The Food-Brain Connection: Doctor Explains Brain Inflammation

I'm hosting a live PMDD Relief Workshop on June 10th, free when you pre-order ADHD and Women. Get your spot at https://drbrighten.com/pmdd Brain inflammation and food are deeply connected and in this episode of The Dr. Brighten Show, Dr. Jolene Brighten sits down with Dr. Austin Perlmutter to explain how what you eat may influence brain fog, mood, cognition, inflammation, and the gut-brain connection. Dr. Austin Perlmutter is a board-certified internal medicine physician, New York Times bestselling author, and a leading voice in brain and body health. His work explores the biological roots of mental and physical “stuckness,” including how environmental factors, food, the microbiome, and immune signaling shape cognitive and emotional well-being. His work has reached millions through media outlets including PBS, Rolling Stone, and NPR. As Managing Director of Big Bold Health, Dr. Perlmutter is also leading food-as-medicine innovation, including research on how plant nutrients may influence human aging through epigenetic pathways. In this conversation, Dr. Perlmutter explains why your brain is literally built from the food you eat, how added sugar and sugar-sweetened beverages may contribute to systemic inflammation, why omega-3 fats like DHA and EPA matter for the brain, and how nutrients like B vitamins, amino acids, polyphenols, spices, coffee, and fiber can support brain and immune health.
