I actually did a double major in nutrition and psychology ( neuroscience) and finished it 10 years ago. I will give you several paths that you may take from experience with fellow classmates who had similar interests .
Dietician/ nutritionist -get involved in health promotion and research in nutrition and develop research skills through a masters in community / public health or clinical epidemiology to answer some of the questions that you are posing. Many of my friends in nutrition got accepted into a one year dietician program and became a dietician in a year. You can work as a hospital dietician and really get involved in changing a patient's diet to assist in their recovery both inside and outside of the hospital. After becoming a dietician, you can consider doing integrative health as suggested above. You cAn also do a research based career as a nutritionist and study these types of topics in more detail through years of work completing masters, PhDs post doc, etc
Naturopathic medicine program is a program to consider to become a certified naturopath. I am unsure if they have funding for research in this area but I think that they would be me open to consider ideas do research In this area.
For myself. I did some research work in clinical epidemiology - one part involved doing a literature review on vitamin d deficiency and it's connection with type 1 diabetes. After that I went to medical school and am in a family medicine residency. Right now I am thinking of a career in public health informatics. So my path is not very traditional and my interest have changed abit over the years.
