Purpose of the Review <p>Age-related cognitive decline is an important global challenge. Substantial evidence suggests that diet may prevent or delay cognitive aging.</p> <p>This narrative review examines recent literature on how dietary factors influence cognitive function, with a focus on subjective cognitive decline (SCD).</p> Recent Findings <p>Higher intakes of flavonoids, carotenoids, and plant-based protein were associated with lower odds of SCD. Berries, citrus fruits and juices, carotenoid-rich and green leafy vegetables, and beans/legumes were among the foods with the strongest inverse associations with SCD. Healthy dietary patterns, such as the Mediterranean and MIND diet, may be beneficial for maintaining subjective cognitive function.</p> Summary <p>Healthy choice of diet may play a role in lowering the risk of late-life SCD.</p>
