Dietary Intervention on Atopy

Atopic dermatitis (AD) is a chronic inflammatory skin disease that frequently persists into adulthood and substantially impairs quality of life, sleep, and psychosocial well-- being. While pharmacological therapies remain central to management, in- complete responses and concerns regarding long-- term use have prompted interest in complementary, non-- pharmacological strategies. Dietary modification has emerged as a potentially modifiable adjunct; however, adult intervention trials remain limited and have predominantly focused on single-- nutrient supplementation or elimination-- based approaches rather than whole-- diet modification. Evidence from Asian adult populations is particularly scarce. Building on our prior epidemiological findings demonstrating that frequent intake of saturated fat (SFA)-- rich foods was as- sociated with higher odds of AD exacerbation, whereas greater consumption of fruits, vegetables and dietary fibre was associ- ated with lower odds, we aim to conduct a pilot, parallel-- arm, assessor--blinded randomised controlled trial (RCT). The RCT evaluated whether a culturally adapted healthy dietary pat- tern (HDP), aligned with Singapore's My Healthy Plate (MHP) guidelines, could reduce AD severity as measured by clinical symptoms.
