Nutrients:
Foods contain a variety of nutrients required by our bodies every day.
On an average, we need a daily dose of approximately 40 odd nutrients. That sounds like a lot if it weren't for the fact that each of these nutrients is available in the foods we ordinarily eat. The nutrients essential for normal body functioning include Carbohydrates,Fat, Protein,Vitamins,Minerals,Fibre and Water.

Interestingly, our bodies require some nutrients in much larger quantities than others. These nutrients-carbohydrates,protein and fat- are collectively known as MACRONUTRIENTS.

Macronutrients give us energy in the form of kilocalories[kcal]

Do you know why we tend to eat more of rice,wheat,ragi,jowar and bajra than meat,fish,fruit or vegetables?

Cereals like rice, wheat,etc. are abundant in carbohydrates [the body's main energy supplier] and therefore in substantial quantity.

Conversely, nutrients that our bodies need in lesser quantities are called as micro nutrients. Vitamins and minerals are the micronutrients in our diet. Often dismissed, water and fibre are the two other important nutrients that play a pivotal role in our bodies.

ENERGISERS:
Rice,wheat,ragi,noodles

Rice, wheat,ragi,noodles,etc all come under the broad category, cereals.Cereals are predominantly packed with carbohydrates. They also have some amount of vitamins and minerals[eg. ragi is rich in calcium and rice is a good source of vitamin B]

Although not a cereal,potato also contains a considerable amount of carbohydrates and therefore calories. In fact, one medium-sized potato-approx-100g- contains the same amount of carbohydrates and calories as a teacup of cooked rice.
