Functional foods are the fastest growing sector of the food market because of consumers growing interest in wellness, rapid advances in science and technology, increases in healthcare costs, changes in food laws affecting label and product claims, and an increase in the aging population.The purpose of this study was to explore functional food consumption behavior using social and behavioral theory, specifically Protection Motivation Theory (PMT).The effectiveness of the PMT was investigated through examining relationships among six constructs: severity, vulnerability, response-efficacy, self-efficacy, intention, and behavior.A self-selected convenience sample of 465 adults from a southwestern university in U.S.completed an online survey questionnaire.Results from structural equation modeling revealed that the PMT model had a good fit to the data (x2/df =2.02;CFI =.98;NNFI =.97;RMSEA =.05) to predict consumers functional food consumption behavior.Specifically,response-efficacy was a significant predictor of intention to eat functional foods but not of behavior.Self-efficacy was the only construct that significantly predicted intention as well as behavior.Outcomes of the study will be useful for health interventions to address healthy eating behavior for target population and context.

由于天然来源的微生物药物总存在一些这样那样的缺陷，由于人类生活环境与生活习惯的改变和病原微生物的进化，由于人类对健康长寿的要求有了明显的提高，对微生物药物的研究已经越来越注重于抗耐药菌药物、抗病毒药物、分子作用机理明确或作用靶位明确的药物、甚至是只用于治疗亚类群疾病的药物。因此，无论是现在还是未来再从自然界中找到一个疗效非常好的理想的"纯"微生物药物已经十分困难了。根据特定的模型筛选到的新活性化合
