Research indicates that acne vulgaris, an epidemic inflammatory skin disease typically occurring during adolescence, is closely associated with Western diet. Three major food categories that exacerbate acne include:
- High-glycemic carbohydrates
- Milk and dairy products of certain types and quality
- Polyunsaturated fatty acids from vegetable oils
- Trans fats in combination with insufficient intake of omega-3 fatty acids.
Deviation in sebum quantity (hyperseborrhea) and composition (dysseborrhea) promotes the overgrowth of the bacterium Propionibacterium acnes and biofilm formation, increasing the risk of acne. Diet plays a significant role in these deviations. A paleo-like diet enriched with vegetables [note: not all types] and fish supports nutritional therapy for acne vulgaris. The diet recommended in the Acne Clear program has been proven effective over many years in permanently eliminating acne and pimples.
