癌症患者需要有足夠的體力以對抗病魔與面對一連串的的治療。補充麩醯胺酸,能給予人體所需養分,並有效降低、減輕口腔黏膜潰瘍或腸胃道損傷等化療、放療副作用。
當癌症病患接受化療和放療,難免會有副作用,如:放射性治療可能會造成局部組織發炎、黏膜潰爛,而化療會有掉髮、噁心 嘔吐、腹瀉等症狀,骨隨造白血球功能績效下降,因而亦受細菌、病毒感染,引發併發症。所以如何正確地補充體內所需養分,在此時更顯重要。
人體的構成物質之ㄧ為蛋白質,蛋白質即為胺基酸,是提供人體建立與不斷置換體細胞所需的原料。麩醯胺酸約佔人體胺基酸的六成,含量最為豐富。不同的胺基酸有不同的功能與吸收方式,許多的胺基酸是透過腸道黏膜細胞吸收並運送至人體各組織,因此維持腸道的健康是非常重要的。
根據馬偕醫院血液腫瘤科主治醫師張義芳醫師表示,通常一般人可透過飲食攝取足夠的麩醯胺酸,不需額外補充。但,當身體出現狀況時,特別是癌症患者, 因接受治療造成口腔黏膜潰瘍時,因疼痛難耐而無法進食,或者因過度腹瀉降低養份吸收效能,人體無法透過飲食獲得充足的養分,就需要透過其他方式,已獲得人 體所需大量的麩醯胺酸。
服用含麩醯胺酸食品,能改善吸收不良與補充蛋白質流失的問題。在臨床上有證據顯示,麩醯胺酸有其醫療效果存在,特別是針對腸黏膜受損的患者,有改善黏膜傷口癒合的功效。針對馬偕醫院而言,接受化療的病患,服用麩醯胺酸後也確實能有所助益。
張義芳醫師表示麩醯胺酸並非萬能,不適用於所有接受化療或放射性治療的癌症病患者使用。根據目前的文獻資料和研究指出,麩醯胺酸病不能治療癌症,僅針對音放射性治療或化療造成頭頸部和腸道黏膜受損的病人有所幫助,因為麩醯胺酸能補充黏膜受損後復原所需的物質。
日前衛生署已核准了一種含左旋麩醯胺酸的產品上市,作為特殊營養補充品。雖然國內將此產品規於食品類,而非醫療用品。但有關病人是否適合食用此類食品,還是請教專業醫師為佳,以免造成身體負擔,反而不利健康。

麩醯胺酸是種很好的營養食品連專業醫生都肯定與推荐 , 然而眾所不知 , 目前坊間賣的大都是合成的左旋-麩醯胺酸(L-Glutamine) , 而非天然的麩醯胺胜肽Glutamine Peptides , 所以為了健康還是盡量選天然的比較好 .
美安「先進纖維粉」本產品中含有天然的L-Glutamine 1,000 mg
High-protein foods including meat, fish, beans, and dairy products are excellent sources of glutamine. L-glutamine
is an amino acid derived from another amino acid, glutamic acid.
Glutamine is a restorative amino acid that is used by the GI tract as
its source of fuel. Pharmaceutical companies sell it as a medical food for GI healing. Glutamine
plays a part in the health of the immune system, digestive tract, and
muscle cells, and other various bodily functions. Heavy exercise, infection, surgery, and trauma can deplete the body's glutamine reserves, particularly in muscle cells.
Due
to the fact that the cells of the intestine use glutamine for fuel,
the supplement has been tried as a treatment for various digestive
conditions. It has been tested for usage in reducing diarrhea and symptoms of inflammatory bowel disease, otherwise known as IBS. Also, glutamine has been suggested to possibly help in the treatment of diseases that affect the small intestine. Glutamine also helps to reduce leakage through the intestinal wall. Thus, glutamine has been proposed as a treatment for food allergies as in leaky gut syndrome.
