Noi cercet\u0103ri sugereaz\u0103 c\u0103 oamenii au pr\u0103jit \u0219i consumat r\u0103d\u0103cinoase timp de cel pu\u021bin 170.000 de ani, contest\u00e2nd interpret\u0103rile moderne ale \u201edietei paleo\u201d.<\/p>\n\n
\u00centr-un studiu publicat \u00een revista Science, cercet\u0103torii au descoperit r\u0103m\u0103\u0219i\u021be carbonizate de materie vegetal\u0103 bogat\u0103 \u00een carbohidra\u021bi \u00eentr-o pe\u0219ter\u0103 din Africa de Sud. Aceste r\u0103m\u0103\u0219i\u021be carbonizate, identificate ca rizomi sau tulpini subterane, ofer\u0103 cele mai vechi dovezi ale faptului c\u0103 oamenii g\u0103teau \u0219i consumau \u00een mod deliberat plante bogate \u00een amidon.<\/p>\n\n
\u00cen ciuda presupunerilor moderne despre dieta paleo, care pune accentul pe un aport sc\u0103zut de carbohidra\u021bi, studiul sugereaz\u0103 c\u0103 str\u0103mo\u0219ii no\u0219tri preistorici consumau probabil o diet\u0103 echilibrat\u0103, care includea at\u00e2t carbohidra\u021bi, c\u00e2t \u0219i proteine.<\/p>\n\n
Rizomii, care se g\u0103sesc \u00een plante precum cartofii \u0219i ignamele, sunt boga\u021bi \u00een proteine \u0219i amidon. Atunci c\u00e2nd sunt prepara\u021bi \u0219i consuma\u021bi, ace\u0219tia ofer\u0103 un aport nutritiv semnificativ.<\/p>\n\n
Consumul de plante bogate \u00een amidon de c\u0103tre oameni a coincis probabil cu o cre\u0219tere a expresiei genelor care faciliteaz\u0103 digestia amidonului, indic\u00e2nd o schimbare a dietei c\u0103tre o diet\u0103 mai bogat\u0103 \u00een carbohidra\u021bi \u00een urm\u0103 cu peste 300.000 de ani.<\/p>\n\n
Tratarea termic\u0103 a alimentelor, inclusiv a r\u0103d\u0103cinoaselor, are numeroase beneficii. \u00cenmoaie alimentele, f\u0103c\u00e2ndu-le mai u\u0219or de mestecat \u0219i digerat, \u0219i \u00eembun\u0103t\u0103\u021be\u0219te extragerea nutrien\u021bilor.<\/p>\n\n
Utilizarea focului pentru pr\u0103jirea legumelor nu numai c\u0103 le-a \u00eembun\u0103t\u0103\u021bit valoarea nutritiv\u0103, dar le-a f\u0103cut \u0219i mai u\u0219or de g\u0103sit pentru arheologii moderni, spre deosebire de oasele de animale care se descompun mai u\u0219or.<\/p>\n\n
Descoperirea plantelor bogate \u00een amidon g\u0103tite de acum 170.000 de ani sugereaz\u0103 c\u0103 dieta paleo, a\u0219a cum este adesea interpretat\u0103 ast\u0103zi, poate fi un termen impropriu. Str\u0103mo\u0219ii no\u0219tri preistorici au m\u00e2ncat probabil mai multe plante bogate \u00een amidon dec\u00e2t se presupunea anterior.<\/p>\n\n
Tranzi\u021bia la g\u0103tit, \u00een special a r\u0103d\u0103cinoaselor, a fost un reper semnificativ \u00een evolu\u021bia uman\u0103. A permis consumul unei game mai largi de alimente vegetale, a furnizat substan\u021be nutritive esen\u021biale \u0219i a facilitat dezvoltarea unor comportamente sociale \u0219i culturale mai complexe.<\/p>\n\n
Descoperirea plantelor bogate \u00een amidon g\u0103tite de acum 170.000 de ani deschide noi c\u0103i pentru cercetarea practicilor alimentare umane \u0219i a evolu\u021biei g\u0103titului. Excav\u0103rile \u0219i analizele ulterioare ale siturilor arheologice ar putea face lumin\u0103 asupra plantelor specifice consumate de str\u0103mo\u0219ii no\u0219tri \u0219i rolului g\u0103titului \u00een modelarea istoriei umane.<\/p>","protected":false},"excerpt":{"rendered":"
