The 43-year-old posted the recipe on Instagram on Tuesday, according to Health Chosun. It involves mixing oats with Greek yogurt, fresh milk or soy milk, then adding chia seeds and frozen blueberries before refrigerating the mixture for about two hours.

Oats are widely regarded as a nutrient-rich food, once listed by The New York Times among the world’s 10 healthiest foods. They provide protein, essential amino acids, and minerals such as calcium, potassium, iron, and magnesium, while their high fiber content helps promote a lasting feeling of fullness.

Jin noted that chia seeds may help regulate blood sugar levels, as their fiber slows sugar absorption into the bloodstream. According to data from the U.S. Department of Agriculture, 100 grams of chia seeds contain around 34 grams of fiber.

Blueberries add antioxidants such as anthocyanins, polyphenols, and beta-carotene, which help protect the body from chronic conditions linked to free radicals, including cardiovascular disease, diabetes, obesity, and lipid disorders.

However, experts caution against overconsumption. Fiber in oats is fermented in the large intestine rather than digested in the stomach, which can lead to gas and bloating. A study published in the World Journal of Gastroenterology found that excessive fiber intake may contribute to bowel dysfunction, recommending no more than one or two servings per day.

Born in 1983, Jin began her acting career in 2007 with Temptation of Eve: Good Wife and initially took on supporting roles. She later gained recognition through Romantic Island and the film Believerwhich earned her multiple awards. Now married with one child, her post-pregnancy weight loss has attracted significant attention in South Korea’s beauty community.
