Pineapple, one of the most popular fruits consumed throughout the world, contains various nutrients and has been reported to have various health effects. Since most of research on the health effects of pineapple has been conducted on Westerners, the effects on Japanese with different intestinal flora and skin type from Westerners are not clear. To exploratively evaluate the health benefits of pineapple intake for the Japanese, a randomized, untreated-controlled, parallel-group clinical trial was conducted. Japanese women tending to get constipate were given 100 g of pineapple per day for 4 weeks, and the intestinal flora, defecation status, skin questionnaire, and blood components were measured before and after ingestion. As a result, effects on changing the intestinal flora, defecation status, and skin condition were observed in the pineapple intake group. These results may lead next study investigating the respective interaction between pineapple intake, intestinal condition and skin condition.
