1.超级食物(Superfoods):什么是超级食物?影片对于此貌似没有严格的定义,为此我查了维基百科上对于Superfood的定义:
“Superfood is a term sometimes used to describe food with high phytonutrient content that may confer health benefits as a result. For example, blueberries are often considered a superfood (or superfruit) because they contain significant amounts of antioxidants, anthocyanins, vitamin C, manganese, and dietary fiber.
The term is not in common currency amongst dieticians and nutritional scientists, many of whom dispute the claims made that consuming particular foodstuffs can have a health benefit.There is no legal definition of the term and it has been alleged that this has led to it being over-used as a marketing tool“
石榴汁是其中一种超级食物。研究发现石榴汁可以明显放缓前列腺癌的扩散,但是这些研究的资料仅来源于一项小规模的癌症研究,而且此研究对比的是喝了石榴汁后前列腺癌患者的生存率,不是拿石榴汁和苹果汁或洋葱汁等进行比较,甚至没有和抗癌药进行对比。最值得注意的是,为该研究提供资金的是一家生产石榴汁的公司。目前没有任何科学研究可以证明超级食品比普通食品更有益处。
对于上述问题,我们进行了一些启迪的研究。5对双胞胎在未来的三周内摄取不同的食物,其中一位摄取普通水果和蔬菜,另一位则摄取超级食品,最终的结果表明双胞胎血液内维生素和矿物质的含量变化似乎是随机的,且和是否摄取了超级或普通食品毫无关联。很多指标不升反降,其中包括超级食品中富含的维生素C。实验室里的超级食品,进入人体后未必还是超级食品。我们的身体有自己的运作规律,我们不能指望食品解决一切问题。
