Ngenkathi ubuchwepheshe bezolimo bukhula, abantu bazinza ezindleleni zokulima ngokudla okwenziwe ngamathuba ezolimo ku-geography yabo. Geographic futhi Emasiko kuye kwaholela ukudalwa eziningi ukudla okuhlukahlukene futhi ubuciko Culinary, kuhlanganise nezinto eziningi zezithako, amakhambi, izinongo, amasu, futhi izitsha . Njengoba amasiko axubene ngamandla afana nokuhweba kwamazwe omhlaba kanye nokwenziwa komhlaba wonke, izithako sezitholakala kabanzi ngaphezu kwemvelaphi yazo yezwe namasiko, okwenza kube nokushintshaniswa kwamasiko nemikhuba yokudla ehlukahlukene. Namuhla, iningi lamandla okudla adingeka emphakathini owandayo womhlaba ahlinzekwa yimboni yezimboni yokudla, ekhiqiza ukudla ngezolimo olunzulu futhi ikusabalalise ngokusebenzisa izindlela eziyinkimbinkimbi zokulungisa ukudla kanye nokwabiwa kokudla .
