Health benefits of eating pineapples

These days we eat more pineapples than other fruits. The reasons : pineapples are easily available, sweet, healthier and juicier than most fruits here. In Singapore, we import most of the fruits from other countries. The exporters would pluck the fruits long before the fruits are ripened. They, then export the unripened fruits and over time, the fruits would "ripened" in an unnatural way. Take for example the papayas or oranges. These fruits are being exported unripened and after a few weeks of being plucked from the trees, they "ripened". This process of "ripening" is not good for consumption. I am not sure whether eating the fruits would be healthy.
However, for pineapples, the ripening process would take only a few days after exporting and so it is not unhealthy to consume them. Of course, taking them off the plants when they are ripened would be better.
The Malaysian Sarawak pineapples is the best of the lot. They are sweeter and juicier than their counterparts from other countries. The one (above) I bought cost S$5 and only available in Sheng Shiong supermarkets. Most of the other pineapples cost around $1.50 to $2.
