Nutrition Degree

Most people tend to take Biology / Pre-Med route. I know you can get into medical school with any major, but I wonder how well the N & D will prepare me. N & D program at my school has is with some changes and could end up comparing a graduate of BS programs in Biology / Pre-Med. Is the extra 2 years of school to get a master's degree in medical school? Can I change the information I learn in the diet, the medical school or should I go with biology standard?
