                                    It is well known that stars orbited by giant planets have higher
abundances of heavy elements when compared with average field dwarfs. A
number of studies have also addressed the possibility that light element
abundances are different in these stars. In this paper we will review
the present status of these studies. The most significant trends will be
discussed.
