How many times have you heard people say that eating junk food gives you spots? And how many times have you wondered whether or not this is true?
In the case of pizza, it might just be what you choose to put on top of it that can lead to breakouts. Cheese, like all dairy products, can cause breakouts in some people, because it has a high content of androgens (precursors to male hormones) and it also affects the insulin levels in your body. Both of these can increase the amount of oil that your skin produces, and when the glands in the skin make too much oil, this can clog the pores and cause breakouts.
As well as cheese, the pizza dough contains gluten, and some people can’t tolerate this. If you’re sensitive to gluten, the skin might break out in response.
