Kudya mavwende okhwima komanso okhwima opanda nitrates ali ndi zoopsa zake. Watermelon ndi chakudya chokoma komanso chotsitsimula chokhala ndi ma calories ochepa m'chilimwe. Amapereka hydration komanso amapereka zakudya zofunika, kuphatikizapo mavitamini, mchere, ndi antioxidants.
Pamodzi ndi vwende, uchi, ndi nkhaka, mavwende ndi a banja la dzungu. Pali mitundu isanu yodziwika bwino ya mavwende: seeded, seedless, mini, yellow, orange.
M'nkhaniyi, muphunzira zambiri za ubwino ndi thanzi la chivwende, komanso malangizo ogwiritsira ntchito komanso kuopsa kwa chivwende. Choyamba, pali zoopsa kudya ngakhale kucha osati mavwende oyambirira popanda nitrate.
Kuopsa kwake
Chifukwa chiyani chivwende ndi chowopsa? Chivwende chochuluka sichiika pachiwopsezo chachikulu cha thanzi kwa anthu ambiri, koma ena angafunikire kusamala.
Matenda a shuga: Chivwende ndi chipatso chokhala ndi shuga wachilengedwe. Anthu odwala matenda a shuga ayenera kuganizira za chakudya cham'mawa pazakudya zawo za tsiku ndi tsiku. Ndi bwino kudya chivwende chonse m'malo mwa madzi, chifukwa madziwo amachotsa fiber, zomwe zimapangitsa kuti thupi lizitha kuyamwa shuga. Izi zitha kukulitsa chiwopsezo cha kuchuluka kwa glucose. Kumbukirani kuwonera kukula kwa magawo, monga zipatso zonse ndi timadziti.
Zilonda: Anthu ena amatha kukhala ndi zizindikiro za ziwengo, monga ming'oma, kutupa, ndi kupuma movutikira, akadya chivwende. Izi zikachitika, munthuyo amafunikira chithandizo chamankhwala, chifukwa nthawi zina zimatha kuyambitsa anaphylaxis, yomwe ndi vuto loyika moyo pachiswe.
Chifukwa chiyani mavwende oyambirira ali owopsa?
Aliyense amadziwa kuti mavwende amacha kumwera kwa dzuwa kumapeto kwa chilimwe. Panthawiyi, mtengowo ndi wotsika, womwe sugwirizana ndi ogulitsa. Pokhala woyamba kuyika malonda pamsika, amatha kupeza zambiri. Choncho, ogulitsa amayenera kudyetsa zomera ndi nitrates. Chifukwa cha chemistry, kukula kwa mavwende kumafulumizitsa. Amatha kukolola mu June-Julayi pamene mpikisano akugwira ntchito pa vwende.
Mavwende ambiri amalimidwa m’minda osati m’malo obiriwira. Zomera zazing'ono zimafuna kutentha. Komabe, amakhala amphamvu pamene amapeza misa yobiriwira. Kuti mbewu zisamatenthedwe, alimi amathira feteleza wambiri. Nthawi zambiri, feteleza wa nayitrogeni-phosphorous amagwiritsidwa ntchito. Amathandizira kuti nthaka ikhale yachonde komanso imathandizira kuti mavwende ayambe kucha.
Ndicho chifukwa chake mavwende oyambirira amatha kukhala ndi zinthu zambiri zoopsa chifukwa chogwiritsa ntchito feteleza mopitirira muyeso. Sangalawe. Kamodzi m'mimba, nitrate imasandulika kukhala nitrites, zomwe zimawopseza hemoglobin. Kuphatikiza ndi maselo a magazi, amawasandutsa kukhala methemoglobin. Pang'ono ndi pang'ono, njala ya okosijeni imayamba m'thupi, zomwe zimachititsa kuti thanzi liwonongeke.
Mukamadya mavwende "odyetsedwa" ndi nitrates, poizoni amapezeka nthawi zambiri. Zizindikiro zimawonekera nthawi zambiri maola 2-3 mutadya mankhwalawa. Zinthu zovulaza zimalowetsedwa kwathunthu m'magazi kwa nthawi yayitali, choncho chithandizo chachikulu chimafunika.
Ngati simupita kuchipatala panthawi yake ndikunyalanyaza zizindikiro zoopsa za poizoni, mukhoza kufa chifukwa cha kuledzera kwambiri komanso kutaya madzi m'thupi. Ana amakhudzidwa kwambiri ndi zinthu zoterezi. Choncho, kudya mavwende mu June ndi July si lingaliro labwino.
Momwe mungayang'anire mavwende ngati ali ndi nitrate kunyumba
Kuti muwone mavwende a nitrate kunyumba, ndikwanira kudula kachidutswa kakang'ono ka "mabulosi" ndikuphwanya pang'ono mu kapu yamadzi osungunuka (kapena madzi wamba owiritsa). Pamaso pa nitrate, madziwo amakhala ofiira.
Ubwino wa chivwende
Madzi omwe ali muvwende angathandize munthu kuti asatayike m'thupi. Chivwende chili ndi madzi pafupifupi 90%, zomwe zimapangitsa kuti m'nyengo yachilimwe zikhale zothandiza kupewa kutaya madzi m'thupi. Ikhozanso kukhutiritsa dzino lotsekemera ndi shuga wake wachilengedwe.
Watermelon alinso ndi antioxidants. Zinthuzi zingathandize kuchotsa mamolekyu omwe amadziwika kuti ma free radicals kapena zinthu zomwe zimagwira ntchito m'thupi. Thupi limapanga ma free radicals panthawi yachilengedwe monga metabolism. Angathenso kukula kuchokera ku kusuta, kuwononga mpweya, kupsinjika maganizo, ndi zinthu zina zachilengedwe.
Ngati ma free radicals ambiri amakhalabe m'thupi, kupsinjika kwa okosijeni kumatha kuchitika. Izi zingayambitse kuwonongeka kwa maselo ndi matenda angapo, monga khansa ndi matenda a mtima.
Thupi limatha kuchotsa ma free radicals mwachilengedwe, koma ma antioxidants amathandizira izi. Pansipa pali njira zina zomwe ma antioxidants ndi zakudya zina zomwe zimapezeka muvwende zingathandizire kuteteza thanzi la munthu.
Pewani mphumu
Akatswiri ena amakhulupirira kuti ma free radicals amathandizira pakukula kwa mphumu. Kukhalapo kwa ma antioxidants ena m'mapapu, kuphatikizapo vitamini C, kungachepetse chiopsezo cha mphumu.
Kafukufuku sanatsimikizire kuti kumwa mankhwala owonjezera a vitamini C kungathandize kupewa mphumu, koma zakudya zokhala ndi vitamini C zimatha kupereka chitetezo. Kapu ya mipira ya chivwende yolemera pafupifupi magalamu 154 (g) imapereka 12.5 milligrams (mg) ya vitamini C kapena 14% mpaka 16% ya magwero odalirika a munthu tsiku lililonse.
Kuthamanga kwa magazi
Mu kafukufuku wa 2012, ofufuza adapeza kuti chotsitsa cha chivwende chimachepetsa kuthamanga kwa magazi mkati ndi kuzungulira akakolo mwa anthu azaka zapakati onenepa omwe ali ndi matenda oopsa kwambiri. Olembawo adanenanso kuti L-citrulline ndi L-arginine, ma antioxidants awiri mu chivwende, amatha kusintha ntchito ya arterial.
Lycopene, antioxidant wina mu chivwende, angathandize kuteteza matenda a mtima. Ndemanga mu 2017 inanena kuti izi zikhoza kuchitika mwa kuchepetsa kutupa komwe kumayenderana ndi high-density lipoprotein (HDL) kapena cholesterol "yabwino".
Phytosterols ndi mankhwala a zomera omwe angathandize kuthana ndi otsika kachulukidwe lipoprotein (LDL) kapena "zoipa" cholesterol. Malangizo ena amalimbikitsa kudya 2 magalamu (g) a phytosterols tsiku lililonse. 154 g ya mipira ya chivwende imapereka pang'ono - 3.08 mg.
Kuchepetsa LDL cholesterol kungathandize kupewa kuthamanga kwa magazi ndi matenda a mtima (CVD), koma zotsatira zenizeni za phytosterols pa CVD sizidziwika.
Cancer
Nyuzipepala ya National Cancer Institute (NCI) inanena kuti ma radicals aulere angathandize pakukula kwa mitundu ina ya khansa. Kupsinjika kwa okosijeni komwe amayambitsa kungayambitse kuwonongeka kwa DNA m'maselo.
Zakudya za antioxidant zomwe zimapezeka muvwende, monga vitamini C, zimatha kuteteza khansa polimbana ndi ma free radicals. Kafukufuku wina adagwirizanitsanso kumwa lycopene ndi chiopsezo chochepa cha khansa ya prostate.
Kugaya chakudya ndi kukhazikika
Chivwende chimakhala ndi madzi ambiri komanso chimakhala ndi fiber. Zakudya izi zimathandiza kuti matumbo azikhala ndi thanzi labwino popewa kudzimbidwa komanso kulimbikitsa kuyenda kwamatumbo nthawi zonse.
Kuthamanga
Chivwende ndi madzi 90% komanso chimakhala ndi ma electrolyte monga potaziyamu. Izi zimapangitsa kukhala chakudya chopatsa thanzi m'miyezi yotentha yachilimwe.
Anthu amatha kudya chivwende chatsopano, chamadzimadzi, kapena zidutswa zachisanu kuti adye chakudya chokoma chamtundu wa popsicle.
