See, it depends completely on your preference and interests. Naturopathy falls under medicine and health, but it is not considered a suitable career option in India now, as it is a really new course. In India, there are a handful of colleges on naturopathy offering courses at various levels – diploma, undergraduate and postgraduate. At the same time, licensed naturopathic physicians, however, have to complete a four-year program at the graduate level. You might be able to study and practice various practices nutrition therapy, acupuncture, homeopathic medicine, natural childbirth, and herbal/botanical medicine etc. It is most prevalent with alternative means of medicine, and is a budding and upcoming field. Engineering, on the other hand, is a tried and tested field. and you have a solid chance of building up a strong career with a foundation as good as engineering. There are various domains in engineering, from mechanical to civil to CS, so, I would recommend you think about what you really want to do. If you like medicine and relalted fields, go for the former; Otherwise, the latter would provide a strong support for your future. All the best!
