Nutrition Is Nourishment Or Energy That Is Obtained From Food Consumed Or The Process Of Consuming The Proper Amount Of Nourishment And Energy
Nutrition is nourishment or energy that is obtained from food consumed or the process of consuming the proper amount of nourishment and energy.
Good nutrition is an important part of leading a healthy lifestyle. Combined with physical activity, your diet can help you to reach and maintain a healthy weight, reduce your risk of chronic diseases (like heart disease and cancer), and promote your overall health.
A heterotrophic organism (or heterotroph) can obtain its food from other organisms in three ways. So, the heterotrophic mode of nutrition is of three types:
1. Saprotrophic nutrition :
2. Parasitic nutrition, and
3. Holozoic nutrition.
Saprotrophic nutrition is that nutrition in which an organism obtains its food from decaying organic matter of dead plants, dead animals and rotten bread, etc. 'Sapro' means 'rotten', so a saprotrophic organism draws its food from rotting wood of dead and decaying trees, rotten leaves, dead animals and household wastes like rotten bread, etc.
The parasitic nutrition is that nutrition in which an organism derives its food from the body of another living organism (called its host) without killing it. The organism which obtains the food is called a 'parasite', and the organism from whose body food is obtained is called the 'host'. We can now say that: A parasite is an organism (plant or animal) which feeds on another living organism called its host.
• Carbohydrates are compounds of tremendous biological importance:
– they provide energy through oxidation
– they supply carbon for the synthesis of cell components – they serve as a form of stored chemical energy
– they form part of the structures of some cells and
Tissues
Proteins are essential nutrients for the human body.[1] They are one of the building blocks of body tissue. Proteins are complex organic compounds. They are macromolecules or bio molecules composed of amino acids linked by peptide bond.
Fat is a component in food. fat is an important part of a healthy diet.
