- Only 0.1% (1 in a thousand) of the defensive uses of guns results in the
death of the

bloodshed
than hurt a family member.
- Every year, people in the United States use guns to defend themselves

G***a 发帖数: 27294 | 2 姐姐,你要科普可以。。。。但是,,,
(1)果糖拼写是fructose。。。。如果不确定怎么拼,咱查一下是吧?
(2) 谁说水果里没有葡萄糖了?姐姐你好歹wiki一下吧?///
果糖/葡萄糖这个比值,低于1(也就是葡萄糖比果糖还多的水果)很多
比如杏0.7,桃子0.9, 香蕉是1(也就是葡萄糖果糖一样多),李子0.66
公平的说,也有果糖比葡萄糖多的水果,但是最多也就是2比1的关系,比如苹果和梨
所以,果糖,在任何水果中,都不像你说的,达到压倒性多数。
因此,吃4磅水果,一样葡萄糖过量。
(3)果糖一样引起insulin resistance。 你google一下
fructose and insulin resistance,一万篇文章
不抑制insulin,不代表不产生insulin resistance
好比连酒精都产生insulin resistance
(4)果糖过量比葡萄糖过量伤害更大,因为果糖需要肝脏代谢,而且产生毒物。
首先你可以搜fructose in liver
其次可以看看这个讲座,著名的sugar, the bitter truth

1. 吃大量的碳水会激发胰岛素分泌。但光吃肥肉也就是脂肪,不会刺激胰岛素分泌。
为什么说饮食中坏脂肪很多,胰岛素清除的就很慢?如果你是说坏脂肪和碳水一起
吃会影响胰岛素的工作,又为什么呢?脂肪和碳水混合会产生特殊效应会减慢胰岛素的

2.理解运动对改善insulin resistance的作用,但为什么是有氧运动呢?咱的理解是无
氧运动的作用更大,以至于举重后,专家都提议马上进补蛋白质和碳水,而且最好是简
单碳水。就是利用胰岛素的分泌迅速把血糖转换成肌糖原。
。。。
如果饮食中坏脂肪(比如饱和脂肪,反式脂肪,坏胆固醇)很多,胰岛素清除的就很慢。
所以达不到“迅速撤离”。长期摄入高糖高脂肪食物,每次都调用大量胰岛素
最后就使全身细胞对胰岛素不敏感,产生insulin resistance
改善insulin resistance最佳的方法,就是运动,确切地说,有氧运动。 |

r****y 发帖数: 178 | 8 试着写一下关于backpacking帐篷的选择
backpacking的帐篷最主要的因素有
防水性,这个一目了然
UV-resistent,可以延长使用寿命
重量,越轻越好,还有pcaked size越小越好
搭建方式,有所谓的quick pitching和传统的两步走
还有就是用途,比如alpine,4 season,3 season...
出口个数,储藏空间(就是里子和皮之间可以放gear的那部分)
帐篷表皮的材料很重要,好的要具有uv-resistent,防水性,轻便,和防撕裂
UV-resistant是靠一层coating,可以延长使用寿命,也防止表皮变脆弱
防水性主要以水头来体现,最高大概可以承受3500毫米水头
一般的也应该承受1500毫米,还有就是seam sealed所有针眼,并且用tape粘住
防撕裂(rip stop)就是如果破了个洞,就是一个洞,而不会撕裂开来
另外floor一般是tub floor,也是seam sealed,并且应该耐磨
在美国看到的帐篷,感觉floor比较薄弱,还要另买footprint,给搭建增加工作
另外pole和钉子也是增加重量的因素, |

The point is: when you move from movement1 to movement2, especially in
making certain types of turns, your body should first resists to move by
going to the opposite direction, and then quickly makes movement2 (the
resistance gives you the momentum to move faster).
