Amaqanda enkukhu ingenye yemikhiqizo ebaluleke kunazo zonke kubantu. Ukwakhiwa kweqanda lezinkukhu kubandakanya okudingekayo ekusebenzeni kwamaprotheni omzimba namafutha, kanye nezingxenye eziphilayo eziphilayo eziphilayo - amavithamini , izakhi ezincane nezincane.
Ukwakhiwa kwamakhemikhali amaqanda ezinkukhu
Ukwakhiwa kwamakhemikhali weqanda lezinkukhu kuqukethe:
- amanzi 74%;
- Amaprotheni - 12.5%;
- amafutha - 12%
- ama-carbohydrate - 0,5%;
- izakhi zamaminerali namavithamini - 1%.
Ukwakhiwa kweprotheyini yeqanda lezinkukhu kuhluke ekubunjweni kwe-yolk, ngoba ayinakho amafutha futhi kunomthamo wamanzi aphezulu. Futhi i-yolk, ngokungafani namaprotheni, iqukethe amino acid ambalwa kakhulu. Inani lamandla amaqanda ezinkukhu liyi-47 kcal (157 kcal nge-100 g). Ingxenye ephawulekayo yokuqukethwe kwekhalori yeqanda (75%) ingeyesikhupha.
Ama-protein ahlinzeka ngokudla okunomsoco okwenziwe iqanda lezinkukhu. Ama-amino acids emaqanda enkukhu agcinwa ngokulingana, ngakho-ke athola umzimba cishe cishe 100%. Ngenxa yalesi sizathu, abantu abancinci kanye nabadlali bama-muscle-building ngokuvamile basebenzisa amaqanda abamhlophe kuphela.
I-yolk yeqanda lezinkukhu iyingxenye eyodwa kwezintathu zamafutha, ingxenye ebaluleke kakhulu ye-fatty acids insaturated ebaluleke kakhulu. Izingxabano mayelana nezingozi nezinzuzo ze-isikhupha samaqanda phakathi kwababusi bezilwane zifuna uketshezi lwe-cholesterol. Noma kunjalo, kwelinye iqanda akulona kakhulu - lingaphansi kwesilinganiso sansuku zonke. Ngaphezu kwalokho - i-yolk cholesterol "ayitholakali" ngenye ingxenye yeqanda - i-lecithin.
Ukusetshenziswa kwamaqanda kwandisa amavithamini amaningi (A, E, PP, D, H, K, Group B), kanye nokubunjwa kwamaminerali, okufaka i-calcium, i-phosphorus, i-magnesium, i-potassium, i-sodium, isulfure, insimbi nezinye ezidingekayo empilweni izakhi.
Ukukhuluma ngokubunjwa kweqanda lezinkukhu, awukwazi ukukhohlwa ngegobolondo lalo. Ingxenye eyinhloko yegobolondo - i-calcium, kodwa ihlanganisa ezinye izinto ezingu-30 ezisebenzayo zamaminerali.
Ukulimala kwamaqanda ezinkukhu
Ngenxa ye-ovomucoid amaprotheni emaqanda, lo mkhiqizo ukhululekile kakhulu. I-Ovomukoid ibangela ukuhluleka ekwenzeni ama-enzyme ngama-pancreas, okuholela ekugayeleni kokudla okungaphelele kanye nokukhushulwa kwezimpawu zokugula. Nciphisa okuqukethwe ekudleni kwamaqanda kufanele kube ne-hypertension, isibindi sesifo, izinso kanye ne-gallbladder, izifo zesikhumba. Ngaphezu kwalokho, amaqanda angabuye abe umthombo wama-bacterium e-pathogenic. Enye ye-pathogenic kakhulu i-salmonella. Ukuvikela kulokhu okuncane, odokotela batusa ukupheka amaqanda okungenani amaminithi angu-8 emva kokubilisa.
