Abstract

Current fiber intakes are alarmingly low, with long-term implications for public health related to risk of coronary heart disease, stroke, hypertension, certain gastrointestinal disorders, obesity, and the continuum of metabolic dysfunctions including prediabetes and type 2 diabetes. Eating patterns high in certain fibers are known to lower LDL cholesterol and blood pressure, lower blood glucose, and decrease insulin resistance in people with prediabetes and type 2 diabetes; help with both weight loss and maintenance; and improve bowel regularity and gastrointestinal health. With >90% of adults and children who fall short of meeting their daily fiber recommendations, the 2010 Dietary Guidelines for Americans once again classified fiber as a nutrient of concern. Despite efforts over the past decade to promote adequate fiber through fruit, vegetable, and whole-grain intakes, fiber consumption has remained flat at approximately half the daily recommended amount. The public health implications of inadequate fiber intake prompted the roundtable session "Filling America's Fiber Gap: Probing Realistic Solutions," which assembled nutrition researchers, educators, and communicators to identify challenges, opportunities, and realistic solutions to help fill the current fiber gap. The roundtable discussions highlighted the need for both consumer and professional education to improve acceptance for and inclusion of grain-based foods with added fiber as one strategy for increasing fiber intakes within daily energy goals.

摘要

目前的纤维摄入量低得惊人,这对公众健康有长期影响,与冠心病、中风、高血压、某些胃肠道疾病、肥胖以及包括糖尿病前期和 2 型糖尿病在内的代谢功能障碍的连续体有关。已知某些纤维含量高的饮食模式可降低 LDL 胆固醇和血压,降低血糖,降低糖尿病前期和 2 型糖尿病患者的胰岛素抵抗;有助于减肥和维持体重;并改善肠道规律性和胃肠道健康。超过 90%的成年人和儿童未能达到每日纤维推荐摄入量,因此 2010 年美国人饮食指南再次将纤维列为关注的营养素。尽管在过去十年中,通过增加水果、蔬菜和全谷物的摄入量来促进足够的纤维摄入,但纤维的摄入量仍然保持在每天推荐量的一半左右。纤维摄入不足对公众健康的影响促使“填补美国纤维缺口:探究切实可行的解决方案”专题小组会议召开,该会议召集了营养研究人员、教育工作者和传播者,以确定挑战、机遇和切实可行的解决方案,帮助填补当前的纤维缺口。专题小组讨论强调了消费者和专业教育的必要性,以提高对添加纤维的谷物类食品的接受度和包含度,这是在每日能量目标内增加纤维摄入量的一种策略。
