A low-glycemic-load diet improves symptoms in acne vulgaris patients: A randomized controlled trial

Abstract

Background: Although the pathogenesis of acne is currently unknown, recent epidemiologic studies of non-Westernized populations suggest that dietary factors, including the glycemic load, may be involved. Objective: The objective was to determine whether a low-glycemic-load diet improves acne lesion counts in young males. Design: Forty-three male acne patients aged 15-25 y were recruited for a 12-wk, parallel design, dietary intervention incorporating investigator-blinded dermatology assessments. The experimental treatment was a low-glycemic-load diet composed of 25% energy from protein and 45% from low-glycemic-index carbohydrates. In contrast, the control situation emphasized carbohydrate-d..
