> Changing my diet helped clean up my acne (not eating junk food)

This. Actually, for me, it wasn't really the diet in general, but making a switch to drinking water instead of pretty much any other drink (*especially soft drinks!). I went on a hike for a couple of weeks as a teenager, and I think that not having access to anything but water to drink was enough to change my habits.

For me chocolate causes acne (usually on my back). It happens to my father too. When I eliminate that one item from my diet I am fine. Every few years I eat chocolate in hopes that my body's reaction will change. But 30 years later it still causes a reaction.

My high school health teacher insisted that chocolate does not cause acne, according to the research. Her definitive statement made me ignore what my father had been telling me for years. That's the problem with health science, you never know if you are an outlier to which the research does not apply.

It happens quite often, I donno why there is no supportive research on it.

My mother breaks out in acne when she eats chocolate. It's incredibly predictable and she ascribes it to being "allergic".
