In recent years, improvement of skin condition through dietary modification has attracted attention. Pineapple, a popular fresh fruit, is rich in various nutrients including glucosylceramide, which are expected to improve the functions of skin such as protection. In this study, in order to clarify the health effects of pineapple, a randomized controlled trial was conducted in healthy adult men and women with skin problems and tendency for constipation. Twenty-four subjects allocated to the pineapple intake group ingested 100 g of pineapple daily for 8 weeks, while 24 subjects were allocated to the non-intake group (control, no intake of pineapple). As a result, parameters of dryness, wrinkles, and skin color of the pineapple intake group were significantly improved both subjectively and objectively. In addition, significant improvements in defecation status and intestinal flora were observed. These results suggest that long-term intake of pineapple may improve skin health and the intestinal environment.
