There not only seems to be a trend for people to underestimate the dietary risks that they face, but it appears that this underestimation may be related to the difficulties they encounter when trying to assess their own dietary intake. A study (n = 118) examining the effects of providing people with information about their own dietary fat intake on their attitudes towards dietary change and their subsequent fat consumption is described. Participants in a group receiving feedback about their fat intake did not decrease their consumption of fat more than did those in a control group. No effects on subsequent fat consumption were observed in a group who had higher than average levels of fat consumption, higher perceived fat consumption than actual fat consumption and who received feedback information about their fat consumption. The results are discussed in relation to their implications for health promotion strategies that focus on the motivational effects of providing people with information about their fat consumption.
人们似乎不仅有低估自身所面临饮食风险的趋势，而且这种低估似乎可能与他们在尝试评估自己的饮食摄入量时遇到的困难有关。本文描述了一项研究（n = 118），该研究考察了向人们提供有关其自身膳食脂肪摄入量的信息对他们对饮食变化的态度以及随后的脂肪摄入量的影响。接受脂肪摄入量反馈的一组参与者，其脂肪摄入量的减少幅度并不比对照组更大。在脂肪摄入量高于平均水平、感知到的脂肪摄入量高于实际脂肪摄入量且收到关于其脂肪摄入量反馈信息的一组中，未观察到对随后脂肪摄入量有影响。本文讨论了这些结果对健康促进策略的意义，这些策略侧重于向人们提供有关其脂肪摄入量信息的激励作用。
