My name is Maria Del Russo, and I hold these truths to be self-evident: A cheese plate is a perfectly respectable meal. A pack of shredded cheese is a great snack. Nachos deserve their own food group. If you're picking up what I'm putting down, then you're likely wondering why the hell I'd give up dairy for a month. Well, because good skin might just be more important to me than cheese. Might.The theory that dairy affects your skin is one that's been hotly debated among nutritionists, dermatologists, and pseudo-scientists on the internet. "The issue is more complex than saying it's good or bad," says Walter Faulstroh, the cofounder of Hum Nutrition . "There are a lot of different things that can be 'bad' about dairy. Is it the dairy itself, or is it the hormones? Or the way it was processed? That's why it's so heavily debated." Indeed, multiple studies have found that it's not always the dairy causing the breakouts, but how what is in dairy interacts with our unique chemistries.However, some dermatologists — like Jeannette Graf, MD — claim that there is an apparent link between dairy and acne. "When a patient of mine comes to me with a problem with acne, I put them on medication and I try to take them off dairy," she says. "I've noticed that when they don't stop with the dairy, the medication doesn't work as well."Thankfully, I no longer suffer from severe acne. After a short stint on doxycycline, and a serious restructuring of my skin-care routine, I've gotten to the point at which I only break out on my chin, with a few stragglers on my cheeks. Everyone from makeup artists to Facebook commenters to dermatologists says that I would likely see an improvement in those areas if I ditch dairy.It pained me deeply, but on July 31, I went through my cabinets and fridge and cleared out every last dairy product. Goodbye, Parmesan. See ya later, cow's milk. Of all the challenges I've tried, I knew this would be the hardest. Hell, even on the Perricone Diet , I was allowed a sprinkling of feta.I'd done my research into dairy-free alternatives ahead of this challenge, even going so far as to create a Pinterest board with all of my recipes. (It's not my sexiest board, I'll admit.) I looked into cheese-free ways to make some of my favourite things — like pesto and quesadillas. I went to Whole Foods and stocked up on Daiya cheese and nutritional yeast — both of which tasted like shit. I know that there are some major nutritional-yeast fans out there, but I'm here to tell you that stuff tastes and smells like a goddamn foot.After two days, I started craving cheese less. I didn't feel as bloated, and my stomach hardly ever bothered me. I also stopped getting that uncomfortable "full" feeling after meals. And even though I was just a few days away from getting my period, my skin didn't look all that terrible. In fact, it looked kind of glowy.
