Single vegetable meal content equivalence and alternative to fat for satiety : a randomised trial in Japanese women

Background: 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: In a randomized crossover design, 40 young Japanese women consumed controland 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 propertiesbefore 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 withcontrol 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.
