素食减肥反增重？这些"健康素菜"竟是隐形油脂炸弹！

Core Viewpoint - The article highlights the misconception that vegetarian diets are inherently low in calories and beneficial for weight loss, revealing that many seemingly healthy vegetarian dishes can actually lead to excessive fat intake due to their high oil absorption rates during cooking [5][8][18]. Group 1: Understanding Oil Absorption - The concept of "oil absorption rate" is introduced, defined as the percentage of oil absorbed by vegetables during cooking, calculated using the formula: (post-cooking oil amount - pre-cooking oil amount) / total oil used × 100% [9]. - Certain vegetables, such as eggplants, mushrooms, and root vegetables, are identified as having high oil absorption rates, with eggplants absorbing up to 37% of oil when fried [12][18]. Group 2: Cooking Techniques and Recommendations - Recommended cooking methods to minimize oil absorption include steaming, boiling, and cold mixing, which preserve the original flavor of the ingredients while reducing additional oil intake [14]. - Specific pre-treatment techniques for high oil-absorbing vegetables, such as steaming or blanching before frying, can significantly reduce oil absorption by over 50% [15][19]. Group 3: Common Misconceptions and Dietary Advice - The article addresses common misconceptions about vegetarian diets, emphasizing that not all vegetarian foods are low in calories and that high-temperature cooking methods like frying can lead to increased oil absorption [18]. - It encourages a balanced approach to cooking, suggesting the use of spices and herbs to enhance flavor without relying on excessive oil, thus promoting healthier eating habits [19].
