WHAT IS NUTRITION Nutrition is the science that interprets the interaction of nutrients

and other substances in Food (e.g. phytonutrients, anthocyanins, tannins, etc.) in relation to maintenance, growth, reproduction, health and disease of an organism. It includes food intake, absorption, assimilation, biosynthesis, energy metabolism, catabolism and excretion.

The diet of an organism is what it eats, which is largely determined by the availability, processing and palatability of foods. A healthy diet includes preparation of food and storage methods that preserve nutrients from oxidation, heat or leaching, and that reduce risk of food-born illnesses.

SOME DEFINITIONS…… CATABOLISOM: Catabolism is the set of metabolic pathways that

breaks down molecules into smaller units to release energy.Anabolism: Anabolism is the set of metabolic pathways that

construct molecules from smallest units. These reaction require energy.

Absorption: it is a common physical phenomenon or process in which atoms, molecule ,ions enter some bulk phase-gas ,liquid, solid material.

Biosynthesis: it is a multi step enzyme catalyzed process where subtracts are converted into more complex product.

History The first recorded dietary advice, carved into a Babylonian

stone tablet in about 2500 BC, cautioned those with pain inside to avoid eating onions for three days. Scurvy, later found to be a vitamin C deficiency, was first described in 1500 BC in the Ebers Papyrus.

Carbohydrate A carbohydrate is a biological molecule consisting of carbon (C), hydrogen (H) and oxygen (O) atoms, usually with a hydrogen: oxygen atom ratio of 2:1 (as in water); in other words, with the empirical formula Cm(H2O)n (where m could be different from n).Some exceptions exist; for example, deoxyribose, a sugar component of DNA,has the empirical formula C5H10O4. Carbohydrates are technically hydrates of carbon; structurally it is more accurate to view them as polyhydroxy aldehydes and ketones.

Glucose is the simplest form (unit) of carbohydrate. Its called monosaccharide.

mainly found in Grain based product (e.g.: Rice, flour, noodles, bread), honey, any fruits ,vegetable

1 gram carbohydrate provided 17 kJ or 4 cal energy

It may be disaccharide ,trysaccharide, polysaccharide

proteinProteins are essential nutrients for the human body.

It is a essential part of daily food to make & protect our body.

There are nine essential amino acids which humans must obtain from their diet in order to prevent protein-energy malnutrition. They are phenylalanine, valise, threonine, tryptophan, methionine, leucine, isoleucine, lysine, and histidine

Its simplex form is amino acid.

Mainly found in –I. Animal- milk, fish, egg, meat II. Vegetable- soya bin, spinach,

legume, blackberry, pumpkin seed ,nuts. Cashew nuts, peas

1 gram carbohydrate provided 17 kJ or 4 cal energy

Daily Protein intake capacity

DeficiencyProtein deficiency and malnutrition can lead to variety of ailments including mental retardation and kwashiorkor. Symptoms of kwashiorkor include apathy, diarrhea, inactivity, failure to grow, flaky skin, fatty liver, and edema of the belly and legs. This edema is explained by the action of lipoxygenase on arachidonic acid to form leukotrienes and the normal functioning of proteins in fluid balance and lipoprotein transport.PEM is fairly common worldwide in both children and adults and accounts for 6 million deaths annually. In the industrialized world, PEM is predominantly seen in hospitals, is associated with disease, or is often found in the elderly.

FATFats are a wide group of compounds whose basis is in long-chain organic acid called fatty acid. It is mainly two type saturated and non saturated .

Saturated fat - have no double bonds between carbon chain

Non saturated fat-have one or more than double bond between the carbon chain

Some fatty acid cannot synthesized in our body (e.g. alpha linolenic acid, linolenic acid). They called EFA .

Main source are –1. Vegetable- nuts, grain oil, oil2. Animal- dairy product , meat, egg , etc.

1 gram fat provide 34 kJ energy

vitamin

Vitamin • Vitamin is an organic compound which is a vital nutrient ,that

an organism required limited amount.

• The term vitamin was derived from "vitamine," a compound word coined in 1912 by the Polish biochemist Kazimierz Funk when working at the Lister Institute of Preventive Medicine. The name is from vital and amine, meaning amine of life, because it was suggested in 1912 that the organic micronutrient food factors that prevent beriberi and perhaps other similar dietary-deficiency diseases might be chemical amines. This was true of thiamine, but after it was found that other such micronutrients were not amines the word was shortened to vitamin in English.
