Your Brain On

Gluten has become one of the most misunderstood aspects of modern nutrition. Let’s set the record straight. In this episode, we untangle the medical, neurological, and cultural narratives surrounding gluten, from celiac disease and non-celiac gluten sensitivity to real (and rare) cases of gluten-induced brain dysfunction. We discuss: • The differences between celiac disease, gluten sensitivity, and wheat allergy • How gluten affects the gut, and what ‘leaky gut’ really means • Whether gluten can trigger neurological symptoms like ataxia and brain fog • Why cutting out gluten without a diagnosis may do more harm than good • How wheat contributes to a healthy microbiome (and why fiber matters) • What role zonulin plays in gut permeability and immune activation • Why brain fog isn’t yet well understood (and the theories behind it) To help us decode the science (and bust the myths) of gluten, nutrition, and the brain, we’re joined by two world-renowned experts: DR. ALESSIO FASANO: pediatric gastroenterologist, research scientist, and chief of Pediatric Gastroenterology and Nutrition at Mass General for Children (MGfC), and director of the Center for Celiac Research. DR. FRANK CUSIMANO: gastroenterologist, physician-scientist, and gut-brain health communicator with a PhD in Nutritional and Metabolic Biology from Columbia University Institute of Human Nutrition. This is... Your Brain On Gluten. ‘Your Brain On’ is hosted by neurologists, scientists and public health advocates Ayesha and Dean Sherzai. ‘Your Brain On...

Two-thirds of those diagnosed with Alzheimer’s disease are women — but why? In this episode, we unpack the neurological, hormonal, and social drivers that uniquely affect women's brain health during the menopausal transition — from estrogen’s protective role in the brain to the misunderstood history of hormone replacement therapy. We discuss: • Why women face a higher risk of Alzheimer’s than men • How menopause accelerates brain aging (and how it starts earlier than is often expected) • The role of estrogen in brain metabolism and neuroprotection • The real story behind hormone replacement therapy (HRT) • The impact of genes like APOE4 on women’s brain health • How lifestyle factors like stress, sleep, and cognitive activity can help reduce the impact of neurological changes onset by menopause ——— Get our free curation of women’s brain health resources in our Brain Box: http://thebraindocs.com/brainbox ——— To help us tell this story, we welcome three world-renowned women’s health experts to the podcast: DR.

Supplements have become a hundred-billion dollar industry. But can they really boost your brain health in the ways they claim? They’re everywhere: shelves and shelves of pills and powders promising everything from  improved immunity, boosted energy, and faster weight loss to better sleep, happier moods, and enhanced sexual wellness. Social media influencers won’t stop talking about them, and they seem to appear in TV commercials every five minutes. And yet... the evidence supporting most of the claims these supplements make is next-to-nought. So what’s the truth? In ‘Your Brain On... Supplements’, we discuss: The differences between supplements and medication Why supplements are so loosely regulated The most popular supplements, and the lack of evidence supporting their purported benefits Identifying between the placebo effect and real effects Some supplements with actual evidence-based potential The psychology behind why we all feel compelled to try supplements Tips for navigating supplement claims we see on social media Joining us for this episode is Dr. Adrian Chavez a nutrition researcher, educator, and consultant. He has a PhD in Nutrition and Health Promotion where he conducted research developing and delivering lifestyle interventions in community settings for improving cardiovascular and metabolic health.

Omega-3 supplements have become a multi-billion-dollar industry, promising to enhance your memory, boost your mood, and protect your brain. But where does the science end, and the marketing hype begin? Omega-3 fatty acids are a special category of ‘good fats’ that play vital roles in both brain and body health. Unlike some species, we can’t produce our own Omega-3s, so we must rely on our diets to get these essential fats. In this episode, we discuss how to get more brain-healthy quantities of Omega-3 into your diet, plus: • The brain health benefits of Omega-3 • The differences between Omega-3 and Omega-6 • The neurochemical intricacies of ALA, EPA, and DHA • Why Omega-3s are essential for development at a young age • The current (and future) state of Omega-3 research • Who needs Omega-3 supplements, and why Enriching the discussion this week are two celebrated experts in the field: DR.

High in fats and low in carbs, ketogenic diets were originally developed in the 1920s to treat children with epilepsy. Now, they’ve gained popularity for weight loss, and even improved cognitive function. But how much truth is there in the purported brain health benefits we see on social media? In this episode of ‘Your Brain On...’, we separate the facts from the fads, and discuss: • What one might eat on a typical ketogenic diet • How ketogenic diets affect brain metabolism • The different ways your brain uses sources of energy — glucose vs. ketones • The latest data on ketogenic diet in Alzheimer’s disease patients • What we know about how ketogenic diets and treatment of Alzheimer’s • The outcome differences between ketogenic diets and ketone supplements in Alzheimer’s • Other evidence-based nutritional approaches for brain health  For this episode, we welcome two world-renowned professionals in the field of nutrition and neuroscience: DR.

ALS, a nervous system disease, ruled the headlines in the summer of 2014 thanks to the viral Ice Bucket Challenge. How has our knowledge of the disorder evolved a decade later? Amyotrophic lateral sclerosis, also known as ‘Lou Gehrig's disease’ (named after the iconic baseball player), is a progressive neurological disorder which breaks down a person’s motor neurons. The main symptoms are muscle weakness and impaired physical function — mild, at first, but in the latter stages of the disease’s progression, essential processes like breathing begin to fail. Most individuals face a life expectancy of two to five years. A small percentage live five to ten years. And an even tinier group survive beyond a decade. Most famously, renowned physicist Stephen Hawking survived more than 50 years past his diagnosis, in part due to the intensive care he was able to afford. In this episode of the ‘Your Brain On...’ podcast, we discuss: • What ALS is, and how it affects the brain and the body • The onset and progression of ALS, from the earliest symptoms to the end-stage impacts • How ALS patients are diagnosed, treated, and cared for • Likely causes of ALS, including genetic predispositions and potential environmental risk factors • How new technologies are rapidly accelerating our understanding of ALS, especially in genetics Joining us for this installment of the show are two world-class experts on the disease: • Professor Ammar Al-Chalabi PhD, Professor of Neurology and Complex Disease Genetics at the Maurice Wohl Clinical Neuroscience Institute at King's College. • Merit Cudkowicz, Director of the Sean M.
