What nutrients do families need?

Answer 1

The same as any individual. Here's the wiki on it:

I would provide my family with enough macronutrients and calories in the form of carbohydrates, fats, fiber, proteins, and water.

I would also try to consume the recommended daily allowance of the micronutrients, i.e., minerals and vitamins. I would also try to consume adequate amounts of Anitioxidants and Phytochemicals.
