Podcast Summary: The Dr. Josh Axe Show – What's REALLY Causing This American Epidemic...

Host: Dr. Josh Axe
Date: August 25, 2025

Brief Overview

In this episode, Dr. Josh Axe investigates the dramatic rise of autism diagnoses in American children, delves into the possible root causes—from environmental, genetic, and maternal factors to medications and toxins—and offers practical, natural strategies for prevention and healing. Leveraging both clinical experience and scientific research, Dr. Axe aims to empower parents and listeners with up-to-date knowledge while advocating for more nuanced, open-minded discussions around autism's origins and treatment.

Key Discussion Points & Insights

1. Autism Rates & Diagnostic Evolution

• Statistics: In the US, 1 in 31 children are diagnosed with autism (00:27), a fivefold increase since 2000. This contrasts with global rates of about 1 in 100.
• Diagnostic Categories: Dr. Axe suggests autism diagnoses should be split into “high functioning” (e.g., Asperger’s) and “low functioning” autism, noting vast differences in language, IQ, independence, and co-morbidities (04:00–08:00).
  • Quote:
    “There is a pretty massive chasm in difference between somebody like Elon Musk, who ... has Asperger’s, and some of the kids my mom was taking care of ... who had no speech ... into their teenage years.” — Dr. Axe (05:40)

2. The Five Root Causes of Autism (08:31–30:30)

1. Vaccinations & Immune Triggers (08:31–13:13)

• Dr. Axe shares clinical anecdotes where parents observed dramatic behavioral changes post-vaccination.
• Critiques the lack of long-term, independent vaccine safety studies and highlights advocates like Robert F. Kennedy Jr.
  • Quote:
    “As Robert F. Kennedy, Jr. pointed out, the science isn't settled, it's silenced.” — Dr. Axe (12:25)
• Notes, while not the only factor, vaccines may contribute to immune dysfunction and gut-brain inflammation in susceptible children.

2. Genetics & Maternal Autoimmune Risks (13:14–19:34)

• Heritability estimates for autism run between 50–90%. Certain gene mutations and epigenetic triggers (e.g. maternal autoimmune disease) raise risk.
• Emphasizes gut health and immune health in pregnancy as crucial.
  • Quote:
    “Moms being sick from environmental factors like having chronic infections ... can influence these epigenetics.” (15:58)
• Studies cited:
  • Taiwan: 33% higher autism risk with maternal autoimmune disorders
  • Denmark: 16% increased risk from maternal autoimmune diseases
  • CHARGE study: 46% higher likelihood of developmental issues

3. Maternal & Child Gut Microbiome and Immune Activation (19:35–24:44)

• Imbalance in gut bacteria (dysbiosis) and maternal microbiome passed to the child increase risk.
• Animal and human studies link disrupted gut flora to autism-like behaviors and symptoms.
  • Quote:
    “I’ve taken care of 1000 children plus with autism and all of them have gut and digestive issues, almost all of them.” (19:48)
• Recommends probiotics and gut health support for prevention and healing.

4. Medications: Acetaminophen (Tylenol), Antibiotics, Others (24:45–28:09)

• Johns Hopkins study: Acetaminophen use in pregnancy linked to >300% higher autism/ADHD risk.
  • “There is a link between Tylenol use during pregnancy and increased risk of both autism and ADHD.” (25:47)
• Antibiotics disrupt gut flora; early-life use raises autism and allergy risks.
• Mechanism: Both can fuel leaky gut and neuroinflammation, undermining brain development.

5. Environmental & Chemical Exposures (28:10–30:40)

• Air pollution, heavy metals (mercury, lead, arsenic), pesticides (especially glyphosate), and endocrine disruptors (BPA) implicated.
  • “For every moderate increase in NO exposure, the odds of autism went up by about 7%.” (28:53)
  • High BPA triples risk in boys.
• C-section delivery, maternal obesity/diabetes, chronic infection, and nutrient deficiencies (D, folate) also increase risk.

3. Natural Strategies for Healing Autism (31:20–42:00)

Avoidance of Root Causes

• Proactive avoidance: Reduce exposures to potential triggers before and during pregnancy, and early childhood.

1. Therapeutic Diet & Nutritional Intervention (32:20–36:00)

• Foundational step: Gluten-free, casein-free diets yielded substantial improvement in speech and behavior.
  • “With my patient Ben, who went from about ... four words to 40 words over a matter of a few weeks, that's what we did.” (32:45)
• Anti-inflammatory, gut-healing diets recommended:
  • Cooked meats, non-nightshade veggies, easy fruits, healthy fats, white rice (congee style).
  • Focus: Find “vegetables they hate the least,” and adapt to picky eating common in ASD.

2. Targeted Supplementation (37:00–38:00)

• Frequently low: Zinc, magnesium, vitamin D, probiotics, digestive enzymes, methylated B vitamins, omega-3s, mitochondrial supports.
• Chinese herbal support as digestive tonics (e.g., ginger, chamomile).

3. Therapy & Behavioral Interventions (38:22–38:48)

• Applied Behavioral Analysis (ABA), speech therapy, and social skills training are highly beneficial alongside dietary and supplement strategies.

4. Functional Medicine & Testing (38:48–40:30)

• GI testing (for pathogens, dysbiosis), heavy metal screens, food sensitivity, and micronutrient tests guide individualized interventions.
• Stool-based probiotic therapy (FMT) and soil-based organisms are explored.

5. Hyperbaric Oxygen Therapy (HBOT) (40:31–41:20)

• Dr. Axe describes “amazing improvements in language and focus” with HBOT, especially when paired with diet and supplements.
  • Recommends 40–80 sessions at 1.5–2.0 ATA for optimal results.

6. Stem Cell Therapy & Additional Approaches (41:21–42:40)

• Stem cell therapy (not available in US clinics) shows promise for severe ASD and gut/immune repair.
• Other adjuncts: Occupational therapy, detoxification strategies (glutathione, N-acetylcysteine, binders, Epsom salts).

Memorable Moments & Notable Quotes

• On the need for diagnostic clarity:
  “I think we might want to say something instead like ... one in 60 children have classic autism and one in 90 have Asperger's. ... Quote them separately.” (07:30)

• Parental validation:
  “I do want to say, I think that we have far too many people, doctors, especially in pharmaceutical companies, have completely written off those parents who have experienced that.” (10:26)

• On multifactorial causation:
  “There isn’t likely one single cause of autism. It’s multifactorial ... all of these can damage the gut-brain connection and harm the immune system that can contribute to autism.” (42:30)

• On hope and healing:
  “While you can't in many cases completely reverse an autism diagnosis, you can sometimes, and at the very least, you can see great improvements.” (31:15)
