本研究的主要目的在探討3項主題：（1）臺北市內湖區中年族群的飲食綠色消費知識與行為之現況；（2）不同背景的中年族群知識或行為的差異情形；（3）分析知識與行為之間的相關性。本研究對象為內湖區年齡介於45歲至64歲中年族群，研究方法採用便利抽樣方式蒐集樣本，共發放450份問卷，有效問卷為390份，研究數據運用SPSS 20.0統計軟體，進行統計分析。研究結果顯示女性的飲食綠色消費知識及行為得分均高於男性，年輕中年族群（45－49歲）的知識得分優於高年齡（60－64歲）族群。在職業變項方面，「軍公教職人員」的知識得分高於「商業人士」，而「軍公教職人員」與「其他職業」族群行為得分均優於「運輸及通訊業人士」。另外，月零用錢多寡對知識或行為皆無顯著差異性。具有「研究所以上」學歷族群的知識得分顯著高於「國中（含）以下」學歷者，但在行為方面則沒有顯著差異性。實行綠色飲食生活模式愈久的族群，其飲食綠色消費行為愈正確。本研究結果發現飲食綠色消費知識與行為具有低度正相關（Pearson係數=0.177）。綜合以上結果，政府應該加強飲食綠色消費知識的宣導，尤其是年齡較老的男性族群，以及從事「商業」及「運輸及通訊業」的中年人士，以促進民眾實施飲食綠色消費生活。
