Tops Trends from the 2024 Integrative Healthcare Symposium
Last month, the Integrative Healthcare Symposium (IHS) reconvened in New York City, drawing a wide range of professionals from across the healthcare spectrum. This year's program included a melting pot of ideas, showcasing groundbreaking advancements and innovative approaches in integrative medicine.
From the nuanced understanding of the microbiome's role in human health to the application of artificial intelligence in diagnosing and treating diseases, the symposium was abuzz with new and exciting concepts. Epigenetics and brain health also emerged as key areas of interest, along with personalized nutrition plans.
In this overview, we delve into the standout trends from the 2024 symposium, illuminating the ideas reshaping the future of medicine.
Addressing the Gut-Brain Connection
The gut-brain axis was a central theme of the conference. During her presentation, Elisa Song, MD, argued that the rising rates of neuropsychiatric disorders align with the increasing popularity of ultra-processed foods containing chemical additives and added sugars that can disrupt the gut microbiome.
"Our gut microbiome is our second brain, and what we eat directly affects our mood, behavior, and overall health,” said Dr. Song, an integrative pediatrician and pediatric functional medicine expert.
Dr. Song explained that stress, lack of sleep, and dehydration can all decrease microbial diversity in the gut, which can impact brain health. She said lifestyle choices like consuming more fiber and fermented foods, optimizing sleep, exercise, and meditation increase microbiome resilience and help decrease the risk of pediatric neuropsychological conditions.
“Our enteric nervous system can live without our brain,” said Dr. Song. “Our brain cannot live without our enteric nervous system.”

Betsy Greenleaf, DO, FACOOG, FACOG, took the concept a step further, framing her talk around the relationship between the gut microbiome, brain, and vagina.
According to Dr. Greenleaf, the gut microbiome and vaginal microbiome are connected to the brain via a feedback loop through the vagus nerve, which can dampen all processes of reproduction, including sex drive. In addition, mental health problems like depression and anxiety raise cortisol, which increases the risk of vaginal yeast infections.
“It becomes very complicated, and it's hard to know where to start,” said Dr. Greenleaf. “But I think the simplest explanation is, if you're mentally balanced, and your gut is balanced, and the vagina is balanced, everything will be working properly.”

Exploring the Epigenetics of Longevity
“All biohacking techniques make a promise,” said Kenneth R. Pelletier, MD, after being named the 2024 Visionary Award recipient. “But none of them make much of a difference.”
According to Dr. Pelletier, Clinical Professor of Medicine, Family and Community Medicine, and Psychiatry at the University of California School of Medicine, San Fransisco (UCSF), it’s unequivocally clear that the next decade will see breakthroughs in biochemistry and bioengineering that extend life expectancies to 120 years or more. We just aren’t there yet.
What we do have today is strong research linking genetic expression to external factors like diet and lifestyle. And the existence of communities with exceptionally long-lived individuals, known as blue zones, provides real-world evidence of the potential for extended lifespans, according to Dr. Pelletier.
Those living in blue zones share a group of characteristics that Dr. Pelletier calls the "Divine Dozen," comprising lifestyle and diet choices that are believed to encourage favorable gene expression. These communities, he explained, are proof that simple lifestyle and diet choices have the potential to encourage positive gene expression and prevent disease.
“This is happening right now; these are communities where people live on a regular basis to 115 or 120 years old, and they have for decades,” said Dr. Pelletier. “And what’s striking is they don’t have any of the biohacking technology that we talk about.”

In the face of increasing rates of autoimmunity, research on epigenetics—how interactions with the environment, including diet, stress, and exposure to chemicals, can alter gene expression—has shed light on how to prevent and treat the mysterious conditions that follow it, according to Jeffrey Bland, MD, FACN, CNS.
During his presentation, Dr. Bland, the founder of the Functional Medicine movement, discussed the concept of epigenetics and how it may determine the future of one’s health more than genetics alone.
This idea challenges our conception of what autoimmune disease is, he explained. Yes, autoimmunity involves some natural processes in cellular biochemistry, but we now know exogenous forces also trigger those reactions.
"I don't think that we wake up one morning and suddenly become allergic to ourselves, particularly the most innate thing we have, which is our genes," said Dr. Bland. "So, what happens if what we've been calling autoimmune disease is really a reaction to things that are not us?"
Just as external factors like diet and lifestyle can contribute to autoimmune disease, they can also prevent it, Bland said. And perhaps the most significant link between diet and immune function is the gut microbiome. "Nutrition and the microbiome are not just part of the conversation about health—they are central to it,” he said.

Preventing Cognitive Decline with Integrative Interventions
Physicians are led to believe that β-amyloids are the cause of Alzheimer's disease, which can only be treated with pharmaceuticals designed to rid the brain of the peptides, but according to David Perlmutter, MD, FACN, ABIHM, that may not be the case.
Historical and recent research suggests that beta-amyloid might have protective roles, such as being an antimicrobial peptide or a response to infections (e.g., herpes simplex virus), explained Dr. Perlmutter, board-certified neurologist and author of Grain Brain, during his presentation. “Maybe amyloid is there to help us out,” he said. “Maybe the enemy of my enemy is my friend.”
Emerging data indicates that addressing metabolic health with lifestyle interventions is more effective at preventing cognitive decline and Alzheimer's disease than reducing levels of β-amyloids. According to Dr. Perlmutter, Alzheimer's disease begins decades before symptoms like memory loss become apparent, and the changes occurring in the brain leading to Alzheimer's are primarily metabolic.
"Brain glucose hypometabolism is a dysfunction of the brain's ability to metabolize or utilize glucose that happens potentially decades before the clinical manifestation of memory begins to fail," he said.
Dr. Perlmutter estimated that leveraging metabolic health improvements in individual medical care could prevent up to 70 percent of Alzheimer's cases. “While it's important to pull people out of the river,” he said, “it's far more important to find out why they're falling in the first place."

In another presentation, Shai Efrati, MD, Director of the Sagol Center for Hyperbaric Medicine and Research at Shamir (Assaf-Harofeh) Medical Center in Israel, discussed the hyperoxic-hypoxic paradox, a specific protocol in hyperbaric oxygen therapy that activates the body's regenerative processes, with a particular focus on the brain.
The research on the hyperoxic-hypoxic paradox focuses mainly on age-related cognitive decline. However, it’s also been shown to improve several other conditions, including post-traumatic stress disorder (PTSD), fibromyalgia, and erectile dysfunction, Dr. Efrati explained.
“We should be looking at the brain just like every other tissue in the body,” said Dr. Efrati. “It can be repaired and regenerated, and to do that, it doesn’t necessarily need to be something chemical we put in our body.”

Incorporating Artificial Intelligence into Clinical Practice
Healthcare is becoming increasingly personalized, predictive, and precise thanks to the convergence of genomics, AI, and digital health tools, according to Daniel Kraft, MD, physician-scientist and Founder of IntelliMedicine.
"We're moving from a world of reactive to proactive medicine, where the future is not about waiting for disease to happen but preventing it in the first place,” he said.
During his keynote presentation, Dr. Kraft discussed the potential of artificial intelligence (AI), wearable devices, genomics, digital health platforms, 3D printing, and virtual reality to transform medicine. These technologies, he said, have the power to detect disease earlier, personalize treatment protocols, decrease time spent on administrative tasks, and improve access to healthcare.
"We need to take exponential steps, not incremental ones in healthcare innovation,” Dr. Kraft explained. “The future is already here; it's just not evenly distributed."
LISTEN: The Future of Integrative Healthcare
In a live interview at the conference, Mark Hyman, MD, also emphasized the potential of emerging technologies, such as machine learning, AI, and biosensors, to revolutionize healthcare by enabling personalized and predictive health models.
"The future of medicine lies not just in treating diseases, but in understanding and optimizing the unique health profile of each individual,” he said.
During the interview, Dr. Hyman discussed why integrative and functional medicine should be harnessing these technologies to improve patient care, emphasizing the importance of empowering patients and healthcare providers through data-driven insights for optimizing health.
The conversation also touched on the challenges and opportunities presented by these technologies, including accessibility and the potential to significantly lower healthcare costs while improving outcomes.
