今天在#SciAmBlogs这里是美食日,尽管我没有参与,但网络上有很多值得阅读的精彩帖子。你可以在这里阅读Bora的链接汇总。我最喜欢的一些是:

“人 vs. 食物”之地的食物浪费,作者:David Wogan。“工业化国家消费者层面的食物浪费(2.22亿吨)几乎与撒哈拉以南非洲的食物净产量总和(2.3亿吨)一样高。”美国生产的近一半可食用食物从未被食用。

人如其食,作者:Razib Khan。生物学影响文化,文化影响生物学。农业和畜牧业改变了我们吃什么和怎么吃,但我们的消化生理也必须适应处理小麦和乳制品等食物。

益生菌如何拯救您的生命,作者:Rob Dunn。人们认为益生菌有助于治疗许多消化疾病,但支持这些说法的实际数据很少,而且它们可能如何运作的生理机制仍然未知。然而,最近在小鼠身上进行的研究表明,一种益生菌菌株如何能在肠道中胜过有害的幽门螺旋杆菌的潜在机制。

胡萝卜能帮助你看得更清楚吗?不,但巧克力可能会,作者:Cheryl Murphy。实验数据表明,黑巧克力中的黄烷醇可以提高视力和认知能力。我下周也会发布一篇关于巧克力的文章。:)

有机蜂蜜是一个甜蜜的错觉,作者:Alex Wild。“超市里一罐标准的蜂蜜需要蜜蜂进行一百万次访花。一个蜂群每年可能生产 50 到 100 罐这样的蜂蜜。” 由于蜂蜜的生产需要如此多的花朵,蜜蜂在寻找花蜜时经常会偏离蜂巢 5 公里,当资源稀缺时,它们的半径可能会翻倍。许多有机农民无法控制蜂巢如此大半径范围内的农药使用。

"Life creates [the Force], makes it grow. Its energy surrounds us and binds us. Luminous beings are we, not this crude matter," Yoda explains in The Empire Strikes Back, gesturing to Luke's physical body. This quote is striking because of the apt juxtaposition of the wonder of life with its often disgusting vessel. Like many other animals, we secrete, excrete, expectorate, defecate, flatulate, regurgitate, urinate, circulate, masticate, menstruate, ejaculate, and ventilate. We are filled with gas and feces and blood and guts and mucus and any number of rude things. Life as we know it is possible because of the countless impolite things we do every day. Are we luminous beings? Perhaps, but that's neither here nor there. This blog is about the crude matter that keeps us alive.
