Khaberni - The Journal of Neurochemistry reported that a study conducted by scientists from the University of Missouri revealed the benefits of a famous diet in enhancing brain health and preventing dementia.
The study revealed that following the keto diet may reduce the risk of Alzheimer's disease, through its combined effects on the gut and brain.
Experiments on lab mice showed that the diet increased the number of beneficial bacteria such as Lactobacillus johnsonii and L. reuteri, while levels of opportunistic pathogenic microorganisms decreased. These changes were associated with improved mitochondrial functions, neurotransmitter balance, and brain lipid metabolism, which are important factors for cognitive health.
The effect was particularly notable in female mice carrying the APOE4 gene, where the diet helped restore microbial diversity in the gut and returned brain metabolism markers to normal levels.
Researchers believe that the keto diet may represent a personalized dietary strategy to reduce the risk of neurodegenerative diseases, especially among women genetically predisposed to Alzheimer's disease.
Despite its benefits, some studies have warned of potential risks, as an experiment at the Texas Health University indicated that the diet may increase cellular aging and oxidative stress in male mice.
