Nick’s diet consists mainly of fish. Which of the following is the major food nutrient in his diet? A. carbohydrates B. vitamins C. water D. proteins E. fats

I believe the answer is vitamins or fats.

Explanation:

Fish is very good for you! It comes with all sorts of nutrients. There is vitamin D and B2 as well as Omega-3 fatty acids in fish. (There are a lot of other stuff it has but i believe those are the big ones)

That is why i would say it is either fats, or vitamins.

Hope this helps.
