There are significant data supporting the role of diet in acne. Our Western diet includes many dairy sources containing hormones.. ⋯ The presence of 5α-pregnanedione, 5α-androstanedione, and other precursors of 5α-dihydrotestosterone add to the potency of milk as a stimulant of acne. In addition, foods with significant sugar content and other carbohydrates yielding high glycemic loads affect serum insulin and insulin-like growth factor-1 levels, both of which promote increased production of available androgens and the subsequent development of acne.
