Health Food Truths

“低碳水化合物”的意大利面是健康食品的一种,这在业内被称作“较小的恶”—含有较少的热量、脂肪、反式脂肪、糖、盐或碳水化合物。这种食品及那些被归类为“天然”、“有机”和“功能性”的食品现在已成为了一个完整的产业。但它们真的更有利于你的健康么?

在美国,“有机”是由农业部赋予了确切的定义。然而,“天然”则是食品生产商或制造商们自己的说法。所谓的“功能性食品”—或“技术性食品”—则是那些由生产商加入了omega-3脂肪酸、人工甜味剂、抗性淀粉(indigestible starches)、降胆固醇剂、大豆或奶(麦)蛋白、植化素(phytochemicals)和其他成分从而能够充分发挥美国食品与药物管理局(FDA)所允许的“合格”健益特性。

近年来,“较小恶”和功能性食品的销售一片风光,2004年在美国的销售额达到了850亿美元。如果你经常性地购买这类食品,你就是“乐活族”消费者—健康食品业最为珍视的顾客群体。你购买低碳水化合物产品、能量和营养条、强化维他命和矿物质的食品和饮料、大豆食品和几乎任何具有健益特点的食品。

    Angela Merkel’s Endgame?

    The collapse of coalition negotiations has left German Chancellor Angela Merkel facing a stark choice between forming a minority government or calling for a new election. But would a minority government necessarily be as bad as Germans have traditionally thought?

    Preparing for the Trump Trade Wars

    In the first 11 months of his presidency, Donald Trump has failed to back up his words – or tweets – with action on a variety of fronts. But the rest of the world's governments, and particularly those in Asia and Europe, would be mistaken to assume that he won't follow through on his promised "America First" trade agenda.

    The Platform Economy

    While developed countries in Europe, North America, and Asia are rapidly aging, emerging economies are predominantly youthful. Nigerian, Indonesian, and Vietnamese young people will shape global work trends at an increasingly rapid pace, bringing to bear their experience in dynamic informal markets on a tech-enabled gig economy.

    Profiles in Discouragement

    One day, the United States will turn the page on Donald Trump. But, as Americans prepare to observe their Thanksgiving holiday, they should reflect that their country's culture and global standing will never recover fully from the wounds that his presidency is inflicting on them.

    How Women Shape Coups

    In Zimbabwe, as in all coups, much behind-the-scenes plotting continues to take place in the aftermath of the military's overthrow of President Robert Mugabe. But who the eventual winners and losers are may depend, among other things, on the gender of the plotters.

    The Abnormality of Oil

    At the 2017 Abu Dhabi Petroleum Exhibition and Conference, the consensus among industry executives was that oil prices will still be around $60 per barrel in November 2018. But there is evidence to suggest that the uptick in global growth and developments in Saudi Arabia will push the price as high as $80 in the meantime.

    The Saudi Prince’s Dangerous War Games

    Saudi Arabia’s Crown Prince Mohammed bin Salman is working hard to consolidate power and establish his country as the Middle East’s only hegemon. But his efforts – which include an attempt to trigger a war between Israel and Hezbollah in Lebanon – increasingly look like the work of an immature gambler.
