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.

Heat Stress and Aging: Why Older Adults Are More Vulnerable and How to Adapt
Thermoregulatory capacity declines with aging: sweating onset is delayed, cardiovascular reserve is reduced, and thirst is blunted. This article covers why older adults face higher heat mortality risk and what evidence supports safe heat adaptation.

Joint Health and Cartilage Support: What the Evidence Shows
Cartilage has limited self-repair capacity, but several interventions modestly slow degradation and reduce symptoms. Here is what the clinical evidence supports for joint health in aging.

Kidney Health and Aging: GFR Decline, Protein Intake, and Renoprotective Strategies
GFR declines ~1 mL/min/year after age 40. In early-stage CKD, protein restriction, blood pressure control, and avoiding nephrotoxic supplements (high-dose oxalate, aristolochic acid) are the primary levers. Potassium citrate and omega-3 have supportive evidence.

Skin Aging and Photoaging: Mechanisms, UV Damage, and Evidence-Based Interventions
Skin aging involves intrinsic (chronological) and extrinsic (UV-driven photoaging) components. UV radiation is responsible for approximately 80% of visible facial aging. Topical retinoids have the strongest evidence base for reversing photoaging signs. Oral collagen peptides have emerging RCT evidence for skin hydration and elasticity. Sun protection remains the highest-impact preventive intervention.
