jazz guitarists of varying experience levels improvised while their brain activity was recorded, revealing that more experienced musicians frequently entered flow. Brain scans showed reduced activity in areas associated with cognitive control, suggesting that expertise enables performers to "let go" mentally, allowing creativity to flourish. This research sheds light on how mastery and relaxed focus foster spontaneous innovation. Brain Scans of Jazz Musicians Reveal How to Reach a Creative 'Flow State' | Scientific American.

Empathy: A Team Sport?

Empathy isn't just an individual endeavor—it's socially driven. Research shows that empathy flourishes when it's a group norm, not just a personal skill. Programs like "empathy cafes" and classroom workshops reveal that structured dialogues and reflective listening can foster understanding, even across deep divides. Neuroscience supports this: empathetic behavior lights up specific brain regions, and witnessing empathy in others boosts our empathetic response. The key takeaway? Empathy thrives when nurtured in communities, showing that togetherness can make the cognitive challenge of empathy more manageable and rewarding.

10 Myths in Nutrition

An interesting article for both the myth-busting and the experts consulted: 10 Nutrition Myths Experts Wish Would Die (gift article)

The Microbiome and Thermoregulation

This summary article had a wealth of provocative information:

  1. The presence or absence of certain bacteria was associated with the body's temperature response in sepsis (in both humans and mice).
  2. Mice without a microbiome have a lower basal body temperature than conventional mice.
  3. The administration of antibiotics lowers basal body temperature.

The authors of the study opine that changes in the microbiome may account for the reduction in basal body temperatures of humans over the last 150 years: Gut Microbes Control the Body's Thermostat

I learned a few new things about the neuropsychological underpinnings of deja vu in the article: What is déjà vu? A psychologist explains this common but creepy phenomenon.

More Terramation

It seems like stories about human composting are everywhere. This article was in Slate: Composting offers a greener way to dispose of human remains.

Brain Cells on a Chip Learn to Play Pong

I found this article on brain-machine interfaces: Brain cells on a chip learn to play Pong within 5 minutes. Although the title is a bit sensational, I still find the concept disturbing.

Omega-3 Fatty Acids and Brain Health

In a new study, Omega-3's Linked to Improved Brain Structure and Cognition at Midlife, , the authors opined increasing omega-3 fatty intake might help preserve brain health and cognition in middle age. We still don't understand the mechanism of how omega-3 fatty acids work in the brain. My guess is the mechanism involves our endogenous endocannabinoid system, as I mentioned in 006 - Loneliness, Mucus, and Cannabinoids - HealthHippie Week In Review.

Return on Investment for Employee Wellness Programs

Michael Greger released the first video in a series focused on the business case for offering wellness programs in corporate environments: The Return on Investment (ROI) for Employee Health and Wellness Programs. His take after reviewing the literature: $3 returned for every $1 spent.

Rethinking Healthy Eating in Terms of the Microbiome

I loved the manuscript, Rethinking healthy eating in light of the gut microbiome. The manuscript synthesizes a wide range of information from around the world and makes recommendations on what constitutes healthy eating by promoting a healthy gut microbiome. I will be referring to this paper for a time to come.

The Rocky Road of Aspartame

I've had a long-standing interest in non-nutritive sweeteners. Aspartame, only one of many artificial sweeteners, is a multi-billion dollar product. Aspartame: Decades of Science Point to Serious Health Risks is a compilation of the primarily negative data on the multi-billion dollar substance. For a less critical view, see: The_History_of_Aspartame

Think You Are Responsible with your Recycling? Think again.

The article Big Plastic Wants You to Think You Can Recycle Your Yogurt Container, was eye-opening for me. Only a tiny fraction of plastics are recycled, and there is incredible resistance to doing so, given the cost. The take-home point of the article for me: buy fewer products made of ANY plastic.

Our Pets, Our Microbiome

I enjoyed reading Does owning a pet boost your gut health? on how humans and our animal companions swap bacteria -likely beneficial to our overall health and well-being. The one downside of the article is not being able to unsee the phrase "fecal patina."

Behold Envy, The Happiness Killer

Arthur Brooks tackles the topic of envy in the article How to Stop Being So Envious. The article touches on social comparison, social media, and the importance of authenticity. In addition, he offers a few practical suggestions to minimize the role of envy in your life.

Making Better Use of Antidepressants

I learned a lot from the article, How to make better use of antidepressants (pay-wall). I did not realize that 10-15% of the population is on antidepressants, many for a very long time. With the serotonin theory of depression recently called into doubt coupled with a re-examination of this class of drug's efficacy (only about 15% response rate, mainly in severely depressed), it is likely time to reexamine our overuse of these medications, especially in the elderly.

New Evidence Linking the Microbiome to Rheumatoid Arthritis

The 2017 paper, Evidence of the Immune Relevance of Prevotella copri, a Gut Microbe, in Patients With Rheumatoid Arthritis, hypothesized that a protein produced by a common gut bacteria, Prevotella copri, could trigger the immune system and lead to arthritic inflammation. A new study summarized in New evidence linking gut bacteria with rheumatoid arthritis development provides further evidence supporting the 2017 hypothesis.
