Anecdotal evidence exists that the public is becoming skeptical about nutrition messages. This article examines whether there is a backlash against dietary recommendations and whether it is associated with less healthful diets.
DESIGN/PARTICIPANTS: Data are from a 1997-1998 Washington State random-digit-dial survey of 1,751 adults designed to monitor attitudes and behavior related to cancer risk and prevention.
Responses to the nutrition backlash survey were weighted to reflect the Washington State population. Linear regression was used to examine associations of nutrition backlash with fat and fruit and vegetable intake.
This survey did not find strong evidence that nutrition backlash was widespread. However, 70% of respondents thought that Americans are obsessed with the fat in their diet and that the government should not tell people what to eat. More than a quarter agreed with the statement that eating low-fat foods takes the pleasure out of eating. Nutrition backlash was associated with less healthful diets: individuals showing high backlash had a fat-related diet habits score of 2.11 compared with a score of 1.73 among those showing low backlash (P for trend = .001), which corresponds to a difference of roughly 4 percentage points in percentage energy from fat. Individuals showing high backlash reported eating only 2.72 servings of fruits and vegetables per day, compared with 3.35 servings among those showing low backlash (P for trend = .001).
APPLICATIONS/CONCLUSIONS: Nutrition professionals need to ensure that dietary recommendations are clear and positive to avoid the possibility that consumers may disregard nutrition messages entirely.
有传闻证据表明公众对营养信息正持怀疑态度。本文探讨是否存在对饮食建议的抵制,以及这是否与不健康饮食相关。
设计/参与者:数据来自1997 - 1998年华盛顿州对1751名成年人的随机数字拨号调查,旨在监测与癌症风险和预防相关的态度及行为。
对营养抵制调查的回复进行加权以反映华盛顿州人口情况。采用线性回归分析营养抵制与脂肪及水果和蔬菜摄入量之间的关联。
本次调查未发现有力证据表明营养抵制现象普遍存在。然而,70%的受访者认为美国人对饮食中的脂肪过于关注,且政府不应告诉人们该吃什么。超过四分之一的人认同“吃低脂食物会让饮食失去乐趣”这一说法。营养抵制与不健康饮食相关:表现出高抵制的个体与脂肪相关的饮食习惯得分为2.11,而低抵制者的得分是1.73(趋势P值 = 0.001),这相当于来自脂肪的能量百分比相差约4个百分点。表现出高抵制的个体报告称每天仅食用2.72份水果和蔬菜,而低抵制者为3.35份(趋势P值 = 0.001)。
应用/结论:营养专业人员需确保饮食建议清晰且积极,以避免消费者可能完全无视营养信息的情况。
