美国人的饮食中有几种营养素不足，但纤维缺乏是最严重的。几乎所有的美国人都没有达到每日纤维的建议，平均错过了近一半的目标摄入量。鉴于纤维在促进健康和降低疾病风险方面的既定作用，这种惊人的低摄入量对公共卫生具有重要意义。尽管人们努力促进更多的水果、蔬菜、豆类和全谷物的摄入，但纤维缺乏仍然存在。然而，这些方法还需要解决能量平衡和过度消耗卡路里的问题。正如本系列第1部分和第2部分所报道的那样，全谷物在膳食指南中被定位为纤维的重要来源，消费者选择这些食物的期望是获得良好的纤维来源，但全谷物产品中的纤维含量可能差异很大。本文将探讨添加到食物中的纤维作为补充策略的作用，以帮助提高总纤维的摄入量，而不增加不必要的卡路里。[See第2部分FSTA 2012-09-Ma 3101。]
There are several nutrients found to be inadequate in the American diet, but fiber deficit is one of worst. Nearly all Americans fall short in meeting daily fiber recommendations, on average missing target intakes by nearly one-half. This alarmingly low intake has important implications for public health, given the established role of fiber in health promotion and disease risk reduction. The fiber deficit persists despite efforts to promote greater intakes of fruits, vegetables, legumes, and whole grains. However, these approaches also need to address energy balance and the problem of over-consumption of calories. As reported in parts 1 and 2 of this series, whole grains are positioned in dietary guidance as an important source of fiber, and consumers are choosing these foods with the expectation of getting a good source of fiber, yet the amount of fiber in whole-grain products can vary widely. This article will explore the role of fiber added to food as a complementary tactic to help improve intakes of total fiber without adding unnecessary calories. [See FSTA 2012-09-Ma3101 for Part 2.]
