Answer:

There are seven major classes of nutrients: carbohydrates, fats, fiber, minerals, protein, vitamins, and water.

Carbohydrates - our main source of energy.

Fats - one source of energy and important in relation to fat soluble vitamins.

Roughage (Fiber) - the fibrous indigestible portion of our diet essential to health of the digestive system.

Minerals - those inorganic elements occurring in the body and which are critical to its normal functions.

Proteins - essential to growth and repair of muscle and other body tissues.

Vitamins - water and fat soluble vitamins play important roles in many chemical processes in the body.

Water - essential to normal body function - as a vehicle for carrying other nutrients and because 60% of the human body is water.

These nutrient classes can be categorized as either;

Macro-nutrients (needed in relatively large amounts) - The macro-nutrients are carbohydrates, fats, fiber, proteins, and water.

Micro-nutrients (needed in smaller quantities) - The micro-nutrients are minerals and vitamins.

The macro-nutrients (excluding fiber and water) provide energy, which is measured in Joules or kilo-calories (often just called Calories).

Carbohydrates and proteins provide 17 kJ (4 kcal) of energy per gram, while fats provide 37 kJ (9 kcal) per gram.

Vitamins, minerals, fiber, and water do not provide energy, but are necessary for other reasons.
