Shuga yoyamba, inayamba kulandiridwa kwa zaka zikwi zingapo zisanafike nthawi yathu, ku India. Anapangidwa ndi nzimbe. Kwa nthawi yaitali, anali shuga wokha umene amadziwika ndi anthu. Mpaka pano, mu 1747 katswiri wa zamalonda wa ku Germany, Andreas Sigismund Marggrave, sananene kuti angathe kutenga shuga kuchokera ku beetroot pamsonkhano wa Prussian Academy of Sciences. Komabe, kupanga mafakitale a shuga a beet kunayamba mu 1801, ndipo izi zinali zosandulika m'makampani ogulitsa. Kuyambira nthawi imeneyo, shuga yakhala yowonjezereka, maswiti kuchokera ku zakudya zosazolowereka zomwe zadutsa pang'onopang'ono zidutsa m'gulu la chakudya cha tsiku ndi tsiku. Zipatso zomvetsa chisoni za izi zimadziwika bwino kwa tonsefe - matenda a mano ndi kunenepa kwambiri zakhala vuto lenileni m'masiku ano.
Kodi shuga ndi chiyani?
Shuga ali pafupifupi mawonekedwe ake a sugarro-carbohydrate, omwe thupi lathu limagawanika mu shuga ndi fructose ndipo amatanthauza "zakudya" mwamsanga. Glycemic index ya shuga ndi 100. Shuga ndi mphamvu yoyera, osati kuvulaza, kapena kupindula, motere, siimakhala nayo yokha. Mavuto amayamba pamene timapeza mphamvu zambiri kuposa momwe tingathere. Taganizirani zomwe zimachitika pamene shuga imalowa m'thupi lathu. Kutukira kwa sucrose kumachitika m'mimba mwazing'ono, kumene monosaccharides (shuga ndi fructose) zimalowa m'magazi. Kenaka chiwindi, chomwe shuga imatumizidwa ku glycogen - malo osungira mphamvu pa "tsiku lamvula", lomwe limasinthidwanso mosavuta, limatengedwa kuti liwonekere. Ngati, kuchuluka kwa shuga kupitirira chofunika chokwanira, chomwe chingasandulike kukhala glycogen, ndiye kuti insulini imayamba kugwira ntchito, kusamutsa shuga ku malo ogulitsa mafuta. Ndipo kukhala ndi mafuta, thupi lathu ngati silikukonda, kuchokera apa - kulemera kwakukulu, kuperewera. Kuonjezerapo, ngati pali shuga wochuluka kuchokera ku chakudya, ndiye kuti mphamvu za maselo ndi insulini zimachepa, mwachitsanzo, sangathe kuyendetsa glucose mopitirira muyeso, zomwe zimayambitsa kuwonjezeka kwa shuga m'magazi, ndipo zotsatira zake zingayambitse mtundu wa shuga.
Koma kusowa kwa zakudya ndizovulaza. Zamoyo zimayenera kutenga mphamvu kuchokera kwinakwake. Choncho, ndibwino, mwinamwake, kuti musalankhule za kuvulaza kapena kupindula ndi shuga, motere, koma moyenera.
Zipatso shuga - zabwino ndi zoipa
Zipatso shuga, kapena fructose - ndi wachibale wamkati wa shuga, koma mosiyana ndi iyo, safuna insulini kuti igwiritsidwe ntchito, kotero ingagwiritsidwe ntchito kwa odwala matenda a shuga. Komabe, ngakhale kuti fructose ikhoza kupangidwanso kukhala mafuta, sizimapangitsa kuti thupi likhale lopweteketsa, kotero likhoza kuthandizira kukula kwa kunenepa kwambiri. Lili ndi fructose, osati kokha shuga, koma mu zipatso zambiri, chifukwa chake, ndi dzina lake.
Shuga ya mphesa ndi yabwino komanso yoipa
Shuga yamphesa amatchedwa shuga. Izi ndizimene zimapangitsa kuti thupi liziyenda bwino. Ubwino ndi kuwonongeka kwa shuga wamphesa zimasiyana pang'ono ndi shuga wamba. Kuvulazidwa kumayambitsidwa ndi kuthekera kwa njira zowonongeka ndi zowonjezera, zomwe zingasokoneze microflora.
Mankhwalawa shuga ndi abwino komanso oipa
Shuga yoyamba imadziwika kwa anthu. Amachokera ku nzimbe. M'mawonekedwe ake, pafupifupi ofanana ndi beet shuga ndipo ali ndi 99% peresenti sucrose. Mitundu ya shuga yoteroyo ndi yofanana ndi yomwe imayenderana ndi tizilombo toyambitsa matenda.
Shuga yamapiri ndi yabwino komanso yoipa
Amapezeka poumitsa madzi a tsiku, kokonati kapena kanjedza ya shuga. Ndi mankhwala osagwiritsidwa ntchito, motero amaonedwa ngati njira yathanzi ya shuga. Tikayerekezera shuga ndi zinyama zina, ndiye kuti tinganene kuti zilibe vuto lililonse.
