英文文献作者：Lin, Biing-Hwan,Yen, Steven T.
英文文献摘要：
Responding to mounting evidence of the association between whole-grain consumption and a reduced risk of heart problems and other diseases as well as body weight maintenance, the U.S. Government has strongly encouraged its citizens to increase consumption of whole grains. However, compared against the 2005 Federal dietary recommendations, in 1994-96 only 6 percent of Americans met the current recommended whole-grain consumption. To narrow this huge gap between actual and recommended consumption of whole grains, an effective nutrition education campaign is needed. A demand system with two censored consumption equations and two endogenous knowledge and attitude variables is estimated to investigate the factors that affect the consumption of whole and refined grains. The results can be used to help develop an effective education campaign in promoting consumption of whole grains in Americans' diets.
越来越多的证据表明，食用全谷物与降低心脏病和其他疾病的风险以及保持体重之间存在关联，为此，美国政府大力鼓励国民增加食用全谷物。然而，与2005年联邦饮食建议相比，1994- 1996年只有6%的美国人达到了目前推荐的全谷物摄入量。为了缩小全谷物实际消费量和推荐消费量之间的巨大差距，需要开展有效的营养教育活动。摘要以两个删尾消费方程和两个内生知识和态度变量作为需求系统，研究了影响全粮和精粮消费的因素。研究结果可以用来帮助发展一项有效的教育运动，以促进美国人饮食中全谷类的消费。
