Actor Son Jun-ho’s account of IU chewing a piece of kimbap for about 30 minutes has become a widely covered entertainment item after his appearance on SBS Love FM’s “Yoo Min-sang’s Hungry Radio.” The IU kimbap anecdote was tied to the set of MBC’s Friday-Saturday drama “21st Century Grand Prince’s Wife,” where Son said he and Kim So-hyun were appearing as special guests and shared a dressing room area with IU.1
Several Korean outlets reported the same central detail from the radio appearance and related SBS Radio “Erao” YouTube content: Son said he saw IU continue chewing a single piece of kimbap for an unusually long time during a meal break. Newsen reported that the YouTube video uploaded on May 11 repurposed visible-radio footage from the May 6 broadcast of “Yoo Min-sang’s Hungry Radio.”2
Son Jun-ho’s IU Kimbap 30-Minute Account

Son’s description centered on a filming-day meal rather than a new statement from IU herself. In the version carried by OSEN through Chosun Biz, Son said he saw IU chewing kimbap for more than 30 minutes during the filming of “21st Century Grand Prince’s Wife,” and that the kimbap on the table appeared to have barely decreased afterward.1
The direct remarks quoted across reports were brief but consistent. OSEN quoted Son as saying, “She put in one kimbap and chewed it for 30 minutes.”1 Newsen quoted a similar line: “She put in one piece of kimbap and kept chewing.”2 Sports Chosun also reported that Son said IU had put in one piece of kimbap and continued chewing it.3
The setting also matters for understanding the story’s limits. The reports frame the account as an anecdote from Son’s observation during a drama set appearance, not as a medical claim, diet instruction, or official explanation from IU’s side. Kim So-hyun and radio host Yoo Min-sang were described as reacting with surprise when Son explained the long chewing episode.2
Reports Link the Story to Earlier Slow-Eating Mentions
The coverage did not treat the kimbap anecdote as entirely isolated. Sports Chosun noted that IU had previously said in other content that she chews roughly 150 times when she eats.3 Money Today also connected the episode to earlier public attention around IU eating slowly on JTBC’s “Hyori’s Homestay” and reported that she had said on a broadcast that she tends to chew more than 100 times per bite.4
The Korea Economic Daily placed Son’s remarks in a health-themed article and said IU had previously spoken on the YouTube channel “Bdeonuseu” about chewing food a lot.5 Seoul Shinmun likewise reported the same set anecdote and connected it to IU’s past comments about chewing food thoroughly.6
These follow-up references explain why the short radio exchange traveled beyond a routine broadcast clip. The central point repeated in the reports was not merely that IU ate kimbap on a set, but that Son’s observation appeared to match a pattern already visible in earlier entertainment content: IU has been described, and has reportedly described herself, as someone who chews food slowly and many times.
Still, the available reports do not provide a response from IU to Son’s specific radio anecdote. They also do not establish the exact amount of food IU ate that day beyond Son’s description that the kimbap seemed largely unchanged after he noticed her long chewing. The story therefore rests on Son’s recollection and on how multiple outlets summarized the radio and YouTube material.
Health Framing Appears in Later Coverage
Some outlets expanded the entertainment anecdote into a general discussion of chewing habits. Money Today described possible digestive benefits of chewing slowly while also noting possible concerns such as insufficient nutrition or strain on the jaw joint if taken to an extreme.4 Seoul Shinmun also included general commentary related to chewing and digestion alongside the report on Son’s remarks.6
That health framing should be read as general context, not as a diagnosis or evaluation of IU. The reports did not state that IU has a health condition connected to the kimbap anecdote, nor did they present the 30-minute claim as medical evidence. The source-backed facts are narrower: Son described what he said he saw on a drama set, other broadcast material has previously shown or referenced IU eating slowly, and several outlets used the episode to discuss the broader habit of chewing food thoroughly.

The IU kimbap story remains a compact entertainment update built around one radio anecdote and its amplification through Korean media coverage. Based on the available reports, the confirmed focus is Son Jun-ho’s account from “Yoo Min-sang’s Hungry Radio,” the May 11 SBS Radio “Erao” YouTube-related coverage, and the repeated description that IU chewed one piece of kimbap for about 30 minutes during a “21st Century Grand Prince’s Wife” filming setting.
