蛋白质和膳食纤维在帮助产生持久饱腹感方面效果相当1。然而，澳大利亚人的营养摄入现状存在明显失衡。根据2023年全国营养与身体活动调查，澳大利亚女性平均蛋白质摄入78.7克/天，男性103.4克/天，均已超过推荐摄入量——女性46克/天、男性64克/天1。相比之下，膳食纤维摄入则严重不足，女性平均摄入19.2克/天、男性22.3克/天，分别低于推荐的25克/天和30克/天1。
鉴于澳大利亚人膳食纤维摄入普遍低于建议水平，增加纤维素摄入对整体健康更具益处1。若要获得额外的健康收益，女性需摄入28克/天、男性需摄入38克/天的膳食纤维1。
Both protein and dietary fiber prove equally effective at producing lasting feelings of fullness, according to research examined in a nutritional analysis 1. However, the nutritional profiles of Australians reveal a stark imbalance in how these two nutrients are being consumed.
Australian adults are already exceeding recommended protein intake levels, while simultaneously falling short on fiber consumption 1. Women aged 19 to 70 should consume 46 grams of protein daily, and men 64 grams 1, yet 2023 national nutrition data shows Australian women average 78.7 grams per day and men 103.4 grams 1. In contrast, women require 25 grams of daily dietary fiber and men 30 grams to meet basic recommendations, with 28 grams for women and 38 grams for men needed to achieve additional health benefits 1. Current intake falls short of even these baseline targets: Australian women consume an average of 19.2 grams of fiber daily, while men consume 22.3 grams 1.
Given that Australians are already consuming adequate protein but remain significantly deficient in fiber intake, increasing fiber consumption offers greater overall health advantages than prioritizing additional protein 1.
