We know oral health matters, but most of us don’t give it the respect it deserves . . today might change that.

Because on this episode of feelgoodery, Kyle sits down with Dr. James Goolnik, one of the world’s leading holistic dentists, to talk about what your mouth can reveal about the rest of your body, why some early cavities don’t have to end with a drill.

PLUS - which popular oral care trends are actually worth it (and which are marketing BS).

In this episode:

• What holistic dentistry is, and how it differs from regular dentistry
• Why Dr. James says your dentist can spot signs of over 57 health conditions in the mouth - and how he’s spotted pregnancies before his patients knew
• How stress and poor sleep show up in your mouth (clenching, grinding, and the signs you can check yourself when you wake up)
• Sleep apnea warning signs, and why to check your overnight oxygen on your wearable
• How early tooth decay can be reversed - and why snacking frequency matters as much as sugar
• Can you rebuild enamel? Hydroxyapatite toothpaste, nano vs. micro, and why you shouldn’t rinse after brushing
• Is sparkling water bad for your teeth?
• Receding gums, CoQ10, and whether red light devices for the mouth actually work
• How to choose a toothpaste: abrasiveness (RDA), whitening, charcoal, fluoride and hydroxyapatite
• Should you wait 30 minutes to brush after eating?
• Rapid fire: charcoal toothpaste, oil pulling, mouth taping and tongue scraping (and why he says to scrape before bed)
• The one small change that can make the biggest difference to your oral health
• Today’s feelgood thing

The internet is full of wellness trends, and some of them are wild. In this quick episode of feelgoodery, Kyle Buchanan looks at two you might be seeing right now, standing on Epsom salts for better sleep and the Japanese walking method, and sorts out what's actually backed by research, what isn't, and whether either one is worth your time

In this episode:

• The Epsom salt foot trend: what people are doing, what they're claiming (lower cortisol, less inflammation, better sleep), and where the evidence falls short
• Why a slow, sensory bedtime ritual can still improve your sleep - even if the explanation going around online isn't correct
• The Japanese walking method (interval walking training): how to do it - 3 minutes at a comfortable pace, 3 minutes fast, for 30 minutes
• What the original Japanese studies found
• Kyle's ratings
• Today's feelgood thing:

Studies mentioned:

• Effects of High-Intensity Interval Walking Training on Physical Fitness and Blood Pressure in Middle-Aged and Older People — the original Japanese study (Nemoto et al., Mayo Clinic Proceedings) comparing no walking, steady moderate walking, and interval walking

Yes, it's really called that, and yes, it comes from the same word you're thinking of. Spermidine is becoming bigger and bigger in the longevity world, and for good reason.

Today, Kyle's breaking down what spermidine actually is, why researchers are excited about its link to a cellular "clean-up" process called autophagy, whether it's connected to Japan's remarkably high number of centenarians, and which everyday foods (yes, including one very sticky Japanese staple) are the richest natural sources.

Plus: is the supplement version worth trying, or is food still your best bet?

In this episode:

• What spermidine is
• The autophagy connection: your body's cellular clean-up crew, and how spermidine may support it (without replacing fasting)
• Why natural spermidine levels decline with age, and what that might mean for healthy aging
• What the actual human research shows so far, including a small BDNF study and a larger observational trial, and where the evidence is still thin
• The best natural food sources of spermidine (natto, wheat germ, mushrooms, legumes, aged cheese), for people who will never touch a supplement
• Kyle's honest take on spermidine supplements, and why his current stance is "food first, supplement curious"
• Today's feelgood thing: the small, smug joy of being right

Studies mentioned:

• Nutraland rice germ extract pilot study coverage
• Longitudinal association of dietary spermidine with hepatic function indexes and cardiometabolic traits (European Journal of Nutrition)
• Effects of Spermidine Supplementation on Cognition and Biomarkers in Older Adults (JAMA Network Open)

Feeling small, scared, or checked-out lately? You're not imagining it . . . and you’re also not failing because of it. In this Season 5 premiere of feelgoodery, Kyle Buchanan breaks down why the brain defaults to passivity when bad news keeps piling up (AI anxiety, rising costs, the state of the world), and gives five practical, science-backed ways to climb out of it - from the gut-brain connection to a tough love talk, and a perspective shift that might make all the difference.

In this episode:

• Why feeling powerless right now isn't a personal failing - the psychology passivity
• The "control what you can control" method: small, immediate actions that retrain your brain out of shutdown mode
• How your gut microbiome influences anxiety and mood via the vagus nerve, and what a Stanford fermented-food study found
• The real cost of staying small and scared, and why empaths especially need to hear this one
• The reminder that might make all the difference
• Today’s feelgood thing, and why 5HTP might be something to consider

Studies mentioned:

• Learned Helplessness at Fifty: Insights From Neuroscience Maier & Seligman's reinterpretation of their own landmark theory, showing passivity is the brain's default response, not something learned
• Gut-microbiota-targeted diets modulate human immune status — the Stanford (Sonnenburg Lab) fermented-food trial, published in Cell
• Fermented Foods, Neuroticism, and Social Anxiety: An Interaction Model — the ~700-person survey on fermented food intake and social anxiety

We live in a time where we've never had more tools to improve our health.

Wearables. Supplements. Peptides. Longevity clinics. Clean eating. Sleep trackers. AI-powered health advice.

But what if the pursuit of "optimal health" is actually making some of us less healthy?

Today, we're exploring where the line is between building healthy habits... and becoming trapped by them.

We're covering:

• The hidden downside of tracking every health metric
• When "clean eating" quietly becomes an unhealthy obsession
• Why perfect sleep might not always be worth chasing

If you are feeling a sense of urgency all the time, and that you are constantly falling behind . . . you are not alone.

Modern life trains us to be urgent.

We are also doing things to our own biology that is exacerbating this urgency.

So today, I'm taking about key considerations to counteract that feeling, so we feel calmer and have greater agency over our lives.

In this episode you'll learn:

• Why your breathing pattern directly affects your nervous system and stress response
• How caffeine may be increasing feelings of urgency without you realizing it
• The surprising connection between posture, body language, and emotional state
• Why eating too quickly affects both digestion and your nervous system
• How magnesium influences stress resilience and emotional regulation
• Why even mild dehydration can increase cortisol levels
• The neuroscience behind boredom, and why your brain actually needs it
• Practical ways to feel less overwhelmed in everyday life
• Today's feelgood Thing ✨

This episode is for you if...

• You constantly feel overwhelmed or behind
• Your brain never seems to switch off
• You're looking for natural ways to reduce stress and anxiety
• You want practical nervous system regulation techniques backed by science
• You're trying to create a calmer, healthier life

Today we're revisiting one of the most popular episodes of last year, because it's a tool I continue to use today that's made a notable difference.

Today's episode is for the days when you’re feeling stuck, or are feeling so overwhelmed that your brain can't make a single decision. . .

Maybe work is piling up, or maybe it’s just a boring laundry day that’s draining you. Either way, you’re not quite sure how to break out of it.

Today, I'm gonna break down a perspective shift that’s been helping me lately, a way to step out of the stress, the what-ifs, or the boredom, and see everything with fresh eyes. Because when you can shift your perspective—even just a little—it can make life feel just a little easier.

We’re covering:

• Perspective shift for your consideration
• The ripple effect of that perspective shift
• Why even the boring, mundane moments matter in the bigger picture
• How to use this tool in daily life—no matter what you’re dealing with

If you’ve ever found yourself caught up in the noise of your own thoughts, this one’s for you.

And if this shift clicks for you? Amazing. If not, that’s okay too. As always, take what you need and leave the rest.

We all try do our best (most of the time).. drink water, eat our veggies, take the occasional supplement . . .

But what if some of the things we're doing for our health could occasionally be working against us?

Today, we're breaking down some of the lesser-known ways good health habits can sometimes produce unintended results - and why timing, dosage, and context matter more than most people realize.

We're covering:

• Why taking Vitamin C after a workout may not always be the best idea
• The surprising downside of eating too many thyroid-popular nuts
• The smoothie ingredient that recently sparked concern online
• How a common immune-support supplement can create a different nutrient deficiency
• The hidden risk of drinking too much water too quickly
• Why health headlines often miss the nuance
• How to get the benefits of healthy habits without accidentally sabotaging your efforts

Plus... today's feelgood thing.

If you've ever wondered whether you're doing too much of a good thing, this episode is for you.
