 This paper examines the effects of two different nutritional strategies, calorie restriction, CR, and intermittent fasting, if on brain health. The authors conducted an extensive literature review to identify relevant studies and found that both CR and if have been shown to improve brain health by reducing the risk of neurodegenerative diseases like Alzheimer's and Parkinson's. Additionally, they identified several potential mechanisms through which these strategies might work, including improved mitochondrial function, reduced inflammation, and increased production of neurotrophic factors. Finally, the authors concluded that further randomized studies should be conducted to better understand how these strategies can be used to prevent dementia in the elderly.
