Adult Acne Blog - thebroadroom.net: Okay, that is not entirely accurate...
Disclaimer: I am not a doctor, nurse, nutritionist, herbalist, or otherwise medically trained person.
I am an ordinary person who has suffered from adult acne since 1995 and have found no solution to my acne through conventional medicine.
Even if I take my multi-vitamin and Yasmin regularly--if I eat a lot of regular beef (as opposed to health food store type beef), I'll still start to get pimples again.
By now of course I buy the majority of the milk I drink from Safeway (which, weirdly enough, started carrying growth-hormone-free milk a long time ago...peruse this blog and you'll get an approximate date). That's the cheapest growth-hormone-less milk; it's also sold at Trader Joe's and under certain brand names such as Berkeley Farms.
Those are the three main factors. I don't eat a lot of fast food or drink a lot of soda (the former I probably went for once a week or every other week, before; the latter I used to drink constantly). A little harder to quantify those as factors but I think they are factors too.
