Nutrients:

  • Food is required for the growth and maintenance of the body.

  • The food consumed varies according to the region (like hilly areas or coastal areas), age (like babies or children or old people), and physical conditions (ill health, sportsman, etc.) of the person. 

  • The substances present in the food which provide the necessary energy and nourishment for the growth, functioning, and maintenance of the body of an organism are termed as nutrients.

  • Food consists of different nutrients and each of them has a special function in the growth of the body.

 

Major Nutrients:

The major nutrients are listed as:

  1. Carbohydrates: 

  • They are the major group of nutrients that provides us energy for the functioning of the body. 

  • They are generally present in the form of sugar and starch in the food.

  • The test for the presence of carbohydrates in food can be done by adding a drop of iodine solution to the food. A blue-black colour indicates the presence of starch and carbohydrates.

  • The sources of carbohydrates in the food are whole grains like wheat, rice, vegetables, fruits, legumes, etc.

 

  1. Proteins:

  • They are the foundation for all the cells, muscles, and tissues and hence they are known as the building blocks of the body.

  • They are essential for the healthy development and repair of the muscles, tissues, organs, hormones, hair etc.

  • The test for the presence of protein in food can be done by adding two drops of copper sulphate solution and ten drops of caustic soda solution to the food. If it turns violet, it shows the presence of proteins. 

  • The sources of proteins in the food are milk, cheese, white meat like chicken, seafood, like prawns, eggs, almonds, beans, soybeans, peas, etc.

 

  1. Fats:

  • They provide the body with the required energy to do work.

  • They are harmful if taken in large quantities.

  • The presence of fat in the food can be known if the food leaves an oily stain on the paper.

  • The sources of fats in the food are from animals like meat, butter, ghee, eggs, etc. and from plants like groundnuts, vegetable oil, coconut oil, nuts, etc.

 

  1. Minerals: 

  • These are the components that are required by our body in small amounts. They are very important for the proper growth and development of the body.

  • Various minerals are required for different purposes. Like calcium for the bones and teeth, iron for red blood cells, and iodine for the functioning of the thyroid gland.

  • The sources of some of the minerals in the food are Calcium in milk, eggs etc., phosphorus in milk, bananas etc., iron in spinach, apples etc., and iodine in fish, ginger etc.

 

  1. Vitamins: 

  • These are yet another group of substances that keeps the body safe from any diseases.

  • They are also essential for the health of the eyes, bones, teeth, and gums.

  • There are different types of vitamins with specific functions and they are required in small quantities only. Vitamin A is for the eyes, vitamin D for bones and teeth, and vitamin C for fighting diseases.

  • The sources of various vitamins in the food are Vitamin A in mango, carrot, papaya, fish oil, milk etc., vitamin B in rice, wheat etc., vitamin C in lemon, orange, tomato etc., vitamin D in milk, fish, eggs etc.

 

  1. Roughage: 

  • These are the dietary fibres that are present in the food. They are mainly provided by the plant's products and they don’t provide any nutrients to the body. 

  • Their role is to help the body remove the undigested food.

  • Water is yet another component of food that helps in the absorption of nutrients and removing the waste in the form of urine and sweat. 

  • The roughages is present in whole grains like oats, vegetables like beans, carrots etc, fruits like apples, pears etc.

 

Balanced Diet: 

  • Most of the food that is consumed has one nutrient as a major part like rice has more carbohydrates. So, for the proper functioning and development of the body and good health, a little bit of each nutrient is required.

  • A diet that has the right balance of the essential nutrients required by the body like carbohydrates, protein, fats, minerals and roughage is termed a balanced diet. A balanced diet contains whole grains like rice or wheat for carbohydrates, pulses like dal and meat or egg for proteins, and vegetables for minerals, vitamins, and fibres. 

  • Eating food that has too much of fats, like fried food or sweets, must be avoided as this can increase the body weight leading to a condition called obesity.

 

Deficiency Diseases: 

  • Having a diet which is lacking in any one of the nutrients may lead to its deficiency in the body. 

  • The diseases that are caused due to the deficiency of a nutrient over a long period of time are termed deficiency diseases. 

  • These diseases have various symptoms according to the nutrient that is deficient. This condition can be overcome by having a balanced diet.
