营养流行病学依赖于对个体暴露于食源性因素的有效评估。所使用的工具通常是钝的仪器，便于科学家管理和分析。收集食物、组合数量、提取情景记忆或一般记忆以及解释问题的负担都落在了受试者身上。替代方法包括加强使用暴露的生物标志物作为外部、内部和靶组织标志物。由于生物标志物仅存在于感兴趣的暴露时间的少数感兴趣的物质中，因此主观测量的未来可能是应用现代技术开发主观饮食评估方法，包括音频系统以克服识字障碍并允许多语言采访，以及用于识别食物的图片。自动化方法可以确保所有问题都已得到答复，并且所有超出正常范围的答复都已经过双重检查。计算机辅助自我访谈（CASI）可能被证明是最经济和认知支持的方法，在未来的评估食源性暴露。
Nutritional epidemiology depends on valid assessment of exposure of individuals to food-borne factors. The tools being applied are generally blunt instruments that are simple for the scientist to administer and analyze. The burden of aggregating foods, combining amounts, drawing on episodic or generic memory, and interpreting the questions is placed on the subjects. Alternative approaches include enhanced use of biomarkers of exposure as external, internal, and target tissue markers. Because biomarkers exist for only a few substances of interest at the exposure time of interest, the future of subjective measures is likely to be in the development of subjective dietary assessment methods that apply modern technology, including audio systems to overcome literacy barriers and allow multilingual interviews, and pictures for identifying foods. Automated methods can ensure that all questions have been responded to and all responses outside of normal ranges have been double-checked. Computer-assisted self-interviewing (CASI) may prove to be the most economic and cognitively supportive approach for assessment of food-borne exposures in the future.
