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.
An estimated 40 million to 50 million Americans are affected by some form of
acne, and not just teenagers. Although up to 80% of people aged 11 to 30 say
they've been affected, it turns out that many of us, particularly women, have
acne in our late 30s and even into our 50s, says Jenny J. Kim, MD, PhD,
associate professor of dermatology at the University of California, Los
Angeles, David Geffen School of Medicine.
"Sometimes it is hard for patients dealing with acne to understand why, even
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.
