维他命的作用是什么,它能不能提供能量啊?

维他命护肤品都适合一般性的皮肤群,只要在安全的浓度下就会对皮肤有正面的帮助.如维他命E适合所有皮肤,因为其功用是滋润及保湿,不会造成敏感.
但当然油性与干性皮肤在护理上也许有些分别,举例如暗疮性皮肤,使用维他命B护肤品可增加皮肤的新陈代谢,减低色素及有去印功效.
而干性皮肤使用AHA或BHA可能会令皮肤更干,甚至脱皮.
外涂更见功：
所有的护肤配方如维他命E、C、B等都是直接涂于皮肤上比吞食维他命药有效,由于维他命广泛地分布在不同的食物中,如果饮食均衡的话,缺少某种维他命的机会颇低,固此多服一两片维他命丸不会对皮肤产生显著改善；反而涂上护肤品,皮肤直接吸收,效果更好.据资料指出,我们经口服的维他命,其中有5%会氧化分解为二氧化炭,35%化为其它物质,只有60%会随血液循环运送至所需的器官并发挥其功能.
水溶性维他命：
维他命B3、B5、C都是水溶性的,通常储存在体内不会太久,不会造成积聚过多而产生毒.
另外,维他命B及C较其它的如维他命A稳定,不容易变质,可存放日子较长.
而且维他命B的刺激性较低,不易产生皮肤敏感.最近有指出维他命B对肌肤美白有明显功用,但其原因仍在研究之中.
维他命家族：
1.维他命B3
维他命B群其中包括B3.B3又俗称箊碱酸,将皮肤的表层细胞由老化阶段提升至新生阶段,促进皮肤新陈代谢；此外维他命B3可促进真皮中的骨胶原蛋白生长,减少水分的流失,从而使干纹减少.
含维他命B3的日常食物有肝脏、鱼、蛋、乳酪、小麦胚牙及肾脏等.
2.维他命原B5
曾试用在护发素中,将水分锁在发丝上,有补湿功能.使用于皮肤上可令皮下水分互相紧扣,滋润皮肤,避免出现缺水情况.动物的肝及肾脏或龙虾、扁豆都含此维生素.
3.维他命E
皮肤受游离基(刺激分子)的影响可会出现衰老情况,而维他命E主要的抗氧成分可使皮肤减少氧化,使肌肤更幼嫩及滋润.另外,维他命E也是一种预防癌症及心脏血管毛病的抗氧化剂,由于其抗氧成分,亦可使细胞减少氧化,延缓衰老.维他命E主要可在蛋黄、深绿色蔬菜及植物油中找到.
4.维他命C
维他命C中也含抗氧成分,可防衰老；亦可对皮肤的黑色素减低,有去印及美白作用.
柑橘类水果、蕃茄和马铃薯都含丰富维他命C.
5.维他命A
吸收不足可能会导致皮肤发炎或甚至眼睛出现毛病.
维他命A可使皮肤出现脱皮现象或敏感,一般用于改善油性皮肤或治疗暗疮皮肤.含维他命A的食物有白菜、胡萝卜、木瓜及芒果.
维他命与矿物质
要增加维他命就要有矿物质的辅助,因此要维持两者于体内的平衡.例如：
1.摄取过量的磷,会消耗钙,缺钙容易引致骨质疏松.
2.摄取过量的锌,会消耗铜和铁,缺铜头发颜色会变差,缺铁会贫血.
3.摄取过量的维他命C,会失去叶酸和维他命B12,缺乏这两种元素会易疲劳及贫血.

Ladies and Gentlemen, Good morning! I’m very glad to stand here and give you a short speech.
　　Man’s life is a process of growing up, along this ,there must be someone Who has a great effect upon You .So my topic today is:who do you admire most.
　　Maybe your idol is a scientist an athlete or a movie star.But for me Well Lee is the very person i admire most!And i believe you will agree with me if you know about this:several months ago he was a ordinay person as we are.However in fact he's not that easy,beacuse he had a dream.When Well was little,he showed a great gift of singing,and being a singer was what he had ever been dreamed of.Now he is popular with our young people.Beacuse he's not only a deamer,but a brave young man who tris his best to achieve his dream!
　　Yes,that's him:aways be nevours but never give up,aways perform well but never be arrogant,aways under pressure but never lose control.Hardworking、modest、friendly he's more than a goodlooking young singer,but a great model who deserves our learning.Well has a deal with his fans：No studying,No cheering!（不努力 不学习~嗯嗯!大爱!LL54哈~）It means if we fans don't study hard,we are not allowed to give him our cheering!I feel so proud of being one of his fans,and i will carry out our deal——to be a good student,do my best on my study and give him all my cheering!
　　That's all.Thank you.

就是说李炜从23万人中走来,这句话是在他12强时说的,所以是12,一位数是1~10,最后的一位数,就是说他想当冠军.
你也是维他命吧?
我也是的!
（李炜不红,天理不容!）

维他命的发现 ,你最好先上网找找中文的,然后让别人把你翻译一下,加一点你自己的想法最好

This is a supplement meal rich in calcium,iron,protein and vitamins as well as other nutrients necessary for the growth.

吾.我们班有一次作业是些诗歌、我写李炜的.结果被骂死.
同学还那里幸灾乐祸.

1.keep sb.in good shape by vitamins
2.maintain a good health by vitamins
3.require vitamins to remain healthy

书籍作为精神食粮,对人的影响很深、很远、很大.

维他命是音译,维生素是意译,即维持生命的元素.
维生素：各种脂溶性或水溶性生命物质之一,少量的这种物质对生命体的生长和活动至关重要,通常从植物食物中取得

Fruits,are essential to people's lives things.Fruit is not only delicious,but it is rich in vitamins,is conducive to our health.However,the time to eat fruit is also very important,the same fruits,evening and morning food selection are different.
The morning is the best time to eat fruit,just to get up because when the stomach was not yet ready,but required supplementary nutrition,fruit is the best choice.However,if you eat fruits at night,not only difficult to digest,will increase the burden of gastroenteritis.
So keep in mind that morning,eating fruits are gold,silver at noon,the evening is copper.
