離子鈣(1)
相信大部份香港人或居住在都市的人,對於鈣絕對不會陌生,很多人亦用了種種方法為身體補充足夠的鈣質,而市面上和網上亦有不同類型的補充劑可供選擇,既然是這樣,我們對於如何有效地用鈣與及其補充劑,是否有足夠的知識呢?我們如何選擇一種最合適的鈣呢?
一般來說,市面上可以購買的鈣補充劑分為:碳酸鈣(Calcium Carbonate)、檸檬酸鈣(Calcium Citric)、加鈣奶粉、合成鈣等等。但如果仔細查看資料,就很容易發現以上所提到的鈣質,是很難被人體吸收和運用,更不用說讓鈣質加強骨骼的密度。
科學家研究發現,有一種鈣的形態是能夠解決以上所提到的問題,使人體容易吸收,並且有效地補充骨骼所需的營養,從而增加骨骼的密度,這種就是:「功能性的離子鈣」。
功能性的離子鈣,能夠打破一般「結合鈣」不易為人體吸收或有導致結石的缺點,促進新陳代謝和骨骼及牙齒生長,高效補鈣、增加骨密度、減少骨鈣流失,並能達快速結合、分解、中和等新陳代謝之效果。
鈣為一種重要的營養素,但任何營養都自有適量及平衡。像每天所吃的餐食熱量(Calorie)也訂有基準,如有超過不但徒費,而且損害胃腸。鈣也是一樣,如過量的攝取,不但徒費,過度時甚致可能產生「鈣過多症」。但若攝取離子鈣就不會有所謂的「鈣過多症」。
離子鈣是非結合性鈣,能完全溶於水而呈離子化現象,使構成分子或分子團,帶電荷自由游動並具活性化。屬於水溶性鈣素,無酸根結合,所以沒有任何副作用。人體很容易全部吸收,使之維持體液和血液的酸鹼平衡,所以稱為活性離子鈣。


離子鈣(二)
活性離子鈣的任務在人的體液和血液呈酸性化時,能主動中和酸性物。平常是和碳酸鈣結合在一起,並存在血液中。若和碳酸鈣或硫酸鈣之類的強酸相遇時,在碳酸鈣中的鈣離子便會立即被分解出來,再和硫酸化合成為中性的硫酸鈣與二氧化碳及水一起排出體外,所以一定不會有攝取過剩的問題。
由上述可知,血液最好的狀態,就是必須經常保持相當數量的抗酸活性鈣離子,讓血液有適當的鹼性,隨時化解體內酸質,把有害的物質排出體外。
世紀新醫學.新觀念活性離子鈣之簡介,鈣離子是一種水溶性的離子化高科技高吸收的活性鈣劑,不同於一般醫學常用的結合鈣片,因屬活性故稱為活性鈣,容易吸收且容易排出,不會造成人體負擔,其特性如下:
1. 鈣離子是一種以鈣為主的離子化礦物質群,乃是細胞所需的營養,可使細胞快樂、活潑。由於鈣離子屬於鹼性,故可中和體內酸毒,控制細胞的通透性,促進新陳代謝,恢復疲勞、減少疲勞感,調節生理機能。
2. 當人體細胞有了好的生存環境後,必會認真的各司其職,達到人體健康維持。
3. 維持血液潔淨,中和體酸而達到淨血效果,幫助消化道機能,改變細胞生態環境和體內循環系統、代謝廢物排出體外、增強新陳代謝效能持續血液之潔淨,皮膚細胞得到新陳代謝後,即達到真正的人體健康。
4. 美顏美容,控制細胞的通透性,達到真正的體內革命,亦即外貌體態的改善,外表要年輕只有改善體內的毒素才能達到人體健康。
5. 鈣是構成牙齒與骨骼的主要成分,能夠維持骨骼與牙齒的健康,所以要多補充含鈣的食物。
6. 活化凝血酯元轉變為凝血幫助血液凝固。
7. 產前、產後或病後之補充。


離子鈣(三)
首先我們開始探討一下鈣的主要用途,生命就是一部「鈣」的進化史:科學家曾把「海膽」卵泡,浸入高鈣的組織液中,短期內經無性生殖,可產出一堆沒有生命的肉團,注射鈣劑給一顆靜止的心臟,又會恢復跳動。
鈣對於生命是非常之重要,如果含鈣量不足,就會造成身體的大災難。鈣可以創造生命、豐富生命、繁殖生命。
(骨鈣、血鈣的主要用途)
1. 「止血」:凝固撕裂傷口的流血現象。
2. 「活化」:對血液中酵素有活化作用。
3. 「解毒」:酸、鹼中和體內積存已久之酸毒。
4. 「消炎」:減輕各種炎症,達到殺菌的功效。
5. 「收縮」:活化細胞、增進肌肉之收縮。幫助健身或運動時,肌肉和神經線產生爆發力作用,所以吃離子鈣會增加運動時肌肉爆發力度。
6. 「淨血」:降低血液膽固醇、恢復血管彈性 。
7. 「強化」:鈣離子能強化骨本、預防骨質疏鬆。
8. 「滲透」:活性遊離子鈣,有效調整細胞膜的壓力和滲透力。
9. 「安定」:調整神經興奮度、改善大腦皮質不均。
10. 「調節」:調整自律神經、使內分泌更加順暢。
11. 「傳達」:離子鈣是神經線的傳度,使我們反應更快。
12. 「平衡」:藉鹼化身體,維持身體正常的Ph席,達至身體平衡的健康,血氣暢順。


離子鈣(四)
維持健康的四大要素
(1) 淨化腸道、充足睡眠、適當運動、緩解壓力,維持鹼性體質有兩個主要方向:一是減少酸毒的累積,二是勤造鹼性體質。如果一方面排毒,卻一方面不斷提供酸毒上身的機會,就是大羅金丹也無濟於事。
早於1908年諾貝爾醫學得主“梅基妮可夫”教授就指出「現代飲食多為高蛋白、高脂肪食物,因為難消化,所以容易附著腸壁,積成腐臭宿便,日久將引發慢性中毒,加速細胞衰老,百病纏身?」
所以常言道:萬病因酸起,但腸毒卻是酸害之首。腸道壞菌過多(大腸菌、葡萄球菌),易滋生腐胺素、琉化氫、雲朵…‥等致癌物質回流全身。「糞氣」自肺出,即生氣喘;自皮膚出,便長濕疹;上衝腦門就會導致昏沉及失眠。所以健康之道首在「淨化腸道」。
腸道健康,才能大舉吸收營養素,身體自然更健康,所以平常要多吃綠色疏菜,少吃肉類,必須嚴格遵守低糖、低鹽、低蛋白質、低脂、極高纖維(四低一高)之飲食原則。
(2) 每天十點準時睡覺也必須落實。因為肝、膽要啟動解毒與代謝的時間點,就在晚上十一點至三點鐘。有可能因為電視越晚越好看所以第二天早上就睡眼惺忪,結果整天就會精神不濟、事倍功半。
這在中醫解釋,因為「氣」無血不旺,「血」無氣不行,熬夜會讓氣血兩虧,血液相形汗濁;「酸性體質」不都是這樣產生的嗎?
(3) 肥胖與懶惰正是兩個好兄弟,中年發福的人則感觸特別深,能夠抽出時間多多運動的人還真是不多見。其實腳是我們的第二顆「心臟」,老化就從腳開始。
如不能抽空運動,多走路也可以增加「體適能」,每天快步走一萬步,大約30-40分鐘也能促進血液循環,能有效治療肩頸酸痛及彎腰駝背;至少心肺功能增加些,關節更順暢些;走路也可以反省很多事,使生活可以適量地作出微調。
(4) 壓力也是製造酸毒的元兇之一,這牽涉到個人對事物的價值觀及處世能力而定,這也是慢性病的無形兇手。
所以縱觀以上四點(飲食、睡眠、運動、壓力),都是鈣離子所無法代替的,甚至是超越醫學所能影響的。如果有人因此吹噓說鈣離子可治百病或極力排斥現代醫學者,此舉不僅自曝其短,充滿以偏蓋全的無知。因為有病須得看醫生,「鈣離子」只是幫助改變酸性體質而已。


離子鈣(五)
基本上,人類體質可區分酸性、鹼性兩種,而大部份疾病都是由酸毒所引致,酸毒包括體內的:尿素氮、焦葡萄酸、磷酸、二氧化碳、氨氣等等。
實際上,要處理酸毒問題並不困難, 只要藉飲用鈣離子及鹼性水中和並排掉,疾病自然也就沒了,此即所謂「扶正去邪」之義。
工業化所帶來的「空氣污染」、「水源污染」、「藥毒污染」等,早把人類推向「酸性體質」的深淵。可以很悲傷的說,在我們這一代絕對不可能見到有任何改善的機會;我們勢必要自求多福,才能多少免於被工業化所毒害。因為我們還有一個切身的「善終」問題要解決;連累家人,或增加社會成本都是小事,但自身所得到的病痛與折磨,才是最難熬的大苦難。好漢最怕被病來折磨;所以人生在世只有兩件大事,一是把身體照顧好,二是做應該做的事,這樣才對得起自己,才不枉費神把我們放在這個世上。
到底,人體的「酸毒」是從何而來呢?
 獸肉之毒:抗生素、賀爾蒙、生長激素、屍毒;
 加工之毒:色素、防腐劑、人工添加劑;
 蔬果之毒:農藥、化學肥料、殺菌劑、保鮮劑;
 醫藥之毒:退燒藥、抗組織氨、類固醇、麻醉藥;
 衣物之毒:螢光劑、增艷劑、漂白劑、溴酸鹽元劑;
 居住之毒:消毒水、芳香劑、化學塗料、粘劑、殺蟲劑;
 空氣之毒:懸浮粒、氟氯碳化物、鉛、輪胎粉末、煙毒;
 化妝之毒:色素、香料、抗氧化劑、甲苯、甲醛等。
「鈣離子」經高溫電解後,帶雙正電且不飽和;固活性非常強,可將帶負電離子的酸毒、菌體破壞。若沖泡成離子水,能快速將中和後之毒素排出體外;固氣又被尊為:大自然之「水醫生」。


離子鈣(六)
離子鈣是經過3500度以上的高溫高壓在真空電解下使其氣化,用特殊高科技方法製造,產生以鈣離子為主的離子化礦物質群,在人體內呈游離狀態,由於是不需要再經過消化過程分解便能直接吸收利用,不但吸收率高,而且能迅速中和人體內的酸毒。
現代人逐漸忽略和淡忘了水本身具有的保健療效作用,只注意了水的純淨而忽略了水的生理作用。水的純淨與健康是兩回事。水的純淨主要針對水污染而言,健康的水主要針對人體健康來說,純淨水不等於健康水。
鈣離子水做到了純淨與健康的統一,因鈣離子屬鹼性,故可中和人體內的酸毒,使人體的體液和血液維持於健康的弱鹼性狀態。
對於身體有各種病況的人,剛接觸鈣離子水,一開始會覺得精神或體力愈來愈充沛,這是人體內的酸毒逐漸減少而使細胞逐漸恢復活力的結果,這時人體的自然治愈力也隨之增強,一直到人體自認為已有能力自我改善時,人體就會逐步的進行改善自己,這時所謂 「好轉反應」也就會逐步出現了。
好轉反應例如:腹瀉、皮膚腫癢、疲勞或手腳發軟現象,表示身體正排除多年囤積的廢物毒素。好轉反應通常是在三至七天左右就會自然消失,較強烈的只有二或三天而已,當然不是每個人都有這種現象,而是因個人體質而定,不過無論如何都不會使病症產生惡化現象,因此只要是出現有強烈的好轉反應現象的人,只是顯示其本身健康情形不佳而已,所以不必過於驚慌。
例如,對於高血壓病人,剛開始飲用鈣離子水可能會有血壓加高現象,而後漸趨好轉;配合藥物時,藥量可漸趨減少。有胃腸疾病的人,有疼痛加劇現象,而後漸恢復胃腸功能。對於皮膚病,如青春痘、香港腳、膿疹、過敏等症,酸毒迅速由體內排出約1-3星期,傷口、膿、疹子可用鈣離子粉末塗於患部,香港腳用濃離子水泡腳則效果良好。


離子鈣(七)
離子鈣和目前醫學用或西藥房所賣的結合鈣片是完全不同的東西。一般的結合鈣劑大多屬於乳酸鈣(如牛奶裏的鈣質)、碳酸鈣、硫酸鈣等。這些結合鈣劑是屬於酸性,不僅無法中和現代人體內的酸毒,吃多反而會引起血管硬化或膽、腎的結石。
但鈣離子卻屬鹼性,它本身已經是一種離子元素,不必再經過脾、胃消化,人體就可以加以吸收利用。目前市面出售的鈣,大多是結合型鈣,並強調須配合維他命D、檸檬酸一起服用,才能被人體所攝取,其實這種結合鈣人體很難吸收利用。
為什麼很多患者吃鈣片和喝高鈣牛奶也沒效果?就是因為他們無法吸收到鈣片裡的鈣。但離子鈣就不需經過消化系統,所以人體可以100%吸收離子鈣。但在補鈣是時,也記得補鎂,因為要是人體缺乏鎂的話,人體內的鈣很容易流失。
有些人會擔心,當服用鈣的時候,身體會有可能產生結石的危險。但事實並非如此。
喝鈣離子水的杯子,為何使用日久,表面會形成一層白色霧狀。有人質疑這種現象是不是會產生結石?這點務請消費者放心,鈣離子水因水中含有高鈣、高氧及豐富的礦物質,尤其離子鈣的揮發性極大,與空氣接觸瞬間隨即產生氧化作用,形成結晶狀。這可從鈣離子水倒入杯中短短幾分鐘,水面即會形成一層油霧,水喝完杯內四周尚留水份,也是瞬間與空氣接觸氧化。自然也會有一層薄霧狀。但剩下的水絕對是百分百的高鈣好水,已去除所有不好的成份,所以不用懷疑和擔心。
鈣離子水,喝進體內立即藉由血液循環,隨血液以二十三秒繞全身一周的速度運作。因具滲透及分解力,會產生清除雜質的作用。尤其是尿酸(尿酸是強酸)它不是靜止停留在體內,定位在某一器官,所以不會也不可能有結石的現象產生。
常常有人擔心攝取鈣後會引起結石,這是很大的誤會。的確,分析結石時,其中含有若干的鈣,但事實上,結石的主要成份為膽固醇,即結石是因缺乏鈣質,並在酸性血液之情況下膽固醇固化而生成,如果血液有鈣離子且傾於鹼性,反而能溶解結石。在腎臟、膀恍,為避免造成結石,應多攝取鈣離子。


離子鈣(八)
「活性鈣離子的味覺」
人體健康必須維持弱鹼性的體質,現代人大多屬於酸性體質,身體越虛弱,毛病越多其體質則越酸性。偏離弱鹼性的體質越遠,喝鹼性的鈣離子水時,則很難入口,當體質隨著改善而漸漸偏向健康的弱鹼性時,喝鈣離子水後反而會覺得生醇甜可口了。當你喝了鈣離子水時,若有以下之味覺反應是正常,亦即表示你體內機能有失調反應。
1. 消化系統欠佳:
 喝鈣離子水有澀味反應,顯示目前的身體器官食道狀況可能其中有點問題。
2. 呼吸系統不良:
 喝鈣離子水會有臭味反應,顯示目前的呼吸器官健康狀況可能有問題。
3. 血液循環系統有毛病:
 喝到鈣離子水會有酸味反應。
4. 排泄系統不良者:
 喝到鈣離子水會產生苦味反應,顯示出目前的器官排泄能力不好。
5. 泌尿神經系統有問題者:
 喝完鈣離子後產生腥味、皮蛋味、馬尿味反應。
情緒的好壞也將影響味覺,當人體正在進行自我改善的好轉反應階段,味覺又不一樣,這種因人、因時而異的味覺,除了鈣離子以外,任何中西藥都不可能出現的清況!你說神奇嗎?
酸性體質者會強烈排斥鹼性水;藉由「五味」辨症:
 心臟不好的人喝起來是酸的;
 肝膽不好的人喝起來是「苦」的;
 腎、膀胱不好的人喝起來是「腥」的;
 腸胃不好的人喝起來是「澀」的;
 心臟疾病者喝起來是「酸」的;
 長期吃藥者味蕾堵塞者喝起來是「甜鹹」的。
每天的口感也曾因體質的改變而有所差異,當恢復成為鹼性體質者,口感就會趨於平淡或略帶甘甜。這期間不會太長,大都在90天內就能覺察體質之改變。


離子鈣(九)
鈣離子傳奇自古以來,中國道家術士追求煉丹化(氣)、羽化登仙。煉丹師將牡蠣貝殼洗淨後,直接以高溫鍛燒後,再研粉服用;但無法去除重金屬,所以往往適得其反、延生慢性中毒。
然而,時至今日假以新科技將高鈣礦物群物質(珊瑚、珠貝、鐘乳、龍骨),進行酸洗去蕪、高溫鍛燒,再進行研磨及氣化電解後;運用離子拮抗配方,去掉重金屬及有毒物質,並加入人體需要的微量元素後,就製成離子化的粉末,離子鈣有第一和第二代之分。古代修道人身穿布衣、身懷妙單,信手拈來此濟世良藥,固名之為「布丹」,亦即鈣離子之統稱。
在二戰期間,由旅日華僑李深泉老前人在適當機緣下,接受一位雲水僧所指導,將鈣離子生產上市,並運用鈣離子治癒了金鈣力公司王輝評先生的嚴重肝疾,那年正好台灣發生嚴重油毒事件(彰化發生多氯聯苯事件),群醫束手無策,鈣離子再度發揮強大威力,救了多人的性命(聯合--中時報章都大幅報導)。高鈣礦物在醫典中被當作外丹藥物,人身精氣被歸納為內丹藥物。並視大地為大爐鼎,人身為小爐鼎,丹行精氣,陽下陰上,水火相交,即可去病養身。
以現代觀點得知;鈣屬強鹼,適當用於人體,可收酸鹼中和之效。人體的70%水分中,細胞內則佔50%、細胞外則佔20%。利用水的滲透壓,鈣的強鹼能快速平衡細胞間質液中之(+ -)電解質。體內電解質失衡,亦會生成嚴重之「酸性體質」。鈣離子醫學推崇「萬病一言論」,闡述萬病都來自於一個源頭 ── 「酸」毒。所以只要將酸毒拿掉,那有所謂的高血壓或糖尿病、腎臟病呢?
但後人卻誇大成「一元」可以治萬病,用一元的「鹼」來對治萬病!這種神秘化作祟的陰影,讓正規醫者嗤之以鼻,直把這樣神奇的「鈣離子」降格為巫醫道術之流,這是很可惜的事。


離子鈣(十)
人體中的鈣質有99%存在於骨骼與牙齒中,是骨骼與牙齒主要的成份,其他的1%則存在於全身各處如軟組織及血液當中。
不要小看了這1%,它們的角色亦是非常之重要。因為神經傳導、肌肉收縮、血液凝固、心臟的跳動、荷爾蒙的作用等生理反應,都與它們有直接的關係。這1%是悠關生死的部份,因此人體的組織及血液中鈣的濃度必須保持恆定,不能太高也不能太低,否則會威脅生命安全。
鈣是人體很難攝取的一種礦物質,隨著年齡增長,鈣的吸收率和吸收量也降低。食物所含的鈣質,進入人體後先離子化,然後被吸收,如果沒有離子化,就無法被吸收運用。
在正常的情況下,30歲以前可以保持鈣的平衡,在嬰兒期以及青春期尤其明顯。這兩個時期也是人體成長發育最快的時期,在青春期注意鈣質的充分攝取,更有機會長高長壯。
30歲以後,鈣質流失的速率漸漸會大於鈣質吸收的速率,女性過了更年期,由於內分泌的改變,鈣質流失的狀況會更加明顯,此時也應該注意鈣質的攝取,並請醫師幫助你作適當的治療與建議。


離子鈣(十一)
今次讓我們花一篇短短的文章,讓大家對離子鈣的好處有一個深刻的記憶。
以下是離子鈣對於人體的十五種功能:
1. 淨化、淨血作用;
2. 促進肌肉和心臟的正常收縮;
3. 幫助凝血、止血作用;
4. 具消炎、止痛作用;
5. 安定神經作用;
6. 調整及美化皮膚作用;
7. 調節荷爾蒙、內分泌作用;
8. 幫助酵素產生、使酵素活性化;
9. 強化收斂作用及肌肉的感應性;
10. 解毒作用:能中和酸性、重金屬中毒;
11. 調節滲透壓、並控制細胞膜之通透性;
12. 使內臟活性;
13. 骨骼和牙齒的支持作用;
14. 控制神經傳導及感應性作用;
15. 促進細胞活化再生養顏功能。

“人体是一个小宇宙”的奥秘(图)2015-01-03 20:42
作者: 观心





人体是一个小宇宙(网络图片)
道家说:人体是一个小宇宙。人体的内部结构和运行原理和宇宙是一样的,这是中国中医的基础,中国有“十医九道”之说,过去的那些大医学家都是精通道家理法,行医是修行的一个方式。


人体有完整的免疫功能,侵入人体和人体产生的一些不好的东西,自己的免疫功能就会消灭掉和自然排除那些废物多余的物质,这叫“新陈代谢”。人们不知道的是,宇宙也是一个生命体,而且是一个高级生命体,其本身也有这种与人体一样的免疫功能,这个机制自动的清除那些宇宙垃圾的时候,道家把这个叫“损有余而补不足”,其实就是宇宙的“新陈代谢”。
人们说的宇宙大劫难,其实就是宇宙这个庞大身体的大面积的“新陈代谢”。这种宇宙的“损有余而补不足”现象,“损”的都是那些有害的败物,“损有余”的同时还会“补不足”,“补”的都是新能量、好东西!这就是我们观察到的宇宙星系大爆炸和星系重新组合及大量新的星系诞生的奥秘。
很多人都不相信善恶有报的道理,认为是迷信,其实,那是更高的科学,是宇宙这个生命体“损有余而补不足”的依据,这个机制就象人体的免疫机制一样,消灭的都是那些有毒、伤害细胞的败物,绝不会伤害身体的有益细胞,宇宙也一样:宇宙的免疫机制造成的新陈代谢,绝不会伤害宇宙中的那些善良和正义的生命!
把这个道理理清以后,人们就会明白:人除了做好人以外别无出路!人的自救的唯一正确道路就是做好人、做君子。否则,迟早会被宇宙的免疫机制淘汰掉:天作孽,犹可为;自作孽,不可活!
中华传统文化是多么高深,好东西都在中国这个“神州”,只是人们忘记了自己的文化,那是整个未来人类的希望。

Calcimn rich foods


Updated December 15, 2014.


According to the American Academy of Pediatrics, "The average dietary intake of calcium by children and adolescents is well below the recommended levels of adequate intake." This can mean that these children will not develop their optimal bone mass, which can put them at risk of fractures and osteoporosis.
Understanding which foods are high in calcium can help you ensure that you are encouraging your kids to get enough calcium in their diet by choosing calcium rich foods such as milk, cheese, and yogurt. Remember that children should eat 3 age-appropriate servings of dairy products per day (4 servings per day for adolescents) or the equivalent to get enough calcium in their diet.

It is also important to understand how much calcium kids actually need. The Food and Nutrition Board of the National Academy of Sciences recommends:
500 mg a day for kids who are 1 to 3 years old
800 mg a day for kids who are 4 to 8 years old
1,300 mg a day for kids who are 9 to 18 years old
Keep in mind that calcium's percent Daily Value (% DV), which is a guide to how much of a particular nutrient you should get each day, on food labels is based on the adult requirements of 1000 mg a day. So a cup of milk that was 30% DV for calcium, would be equal to 300 mg of calcium, which would actually be equal to 60% of a toddler's calcium needs for the day. But it would be only about 23% of a teen's calcium needs. That means that you can only really use the % DV as a guide to how much calcium your kids are getting from the foods they are eating each day.


Calcium Rich Foods


In addition to choosing foods from the following list, you should learn to look at food labels and choose foods that have a high % DV for calcium and at least 20% or more. You may find big differences in the calcium content of foods, even among different brands of the same foods such as cheese, juice, and bread.




Remember that just because your child is eating cheese, that doesn't mean that she is getting a lot of calcium. Check the nutrition label to make sure the cheese has a lot of calcium. And also look for foods made with these calcium rich foods as ingredients, such as a macaroni and cheese (cheese), pudding (milk), and nachos (cheese).
Nondairy Foods with Calcium


Getting enough calcium can be a especially hard if your kids are allergic to milk. These nondairy foods can be good choices for kids with milk allergies who need calcium:
Salmon
Tofu
Rhubarb
Sardines
Collard greens
Spinach
Turnip greens
Okra
White beans
Baked beans
Broccoli
Peas
Brussel sprouts
Sesame seeds
Bok choy
Almonds
Calcium-fortified Foods


In addition to the large number of calcium rich foods that are naturally found, like milk and cheese, a lot of foods are now fortified with calcium. These can be especially good choices if your child doesn't like to drink milk.
Calcium-fortified breakfast cereal, including General Mills Whole Grain Total, Total Raisin Bran, Total Cranberry Crunch, and Total Honey Clusters, all of which have 100% DV of calcium per serving!
Calcium-fortified orange juice
Calcium-fortified soy milk
SunnyD with Calcium (most SunnyD products don't have calcium, so look for the one that does if your child needs extra calcium in his diet)
Instant oatmeal
Calcium-fortified bread or English muffins
Calcium-fortified drink mixes such as Pediasure or Carnation Instant Breakfast
Other calcium-fortified breakfast cereals, including General Mills Golden Grahams (350 mg)
By learning to read food labels , you may be able to find other foods that are fortified with calcium.
What You Need To Know


Talk to your Pediatrician if you aren't sure if your child is getting enough calcium in his diet.


Most varieties of children's vitamins don't have much calcium in them and you may need a special calcium supplement instead.


Choose from a combination of calcium rich foods to get even more calcium in your child's diet, such as a grilled cheese sandwich using calcium-fortified bread and cheese or a calcium fortified breakfast cereal with half a cup of low-fat milk.


In addition to getting enough calcium in your diet, regular exercise is also important for healthy bones.

Calcium is a chemical element with symbol Ca and atomic number 20. Calcium is a soft gray alkaline earth metal, and is the fifth-most-abundant element by mass in the Earth's crust. Calcium is also the fifth-most-abundant dissolved ion in seawater by both molarity and mass, after sodium, chloride, magnesium, and sulfate.[2]


Calcium is essential for living organisms, in particular in cell physiology, where movement of the calcium ion Ca2+ into and out of the cytoplasm functions as a signal for many cellular processes. As a major material used in mineralization of bone, teeth and shells, calcium is the most abundant metal by mass in many animals.

Calcium is an important component of a healthy diet and a mineral necessary for life. The National Osteoporosis Foundation says, "Calcium plays an important role in building stronger, denser bones early in life and keeping bones strong and healthy later in life." Approximately 99 percent of the body's calcium is stored in the bones and teeth.[26] The rest of the calcium in the body has other important uses, such as some exocytosis, especially neurotransmitter release, and muscle contraction. In the electrical conduction system of the heart, calcium replaces sodium as the mineral that depolarizes the cell, proliferating the action potential. In cardiac muscle, sodium influx commences an action potential, but during potassium efflux, the cardiac myocyte experiences calcium influx, prolonging the action potential and creating a plateau phase of dynamic equilibrium. Long-term calcium deficiency can lead to rickets and poor blood clotting and in case of a menopausal woman, it can lead to osteoporosis, in which the bone deteriorates and there is an increased risk of fractures. While a lifelong deficit can affect bone and tooth formation, over-retention can cause hypercalcemia (elevated levels of calcium in the blood), impaired kidney function and decreased absorption of other minerals.[27][28] Several sources suggest a correlation between high calcium intake (2000 mg per day, or twice the U.S. recommended daily allowance, equivalent to six or more glasses of milk per day) and prostate cancer.[29] High calcium intakes or high calcium absorption were previously thought to contribute to the development of kidney stones. However, a high calcium intake has been associated with a lower risk for kidney stones in more recent research.[30][31][32] Vitamin D is needed to absorb calcium.


Dairy products, such as milk and cheese, are a well-known source of calcium. Some individuals are allergic to dairy products and even more people, in particular those of non Indo-European descent, are lactose-intolerant, leaving them unable to consume non-fermented dairy products in quantities larger than about half a liter per serving. Others, such as vegans, avoid dairy products for ethical and health reasons.


Many good vegetable sources of calcium exist, including seaweeds such as kelp, wakame and hijiki; nuts and seeds like almonds, hazelnuts, sesame, and pistachio; blackstrap molasses; beans (especially soy beans); figs; quinoa; okra; rutabaga; broccoli; dandelion leaves; and kale. In addition, several foods and drinks, such as orange juice, soy milk, tofu, breakfast cereals, and breads are often fortified with calcium.[33]


Numerous vegetables, notably spinach, chard and rhubarb have a high calcium content, but they may also contain varying amounts of oxalic acid that binds calcium and reduces its absorption. The same problem may to a degree affect the absorption of calcium from amaranth, collard greens, and chicory greens. This process may also be related to the generation of calcium oxalate.


An overlooked source of calcium is eggshell, which can be ground into a powder and mixed into food or a glass of water.[34][35][36]


The calcium content of most foods can be found in the USDA National Nutrient Database.[37]

Cancer
Overall, there is no strong evidence calcium supplementation helps prevent cancer in people: some studies suggest it might decrease the risk, but others suggest it might increase the risk. The National Cancer Institute, part of the National Institutes of Health, does not recommend the use of calcium supplements to prevent any type of cancer, due to the lack of evidence supporting its use for this purpose.[50]


There is weak evidence calcium supplementation might have a preventative effect against developing colorectal adenomatous polyps, but the evidence is insufficient to recommend such supplementation as a beneficial practice.[51]

Hazards and toxicity
Compared with other metals, the calcium ion and most calcium compounds have low toxicity. This is not surprising given the very high natural abundance of calcium compounds in the environment and in organisms. Calcium poses few serious environmental problems, with kidney stones the most common side-effect in clinical studies. Acute calcium poisoning is rare, and difficult to achieve unless calcium compounds are administered intravenously. For example, the oral median lethal dose (LD50) for rats for calcium carbonate and calcium chloride are 6.45[52] and 1.4 g/kg,[53] respectively.

Calcium metal is hazardous because of its sometimes-violent reactions with water and acids. Calcium metal is found in some drain cleaners, where it functions to generate heat and calcium hydroxide that saponifies the fats and liquefies the proteins (e.g., hair) that block drains. When swallowed calcium metal has the same effect on the mouth, esophagus and stomach, and can be fatal.[54]

Excessive consumption of calcium carbonate antacids/dietary supplements (such as Tums) over a period of weeks or months can cause milk-alkali syndrome, with symptoms ranging from hypercalcemia to potentially fatal renal failure. What constitutes “excessive” consumption is not well known and, it is presumed, varies a great deal from person to person. Persons consuming more than 10 grams/day of CaCO3 (=4 g Ca) are at risk of developing milk-alkali syndrome,[55] but the condition has been reported in at least one person consuming only 2.5 grams/day of CaCO3 (=1 g Ca), an amount usually considered moderate and safe.[56]

Oral calcium supplements diminish the absorption of thyroxine when taken within four to six hours of each other.[57] Thus, people taking both calcium and thyroxine (甲狀腺素(由甲狀腺產生,用來控制新陳代謝(身體中的各種化學過程)的一種激素,對兒童的正常發育十分重要)run the risk of inadequate thyroid hormone replacement and thence hypothyroidism if they take them simultaneously or near-simultaneously.[58][unreliable medical source?]

Excessive[vague] calcium supplementation can be detrimental to cardiovascular health, especially in men.[59][60]

Calcium is a mineral that is an essential part of bones and teeth. The heart, nerves, and blood-clotting systems also need calcium to work.


Calcium is used for treatment and prevention of low calcium levels and resulting bone conditions including osteoporosis (weak bones due to low bone density), rickets (a condition in children involving softening of the bones), and osteomalacia (a softening of bones involving pain). Calcium is also used for premenstrual syndrome (PMS), leg cramps in pregnancy, high blood pressure in pregnancy (pre-eclampsia), and reducing the risk of colon and rectal cancers.


Some people use calcium for complications after intestinal bypass surgery, high blood pressure, high cholesterol, Lyme disease, to reduce high fluoride levels in children, and to reduce high lead levels.


Calcium carbonate is used as an antacid for “heartburn.” Calcium carbonate and calcium acetate are also used for reducing phosphate levels in people with kidney disease.


Calcium-rich foods include milk and dairy products, kale and broccoli, as well as the calcium-enriched citrus juices, mineral water, canned fish with bones, and soy products processed with calcium.


Calcium can interact with many prescription medications, but sometimes the effects can be minimized by taking calcium at a different time. See the section titled “Are there any interactions with medications?"


How does it work?
The bones and teeth contain over 99% of the calcium in the human body. Calcium is also found in the blood, muscles, and other tissue. Calcium in the bones can be used as a reserve that can be released into the body as needed. The concentration of calcium in the body tends to decline as we age because it is released from the body through sweat, skin cells, and waste. In addition, as women age, absorption of calcium tends to decline due to reduced estrogen levels. Calcium absorption can vary depending on race, gender, and age.


Bones are always breaking down and rebuilding, and calcium is needed for this process. Taking extra calcium helps the bones rebuild properly and stay strong.

Calcium Dietary Supplement Fact Sheet
Introduction


Calcium, the most abundant mineral in the body, is found in some foods, added to others, available as a dietary supplement, and present in some medicines (such as antacids,a substance used to reduce or prevent acid collecting in thebody, especially in the stomach
解酸藥,解酸劑;抗酸劑;防酸劑). Calcium is required for vascular contraction and vasodilation, muscle function, nerve transmission, intracellular signaling and hormonal secretion, though less than 1% of total body calcium is needed to support these critical metabolic functions [1]. Serum calcium is very tightly regulated and does not fluctuate with changes in dietary intakes; the body uses bone tissue as a reservoir for, and source of calcium, to maintain constant concentrations of calcium in blood, muscle, and intercellular fluids [1].
The remaining 99% of the body's calcium supply is stored in the bones and teeth where it supports their structure and function [1]. Bone itself undergoes continuous remodeling, with constant resorption and deposition of calcium into new bone. The balance between bone resorption and deposition changes with age. Bone formation exceeds resorption in periods of growth in children and adolescents, whereas in early and middle adulthood both processes are relatively equal. In aging adults, particularly among postmenopausal women, bone breakdown exceeds formation, resulting in bone loss that increases the risk of osteoporosis over time [1].
