Now, do you think acne is caused by eating chocolate, nuts, cola, pizza, potato chips or any other foods?  In a word, "no".  There are no predictable dietary causes of acne, though it is credible that some peoples acne worsens when they eat certain foods.  Does stress cause acne?  Indirectly, possibly; the mechanism is thought to be increased production of male-type hormones which in turn stimulate oil glands whose product, in turn is the fuel for acne's fire.
