Zipatso za chivwende kuchokera ku malo owona za botani zimayimira mabulosi akuluakulu onyenga, omwe amalemera kufika pa 20 - 25 kilogalamu. M'mbuyomu, matenda okula ndi akuluakulu ndi masentimita 50 ndi pamwamba amadziwika.
Kuyambira kale chivwende chinapanga zinthu zambiri zomwe zimagwiritsidwa ntchito pa zakudya: kupanikizana, mapepala, zipatso zowonongeka. Kalekale mavwende osapsa ankagwiritsidwa ntchito monga zakudya zokoma.
Chifukwa cha zakudya zomwe zimakhala ndi mavitamini ndi kupambana kwakukulu zingagwiritsidwe ntchito mu zakudya za anthu omwe amatsogolera moyo wathanzi ndikugwira mwakhama chikhalidwe ndi masewera olimbitsa thupi. Kupezeka kwa fructose kumapangitsa minofu yogwira ntchito mosavuta. Zakudya zamagetsi zomwe zimakhala ndi chivwende, zothandiza pantchito ya ziwalo za magazi ndi mitsempha ya mtima, yomwe imalola thupi la munthu wophunzitsidwa kuti athetseretu kuvutika maganizo panthawi yophunzitsidwa. Chitsulo chomwe chimakhala mu madzi a chipatso ichi, chifukwa chakuti amatha kumanga maatomu a oksijeni mu hemoglobini, imakhala ndi mphamvu yogwiritsira ntchito minofu ya minofu.
Tsopano zikudziwika kuti zakudya za mavwende zimayambitsidwa ndi madzi okwanira (mpaka 80%), zinthu zamchere zamchere, chitsulo. Chakudya chochuluka cha chakudya chimenechi chili ndi calorie yochepa, yomwe ndi yofunika kwambiri kwa iwo amene akufuna kutaya mapaundi angapo owonjezera. Kukhalapo kwa zakudya zosavuta mosavuta m'chivwende kumagwiritsa ntchito zakudya zopatsa thanzi ngati matenda a chiwindi ndi kuledzera kwa thupi (zonse kunja ndi mkati). Pectin ndi fiber zimathandizanso kuti mavitamini azioneka m'matope, chifukwa kupezeka kwa mankhwalawa kumathandiza kuti ntchito ya m'mimba ikhale yovomerezeka.
Mavwende ali ndi chitsulo mu mawonekedwe a mtundu, zomwe zimapangitsa kukhala kosavuta kukumba izi. Akuti kudya kilogalamu imodzi ya mavwende kumatsimikizira kumeza kwa galamu imodzi ya chitsulo m'thupi la munthu. Chifukwa cha ichi, mavwende ndi ofunika kwambiri pa zakudya zokhudzana ndi zakudya za amayi apakati ndi amayi oyamwitsa, komanso pakukula kwa kuchepa kwachitsulo komanso kuchepa kwa magazi m'thupi. Kuwonjezera pa chitsulo, mavwende ali ndi zinthu zina zambiri zothandiza: calcium, sodium, magnesium, phosphorous.
Malo a chivwende choonjezera thupi kukaniza matenda opatsirana ndi chifukwa cha kukhala ndi mavitamini B 1 , B 2 , B 3 , PP, ascorbic ndi folic acid.
Chifukwa cha zakudya zothandizira, zipatso za mavwende zimalimbikitsidwa kugwiritsa ntchito matenda a atherosclerosis, matenda oopsa, nyamakazi, gout. Zakudya zapamwamba za fructose zimapangitsa kugwiritsa ntchito zipatsozi pang'onopang'ono mlingo wa shuga.
Ndi nephrolithiasis, nephritis ndi pyelonephritis, azamwali amalangiza kutenga 2 mpaka 2.5 kilogalamu ya mavwende pa tsiku. Zakudya za diuretic zamagetsi zimagwiritsidwa ntchito kuchotsa mchere m'thupi.
Komabe, pogwiritsa ntchito miyala, kuphatikizapo mpweya wa phosphate, kugwiritsa ntchito chivwende mu zakudya zopatsa thanzi sikoyenera.
Ma mkate a mavwende amakhalanso ndi katundu wothandiza. Makamaka, mu mawonekedwe awo owuma ndi owuma amagwiritsidwa ntchito pa zakudya zopatsa thanzi m'thupi. Mbewu ya mavwende inapeza ntchito monga hemostatic ndi antihelminthic.
