燕窝与亚硝酸盐

燕窝是华人传统营养价值高,而且被视为养颜补身的极品。可是近来由于价格高企,商家为了赚快钱,纷纷出现问题。其中亚硝酸盐更加被发现严重超标。

燕窩是中國自明代以來開始被食用的傳統名貴食品之一,是指雨燕目雨燕科部分雨燕和金絲燕屬的幾種金絲燕分泌出來的唾液,再混合其他物質所築成的巢穴,而非雀形目燕科鳥類(如家燕)所築巢穴。
------------------------------------------------------------------------
產自中國南部沿海一帶、越南泰國馬來西亞印尼菲律賓等地。燕窩按築巢的地方而分為「屋燕」及「洞燕」兩種。「屋燕」的巢一般築在人工特意精心搭建的燕屋上,目的就是要方便採集燕窩,而洞燕的巢則築於山洞內,地勢險峻,採集相當危險。
典型的燕屋
燕窩中有红色稱為「血燕」的,传说中是因為金絲燕未完成鳥巢,忍著不產,吐而形成。事实上红色燕窝的形成的原因说法不一,比较可信的说法是:只有洞燕窝巢被含元素的岩壁的矿物质或水滴渗透,燕窝呈现出不规则、晕染状的铁锈红时,才会产生血燕。还有一种说法「棕尾金絲燕 」的食物中包含海藻等物使其唾液含雜質,氧化鐵含量較高,因而顏色鮮紅如血。血燕比起其它的燕窩,含更多的铁。
燕窩被採摘之後,還要經過蒸細、浸泡、除雜、挑毛、烘乾等複雜的加工才能製成燕窩成品,包括燕盞、燕條、燕餅、燕絲。其中燕盞是整隻優質的燕窩經除雜保留原有形狀而成,故價格特別昂貴。
-----------------------------------------------------------------------------------
王世懋之《閩部疏》王氏謂「燕窩菜,竟不辨是何物,漳海邊已有之。燕飛渡海中,翮力倦則擲置海面,浮之若杯,身坐其中。久之,複銜以飛。多為海風吹泊山澳,誨人得知以貨。大奇大奇!」中國有食用燕窩記載,自明朝始,傳說中國第一個吃燕窩的人是明朝航海家鄭和。從明朝開始,燕窩成為宮廷禦膳。明朝的《宛署雜記》一書中提到南北官府的大宴已有用燕窩製作的菜肴。直到清代,仍是「貴家珍品」,非尋常人家可食用。

----------------------------------------------------------------------------------
针对早前内地指燕窝含亚硝酸盐,香港本地专业燕窝商委托科大中药研发中心抽验市面47个来自印尼、马来西亚、泰国和越南的白燕窝、黄燕窝和血燕窝样本,并对比20个取自马来西亚和印尼的天然燕窝样本,结果发现2组样本均含亚硝酸盐和硝酸盐,含量相若。
科大指出,燕窝表面容易沾染亚硝酸盐,血燕犹甚,但经长时间浸洗和炖煮后可除去九成七亚硝酸盐,符合食用标准。
科大中药研发中心主任詹华强说,全部本地样本均验出含亚硝酸盐和硝酸盐,亚硝酸盐含量由每公斤5毫克至6400毫克不等。参照香港就鲜肉或肉类制品的亚硝酸盐和硝酸盐含量标准,而被抽查燕窝平均每公斤含1000至2000毫克亚硝酸盐,“超标”最严重的一个血燕样本更验出每公斤含6400毫克亚硝酸盐,“超标”达31倍。

加强记忆力--健脑药膳


适当药膳能有效加强记忆力

中医学所认为小儿无记性者,是脑髓未满;高龄无记性者,是脑髓渐空。小儿脑髓渐满则精智渐长。中医所讲的脑髓即脑与脊髓之合称。由脊骨上行人脑之精髓。其位于椎管之内,下至尾骶,上通于脑。中医健脑益智有其独到之见解,也有多种养生法来达到强脑增智的目的。

智力不足是由于肝肾亏损,心气不足,脾肾两亏,气血虚弱等所致。常见症状有语言迟钝,词不达意,视物模糊,记忆力欠佳,对外界事物反应迟钝,思考问题迟缓等。

营 养不良对大脑和智力发育有着重要影响。实验证明:营养不良可使脑细胞变小。脑细胞的突触减少,突触分支的形式改变造成脑部发育缺陷。而大脑主要需要糖、蛋 白质、脂类、微量元素、维生素A、B、C和E等营养素。因此合理摄入蛋、肉、奶、大豆、猪羊脑、干果、蔬菜、水果等食物,将有益于营养大脑。 儿童健脑食物要荤素搭配,尤其要多吃碱性食物即含钠、钾、钙、镁等丰富的食物。

中医强调饮食有节,起居有常,劳逸适度等能保精养血,积 精而神全。 精血是神不可缺少的物质基础,有精才有神,才能发挥思考能力。中医也说脑藏神,精神愉快则脑不伤。如精神紧张,心境不宁,神乱神散,则脑受损。而现代营养 学家则认为,除各种维生素及无机盐外。要使脑能够高效率地工作,必须保证氧气,水分、葡萄糖、蛋白质和脂肪类五种基本物质的供应。

鱼肉脂肪中含有对神经系统具备保护作用的欧米伽—3脂肪酸,有助于健脑。研究发现每周至少吃一顿鱼特别是三文鱼和沙丁鱼的人,与很少吃鱼的人相比较,老年痴呆症的发病率要低很多。吃鱼还有助于加强神经细胞的活动,从而提高学习和记忆能力。

全麦制品和糙米,增强肌体营养吸收能力的最佳途径是食用糙米。糙米中含有各种维生素,对于保持认知能力至关重要。其中维生素B6对于降低类半胱氨酸水平最有作用。

鸡蛋中所含的蛋白质是天然食物中最优良的蛋白质之一,它富含人体所需要的氨基酸,而蛋黄除富含卵磷脂外,还含有丰富的钙、磷、铁以及维生素A、B、D等,适于脑力工作者食用。

勤于思考分析的人,脑血管经常处于舒张状态,从而使神经细胞得到良好的营养,大脑功能就得以更佳的发挥。脑组织对毒物的作用十分敏感,凡有毒物质、环境污染、吸烟等都能损害脑的功能,必须加以防范和节制。多吸收新鲜空气,加强运动,增加大脑的氧供给。

一个人的道德修养和记忆力也有关系。如一个胸襟狭隘,凡事斤斤计较,七情易动的人,则脏腑气血功能往往会失调而伤脑,所以重道德修养;如豁达大度,恬淡寡欲,不患得患失,不追名逐利,悠然自得,助人为乐,就利於养脑。故健脑养生,尤当注意及此。

中医古今所用健脑方药,一般是以补肝肾、益精血的药如山萸肉、地黄、首乌、枸杞子、菟丝子、五味子、川杜仲、牛膝、当归等为主。另外也以黄芪、人参、丹参等补益元气。药膳配伍应用,当根据辨证论治的原则,有针对性地配制,疗效会较显著。

Brain Power The Herbal Nutrition Way
by C M Dr. Allen K.M. Pang (President of SEL & KL Association of China Graduated Chinese Physicians)

Children do have a better memory than old folks as this is because the young ones's memory filing system has not been fully stored. Being old, there are fewer brain cells available for taking in new information.

Poor memory also stems from failing function of the liver, kidneys, poor immune response, slow blood circulation. Some elderly with bad memory function can have speech impairment, bad hearing, failing eyesight and loose interest in general activities.

A poor diet lacking in many nutrients can shrink brain cells as the brain needs nutrition like protein, fats, element of trace, vitamin A, B, C, E. Food packed with these powers are found in eggs, meat, milk, whole-grains, pig's brain, sheep brain, nuts, fresh vegetables, fresh fruits. Children's meals should include sodium, potassium, calcium, magnesium.

In oriental theory for the brain to function its capability, you must have a happy

environment, no nervousness state or feel uneasy over things. A calm state of mind helps a lot. Nutritionists believed that the five key elements of good brain power stem from a good breathing system, adequate water in the body for its functions, glucose, protein and fats at a correct level which can drive a healthy brain and the nerve cells well.

Fish especially salmon and sardines are packed with omega-3 which the mineral calcium also play an important role in brain function.

Whole grain has vitamins especially those found in unpolished rice as vitamin B1 is present in the outer layer of the grain. Vitamin B6 present in whole-grain, legumes play an important role in regulating mood, sleep and appetite.

Eggs has good vitamin A, B, D and loads of protein and help to maintain healthy nervous tissue.

Avoid smoking, environmental poisoning as it endanger the brain cells but fresh air and exercises will increase good brain cells. Happy lives can contribute a long way as sufficient rest and good mood swings improve both concentration and less mental stress.
