New research suggests that the gut microbiome may play a role in social anxiety disorder, with transplant experiments in rats showing that bacteria from adolescents with social anxiety induce anxiety-like behaviors and brain changes, highlighting a potential biological link via the gut-brain axis.
A high-fat diet disrupts the gut-brain axis by increasing serotonin in the gut while depleting it in the brain, leading to inflammation, impaired mood, and metabolic issues, highlighting the importance of gut microbiome health for mental and physical well-being.
A comprehensive review suggests that most people who believe they are gluten sensitive are actually reacting to other factors like FODMAPs or psychological influences, with true gluten sensitivity being rare. The study emphasizes the importance of proper diagnosis and personalized treatment, highlighting that unnecessary gluten avoidance can be costly and nutritionally detrimental.
A comprehensive review suggests that most people who believe they are gluten sensitive are actually reacting to other dietary components like FODMAPs or psychological factors, rather than gluten itself. True gluten sensitivity appears to be rare, and symptoms are often influenced by expectations and anxiety. The study recommends targeted testing and dietary adjustments, emphasizing the importance of personalized, evidence-based approaches over unnecessary gluten avoidance.
A comprehensive review in The Lancet challenges the common belief that gluten is the primary cause of symptoms in people without coeliac disease, suggesting that many such cases are due to other dietary factors like FODMAPs or psychological factors, and recommends targeted testing and dietary management instead of unnecessary gluten avoidance.
A study suggests that bacterial cell wall molecules like peptidoglycan are present in the brain and fluctuate with sleep cycles, supporting a new 'holobiont condition' model where sleep is regulated by interactions between the brain and microbiome, potentially influencing cognition, behavior, and evolution.
Researchers used the advanced AI model AlphaFold3 to predict the structures of all 25 human bitter taste receptors, finding it more accurate than previous models. The study revealed conserved intracellular regions and variable extracellular regions, suggesting these receptors play a dual role in taste and gut-brain signaling, with implications for appetite control, glucose metabolism, and diabetes research.
A large-scale study suggests that chronic gut problems, hormonal, metabolic, and nutritional issues like vitamin D deficiency may predict the risk of developing Alzheimer's and Parkinson's disease years before symptoms appear, highlighting the importance of early health markers and systemic health in disease prevention.
A global study has found a significant increase in gut-brain disorders like IBS and functional dyspepsia since the COVID-19 pandemic, especially among long COVID sufferers who also experience higher anxiety and depression, highlighting the need for updated research and care models.
Scientists have discovered a 'sixth sense' in humans where gut bacteria communicate with the brain via neuropod cells and the vagus nerve, using bacterial flagellin to influence appetite and behavior in real time, revealing a rapid neural pathway that helps regulate food intake based on microbial activity.
Researchers at Duke University have discovered a potential new 'sense' in the gut involving nerve cells called neuropods that detect bacterial signals, specifically flagellin, and communicate with the brain via the vagus nerve to regulate hunger, suggesting a complex gut-brain-microbiome connection that could have significant health implications.
Scientists are exploring how fungi living inside our bodies may influence our brain health, behavior, and diseases like Alzheimer's, with recent studies suggesting fungi could play a role in neurological conditions and mental health, although much remains to be understood.
A large-scale study using a novel computational method identified specific gut bacteria associated with autism spectrum disorder, highlighting the gut-brain connection and opening new avenues for research and potential therapies.
A study in mice shows that a high-fat diet can lead to obesity and anxiety-like behaviors, with changes in brain signaling and gut bacteria, suggesting a gut-brain connection in obesity-related mental health issues.
Eric Topol's book 'Super Agers' emphasizes that a strong immune system, personalized medical testing, nourishing the gut-brain axis, optimal sleep, and cautious use of AI are key strategies for aging healthily and feeling youthful into old age.
