A nutrient can be defined as components that are needed by our body to grow, survive and carry on different daily activities.Our food contains mainly five major kinds of nutrients namely vitamins, minerals, carbohydrates, proteins and fats. Additionally, food also contains water and dietary fibres/roughage and water which are also required by our bodies.

Ex – 2.1 – What Do Different Food Items Contain?

Foods have energy and non-energy components.

Our cells need energy (calories) to function. The energy components of food include:

  • carbohydrates (sugars and starches)
  • proteins
  • lipids (fats)

The non-energy components include:

  • vitamins
  • minerals
  • dietary fibre
  • water

Carbohydrates : Carbohydrates are the body’s main source of energy and the sole fuel for the brain.

Proteins : Proteins are necessary for building, repairing and renewing all the organs of the body.

Fats : Fats, also called lipids, play a role in the transport of certain vitamins and provide the body with essential fatty acids.

Fats are found in:

  • meat and cured meats (deli meats)
  • poultry skin
  • fried foods
  • cheese
  • nuts and seeds
  • butter and oils
  • sauces, salad dressings (vinaigrettes), mayonnaise
  • pastries
  • chocolate
  • etc.

When eaten in excess, fats, particularly saturated and trans fats, can lead to high blood cholesterol levels and obesity.

Vitamins and Minerals : The daily required amounts of vitamins and minerals is low but essential to life.

The body’s daily need for vitamins and minerals is generally satisfied by a balanced diet that includes a variety of foods from each food group.

No single food contains all essential vitamins and minerals in sufficient amounts to meet the body’s needs. That is why it is vital to eat different foods each day.
