An increasing body of research indicates that dietary change may serve as a component of therapy for certain skin conditions. This include conditions such as acne, atopic dermatitis, ageing skin, psoriasis, and rosacea. Certain nutrients, foods or dietary patterns may act as disease "triggers" while others may prove beneficial. Avoidance or elimination diets may be helpful in some conditions although testing may be recommended first.
The strongest evidence to date on dietary triggers for acne is for high-glycemic-load (carbohydrates) diets. This dietary pattern results in lower androgen bioavailability and altered skin sebum production.
Low carbohydrate diets decrease skin inflammation and sebaceous gland size.
Foods or supplements containing probiotics, omega-3 fatty acids, zinc, antioxidants and fibre may be beneficial.
While it has long been recognized that diabetics experience poor wound healing, there is now a greater recognition that these effects on collagen can promote skin wrinkling. Higher levels of blood sugar can result in the production of advanced glycation end products (known as AGEs) via glycation and cross-linking of collagen fibers. This ultimately results in a loss of elasticity. Consumption of pre-formed AGEs, created during certain cooking processes such as deep-frying can also be detrimental.
