「煮豆燃豆萁,豆在釜中泣;本是同根生,相煎何太急!」相傳呢首為曹植所寫,以豆為主題嘅七步詩,喺最緊急嘅時刻,救咗佢一命。喺呢件流傳萬世嘅史事當中,我哋除咗可以睇到曹植嘅急智同才華,同時間亦可以睇到豆(bean)喺我哋飲食文化同日常生活上所扮演嘅重要角色,小「豆」丁嘅力量真係不容忽視!
世界上大概有40,000種嘅豆1,2,分佈世界各地,當中有約十多廿個不同科屬,被不同民族用作日常食用嘅豆。呢啲被揀作食糧嘅豆,大多數都含有植物性蛋白質、碳水化合物、纖維、多種維生素及礦物質(如鉀及鋅)等3。可以提供咁多維持健康嘅元素,呢啲細細粒嘅小「豆」丁,當然被視為「養命」嘅好東西。但小「豆」丁嘅力量,又點會得咁少?!今日就等我喺呢度介紹幾位「救命」嘅小「豆」丁:
(1)黑龜豆(Black turtle bean),學名Phaseolus vulgaris ‘Black turtle’,有時我哋都會喺雜菜湯中食到,早已確實有助對抗細胞變異4,並且科學家喺2017年更加發現,佢對乳癌患者有幫助5。
(2)綠豆(Mung bean),學名為Vigna radiata,就係我哋用嚟煲綠豆沙嘅主角,佢除咗我哋耳熟能詳嘅清熱功能,科學家更發現到原來佢亦可以幫手處理肝硬化及脂肪肝嘅問題6,真係估佢唔到!
(3)毛豆/枝豆(Vegetable soybean / Edamame bean),學名為Glycine max merr.。唔好以為佢只係日本料理中嘅美味餐前小食,其實佢對處理血糖血脂亦有一手7。
今日就同大家介紹住咁多先,有機會再同大家介紹其他小「豆」丁英雄。
