Air Pollution, Oxidative Stress, and Nutritional Protection
Air pollution is a top-5 global health risk. While environmental mitigation is primary, nutritional strategies can blunt some of the inflammatory and oxidative damage from particulate and ozone exposure.

Chronic Allergic Inflammation in Aging: Mechanisms and Evidence-Based Management
Allergic inflammation can worsen with immune senescence, contributing to systemic inflammatory load. This article covers the evidence for dietary and supplement interventions that modulate allergic response without the side effects of antihistamines.

Circadian Rhythm Disruption in Aging: Mechanisms, Health Consequences, and Restoration
Circadian clocks govern virtually every physiological process — metabolism, immune function, DNA repair, and hormone secretion follow 24-hour rhythms entrained by light. With aging, the circadian system weakens: clock gene amplitude declines, light sensitivity decreases, and circadian outputs desynchronize. Strengthening circadian inputs through light exposure, meal timing, and physical activity has evidence-based effects on sleep, metabolic health, and biological aging.

Age-Related Hearing Loss: Mechanisms, Cognitive Links, and Nutritional Support
Age-related hearing loss (presbycusis) affects over 60% of adults over 70 and independently accelerates cognitive decline. This article reviews the mechanisms and the limited but growing evidence base for nutritional support.
