由行政院衛生署的資料統計，國人十大死因中有七項為慢性疾病，而且有年輕化的趨勢，國人的飲食出現營養不均衡的問題。基於此種現況，消費者開始體認到健康飲食的重要性，因此坊間標榜著健康概念的蔬食產品越來越多，蔬食飲食的風潮亦逐漸盛行。聯合國呼籲大家，改變飲食習慣，轉為朝向無肉無奶無蛋的植物性飲食，否則無法因應2050 年時人類人口和生態的改變。有鑑於蔬食產品的日益重要性，本研究欲從消費者的角度來瞭解消費者選擇蔬食產品的意願調查及行為分析。
首先整理出蔬食定義與台灣地區蔬食產業概況，並以計畫行為理論為本研究核心，進而設定出研究假說。
其二，回收有效問卷共350份進行樣本的分析，藉由深入探討消費者對於蔬食消費的態度、主觀規範及行為控制知覺，了解蔬食產品消費意願之關鍵因素。
最後，關於消費蔬食經驗的有無，蔬食消費的態度、主觀規範以及行為控制知覺對蔬食消費意願的看法。在進行樣本資料實證分析之後，本研究主要的研究結果如下：
1. 民眾對蔬食消費的態度對蔬食消費意願有顯著正向關係。
2. 民眾對蔬食消費的主觀規範對蔬食消費意願有顯著正向關係。
3. 民眾對蔬食消費的行為控制知覺對蔬食消費意願有顯著正向關係。
4. 個人背景變數在蔬食消費意願有顯著性差異。
