What foods give you spots?

im 14 years old and i have a lot of spots. i would like to get rid of them for the summer as i am my aunties bridesmaid and i have had the spots for a long time. i have tried all the different creams like clearasil and quinoderm but they still havnt cleared. i heard that it is chocolate that gives you spots and thought that might be the cause of my spots as i am a chocoholic. i would like to know exactly what foods and drinks give you spots so i know whether i need to cut down on them foods or not. please help me as i dont want to be spotty for the rest of my life xxxx
