一.產品介紹

大米（Rice），是(shi)稻(dao)谷(gu)經清理(li)、礱谷(gu)、碾米、成(cheng)品整理(li)等工序后制成(cheng)的(de)成(cheng)品。 稻(dao)谷(gu)的(de)胚與糊粉層中含有近(jin)64%的(de)稻(dao)米營養(yang)和90%以上(shang)的(de)人體所須的(de)營養(yang)元素，是(shi)南方人民的(de)主(zhu)要食品。

大米的功效

1.嬰(ying)兒輔助飲食

有益于嬰兒的發育和(he)健康(kang)，能(neng)刺激(ji)胃液的分泌(mi)，有助于消化(hua)，并對脂肪的吸收(shou)有促(cu)(cu)進作用，亦能(neng)促(cu)(cu)使(shi)奶粉(fen)中的酪蛋白形成(cheng)疏松而又柔軟的小凝塊，使(shi)之容易消化(hua)吸收(shou)。

2.補充營養素的基礎食物

米粥具有補脾、和胃(wei)、清肺功效(xiao)。

營養價值

大(da)米(mi)(mi)(mi)中含(han)碳水(shui)化合(he)物(wu)75%左右，蛋(dan)(dan)白(bai)(bai)質(zhi)7%-8%，脂肪1.3%-1. 8%，并(bing)含(han)有豐富的(de)B族維生素等。大(da)米(mi)(mi)(mi)中的(de)碳水(shui)化合(he)物(wu)主要是(shi)淀粉(fen)，所含(han)的(de)蛋(dan)(dan)白(bai)(bai)質(zhi)主要是(shi)米(mi)(mi)(mi)谷(gu)蛋(dan)(dan)白(bai)(bai)，其次是(shi)米(mi)(mi)(mi)膠蛋(dan)(dan)白(bai)(bai)和球蛋(dan)(dan)白(bai)(bai)，其蛋(dan)(dan)白(bai)(bai)質(zhi)的(de)生物(wu)價和氨(an)基酸的(de)構成比(bi)例(li)都比(bi)小(xiao)麥、大(da)麥、小(xiao)米(mi)(mi)(mi)、玉米(mi)(mi)(mi)等禾谷(gu)類作(zuo)物(wu)高(gao)，消化率(lv)66.8%-83.1%，也是(shi)谷(gu)類蛋(dan)(dan)白(bai)(bai)質(zhi)中較高(gao)的(de)一種。

因(yin)此，食(shi)用(yong)大米(mi)有較(jiao)高的營養價值(zhi)。但大米(mi)蛋(dan)白質中(zhong)賴(lai)氨(an)酸和(he)蘇氨(an)酸的含量較(jiao)少，所以(yi)不是一種(zhong)完全蛋(dan)白質，其營養價值(zhi)比不上動物蛋(dan)白質。但在(zai)午餐(can)和(he)晚餐(can)時食(shi)用(yong)大米(mi)，較(jiao)面食(shi)而言更有利于(yu)人們(men)減肥。在(zai)我(wo)國南方地區(qu)人們(men)一般(ban)食(shi)用(yong)大米(mi)作(zuo)為主食(shi)，而在(zai)北方就有很大的不同。

脂(zhi)肪含量約9%，其脂(zhi)肪中(zhong)所含的亞油酸(suan)含量較高，一般占全部脂(zhi)肪的34%，比菜籽油和茶油分別多2-5倍。

禾（小米）、稻(dao)、稷（高粱）、麥(mai)、菽（豆）稱為“五谷”。（稻(dao)即(ji)是未加(jia)工(gong)的大米）。

食物搭配相宜

【大米+栗子】 兩(liang)者(zhe)均有(you)健脾養胃、壯筋骨之效(xiao)，結合時養胃補腎效(xiao)果(guo)極佳。

【大米(mi)+菠菜】 大米(mi)益氣健脾通血(xue)脈，菠菜滋陰補血(xue)二者搭配潤燥養血(xue)功效明顯(xian)。

【大米+山藥】 大米可平和五(wu)臟，山藥健(jian)脾補腎，二者搭配健(jian)脾益胃，助消化(hua)。

【大(da)米+白蘿卜】止痰化咳，利膈止渴，消除腫脹(zhang)。

【大米+銀耳】兩者搭配，滋陰潤肺、生津功效(xiao)更強。

【大(da)米+燕窩】搭配可平和五臟更可滋(zi)陰(yin)補氣。

【大米(mi)(mi)+小米(mi)(mi)】兩者營養互(hu)補(bu)，搭配食用可提高營養價值(zhi)。其(qi)小米(mi)(mi)的營養價值(zhi)高于大米(mi)(mi)，若兩者配合，有很好的營養價值(zhi)。

功效

中醫認為(wei)(wei)大(da)米味甘性平，具有(you)補中益氣、健(jian)脾養胃、益精強志、和五臟、通血脈、聰耳明目止煩、止渴(ke)、止瀉的功效，稱譽為(wei)(wei)“五谷之首”，是中國的主要糧食作(zuo)物，約(yue)占(zhan)糧食作(zuo)物栽培面積的四分之一(yi)。世界(jie)上有(you)一(yi)半人口以大(da)米為(wei)(wei)主食。

大(da)米(mi)，入脾(pi)、胃、肺經，具有補中(zhong)益氣、滋陰(yin)潤肺、健(jian)脾(pi)和胃、除煩渴的(de)作用(yong)(yong)。古代養(yang)生家還倡導“晨起食(shi)粥(zhou)”以生津液(ye)(ye)，因(yin)此(ci)，因(yin)肺陰(yin)虧虛所(suo)致的(de)咳嗽(sou)、便秘患者(zhe)可(ke)早晚(wan)用(yong)(yong)大(da)米(mi)煮粥(zhou)服用(yong)(yong)。經常喝點大(da)米(mi)粥(zhou)有助(zhu)于津液(ye)(ye)的(de)生發，可(ke)在一定程度上緩解皮膚干(gan)燥等不適。煮粥(zhou)時(shi)若加點梨，中(zhong)醫養(yang)生效果(guo)更好。
