this is an inquiry for a friend, who practices a primal diet and wants to work in the nutrition industry

what are the job prospects?
what qualifications are needed?
what is the reality of work in the industry?
what is your view of the (naturopathic nutrition diploma course at the college of naturopathic medicine)
are there practices where nutritionists offer paleo/primal advice?
Can one make a living by advocating such a lifestyle? You couldn't not get away with this in the NHS, I met an NHS nutritionist who turned round and said I would get heart disease following a high fat low carb diet.

advice would be appreciated.
