Pure Beta Carotene hmoov puas tuaj yeem hloov xim tawv nqaij? Kev Tshawb Fawb Tom Qab Golden Glow
Ntshiab beta carotene hmoovyog ib qho ntawm cov isomers ntawm carotene, teej tug mus rau tsev neeg carotenoid. Nws kuj yog ib qho precursor rau vitamin A thiab ib qho ntawm feem ntau ubiquitous thiab ruaj khov pigments nyob rau hauv cov xwm.
Txawm li cas los xij, cov lus nug ib txwm ua rau cov neeg siv khoom thiab cov kws tshaj lij kev muag khoom zoo ib yam: tuaj yeem nojntshiab beta carotene hmoovyeej hloov koj cov tawv nqaij xim? Cov lus teb yog yog-tab sis qhov kev hloov pauv no tsis yog pigmentation mus tas li; Nws yog ib qho kev hloov pauv ntawm lub cev phenomenon hu ua carotenemia.
1. Mechanism: Yuav ua li cas Beta Carotene Deposits nyob rau hauv daim tawv nqaij
Pure beta carotene hmoov yog ib tug precursor rau vitamin A nyob rau hauv lub cev. Nws tau tawg ua ob lub molecules ntawm vitamin A los ntawm cov enzymes hauv daim siab thiab cov hnyuv loj, yog li nws tseem hu ua provitamin A lossis previtamin A. Txij li thaum tib neeg lub cev xaiv faib -carotene molecules rau hauv ob los hloov lawv mus rau hauv vitamin A, kev noj ntau dhau ntawm -carotene yuav tsis ua rau hypervitamin A.
Raws li 2024 kev tshawb fawb luam tawm nyob rau hauv IEEE Xplore, beta carotene deposition nyob rau hauv daim tawv nqaij tshwm sim los ntawm ob tug thawj txoj kev: diffusion los ntawm cov ntshav thiab adipose ntaub so ntswg mus rau hauv daim tawv nqaij, thiab tso tawm mus rau ntawm daim tawv nqaij nto los ntawm hws thiab sebaceous qog tom qab nkag mus rau hauv lub stratum corneum.
Deposited beta carotene feem ntau yog muab faib rau hauv stratum corneum, epidermis, thiab dermis. Hauv cov tib neeg uas muaj cov tawv nqaij sib zog, vim cov ntsiab lus melanin qis dua, beta carotene qhov nqus ntawm lub teeb pom kev pom tseeb dua, ua rau muaj cov yam ntxwv yellowish tint - feem ntau pom thawj zaug ntawm cov xib teg thiab cov leeg.
2. Cov ntaub ntawv pov thawj kho mob: Cov kev tshawb fawb qhia dab tsi
2.1 Dose Thresholds
Raws li Cleveland Clinic dermatologists, noj txhua hnub ntawm 20-50 mg ntawm beta carotene rau ob peb lub lis piam yog txaus los ua kom pom cov xim ntawm daim tawv nqaij. Rau cov ntsiab lus, ib qho zaub ntug hauv paus nruab nrab muaj kwv yees li 4 mg ntawm beta carotene-lub ntsiab lus noj 10 carrots txhua hnub rau lub lis piam tuaj yeem ua rau muaj txiaj ntsig zoo.
2.2 Kev soj ntsuam kuaj pom tseeb
Ib xyoo 2013-2014 ib leeg- qhov muag tsis pom kev hla kev sib tw muab pov thawj txaus. Peb caug tus poj niam tau raug xa mus rau qhov siab - noj zaub mov carotenoid (176,425 ug beta carotene txhua lub lim tiam) lossis qis-carotenoid noj rau 4 lub lis piam.
Cov txiaj ntsig tau pom qhov siab - pab pawg noj zaub mov pom tau tias muaj kev nce ntxiv hauv cov tawv nqaij daj ntawm ob lub hnub- raug thiab tsis yog - qhov chaw raug (p<0.001). Skin yellowness correlated positively with blood beta carotene levels.
2.3 Antioxidant cuam tshuam rau Pigmentation
Ib xyoo 1997 randomized ob - qhov muag tsis pom kev tshawb fawb pom tias kev noj tshuaj txhua hnub nrog 13 mg beta carotene (sib txuas nrog lwm cov tshuaj antioxidants) rau 8 lub lis piam tsis tsuas yog ua rau pom carotenemia, tab sis kuj nce melanin concentration hauv daim tawv nqaij (p<0.05). Researchers suggested this may relate to antioxidants modulating melanocyte activity.
3. Kev nthuav qhia kho mob: Qhov twg thiab yuav ua li cas
Carotenemia nthuav tawm tus yam ntxwv qauv:
Qhov chaw pib: Xibtes, cov khauj khaum, nasolabial quav, thiab lub qhov ntswg qhia txiv kab ntxwv - daj daj thaum ntxov
Cov qauv sib kis: Maj mam txuas mus rau tag nrho lub cev nrog kev noj ntau ntxiv
Qhov txawv ntawm qhov tseem ceeb: Cov sclera (qhov muag dawb) thiab cov mucous daim nyias nyias nyob twj ywm tsis muaj kev cuam tshuam - qhov no cuam tshuam qhov sib txawv ntawm carotenemia los ntawm jaundice
Nyob rau hauv cov tawv nqaij sib zog, xibtes thiab ib leeg yellowing yog pom tseeb; Nyob rau hauv cov tawv nqaij tsaus, nws yuav manifest li xibtes yellowing nrog maj mam brightening lwm qhov chaw.
4. Kev nyab xeeb: thim rov qab thiab zoo
4.1 Ua kom tiav Reversibility
Cov tawv nqaij hloov induced los ntawmntshiab beta carotene hmoovyog reversible kiag li. Tom qab txo lossis txiav kom tsis txhob noj, cov xim ntawm daim tawv nqaij rov zoo li qub nyob rau ob peb lub lis piam mus rau lub hlis raws li cov ntaub so ntswg tshem tawm.
4.2 Qhov tseem ceeb sib txawv ntawm Jaundice
Yog tias qhov muag dawb tshwm daj, kev tshuaj xyuas tam sim rau kab mob siab yog tsim nyog - qhov no yeej tsis tshwm sim nrog carotenemia.
4.3 Cov neeg tshwj xeeb
Cov neeg mob hypothyroid: Tej zaum yuav muaj kev hloov pauv vitamin A tsis zoo, ua rau muaj carotenemia
Cov neeg mob ntshav qab zib, cov neeg mob siab / raum: tuaj yeem tsim cov carotenemia thib ob
Cov neeg haus luam yeeb: siab- noj tshuaj beta carotene ntxiv (20-30 mg/hnub) tau cuam tshuam nrog kev pheej hmoo mob qog noj ntshav hauv cov neeg haus luam yeeb-qhov ceeb toom kev nyab xeeb tseem ceeb
5. Tshaj xim: Cov txiaj ntsig tiv thaiv tawv nqaij
5.1 Kev tiv thaiv kev tiv thaiv
Carotenoids txhim kho daim tawv nqaij lub ntuj tiv thaiv UV-induced erythema (sunburn) thiab muab kev tiv thaiv UVA-induced pigmentation thaum inhibiting oxidative stress markers.
5.2 Los tiv thaiv-Cov teebmeem Kev laus
Beta carotene nthuav tawm lub zog singlet oxygen quenching peev, tiv thaiv cov qauv ntawm daim tawv nqaij los ntawm UV-induced lipid oxidation thiab collagen puas.
5.3 Isomer Matters
Ib txoj kev tshawb fawb 2023 Food Chemistry pom Z-isomer-enriched beta carotene qhia tau tias zoo dua UV-shielding, anti-elastase, thiab anti-melanogenesis kev ua piv rau cov pa txhua yam -E-isomers{8} tom ntej {8} cov khoom xyaw.
