    A nutrient is either a chemical element or compound used in an organism's metabolism or physiology. Six nutrient groups exist and are broadly classified into those providing energy, and those used as components in the body or cellular structures.[citation needed] A nutrient is essential to an organism if it cannot be synthesized in the organism and must be obtained from a food source.

    ~ Carbohydrates are compounds made up of sugars. Carbohydrates are classified by their number of sugar units: monosaccharides (such as glucose and fructose), disaccharides (such as sucrose and lactose), oligosaccharides, and polysaccharides (such as starch, glycogen, and cellulose).

    ~ Proteins are organic compounds that consists of the amino acids joined by peptide bonds. The body cannot manufacture some of the amino acids (termed essential amino acids); the diet must supply these. In nutrition, proteins are broken down through digestion back into free amino acids.

    ~ Fats consist of a glycerin molecule with three fatty acids attached. Fatty acids are unbranched hydrocarbon chains, connected by single bonds alone (saturated fatty acids) or by both double and single bonds (unsaturated fatty acids). Fats are needed to keep cell membranes functioning properly, to insulate body organs against shock, to keep body temperature stable, and to maintain healthy skin and hair. The body does not manufacture certain fatty acids (termed essential fatty acids) and the diet must supply these.

    ~ Minerals are generally trace elements, salts, or ions such as copper and iron. These minerals are essential to human metabolism.

    ~ Vitamins are organic compounds essential to the body. They usually act as coenzymes or cofactors for various proteins in the body.

    ~ Water is an essential nutrient and is the solvent in which all the chemical reactions of life take place.

    nutrient component 詳細見樓上, 我覺得佢解得唔錯

    加多少少extra info 比你

    energy content of nutrients:

    only protein, carbohydrate fat and alcohol can provide energy to support our daily activity (ie metabolism).

    for every g of the these metabolic fuels, they can provide certain amount of energy (in KJ)

    Carbohydrate ; 17

    protein; 16

    fat; 37

    alcohol; 29

    although alcohol is a fairly high energy component, it is not recommended to obtain your daily energy intake from alcohol ONLY as alcohol is energy dense but it is lack of many other essential nutrients, which may cause malnutrition if too much alcohol is consumed

    Fibre (US: Fiber)

    fibre is also a type of carbohydrate required in our diet.

    unlike other carbohydrate, our body do not have the mechanism to digest fibre. so fibre will remain undigested until they reach the large intestine, which some of the bacteria living in caecum of large intestine have the ability to digest it.

    but as we do not have large amount of these bacteria living in our caecum as many other herbivores and our body does not have a good physiology structure in large intestine to absorb monosaccharides, usually these monosaccharides will be leaving our body through the bowel activity.

    in human, the main use of fibres in diet is to bulk up the food we eat. by bulking up the food, they are easier to pass through our digestive tract and this prevents constipation.
