Rambutan benefits are also possible because of the high fiber content of the fruit. The fiber helps sweep the lower intestinal tract from accumulated toxins and also aids in making you feel full faster so you can regulate your food intake and prevent overeating. rambutan fruit is best eaten raw. Simply peel off the hairy skin and pop the white juicy flesh into your mouth. But be careful not to eat the bitter seed that is hidden inside the white flesh.
