对８１５名购销保健食品人员进行知识─态度─行为（Ｋ－Ａ－Ｐ）的问卷调查结果表明：人们的营养及保健食品知识水平（简称知识水平）与文化程度呈正相关（ｒ＝０．９６，Ｐ＜０．０１），人们对保健食品的态度是积极或较积极的，７４．９％的人选用保健食品时主要考虑功能。但家庭主妇、个体经营者、工人知识水平较低，销售与购买保健食品人员的知识水平无显著性差异（ｔ＝１．３９，Ｐ＞０．０５），上述人群应为营养教育的重点对象，被调查者中有１０％～５０％的人不能正确选择含各种营养素的食品，４４．５％的人认为保健食品是食品，更有少数人认为应按医生处方食用保健食品，食用保健食品的目的是治疗疾病。提示应尽快明确保健食品概念、普及营养及保健知识，澄清人们的认识，营养教育以选择电视、广播、报纸和杂志等形式为主。
