A study published in the journal Dermatology found a positive association between intake of milk and acne amongst teenage girls.
“For certain people, milk can aggravate skin conditions such as acne or pimples says Urbod Nutritionist Amanda Michie. Milk contains androgenic hormones and other bioactive compounds such as Insulin-like Growth Factor-1 (IGF-1) which promote secretion of sebum and stimulate the growth of certain skin cells implicated in acne. From a Nutritional perspective, the best way to tackle acne is to eat plenty of fresh vegetables, salads and some fruit; reduce sugars (as a sugar-laden diet stimulates IGF-1) and cut out hydrogenated fats. Saturated fats from dairy and other animal products should be eaten in moderation and replaced with oily fish and vegetarian sources of protein such as tofu, eggs, seeds and legumes such as beans, peas and pulses."
