Akukho nakuphi na ukutya okuthandwayo kwaye kwangaxeshanye kuphikisana njengenyama. Ngokomyinge, amaJamani atya malunga neekhilogram ezingama-60 ngonyaka. I-German Society for Nutrition (DGE), ngakolunye uhlangothi, incoma ukutya ubuninzi be-600 grams yenyama ngeveki. Oko kuya kuba malunga neekhilogram ezingama-31 ngonyaka. Abathengi bakhetha inyama yehagu, ilandelwa yinkukhu, inyama yenkomo kunye nenyama yenkomo. Isiqingatha salo sisetyenziswa ngendlela ecutshungulwayo njengesoseji okanye ezinye iimveliso zenyama.
Ezi zondlo zisenyameni
Inyama inezondlo ezininzi ezixabisekileyo. Ibonelela ngeprotheyini ekumgangatho ophezulu, i-iron, iivithamini B, kunye neeminerali. Noko ke, namhlanje akuseyomfuneko ukuba siyitye inyama ukuba sifuna ukutya ngendlela esempilweni kuba zonke izondlo zikwafumaneka nakokunye ukutya. Iingcali nazo ziyavuma ukuba inyama eninzi kunye nesoseji inokuba yingozi kwimpilo yakho.
Iiprotheyini ezininzi, kodwa kunye neepurines ezininzi
Inyama ye-muscle ecocekileyo iqulethe ngaphezu kweepesenti ze-20 zeprotheni. Ngoko ke ityebile kwizinto ezibalulekileyo, oko kukuthi, i-amino acids ebalulekileyo kwaye, kunye neprotein yeqanda kunye nobisi, yenye yeeprotheni ezinexabiso eliphezulu lebhayoloji. Iprotheyini yezilwanyana ifana kakhulu neprotheyini yomntu kwaye ngoko ke inokufunxwa lula kwaye iqhutywe ngumzimba. Ngenxa yeprotheyini ephezulu, nangona kunjalo, inyama inika kwakhona i-purines eninzi. Ezi ziiprotheyini eziphuma kwimveliso ezahlulahlulwa zibe yiuric acid emzimbeni kwaye ziqhele ukukhutshelwa emchameni. Kubantu abaye baphazamisa i-uric acid metabolism, ukutya okutyebileyo kwinyama kunokukhokelela ekuhlaselweni kwegout.
Kungcono umhlophe kunenyama ebomvu
Inyama ebomvu efana nenyama yenkomo kunye nehagu ityebile kwi-iron, efunekayo ekwenzeni iiseli ezibomvu zegazi. Nangona kunjalo, inyama ebomvu eninzi ikhuthaza ukukhula komhlaza wekoloni, izifo zentliziyo kunye nesifo seswekile. UMbutho wezeMpilo weHlabathi (i-WHO) wawuchaza njenge "mhlawumbi i-carcinogenic". Inyama emhlophe, okt inyama yenkukhu iyagaywa ngakumbi, isezantsi ngeekhalori, kwaye isezantsi namafutha.
Umxholo wamafutha uyahluka
Umthamo wamafutha enyama uyahluka ngokuxhomekeke kuhlobo lwenyama kwaye kuxhomekeke nasekutyeni kwezilwanyana. Ngokubanzi, umxholo we-fat uye waqhubeka nokuwa kwiminyaka yamuva. Eyona nto ibalulekileyo apha luhlobo lwamafutha - i-acids enempilo engapheliyo kunye ne-fatty saturated fatty acids. Inyama yenkukhu idla ngokuba nomlinganiselo ophezulu wamanqatha angaxutywanga kunenyama ebomvu.
Kwelinye icala, icholesterol ayitshintshi. Ngokuxhomekeke kuhlobo lwenyama kunye nokusikwa, iguquguquka phakathi kwe-60 kunye ne-80 milligrams ye-cholesterol nge-100 grams. Inyama yezinto eziphilayo ikhethwayo ngenxa yezizathu zokuziphatha kwaye ayifuni iyeza le-prophylactic, kodwa akukho nto ingcono ngokubhekiselele kwikhwalithi.
