This review examined how bioactive compounds and physical exercise might converge to support brain function. The focus was on aging and neurodegenerative disorders like Alzheimer's and Parkinson's disease. Researchers looked at mechanisms such as hippocampal neurogenesis, synaptic plasticity, and cognitive resilience. They also considered secondary outcomes like memory retention, learning processes, and the mitigation of metabolic dysfunction or chronic inflammation.
The available evidence comes predominantly from preclinical studies, alongside emerging but comparatively limited clinical findings. The review synthesizes mechanistic evidence to evaluate how these interventions interact to influence brain plasticity and cognitive function. Existing literature largely examines exercise, nutrition, or metabolic regulation in isolation, which limits the ability to confirm combined effects in humans.
Readers should understand that this is not a practice-changing study yet. While the findings suggest potential benefits for the neuro-nutritional-metabolic axis, the clinical data is not yet robust enough to recommend specific regimens. The main reason to be careful is that current human data is sparse. Future research is needed to confirm these links and formulate tailored, multimodal interventions that specifically address these complex biological pathways.
