Hi Amie! Good to hear that you love biology. if you are interested in continuing research in "Nutrition", biochemistry is better option. You can focus on clearing integrated programs by IISC and NCBS, Bangalore. If not you need to aim at clearing CSIR/ICMR entrance exams. Writing JNU combined entrance would also be a good option. All the best.
