Cov khoom ntuj muaj nyob hauv txiv kab ntxwv, kua txob liab thiab ntau yam "xim" txiv hmab txiv ntoo thiab zaub tuaj yeem tiv thaiv kab mob ntsws. Nyob rau hauv cov nplooj ntawv ntawm ib phau ntawv kho mob nrov, cov kws sau ntawv ntawm txoj kev tshawb fawb tshiab tau thov cov txiaj ntsig prophylactic ntawm beta-cryptoxanthin. Cov tshuaj no nyob rau hauv cov txiv hmab txiv ntoo thiab zaub muaj yeeb yuj suppresses receptors uas nicotine fuels kev loj hlob ntawm malignant qog. Co-sau ntawm txoj kev tshawb no Hiang-Dong Wong los ntawm Tufts University hauv Boston paub tseeb tias cov txiaj ntsig tau tuaj yeem txo qis qhov tshwm sim ntawm mob ntsws cancer thoob ntiaj teb.

Raws li American Lung Association, cov txiv neej haus luam yeeb tuag ntawm mob ntsws cancer 23 npaug ntau dua li cov neeg tsis haus luam yeeb. Kev haus luam yeeb Passive kuj tseem muaj feem ntau hauv qhov kev txheeb xyuas no. Txhua xyoo hauv Asmeskas, kwv yees li 7,000 tus neeg tuag los ntawm mob qog noj ntshav los ntawm cov pa luam yeeb.

Ntau tshaj 7,000 chemicals tau pom nyob rau hauv cov pa luam yeeb, ntau yam uas yog carcinogenic, i.e. tuaj yeem ua rau mob ntsws cancer yog tias nqus tau. Txawm hais tias alkaloid nicotine tsis ntseeg tias yog qhov ua rau mob qog noj ntshav tam sim ntawd, qee cov kws tshawb fawb tau pom tias nws muaj kev cuam tshuam ncaj qha rau kev loj hlob ntawm cov qog nqaij hlav malignant. Dr. Wong piav qhia tias thaum nicotine nkag mus rau hauv lub ntsws, lub npe hu ua nicotinic acetylcholine receptors. Ib qho cascade ntawm cov tshuaj tiv thaiv cellular tshwm sim, ua rau kev loj hlob thiab kev loj hlob ntawm cov hlab ntsha tshiab, i.e. txoj hauv kev tshiab los muab cov khoom noj rau mob qog noj ntshav. Qhov no yog raws nraim li cov qog uas tsis tuaj yeem loj hlob xav tau. Tsis tas li ntawd, nicotine txhawb kev tsim cov receptors tshiab thiab tshiab, vim tias cov qog tau txais kev noj haus ntau dua. Raws li tus kws tshaj lij, beta-cryptoxanthin txo cov pej xeem ntawm cov receptors hauv lub ntsws thiab yog li tiv thaiv kev loj hlob ntawm cov hlwb tsis zoo.

Tus cawm seej no beta-cryptoxanthin yog qhov tseem ceeb ntawm carotenoid uas muab cov txiv hmab txiv ntoo thiab zaub ci daj, txiv kab ntxwv thiab xim liab. Xws li apricots, txiv kab ntxwv, tangerines, kua txob liab, thiab lwm yam. Hauv lawv cov kev tshawb fawb yav dhau los, cov kws tshawb fawb Boston tau pom qhov sib txuas ntawm kev siv beta-cryptoxanthin thiab qhov tshwm sim ntawm mob ntsws cancer hauv tib neeg. Thiab tam sim no lawv tau txiav txim siab los qhia meej txog cov txheej txheem ntawm kev tiv thaiv ntawm cov carotenoid no siv cov nas kuaj.

Cov txiaj ntsig tau qhia: cov qog ntawm cov nas muab beta-cryptoxanthin loj hlob 60% qeeb dua. Txheeb xyuas qhov tsim nyog ntawm cov tshuaj no rau cov neeg haus luam yeeb txhawm rau tiv thaiv kev mob qog noj ntshav, lawv tuaj yeem txiav txim siab tias nws txaus rau lawv noj 870 mg ntawm beta-cryptoxanthin ib hnub. Raws nraim qhov no muaj nyob rau hauv ib lub kua txob liab los yog ob tangerines. Koj pom tias nws yuav siv sij hawm tsawg npaum li cas los tiv thaiv tus kab mob insidious no - tshwj xeeb tshaj yog tias koj yog tus neeg haus luam yeeb.
