Researchers at the University of Missouri have unveiled findings suggesting that the ketogenic diet could play a significant role in reducing the risk of Alzheimer`s disease. Their study indicates this diet exerts its beneficial effects by simultaneously influencing both gut and brain health. Published in the Journal of Neurochemistry (JN), the research specifically highlighted that for individuals carrying the APOE4 gene — a major genetic predisposition for late-onset Alzheimer`s — this dietary regimen effectively restores the gut microbiome and enhances brain metabolism.
Laboratory experiments conducted on mice demonstrated compelling results. The ketogenic diet was observed to notably increase the population of beneficial bacteria, including Lactobacillus johnsonii and L. reuteri, while simultaneously decreasing the levels of potentially pathogenic microorganisms. These positive alterations in gut flora were directly linked to several crucial improvements within the brain: enhanced mitochondrial function, better balance of neurotransmitters, and optimized lipid metabolism. All these factors are universally recognized as critical components of robust cognitive health.
A particularly striking impact was noted in female mice possessing the APOE4 gene. In this specific group, the diet led to a remarkable restoration of microbiome diversity and a normalization of key metabolic indicators within the brain. Based on these observations, the study`s authors propose that the ketogenic diet could emerge as a powerful, personalized nutritional strategy. Such a strategy would be aimed at mitigating the risk of various neurodegenerative diseases, with a specific emphasis on women who carry a genetic susceptibility to Alzheimer`s.
This research builds upon previous scientific discoveries, which also indicated the diverse benefits of the ketogenic diet. Earlier studies, for instance, had shown that following a ketogenic diet could lead to a substantial reduction in depression symptoms — nearly 70 percent — within a mere 10-week period, underscoring its broad potential for neurological and mental well-being.
