Proteins are made up of hundreds or thousands of smaller units called amino acids, which are attached to one another in long chains.
Proteins
(i) Milk, fish, meat, cheese and eggs are the main sources of animal proteins. Vegetable proteins can be obtained from legumes including pulses and beans.
(ii) Proteins are required for growth and repairing in our body. They help in building new tissues. They also account for tough, fibrous nature of hair and nails and for the structure of muscles. They are a part of our blood and help in proper functioning of our body.
(iii) Large amount of protein is needed for building new tissue in short period, such as during infancy, pregnancy or when mother is nourishing a child.

Proteins help our body fight against infections
Proteins are an essential macronutrient that helps our body to perform various functions. One of the crucial roles played by proteins is to assist our immune system in fighting against infections. The immune system is our body's defense mechanism that protects us from harmful pathogens such as bacteria, viruses, and fungi. Proteins help the immune system in several ways:
Antibodies
Antibodies are specialized proteins that the immune system produces to identify and neutralize harmful pathogens. These proteins are created by white blood cells called B cells. Antibodies work by binding to specific sites on the surface of pathogens, making them inactive and allowing the immune system to eliminate them.
Cytokines
Cytokines are proteins that help to regulate the immune response. They are produced by various cells in the immune system, including white blood cells and other immune cells. Cytokines help to coordinate the response of different immune cells and can trigger the production of other immune system components.
Enzymes
Enzymes are proteins that catalyze chemical reactions in the body. Some enzymes play a vital role in the immune system by breaking down harmful pathogens or by activating other immune system components.
Amino acids
Proteins are made up of amino acids, which are the building blocks of life. Some amino acids are essential, meaning that our body cannot produce them and must obtain them from food. These essential amino acids are particularly important for the immune system, as they are required to produce antibodies and other immune system components.
In conclusion, proteins play a crucial role in maintaining a healthy immune system and fighting against infections. It is essential to include protein-rich foods in our diet to ensure that our body has the necessary resources to maintain a robust immune system.

Most food items, usually, have more than one nutrient. The major nutrients in our food are named carbohydrates, proteins, fats, vitamins and minerals. In addition, food contains dietary fibres and water which are also needed by our body. It is important to eat a wide range of food in order to stay healthy.
Nutrients are essential to perform all daily and metabolic activities. Below are the nutrients needed in our daily life.
