Soya ni ibiryo byiza bya protein nziza cyane.Kurya soya nyinshi nibicuruzwa bya soya ni ingirakamaro kumikurire yubuzima nubuzima.
Soya ikungahaye cyane ku ntungamubiri, kandi intungamubiri za poroteyine zikubye inshuro 2,5 kugeza 8 kurusha iz'ibinyampeke n'ibiribwa by'ibirayi.Usibye isukari nke, izindi ntungamubiri, nk'ibinure, calcium, fosifore, fer, vitamine B1, vitamine B2, n'ibindi. Intungamubiri zikenewe ku mubiri w'umuntu ziruta ibinyampeke n'ibirayi.Nibiryo byiza byimboga byimbuto nziza.
Ibicuruzwa bya soya nibiryo bisanzwe kumeza yabantu.Abahanga basanze kurya proteine nyinshi za soya bigira ingaruka zo kwirinda indwara zidakira nk'indwara z'umutima n'imitsi.
Soya irimo poroteyine zigera kuri 40% hamwe n’ibinure bigera kuri 20%, mu gihe intungamubiri za poroteyine z’inka, inkoko n’amafi ari 20%, 21% na 22%.Poroteyine ya soya irimo aside amine zitandukanye, cyane cyane aside amine ya ngombwa idashobora guhuzwa n'umubiri w'umuntu.Ibiri muri lysine na tryptophan biri hejuru cyane, bingana na 6.05% na 1.22%.Intungamubiri za soya ni iya kabiri nyuma y'inyama, amata n'amagi, bityo ikaba izwiho “inyama z'imboga”.
Soya irimo ibintu bitandukanye bifatika bifatika bifasha cyane ubuzima bwabantu, nka soya isoflavone, soya lecithine, peptide ya soya, hamwe na fibre yibiryo bya soya.Ingaruka zisa na estrogene ya soya isoflavone ifasha ubuzima bwimitsi kandi ikarinda gutakaza amagufwa, kandi abagore bagomba kurya proteine nyinshi za soya ziva mubihingwa.Ifu ya soya irashobora kongera imbaraga mu ntungamubiri za poroteyine no kongera intungamubiri za poroteyine nziza cyane mu mirire.
Soya ikungahaye kuri vitamine E. Vitamine E ntishobora kwangiza gusa ibikorwa bya shimi bya radicals yubusa, bikabuza gusaza kwuruhu, ariko kandi birinda pigmentation kuruhu.
