Advances in Whole Grain Phytochemicals and Health Research

摘要

尽管目前已普遍认同增加全谷物以及全谷物产品的消费可以降低大部分慢性病的患病风险,包括心血管疾病、Ⅱ型糖尿病和某些癌症,但是全谷物中的植物化学素以及其发挥的抗氧化作用并没有像蔬菜和水果中的植物化学素那样受到同样的重视.近来的研究显示,以往的文献报道低估了全谷物中所含的总的植物化学素的含量和其发挥的抗氧化活性.大多数全谷物中的酚类物质以结合态形式存在,如玉米中有85％、小麦中有76％、燕麦中有75％、稻米中有62％的酚类物质是以结合态的形式存在的,而以往文献报道的大多是游离态酚酸的含量.%Phytochemicals and antioxidants in whole grains have not received as much attention as the phytochemicals in fruits and vegetables although the increased consumption of whole grains and whole grain products has been associated with reduced risk of developing chronic diseases such as cardiovascular disease,type 2 diabetes,some cancers and all-cause mortality.Recent research has shown that the total phytochemical content and antioxidant activity of whole grains have been commonly underestimated in the past literature,and that whole grains contain more phytochemicals than that previously reported.
