WHAT IS NUTRITION 
Nutrition is the process of acquiring energy and food materials. Nutrition is the provision, to 
cells and organisms, of the materials necessary (in the form of food) to support life. The human 
body contains chemical compounds, such as water, carbohydrates (sugar, starch, and fiber), 
amino acids (in proteins), fatty acids (in lipids), and nucleic acids (DNA and RNA). These 
compounds in turn consist of elements such as carbon, hydrogen, oxygen, nitrogen, 
phosphorus, calcium, iron, zinc, magnesium, manganese, and so on. All of these chemical 
compounds and elements occur in various forms and combinations (e.g. hormones, vitamins, 
phospholipids, hydroxyapatite), both in the human body and in the plant and animal organisms 
that humans eat. 
What is Nutrient-A nutrient is a chemical that an organism needs to live and grow or a 
substance used in an organism’s metabolism which must be taken in from its environment. 
They are used to build and repair tissues, regulate body processes and are converted to and 
used as energy. 
Classification of Nutrient-: There are six major classes of nutrients- Carbohydrates, protein, 
vitamins, minerals, fats and water. 
CARBOHYDRATE 
Nature- A Carbohydrate is an organic compound that consists only of Carbon, Hydrogen and 
Oxygen. It is divided into four chemical groupings: monosaccharides, disaccharides, 
oligosaccharides, and polysaccharides. For example, blood sugar is the monosaccharide 
glucose, table sugar is the disaccharide sucrose, and milk sugar is the disaccharide lactose. 
Function- Carbohydrates perform numerous roles in living organisms. Polysaccharides serve for 
the storage of energy (e.g., starch and glycogen), and as structural components (e.g., cellulose 
in plants and chitin in arthropods). The 5-carbon monosaccharide ribose is an important 
component of coenzymes (e.g., ATP, FAD, and NAD) and the backbone of the genetic molecule 
known as RNA. The related deoxyribose is a component of DNA. Saccharides and their 
derivatives include many other important biomolecules that play key roles in the immune 
system, fertilization, preventing pathogenesis, blood clotting, and development. 
Source-Starch (such as cereals, bread, and pasta) or simple carbohydrates, such as sugar (found 
in candy, jams, and desserts). 
FATS 
Fats consist of a wide group of compounds that are generally soluble in organic solvents and 
generally insoluble in water. Fats can be categorized into saturated fats and unsaturated fats. 
Function-Fat provides needed energy. It is difficult to eat the large amounts of food in a very 
low fat diet to get all the energy you need. 
Fat is needed to prevent essential fatty acid deficiency. 
 Fat is needed so your body can absorb the fat soluble vitamins A, S, E, K, and prevent 
deficiencies of these vitamins. 
 Fat provides flavor and texture to help prevent food from being bland and dry. 
Fat may help your body produce endorphins (natural substances in the brain that 
produce pleasurable feelings). 
Source- Mutton, Milk, Egg Etc. are rich in fat.
