Different foods contain different amounts of elements needed by our bodyfor the above four functions. These vital elements are called nutrients. So, the diet which contains all these essential nutrients in right quantity will be balanced diet for us. The essential nutrients required by our body are: carbohydrates, proteins, fats, minerals and vitamins.

Carbohydrates and fats mainly provide energy to our body. Wheat, rice, potato, banana, etc. are very rich in carbohydrates. Jaggery or sugar is another source of carbohydrates. Ghee, butter, oils, cream and milk are full of fats.

Proteins help the body to grow. They also help it to replace the dead or worn-out parts and to repair the damaged parts. Children need more proteins because their bodies have to grow rapidly. Pulses, milk, cheese, curd, egg, fish and meat are rich in proteins.

Vitamins and minerals are present in milk, cheese, fruits, vegetables and meat etc. Vitamins keep our eyes, bones, gums, etc. healthy. Minerals like phosphorus and calcium are necessary for the formation of healthy bones and teeth, while iron compounds are required for the formation of red blood cells.

So, a balanced diet is one which is suitable in all respects, sufficient in food value as well as adequate in quality and quantity according to the needs of a body. To keep our body healthy and fit, we must follow the ‘balanced diet’ principle. Our ancient medical system of Ayurveda also emphasizes this principle of balanced diet.

“No medicines are required by a person who correctly follows the prescribed diet scheme. But one who does not follow this principle of diet cannot be helped even by hundreds of medicines.”

We should therefore know what to eat and follow the diet scheme as far as possible. Children should also be given their diet according to this principle. In fact, everyone should follow the diet system properly.
