Abstract
Age-related cognitive decline (ARCD) and neurodegenerative diseases are increasingly prevalent due to longer life expectancies, with oxidative stress playing a central role in these processes. Functional foods, which are rich in omega-3 fatty acids, antioxidants, polyphenols, vitamins, and minerals, offer promising neuroprotective benefits. These bioactive compounds enhance neuronal signaling, reduce oxidative stress, and mitigate neuroinflammation. Epidemiological studies have shown a correlation between diets high in fruits, vegetables, fish, and nuts and a reduced risk of cognitive decline. Clinical trials also demonstrate improvements in memory, attention, and executive function from specific supplements. Omega-3 fatty acids from fish oils enhance synaptic plasticity and support the structural integrity of neuronal membranes. Antioxidants neutralize reactive oxygen species, preventing cellular damage. Polyphenols, found in berries and other plant-based foods, exert potent antioxidant and antiinflammatory effects and can influence brain function through the gut–brain axis. Thus functional foods emerge as a natural and accessible strategy for maintaining cognitive health and mitigating cognitive aging. Regular consumption of these foods, along with a balanced diet and healthy lifestyle, could provide significant benefits in preserving cognitive function and reducing the risk of neurodegenerative diseases.
