Please answer a few questions to help my podcast

The microbiome receives lots of attention, but what do we really know? In this episode, Dr. Bobby unpacks whether your gut bacteria are truly the key to preventing disease—or if the science still needs to catch up.

Microbiome buzz is everywhere—from promises of inflammation relief and weight loss to claims about mental health and longevity. But what does the research actually say? Dr. Bobby begins with four essential questions: Is the microbiome important? Does it change based on our habits? Do those changes cause disease? And can restoring it improve our health?

Using his open-minded skeptic lens, Dr. Bobby explains that while mouse studies offer compelling clues—like the famous “fat mouse, skinny poop” experiments showing weight gain linked to microbiome transplants—the same effects haven’t translated reliably in humans. A rare exception is C. difficile colitis. Here, fecal transplants have up to a 90% success rate, with medical societies endorsing this approach (source).

For other conditions like diabetes, rheumatoid arthritis, and Crohn’s disease, microbiome disruptions are well-documented. Still, whether these disruptions cause the illness—or are just innocent bystanders—is unclear. In diabetes, for instance, small studies and reviews show possible improvement in insulin sensitivity after fecal transplants (source) and mixed outcomes with probiotics (source), but nothing rivals the proven power of standard therapies like metformin.

Dr. Bobby also explores whether lifestyle choices—such as eating more fermented foods, fiber, and taking probiotics—can truly “reset” your microbiome and keep us healthy. The answer? These may enhance diversity and gut health, but current data doesn’t yet confirm long-term disease prevention. He references findings from the NIH Human Microbiome Project (source) and other studies showing how gut bacteria influence immune development, vitamin production, and digestion (source).

He also touches on terminology: probiotics are live bacteria (think yogurt and kombucha), prebiotics are their food (found in beans and whole grains), and postbiotics are beneficial byproducts. Each plays a role, but their direct impact on human disease remains uncertain.

Dr. Bobby closes with this: he enjoys homemade yogurt and sauerkraut, but doesn’t chase expensive probiotic supplements. “It can’t hurt and might help,” he says—but don’t expect probiotics to fully replace conventional treatment. As research evolves, he’ll continue to watch the space closely—and encourages listeners to let him know if this type of deep-dive, still-unsettled topic resonates.

Takeaways:

1. Fecal transplants are a proven, effective microbiome treatment—for C. difficile, not for general wellness.
2. Most microbiome buzz comes from animal studies, and evidence in humans is still preliminary and inconsistent.
3. Eating more fiber and fermented foods likely supports gut health, but won’t replace proven medical treatments.

Can you provide feedback on my podcast (what you like?  what you want more of?  length?  Please answer a few questions here.  

Can a simple habit like flossing really reduce your risk of stroke? In this episode, Dr. Bobby unpacks the headlines sparked by a recent presentation at the American Stroke Association’s International Conference that claimed regular flossing could reduce stroke risk by 20–50%. 

Dr. Bobby begins with a refresher on the importance of stroke prevention. From there, he explores the biological plausibility of a connection between oral health and cardiovascular events. While Americans are fairly diligent about brushing (with 90% brushing once daily and 60% brushing twice a day per YouGov data), flossing habits lag significantly (NIH Oral Health Study—highlighting a clear opportunity if the flossing-stroke link is real.

Dr. Bobby dives into the study behind the headlines, a new analysis from the long-running Atherosclerosis Risk in Communities (ARIC) study, which tracked over 6,000 individuals for 25 years. The preliminary finding: regular flossers had significantly lower risk of ischemic and cardioembolic strokes (Study Abstract). Surprisingly, brushing and dental visits showed no significant benefit in this analysis.

So why isn’t this flossing-stroke connection headline a "five-alarm fire" in medicine? Dr. Bobby explains the limitations: the results were shared via a conference abstract, not a peer-reviewed journal article. Without full access to the data or understanding how many other hypotheses were tested from this large dataset (which has already generated over 2,300 publications), we risk falling into the trap of correlation being mistaken for causation.

To further evaluate the credibility of this association, Dr. Bobby introduces the Bradford Hill criteria—nine principles to assess causality in observational studies. While the biological plausibility is strong and the effect size notable, the study fails on criteria like replication, dose-response, and publication rigor (Bradford Hill Overview).

In closing, Dr. Bobby affirms the benefits of flossing—not necessarily for stroke prevention, but for better oral health, which is valuable in its own right. He shares his personal oral care routine, including flossing nightly and using a water jet, while reminding listeners to stay evidence-informed in their health decisions.

Takeaways
Flossing likely improves oral health, but its role in stroke prevention remains unproven.

Be cautious with headlines drawn from unpublished conference abstracts—they’re a starting point for inquiry, not a reason to change behavior just yet.

 As the holiday season approaches, the question of how much alcohol is too much becomes ever more pressing. What if the festive cheer of a drink or two could be clouded by the potential for long-term health risks? 

Dr. Bobby unpacks the complex and often contradictory research around alcohol, helping listeners navigate the decision: is it best to have none, or is a little okay? By exploring the impacts of alcohol on weight/appetite, heart disease, cancer, sleep, and cognitive health, and by considering personal health types, listeners can make more informed choices about their drinking habits.

 Key Topics Covered:

• Conflicting Headlines and Research:
  Discussing the confusion around alcohol’s health effects, from Gallup poll insights to studies highlighting both potential benefits and risks.

Health Risks Explored:

Weight Gain: Alcohol adds calories and increases appetite, contributing to potential weight gain (study on caloric intake).

Heart Disease: Early studies suggested moderate benefits for small amounts of alcohol, but advanced analyses, like Mendelian randomization, challenge this assumption, not showing a protective effect (study on genetic analysis).

Cancer Risks: Alcohol consumption has been linked to several cancers, including breast and colon cancer.  (WHO fact sheet).

Sleep Impacts: Alcohol disrupts sleep quality, even if consumed earlier in the day (small study on sleep effects).

Cognitive Decline: Even mild drinking shows potential risks for brain health, with larger consumption exacerbating damage (UK Biobank study).

Defining Drinking Levels:
Categories from non-drinker to heavy drinking were clarified, helping listeners identify where they stand (National Survey on Drug Use and Health).

Personal Stories and Practical Decisions:
Dr. Bobby shares his personal experience with holiday indulgence and offers practical strategies for mindful drinking.

Role of Health Types:
Leveraging your health archetype (e.g., Purposeful Path Planner or Contentment Creator) to guide decisions about alcohol consumption.

Takeaways: 

Know Your Limits: For most, keeping alcohol under seven drinks per week minimizes risks without eliminating enjoyment.

As we navigate the complexities of alcohol's impact on health, I share my personal approach of allowing myself up to seven drinks a week, accepting some level of risk for the sake of balance. With the Living Well Aging Strong program, we provide tools to create personalized health plans, empowering you to make choices that align with your lifestyle. Let's embark on this journey together, equipped with knowledge and support, as we strive for imp

Are seed oils the dietary villain social media makes them out to be, or is this just another food fear fad? Join me, Dr. Bobby Dubois, as I unravel the truths and myths surrounding seed oils like canola and safflower. 

There are NO randomized clinical trials comparing people who eat a diet with seed oils vs a diet consisting of non-seed oils like avocado, coconut, or olive.  Since we lack the key studies that we desire, I explore the topic based upon the following questions:

1. Are corn, peanuts, and the vegetables that produce these seed oils bad for you? (no evidence to support this concern)
2. Is the problem getting the oils out of these good vegetables (the extraction and denaturing process)?  Likely not.
3. Is it the contents of the seed oils themselves harmful (e.g., the omega 6 polyunsaturated fats)?  Our bodies need omega 6s and the studies that switch folks from saturated fats to seed oils show no risk of heart disease (and maybe the opposite). No evidence they they raise markers of body inflammation, and don't increase the risk of diabetes.
4. Is the harm related to the heating of the seed oils? Heating seed oils can produce potentially harmful compounds, but so does grilling a steak or salmon.
5. How much seed oil do we consume as we cook food?  Not a lot. 70% of the fat we eat comes from meat (fish, beef, chicken) and not added oils.
6. Are we blaming the wrong food?  Likely this is the key issue as cheap seed oils led to the production of yummy, highly processed, calorie dense foods.  And the problem lies there....
7. Avocado or olive oil costs 5 times what canola/corn oil costs.  Is it worth the cost to switch from seed oils to these non-seed oils? A

Take-home messages:

• i don't fear seed oils
• where they can be a concern is reusing oils over and over in a deep fat fryer where potentially worrisome compounds can accumulate
• If you have symptoms that bother you, perhaps do an N-of-1 trial of removing them from your diet.
