This study was undertaken to provide evidence of the variation in the diet necessary to incorporate a high fibre content. Food intakes were measured for seven days by 51 subjects who were either omnivores, vegetarians or vegans. Omnivores consumed the least fibre (23 g), vegetarians significantly more (37 g) and vegans the most (47 g). Men had higher intakes (44 g) than women (30.5 g). Vegans ate the most cereal fibre, but high intake of fibre by both vegetarian groups were due to their preference for unrefined foods, particularly bread. Higher intakes of vegetable fibre by both vegetarian groups were due to high consumption of pulses. Total dietary fibre was significantly related to cereal fibre. As the percentage of fibre increased, the percentage of energy derived from protein decreased. Fat contributed less energy (34 per cent) to the vegan than to the omnivore diet (41 per cent). This study showed that high fibre intake can be achieved on an omnivorous diet and the observation that high fibre diets are possible when the energy content is low, is of relevance to slimming regimes.
本研究旨在提供证据，证明为摄入高纤维含量所需饮食的差异。51名受试者（包括杂食者、素食者或纯素食者）进行了为期七天的食物摄入量测量。杂食者摄入的纤维最少（23克），素食者显著更多（37克），纯素食者最多（47克）。男性摄入量（44克）高于女性（30.5克）。纯素食者摄入的谷物纤维最多，但两个素食群体的高纤维摄入量都归因于他们对未精制食物的偏好，尤其是面包。两个素食群体较高的蔬菜纤维摄入量归因于豆类的高消费量。总膳食纤维与谷物纤维显著相关。随着纤维百分比的增加，蛋白质提供的能量百分比下降。与杂食者饮食（41%）相比，脂肪为纯素食者提供的能量较少（34%）。这项研究表明，杂食性饮食也可以实现高纤维摄入，而且当能量含量较低时高纤维饮食是可行的这一观察结果与减肥方案相关。
