About this episode
The episode discusses the toxicity of MSG and excitotoxins, their impact on neurological health, and the role of nutrition in mitigating these effects.
Listen Online: About this episode: What begins as a conversation about MSG quickly expands into a much larger discussion. The First Lady of Nutrition welcomes back board-certified neurosurgeon Dr. Russell Blaylock to explore excitotoxins — compounds such as glutamate that overstimulate brain cells and often appear on labels under disguised names. He explains how these additives may influence addiction, neurological health, and why they are far more common in the U.S. food supply than in many European countries. The interview also covers neurodegenerative disease, the role of glutamate in cancer growth, and ways to calm excess glutamate activity. Ann Louise and Dr. Blaylock also discuss key nutrients, including high-dose benfotiamine and other B vitamins, and why many neurological conditions like Parkinson’s may be linked to thiamine deficiency. The conversation then broadens to immune function and COVID-related concerns, including neurological effects and post-illness immune changes, along with nutrients and flavonoids involved in regulating the p-53 gene. What starts with food additives ultimately becomes a wider look at how modern exposures may be shaping brain health…
