• Associations of Distinct Dietary Indices with Global and Domain-Specific Cognition and Age-Related Heterogeneity in Older Chinese Adults (2026) · Nutrients · doi

  Prospective studies with repeated assessments of diet, cognition, nutritional status, and functional health are needed to clarify the processes underlying these statistical interactions, - Future studies may therefore benefit from clearly distinguishing the dietary dimensions represented by different indices while evaluating the extent of information they share, - Trials and prospective cohorts could therefore incorporate sufficiently sensitive domain-specific outcomes alongside global cognitive measures, - The statistical interactions observed across later life support examining a broad age range, including the oldest old, in future prospective studies

• The consequences of ultra-processed foods on brain development during prenatal, adolescent and adult stages (2025) · Frontiers in Public Health · cited 35× · doi

  Ultra-processed foods jeopardise brain health across the life- course, as summarised in Figure 1. Evidence now links prenatal, childhood, adolescent and adult exposure to a continuum of neurocognitive harm that ranges from executive-function deficits and reward-circuit dysregulation to dementia. Key mechanistic threads include dopaminergic hypersensitisation, hippocampal vulnerability to metabolic inflammation, and disruption of the gut–brain axis. Because these risks accumulate across time and generations, the greatest benefit will come from interventions that start early and minimise cumulative dose. Policy levers that curb UPF availability, require unambiguous front-of-pack labelling, and stimulate reformulation are urgently needed. Longitudinal neuro-imaging with objective dietary metrics should be prioritised to confirm causality and pinpoint sensitive windows. Meanwhile, clinicians can act now by helping patients FIGURE 1 The lifelong and intergenerational impact of ultra-processed foods (UPFs) on health and neurodevelopment. This figure illustrates the profound and cumulative effects of UPF consumption across different life stages, prenatal period, childhood, adolescence, adulthood, and old age, highlighting their role in a broad spectrum of neurodevelopmental, metabolic, cardiovascular, and cognitive disorders.

• Dietary (Poly)phenol Intake, Inflammatory Biomarkers, and Mild Cognitive Impairment in Italian Adults (2026) · Antioxidants · doi

  There is a lack of evidence specifically addressing mild cognitive impairment and dietary (poly)phenol intake. Prior studies have had inconsistent findings regarding the association between dietary (poly)phenols and cognitive health. This study aims to address this gap by investigating the relationship between habitual dietary (poly)phenol intake and mild cognitive impairment in older adults.
