K-Celeb Jeon Hye Bin Roasts Yam for Potential Blood Sugar Control and Gut Microbiome Benefits

Yam is a root vegetable that contains starch, dietary fiber and polysaccharides, along with distinctive sticky mucilage and various bioactive compounds. Research is continuing into its potential links to gut health and post-meal blood sugar control.Actress Jeon Hye Bin, 43 years old, recently purchased yam while shopping at Gyeongdong Market on her YouTube channel. Jeon Hye Bin put 1 kg of yam in her shopping basket, saying, “Yam is delicious when roasted, too.” Here is a look at how it may help.When yam is cut, its sticky mucilage can be seen. Yam contains starch, mucilaginous polysaccharides, phenolic compounds, saponin-related compounds and protein. Dioscorin, in particular, is yam’s major storage protein and accounts for the largest proportion of its water-soluble proteins. It is being studied as a functional food ingredient after antioxidant and immune-regulating effects were reported.Meanwhile, a study published in the international journal ‘Food Chemistry’ summarized reports of the potential of yam polysaccharides to help regulate blood sugar, protect the gut and regulate the gut microbiota.In a study of 92 patients with type 2 diabetes who had undergone colorectal cancer surgery, some received standard treatment alone while others consumed 150 g of yam porridge daily for three weeks alongside their treatment. In the group that ate yam porridge, some beneficial gut bacteria increased, while indicators of intestinal barrier damage and fasting and post-meal blood sugar levels also improved.Although yam contains various bioactive compounds, it is also a starchy vegetable. Eating a large amount at once because it is considered good for health can also increase carbohydrate and calorie intake. It is especially important for people who need to manage their blood sugar to control how much they consume.Yam can be grated or thinly sliced and eaten raw, or it can be roasted or steamed, as Jeon Hye Bin did.There are also points to keep in mind when grating yam and drinking it like a beverage. Adding large amounts of honey, sugar or syrup can easily increase sugar intake, so those seeking health benefits should eat an appropriate amount while preserving the yam’s own flavor.
Some people may also experience itching or stinging when cutting or peeling raw yam. Yam contains calcium oxalate crystals and other substances, and these crystals can cause physical irritation when they come into contact with the skin.If you have sensitive skin or have experienced itching before, it is advisable to wear gloves and avoid handling yam with bare hands for an extended period. After preparing it, wash your hands and cooking utensils thoroughly under running water.
