At CES last week, The Spoon hosted a panel of experts to discuss the role of personalized nutrition in addressing critical global health challenges, including obesity, diabetes, and chronic diseases.
Moderated by nutrition expert Carolyn O’Neil, the panel featured Noosheen Hashemi of January AI, Ranjan Sinha of Digbi Health, and Matt Barnard of OneBio. Together, they delved into how innovations in artificial intelligence, microbiome science, and biotechnology are transforming how we eat and improve our health.
O’Neil began the session by highlighting the significant impact of diet-related illnesses on public health and the increasing reliance on pharmaceutical interventions, such as GLP-1 drugs like Ozempic. While these medications offer effective solutions for managing conditions like obesity and diabetes, the panelists stressed the importance of addressing root causes, including poor dietary habits, fiber deficiencies, and the lack of personalized guidance.
Ranjan Sinha, founder of Digbi Health, emphasized the critical role that genetics and the gut microbiome play in metabolic health.
“Food has been the cause of many illnesses, but it can also be the cure,” Sinha explained. Digbi Health leverages advanced technology to analyze genetic data, gut microbiome profiles, and telemetry from wearable devices to create customized wellness plans.
Sinha also underscored the untapped potential of microbiome research, describing it as the “next pharmaceutical frontier.” He likened its trajectory to the evolution of electronics, predicting that microbiome-based treatments will dominate healthcare in the coming decades.
“Think about where electronics were in the 1990s, and then the leap to smartphones in the 2000s,” he said. “That’s where microbiome science is headed. In the next 15 to 20 years, your gut could effectively function as a pharmaceutical factory, producing compounds to prevent and treat illness.”
Both Sinha and Matt Barnard highlighted the essential role of fiber in health, directly linking it to the microbiome’s function. By nourishing the microbiome with the fibers it requires, they argued, we could unlock its potential to prevent and even reverse chronic diseases.
Barnard compared the importance of fiber to the early discoveries of vitamins and minerals, signaling a paradigm shift in how fiber is viewed in relation to health.
“One hundred years ago, we didn’t know the importance of vitamins and minerals,” Barnard noted. “Now, deficiencies are rare. The same transformation is happening with fiber. As we learn more, it will revolutionize our approach to chronic disease and metabolic health.”
Noosheen Hashemi, CEO of January AI, agreed with Barnard and Sinha on fiber’s vital role in supporting the human microbiome.
“One of the biggest drivers of inflammation in our collective microbiome is the lack of fiber,” she explained. “Our ancestors, just 12,000 years ago, consumed 100 to 150 grams of fiber daily. Today, our intake is drastically lower. Add to that antibiotics and other factors, and we’re collectively in a state of dysbiosis. It’s essential to ensure people get enough fiber.”
Hashemi also shared insights into January AI’s innovative technology, which predicts a food’s impact on blood sugar using a simple photo of the meal. By analyzing millions of data points, the AI can forecast blood sugar responses to meals, even without requiring wearables like glucose monitors.
The panelists collectively predicted a future where pharmaceutical interventions are complemented by greater reliance on dietary strategies. These strategies will increasingly be informed by technologies capable of analyzing a person’s biomarkers in near real time.
This panel left me wondering if we might see a more significant emphasis on fiber by Americans who, by nearly all accounts, have become overly obsessed with maxing out their protein as a way to feel full and hopefully lose weight. With all the emphasis on gut health and the clear connection to fiber, I think there’s certainly a chance some of it break through for everyday consumers looking for ways to stay health and maintain a healthy weight and microbiome.
That said, it’s likely Americans’ fixation won’t end soon. As Mike Lee said on a (separate) panel recently, “Protein is the Tom Cruise of the American diet.”
In other words, protein’s starring role won’t end anytime soon, but maybe there’s a chance fiber may someday get equal billing.
