|There are many misconceptions and rumors about what does and does not cause the condition:|
Diet. One flawed study purported that Chocolate, french fries, potato chips and sugar, among others, affect acne. A recent review of scientific literature cannot affirm either way. The consensus among health professionals is that acne sufferers should experiment with their diets, and refrain from consuming such fare if they find such food affects the severity of their acne. A recent study, based on a survey of 47,335 women, did find a positive epidemiological association between milk consumption and acne, particularly skimmed. The researchers hypothesize that the association may be caused by hormones (such as bovine IGF-I) present in cow milk; but this has not been definitively shown. Seafood, on the other hand, may contain relatively high levels of iodine, but probably not enough to cause an acne outbreak. Still, people who are prone to acne may want to avoid excessive consumption of foods high in iodine. It has also been suggested that there is a link between a diet high in refined sugars and acne. According to this hypothesis, the startling absence of acne in non-westernized societies could be explained by the low glycemic index of these tribes' diets. Further research is necessary to establish whether a reduced consumption of high-glycemic foods (such as soft drinks, sweets, white bread) can significantly alleviate acne, though consumption of high-glycemic foods should in any case be kept to a minimum, for general health reasons.
Sex. Common myths state that either celibacy or masturbation cause acne and, conversely, that sexual intercourse can cure it. There is no scientific evidence suggesting that any of these are factual. It is true, though, that anger and stress affect hormone levels and thus bodily oil production, which can cause acne.
