Are lectins toxic? | Alan Flanagan, PhD & Matthew Nagra, Nd

Listen Now

Legumes are trying to kill you. At least, that’s what Dr Steven Gundry would have you believe. Over the decades, various health fads have targeted one nutrient or compound after another: carbs, fat, gluten, and now, lectins. In Episode #286, I sit down with Dr Alan Flanagan, PhD, and Dr Matthew Nagra, ND, to dissect the bold assertions made in Dr Steven Gundry’s book, The Plant Paradox.

“When you take a step back and look at the actual human clinical trial data, we see that these plant foods tend to be quite beneficial, at least for inflammatory markers.” – Dr Matthew Nagra

In this episode, we are joined by two exceptional experts in the field of nutrition. Dr Alan Flanagan, PhD, is an accomplished nutritionist and the founder of Alinea Nutrition. He brings a rich background that spans both law and science, with a special focus on imparting impartial, science-based nutrition analysis.

We’re also joined by Dr Matthew Nagra, ND, a passionate advocate for plant-based nutrition and a certified expert from Cornell University. Growing up with personal health struggles and witnessing the transformative power of lifestyle-based interventions in his own life and his father’s, Dr Nagra merges his comprehensive medical training with a deep-rooted commitment to bridging the gap between lifestyle changes and medical treatments.

“Unfortunately the gaps [in scientific literature] are often manipulated by someone like a Steven Gundry to make a specific claim, and that can be incredibly persuasive to people.” Dr Alan Flanagan

More about Dr Matthew Nagra, ND

Dr Nagra grew up in Qualicum Beach on Vancouver Island, and from a young age, he struggled with multiple health issues such as asthma, allergies, and weight management. It wasn’t until he took control of his own health and began transitioning to a plant-based diet that he noticed significant improvements, which was ultimately the catalyst for the career he has chosen. His goal is to help others do the same.

He graduated from the Boucher Institute after having completed his Bachelor of Science in Microbiology at the University of Victoria 4 years earlier. He holds additional board certifications in prescriptive authority, immunizations, advanced injection therapies, intravenous therapies, and acupuncture. Using an evidence-based approach, he creates individualized treatment protocols for each patient based on their health goals and unique lifestyles.

Dr Nagra has a particular passion for plant-based/vegan nutrition, physical medicine, and chronic disease treatment. With additional training in nutrition, he holds a Plant-Based Nutrition Certification from Cornell University and the T. Colin Campbell Center for Nutrition Studies where he’s authored multiple articles on the subject. There’s certainly a lack of understanding around plant-based nutrition amongst healthcare professionals, sometimes resulting in practitioners recommending non-vegan treatment options to their vegan patients. His aim is to help that population thrive while maintaining their vegan lifestyle if that’s their goal. Beyond catering to the plant-based population, his passion for nutrition is only amplified by his personal health struggles and his father’s battle with cardiovascular disease, where both were able to regain their health after making significant lifestyle changes. Dr Nagra believes this is where he can have the greatest impact in helping patients transform their lives by bridging the gap between lifestyle-based interventions and life-saving medical treatment.
