这些毛病易致钙流失
很多人以为,通过饮食可以补钙,但实际上在日常饮食中,很多不经意、不正确的膳食行为会让你丢失大量的钙。
磷多丢失钙:钙磷比例失衡是导致人们缺钙的元凶。正常情况下,人体内的钙∶磷比例是2∶1,然而,现实生活中,人们过多地摄入碳酸饮料、可乐、咖啡、汉堡包、比萨饼、小麦胚芽、动物肝脏、炸薯条等大量含磷的食物,使钙∶磷比例高达1∶10~20,这样,饮食中过多的磷会把体内的钙“赶”出体外。
补钙不补镁,吃完就后悔:人们补钙的时候,只注意补充维生素D,却往往不知道要补充镁。钙与镁似一对双胞胎兄弟,总是要成双成对地出现,而且钙与镁的比例为2∶1时,是最利于钙的吸收利用的了。所以,在补钙的时候,切记不要忘了补充镁。含镁较多的食物有:坚果(如杏仁、腰果和花生)、黄豆、瓜籽(向日葵籽、南瓜籽)、谷物(特别是黑麦、小米和大麦)、海产品(金鱼、鲭鱼、小虾、龙虾)。
大鱼大肉“吃”掉钙:高蛋白饮食是引起骨质疏松症的原因所在。有人做过这样的实验:A:每天摄入 80克的蛋白质,将导致37毫克的钙流失;B:每天摄入240克的蛋白质,额外另补充1400毫克的钙,将导致137毫克钙的流失。额外补充钙并不能阻止高蛋白所引起的钙流失,过量摄入大鱼大肉而不注意酸碱平衡,将导致钙的大量流失。那么,怎样饮食才能促进钙吸收?维生素C促进吸收钙:把含钙高的食物与维生素C和泡菜汁一起服用,或者每天自己制作脐橙、柚子、橘子、芦柑、柠檬饮用,其生物利用度要增强12%。显然是这些水果中大量的维生素C的参与,使得钙能更好地被小肠吸收。
荤素平衡提高钙的利用率:比如豆腐炖鱼,鱼肉中含维生素D,豆腐含钙丰富。维生素D可促进钙的吸收,使豆腐中钙的利用率大大提高。另外,主食讲究谷豆类混食,不仅能使氨基酸互补达到最理想化,还能促进钙的吸收。

There was once a child, and he strolled about a good deal, and thought of a number of
things. He had a sister,
dog collarswho was a child too, and his constant companion. These two used to wonder all day long.
They wondered at
the beauty of the flowers; they wondered at the height and blueness of the
sky; they wondered at the depth of the bright water;

wondered at the goodness and the power of God who made the lovely world.
They used to say to one another,
dog
foodsometimes, supposing all the children upon earth were to die, would the flowers,
and the water, and the sky be sorry? They believed they would be sorry. For, said they, the
buds are the children of the flowers, and the little playful streams that gambol down the
hill-sides are the children of the water; and the smallest bright specks playing at hide
and seek in the sky all night,

harnessmust surely be the children of the stars; and they would all be grieved to see
their playmates, the children of men, no more.
There was one clear shining star that used to come out in the sky before the rest, near
the church spire,
dog leashesabove
the graves. It was larger and more beautiful, they thought, than all the others, and every
night they watched for it, standing hand in hand at a window. Whoever saw it first cried
out, "I see the star!" And often they cried out both together, knowing so well when it
would rise, and where. So they grew to be such friends with it, that, before lying down in
their beds, they always looked out once again,
dog productsto bid it good-night; and when they were turning round to
sleep, they used to say, "God bless the star!"
But while she was still very young, oh very, very young,
dog shoesthe sister drooped, and came to
be so weak that she could no longer stand in the window at night; and then the child looked
sadly out by himself, and when he saw the star, turned round and said to the patient pale
face on the bed, "I see the star!" and then a smile would come upon the face, and a little
weak voice used to say,
