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.

To prevent hypertension, which can cause various diseases, it is important to improve lifestyle habits such as eating habits. Bananas are rich in GABA, which has been reported to have hypotensive and stress-relieving effects. To evaluate the effects of long-term banana intake on blood pressure, defecation, and mental state, a randomized, parallel-group clinical trial was conducted. 78 Japanese with high blood pressure took either of the two bananas with different GABA contents for 4 weeks or did not take bananas. As a result, systolic blood pressure was significantly lower in both banana intake groups after ingestion compared with before ingestion. In addition, the number of bowel movements, the number of days of bowel movements, and the amount of bowel movements significantly increased. Significant improvements in the subjective questionnaires "fatigue" and "tension" were also observed. These results suggest that banana intake may have the effect of lowering blood pressure, promoting defecation, and improving mental state.

Pineapple, one of the most popular tropical fruits consumed throughout the world, is rich in dietary fiber, which is generally known to improve constipation. In Japan, one out of three elementary school children are reported to suffer from constipation, sometimes resulting in school refusal. To elucidate the health benefits of pineapple intake for Japanese children, a randomized, untreated-controlled, parallel-group clinical trial was conducted. Elementary school children tending to have constipation were given 100 g of pineapples per day for 4 weeks. The questionnaire for physical condition and defecation status, measurement of indoxyl sulfate in urine and analysis of intestinal microbiota were performed before and after the pineapple intake. As a result, defecation status was significantly improved and the proportion of beneficial gut bacteria was significantly increased in the pineapple intake group, indicating that pineapple intake could be helpful in improvement of defecation status and intestinal environment for elementary school children.
