摘要


背景与目的:虽然高能量密度食物非常可口,由于脂肪含量高,过度消费会导致肥胖。低能量密度的食物是防止个人超重的更有效方法。我们研究了不同数量的单一蔬菜如何影响不同能量密度食物的感官特性。方法与研究设计:在一项随机交叉设计中,40名年轻的日本妇女摄入正常或高脂肪(HF)午餐。正常饮食含有相同量的米饭和汉堡和80克(C80),120克(C120),160克(C160),200克(C200)、240克(C240)或280克(C280)西兰花。HF 控制餐为添加了38.1克食用油(HF80、HF120、HF 160、HF200、HF240 和HF280)。使用视觉模拟量表评估摄入前及摄入后0.5、1、2、3、4和5 小时后的感官特性。结果:与0.5h的C200和C280相比以及所有时间点相比,C80饱腹感明显低。相比之下,各个时间点所有的HF膳食的满意度均相似。与对照组相比,HF膳食组的饱腹感和满意度更高。然而,HF200膳食组和摄食1-4h后对照组的饱腹感和满意度相似。结论:当膳食中只有单一蔬菜时,脂肪能增加饱腹感;然而,500 卡路里低脂肪膳食中至少含有200克蔬菜时,饱腹感和满意度与单纯HF膳食相似。

Background and Objectives: Although high energy density foods are highly palatable, their overconsumption leads to obesity because of high fat content. Low energy density foods are more effective for preventing individuals from becoming overweight. We investigated how different amounts of a single vegetable affect the sensory properties of meals with different energy densities. Methods and Study Design: In a randomized crossover design, 40 young Japanese women consumed control and high-fat (HF) lunches. Control meals contained the same amount of rice and hamburger and 80 g (C80), 120 g (C120), 160 g (C160), 200 g (C200), 240 g (C240), or 280 g (C280) of broccoli. HF meals were control meals to which 38.1 g of oil was added (HF80, HF120, HF160, HF200, HF240, and HF280). Sensory properties before intake and 0.5, 1, 2, 3, 4, and 5 h after meals were assessed using a visual analog scale. Results: Fullness was significantly lower with C80 than with C200 and C280 at 0.5 h and all time points, respectively, after consumption. In contrast, satisfaction with all HF meals was similar at all time points. Fullness and satisfaction were higher with almost all HF meals than with control meals; however, fullness and satisfaction were similar between HF200 and all control meals 1-4 h after consumption. Conclusions: Fat increases satiety when a single vegetable is included in the meal; however, at least of 200 g of vegetable in a 500- kcal meal with low fat content provides fullness and satisfaction similar to those provided by an HF meal.
