By now, it’s common knowledge that certain nutrients help specific body parts work better. Healthy bones require calcium and vitamin D. Our hearts may do better when we eat fish rich in omega-3 fatty acids. And for healthy skin we should eat, well, hmmm, that’s a good question.
If you’re not sure which foods are good for your skin and which ones are harmful, you’re certainly not alone. Little research has shown a connection between particular foods and skin health, says Cheryl Karcher, MD, a New York dermatologist who worked as a nutritionist before she became a doctor. And a lot of the “common knowledge” that people pass around about eating and skin health is based on individual people’s cases, she says.
Lindsey Emery, a freelance editor in Portland, Ore., asked about her bumpy skin. We passed her question on to Julie Harper, MD, a clinical associate professor of dermatology at University of Alabama at Birmingham, and Paul M. Friedman, MD, a clinical assistant professor of dermatology at the University of Texas, Houston, and author of Beautiful Skin Revealed: The Ultimate Guide to Better Skin.
Q: I've noticed small red bumps on my face, jawline, and neck. Could it be rosacea? Or is it acne?
Still, “the skin is a reflection of your total body health,” says Karcher, who is a spokeswoman for the American Academy of Dermatology. A nutritious diet that keeps your inside healthy will help keep your outward appearance looking good. On the other hand, a poor diet will show up on your skin.
Several experts whose expertise straddles both nutrition and dermatology are here to tell you which foods may support smooth, healthy skin, and which foods are more likely to lead to rashes, blemishes, and breakouts.
The Blood Sugar Connection
For the first part of her career, Valori Treloar, MD, worked with patients like a typical skin doctor. But over time, she grew tired of the few options that she could use on hard-to-treat cases, as well as the serious side effects that some could cause.
So the Massachusetts doctor became a certified nutrition specialist and now promotes diet fixes to her patients along with medicine.
Several studies from 40 years ago “proved” that diet doesn’t cause acne, Treloar says, and this thinking became a widely held belief in medicine. “All through medical school and through my dermatology training, I was taught, ‘Don’t worry about what your patient eats, it’s not relevant to their acne,’” Treloar tells WebMD.
But in recent years, some research has supported new thinking.
