Which of the following is a Macronutrient for human body ?

  • A.Zinc
  • B.Vitamin D
  • C.Protein
  • D.Iron

Answer: C

The macronutrient is protein.

Macronutrients are nutrients the body needs in large amounts: carbohydrates, proteins and fats, which supply energy and build tissue.

Zinc and iron are minerals and vitamin D is a vitamin; all three are micronutrients, needed in only small quantities.

Micronutrient deficiencies still matter greatly, as with iron-deficiency anaemia, but the amounts needed are measured in milligrams or micrograms, not grams.
