Resveratrol and Raisins
According to the California Raisin Marketing Board, California raisins are
made from seedless green grapes and don't contain significant amounts of
resveratrol. The sun-drying process of raisins also reduces resveratrol
content due to oxidation, although raisins cured indoors maintain higher
levels. A review in the "Journal of Food Chemistry" in January 2010 reported

看防嗮成分
物理成分一般都是titanium dioxide或者zinc oxide
化学防晒成分很多,
很多防晒系数高的都是物理化学混合的
由于物理的防晒成分的限制做成液体喷的少
一般情况下喷的都说化学防晒成分
我一般都用露得清粉色一款baby的60+,我个人用觉得非常好,全物理防晒,虽然涂抹
之后白白的略油,但是我觉得还能防止防晒而且还防止晒黑

这次巴黎气候大会的意义是非常重大的,过两天在股市上就会反映出来。
他解决了全球气候变化的合法性问题,即使是伪科学,政治阴谋,
但是200多个国家在这个协议上签字,立法了。(尽管他们通过协议,我还是
认为这主要是阴谋, 是伪科学,没有足够的证据支撑他们的结论。)
世界上的大国,中国,美国,英国,法国,俄国等全都签字画押了。
这比1997年的控制温室气体的《京都议定书》要进了一大步,那次美国人
放鸽子了。这次,欧美一体了。
中国的媒体不分析,不跟踪,不比较,有很多原因,这不能证明我的分析就是
错误的。当然,我也不能保证我的分析是正确的,我只是把自己跟踪这个问题很多年
的一些观察和思考share给你一下而已。
你要觉得没用,可以不要看,不要浪费时间在上面!
合法化的问题解决之后, 减排的目标确定之后, 下面就是具体实施的问题了。
方向已经指明了, 二氧化碳税就是怎么征收,管理和交易的问题了。

has a pH of about 4.3.
