Gyeonggi Health and Environment Research Institute: 'Chwinamul' is the Colon that Suppresses Intracellular Inflammation-Inducing Reactive Oxygen Species

Gyeonggi-do Institute of Health and Environment

[Asia Economy (Suwon) = Reporter Lee Young-gyu] The Gyeonggi-do Institute of Health and Environment Research announced that chwinamul contains the highest amount of 'chlorogenic acid,' an antioxidant that suppresses the production and accumulation of reactive oxygen species that cause inflammation in the body.

The Gyeonggi Institute of Health and Environment Research announced on the 5th the results of a four-month investigation starting from August last year into the content of the antioxidant 'chlorogenic acid' in vegetables and tubers commonly consumed in the province.

Chlorogenic acid is a type of polyphenol that helps strengthen immunity and suppress aging and obesity by inhibiting the production and accumulation of reactive oxygen species that cause inflammation in the body through cellular dysfunction.

The survey covered 39 vegetable items including chwinamul, kale, lettuce, perilla leaves, spinach, and 4 tuber items including sweet potatoes, potatoes, yam, and taro.

The results showed that chlorogenic acid was present in 24 items in total, with chwinamul having the highest content among vegetables at 38.3 mg per 100g. This was followed by kale (22.9 mg), minari (10.7 mg), and burdock root (9.7 mg).

Among tubers, pumpkin sweet potatoes (1.4 mg) and red potatoes (0.4 mg) contained higher amounts than other tubers.

The Gyeonggi Institute of Health and Environment Research also presented research results on cooking methods to increase the chlorogenic acid content.

They explained that blanching chwinamul and minari for about 30 seconds and steaming potatoes and sweet potatoes in a colander resulted in higher chlorogenic acid content. Additionally, they noted that the skin contains the highest amount of chlorogenic acid by part.

A representative from the Gyeonggi Institute of Health and Environment Research said, "There has been a lack of research on antioxidants in vegetables and tubers commonly consumed by residents, which led to this study. We hope this research will help improve the health of the residents."
