Why is dry matter necessary for sustaining a body and not just nutrients?

Question

For example, why do bodies biologically need food (that contains dry matter) instead of surviving off nutrients from vitamin supplements?

Answer 1

Because the "dry matter" includes proteins for building the various tissues of the body, sugars for energy and fats for energy and nerve growth. Vitamins and minerals are only needed in small quantities to fill certain specific needs which can normally be gotten from a rich variety of foods or a very careful selection of a few foods (e.g. beans plus rice in vegetarian diet to get balanced proteins.)
Taking a vitamin/mineral supplement merely guarantees that you have no shortages and most of the stuff in the pill goes out in your pee.

Answer 2

you need calories for energy. energy comes from carbs, fats, and proteins. without these many if not all of your main organs (ie heart, liver, brain) would not survive. supplements are just that. supplements to kind of be a backup if you're not getting all the nutrients you should be.

Answer 3

I believe a draft will have to be obligatory and the sons or daughters of the present president will have to be the primary within the entrance strains to exhibit their patriotism fairly just like the Royal household of Great Britain that's a culture.
