Question

Which of the following is/are macro-nutrient?

Answer 1

Hint: Macronutrients are the energy-producing foods that we need in greater amounts: fat, protein, and carbohydrates. Micronutrients, which mostly consist of vitamins and minerals, are similarly essential. But only absorbed in trace quantities.

Complete answer:
Carbohydrates, fats, fiber, vitamins, and water are the macronutrients. Minerals and vitamins are micronutrients.
Macronutrients are structural and energy materials (excluded fiber and water) (amino acids, which are used to make proteins, and lipids, which are used to make cell membranes and other signaling molecules). Some structural contents can be used internally to produce energy and are measured in Joules or kilocalories (often written with a C-capital in which small 'c' calories are distinguished). Carbohydrates and proteins provide energy per gramme for \[17{\text{ }}kJ\]\[\left( {4{\text{ }}kcal} \right)\], whereas the fats provide \[37{\text{ }}kJ\]\[\left( {9{\text{ }}kcal} \right)\] per gramme, whereas the energy net from each one depends on such factors as absorption and digestion, which vary considerably from situation to situation. The energy-producing substance of vitamins, minerals, fibers, and water is essential, but for other purposes. For mechanical as well as biochemical reasons fiber (i.e., not digestible materials such as cellulose) seems necessary, but unknown are exact reasons.

Note:
The macronutrients are carbohydrates, fat, and protein. These are the nutrients that you use the most. Macronutrients are the nutritive elements of food that the body requires for nutrition and to keep its environment and processes in good working order. Macronutrients are foods that contain calories or energy and are needed in significant quantities to keep the body functioning and carry out everyday tasks.
