This week's King of Food is about looking young and four guests bring along what they eat regularly. 60-year-old rocker Yu Hyeonsang reveals what he eats to satisfy his wife who's 13 years younger. Singer Ha Choonhwa debuted 53 years ago but doesn't look it at all. Comedian Kim Yeongcheol hasn't changed in many years, and there's anchor Park Eunyeong. The King of Food recommends sea squirts for people who want great skin.
