Amavithamini kufanele alawulwe nsuku zonke ukuze asebenze ngokujwayelekile. Zingatholakala emikhiqizweni yokudla nasezidakamizweni ezakhiwe ema laboratories.
Ingabe amavithamini zokwenziwa asebenzayo?
Izingxabano zalesi sihloko aziyekanga iminyaka eminingi. Abanye ochwepheshe bathi "i-chemistry" ayikwazi ukuwusizo emzimbeni, kanti abanye bakholelwa okuphambene nalokho. Kunombono wokuthi amavithamini okufakelwa, ahlanjululwe ngokujulile, asebenza kahle futhi angcono kakhulu emzimbeni. Izinzuzo zihlanganisa iqiniso lokuthi yonke imithombo ekhona yokungalingani isuswe ngokuphelele kumuthi.
Kubantu abaningi, ulwazi mayelana nezinzuzo kanye nokulimaza kwamavithamini zokwenziwa akukaziwa. Ukungazi okunjalo kungaholela ezinkingeni ezinkulu, njengoba ukuhlolwa kwamuva kwenziwa imiphumela emangalisayo - ukusetshenziswa okunamandla kwamavithamini wokwenziwa kuyingozi futhi kwenza kube lula ukunciphisa ukuphila, lokhu akusebenzi emvelweni. Izinto zokwenza izinto ezinokusetshenziswa isikhathi eside ziholela ekutheni umzimba uyeka ngaphandle kosizo ukulwa nama-virus kanye nezifo. Ukusetshenziswa ngokweqile kwe-vitamin A kubangela ukuthuthukiswa kwezifo zesibindi kanye nezinsizi. Inani elikhulu levithamini D lingabangela izinkinga zezinso nezinhliziyo, futhi ukwedlula uvithamini E kunomthelela omubi ngesisu futhi kuholela ekusizini. Ngokuvamile, amavithamini wokwenziwa angadliwa, kodwa awanikeze kuphela futhi anikeze umthamo kufanele udokotela.
Umehluko phakathi kwamavithamini wokwenziwa komzimba nemvelo ngenxa yokuthi, njengokuthi, "okude" futhi imvelo ingawabona kuphela ngosizo lwezinye izinto. Amanye amavithamini akalokwanga noma agciniwe, noma aphethwe ngokwemvelo. Abantu abaningi banesithakazelo sokuthi bahlukanise kanjani amavithamini ezakhiwe ezivela emvelo ngaphandle kokuhlolwa kwama laboratory? Kukhona indlela yokuphuma - bheka ukubheka futhi uma izinto zingezona izinto ezingokwemvelo, khona-ke kuzoboniswa ukuthi isidakamizwa kufanele "sithathwe yizifundo" noma "senze ama-breaks wenyanga".
