In one study, Korean researchers found that when adults followed a typical low-glycemic Korean diet for 10 weeks, acne severity dropped by 27 percent, sebaceous gland size dropped by 25 percent and overall inflammation dropped by 40 to 50 percent. With numbers like that, consider us swayed in the argument for the skin-diet connection.

The Pungent, Probiotic Powerhouse
Skin perks: This skunky superfood contains lactobacillus, the same good-for-you bacteria found in yogurt, which promotes a healthy balance of bacteria in the gut. Many doctors link the health of your gut to the health of your skin. Since inflammation in the gut is tied to skin issues like acne, kimchi may be the zit-zapper you've been craving.
Besides reducing acne, kimchi may prevent wrinkles by adding moisture to your skin. A study published in January 2015 found that subjects who ate the bacteria found in kimchi on a daily basis experienced improved skin barrier function and an increase in hyaluronic acid — a moisturizing ingredient you pay big bucks for in skincare products — after just four weeks.
How to eat it: Many health food stores carry jars for around seven dollars. Koreans eat it as a side dish or over rice for a simple meal.

The Korean Alcoholic Beverage That's Actually Good for Your Skin
Skin perks: One bottle of makgeolli contains as many probiotic cultures as 100 cups of yogurt, making it a treat for your digestive system and skin. Some Koreans even apply it directly to the skin — popular Korean beauty brand Tony Moly sells a makgeolli sheet mask. It's also full of amino acids and vitamin B, which firm and brighten skin.
How to eat it: To get the beauty benefits, you need to drink fresh makgeolli that's been brewing for about a week (the longer it ferments, the less potent it becomes). A quick Yelp search for makgeolli in your area can point you in the right direction.

The Soup That Protects Against Skin Cancer
Skin perks: "In Korea, seaweed soup is the first thing a woman eats after giving birth," says Lee. It's also tradition to eat it on your birthday, because your mom ate it after giving birth to you, she adds. The mineral-rich sea dish is chock-full of skin-saving nutrients -- just one sheet of nori (the seaweed used to wrap sushi) has the same amount of omega-3s as two whole avocados. Omega-3s help your skin maintain a natural oil barrier, and research shows a daily dose protects the skin from sun damage.
How to eat it: Try this simple seaweed soup recipe. Visit the Asian section of your grocery store for ingredients.

The Smile-Protecting, Skin-Repairing Tea
Skin perks: Barley tea contains a large number of antioxidants. One study found that these antioxidants were effective in preventing the formation of peroxynitrite, an oxidant that attacks skin tissue and creates DNA damage — a major culprit of wrinkles. Bonus: Another study found that barley tea prevents tooth decay by preventing bacterial colonization — think of it as a hot, bacteria-killing mouthwash that is A-OK to swallow.
How to eat it: Koreans generally have barley tea available for every meal — it's often already on the table at restaurants. Depending on the time of year, it's served hot or cold.
