假如您有逛健康食品店的習慣,您一定會留意到來自南美的食物近年大行其道。原產於南美洲安第斯山區的藜麥,目前是有機健康的熱門產品,很多對小麥過敏或追求營養的人士都會選購。而另一種是瑪卡,原產於南美洲安第斯山區,傳說印加人的軍隊就靠著瑪卡補充能量,並建立了空前絕後的印加大帝國。因著這種增加體力、增強耐力以及抵抗疲勞的力量,瑪卡在歐美及中國都非常流行。最近我們發現一種更新穎的南美食物。

菊薯(Yacon) – 這個名詞有點陌生,它原產自南美洲海拔1000米以上的安第斯山脈,是當地印第安人的一種傳統根莖食品。菊薯又名雪蓮果,在南美「神果」的意思。在健康商店看到,通常是菊薯製成的果乾或糖漿,可以當零食吃,吃的時候會覺得它甜甜的,有點像蘋果片的味道,口感如其他水果乾一樣,是一種既美味又含豐富營養價值的植物。菊薯含有菊糖,菊糖是一種很難消化的醣類,這意味著它吃起來雖然很甜,可是它所含的卡路里卻是非常低。

日本研究發現,這種植物有藥理作用,能有效控制膽固醇和糖尿病。若以雪蓮果葉加工成葉飲用,更會有降血糖的作用,而且對消化道、循環消化系統及結腸癌都有一定的治療作用。在香港,街市菜販一般稱之為雪蓮果,一般用來煲老火湯,可是果寡糖會因受熱而減低其作用,這樣就浪費了它不少營養。

菊薯亦有多種對人類健康的優點,其中包括﹕

1. 預防便秘
菊薯能刺激腸內蠕動,促進益菌生長及抑制壞菌生長,還有提高整腸的作用。

2. 糖尿病 – 抑制血糖值上升
菊薯內含有的大量果寡糖,就是它的甜味。果寡糖是糖尿病患者理想的純天然植物代糖,飲用菊薯葉泡製而成的飲料能抑制血糖值上升。亦有相關研究顯示,果寡糖可降低糖尿病患的高血糖,並同時降低過高的膽固醇含量。

3. 瘦身和抗氧化作用
菊薯含低卡路里並含豐富營養素。有相關研究顯示,進食菊薯有飽肚作用,瘦身中的人會變相在進食正餐時份量減少。它的葉子亦有利尿作用,促進身體的新陳代謝,對於節食有需求的人是很好的東西。

進食適量菊薯能對人體健康有益,可是即使菊薯含有豐富的營養及多種對人類健康的功效,亦都不能把它當主食及過量進食。市面上有些地方售賣的有機菊薯乾是標明無麩質及素食食品,因此如對小麥過敏的您,又多了一款有益健康的零食選擇了!
