### Macronutrients
Ana bayyana macronutrients a hanyoyi da yawa.

* The chemical elements humans consume in the largest quantities are carbon, hydrogen, nitrogen, oxygen, phosphorus, and sulphur, summarized as CHNOPS.
* The chemical compounds that humans consume in the largest quantities and provide bulk energy are classified as carbohydrates, proteins, and fats. Water must be also consumed in large quantities but does not provide caloric value.
* Calcium, sodium, potassium, magnesium, and chloride ions, along with phosphorus and sulfur, are listed with macronutrients because they are required in large quantities compared to micronutrients, i.e., vitamins and other minerals, the latter often described as trace or ultratrace minerals.

Macronutrients suna samar da makamashi:

* Carbohydrates mahadi ne da aka yi da nau'ikan sukari. Ana rarraba carbohydrates bisa ga yawan sukari: monosaccharides (kamar glucose da fructose), disakacharides, oligosaccharides, da polysaccharides.
* Protein sune mahadi na kwayoyin halitta waɗanda suka ƙunshi Amino acid da aka haɗa da haɗin peptide. Tun da jiki ba zai iya ƙera wasu amino acid ba (wanda ake kira amino acid mai mahimmanci), abincin dole ne ya samar da su. Ta hanyar narkewa, sunadarai suna rushewa ta hanyar proteases zuwa amino acid kyauta.
* Fats sun kunshi kwayar glycerin tare da ƙwayoyin ƙwayoyin cuta guda uku da aka haɗe. Kwayoyin acid mai ƙwayoyin suna ƙunshe da ƙungiyar -COOH da aka haɗa da sarkar hydrocarbon marasa reshe waɗanda aka haɗa ta hanyar haɗin guda ɗaya (saturated fatty acids) ko kuma ta hanyar haɗin biyu da ɗaya (unsaturated fattid acids). Ana buƙatar kitse don ginawa da kula da Membrane na tantanin halitta, don kula da yanayin zafin jiki mai ɗorewa, da kuma ci gaba da lafiyar fata da gashi. Saboda jiki ba ya ƙera wasu ƙwayoyin ƙwayoyin cuta (wanda ake kira ƙwayoyin mai ƙwayoyin), dole ne a samo su ta hanyar abincin mutum.

### Ƙananan Ƙasashe
Micronutrients sune mahimman abubuwan abinci da ake buƙata a cikin adadi daban-daban a duk tsawon rayuwa don yin aiki da ayyukan metabolism da na jiki.

* Ma'adanai na abinci, kamar su potassium, sodium, da baƙin ƙarfe, abubuwa ne na asali a Duniya, kuma ba za a iya haɗa su ba. Ana buƙatar su a cikin abincin a cikin microgram ko milligram. Yayin da tsire-tsire ke samun ma'adanai daga ƙasa, ma'adinai na abinci suna fitowa kai tsaye daga tsire-shuke da aka cinye ko a kaikaice daga tushen dabbobi masu cin abinci.
* Vitamins sune kwayoyin halitta da ake buƙata a cikin microgram ko milligram. An fara kafa muhimmancin kowane Bitamin abinci lokacin da aka ƙaddara cewa cuta za ta tasowa idan wannan bitamin bai kasance a cikin abincin ba.

## Muhimmanci

### Abubuwan gina jiki masu mahimmanci
Wani abu mai gina jiki shine abin gina jiki da ake buƙata don aikin jiki na yau da kullun wanda ba za a iya haɗa shi a cikin jiki ba - ko dai a ko'ina ko a cikin isasshen yawa - don haka dole ne a samu daga tushen abinci. Baya ga ruwa, wanda ake buƙata a duk duniya don kula da homeostasis a cikin dabbobi masu shayarwa,  abubuwan gina jiki masu mahimmanci suna da mahimmanci ga matakai daban-daban na metabolism da kuma kiyayewa da aiki na kyallen takarda da gabobin.  Abubuwan gina jiki da ake la'akari da su da mahimmanci ga mutane sun hada da amino acid tara, fatty acid guda biyu, bitamin goma sha uku, ma'adanai goma sha biyar da choline. Bugu da kari, akwai kwayoyin da yawa waɗanda ake la'akari da abubuwan gina jiki masu mahimmanci tunda suna da mahimmanci a wasu jihohin ci gaba da cututtukan cututtuka.&nbsp;
