I wouldn't shoot races with it but for scenery, portraits, etc. I always do.
It does not mater as each time you save the file JPG losses data. Its a fact of using JPG. You will not loss data if you open the JPG and then save it as tiff or bmp file. If you save to a new file each time you save your old files but if you use JPG each granulation will be of poorer quality. JPG recompresses the file on each save.
