Up-to-date information is unavailable on intakes of non-starch polysaccharide (NSP) in Britain. We surveyed 739 men aged 40-69 years and 976 women aged 25-69 years using a validated food-frequency questionnaire focused on carbohydrates. Mean NSP intake in the three decades of men was 15.5-16.4 g/day and in the five decades of women it was 14.3-15.3 g/day, with no clear effect of age. These NSP intakes are higher than those from a 1977 survey but well short of the recent government-recommended population mean of 18 g/day. However, nine people consumed over 32 g/day. The relative contribution of food groups to NSP intake varied with age and sex. Women obtained more NSP from raw fruit and salad, brown breads and breakfast cereals. Their preference for these foods probably explains why, overall, their NSP intakes were close to those of men. Younger people and men obtained relatively more of their NSP from potatoes cooked with fat and from pulses and less from raw fruit. The largest single source of soluble NSP was potatoes and half of this came from potatoes cooked with fat. In older women raw fruit and salad were equally important. Pulses provided about 10% of soluble NSP in younger women, cooked vegetables about 10% in older women. Increased potato consumption deserves attention as a means of obtaining the metabolic benefits of a high soluble NSP intake.
目前尚无英国非淀粉多糖（NSP）摄入量的最新信息。我们使用一份经过验证的、聚焦碳水化合物的食物频率问卷，对739名40 - 69岁的男性和976名25 - 69岁的女性进行了调查。男性三个年龄段的平均NSP摄入量为15.5 - 16.4克/天，女性五个年龄段的平均NSP摄入量为14.3 - 15.3克/天，年龄对其没有明显影响。这些NSP摄入量高于1977年调查的结果，但远低于近期政府建议的人群平均摄入量18克/天。然而，有9人每天的摄入量超过32克。不同食物组对NSP摄入量的相对贡献因年龄和性别而异。女性从生水果、沙拉、全麦面包和早餐谷物中获取的NSP更多。她们对这些食物的偏好可能解释了为什么总体上她们的NSP摄入量与男性接近。年轻人和男性从用脂肪烹制的土豆以及豆类中获取的NSP相对较多，从生水果中获取的相对较少。可溶性NSP的最大单一来源是土豆，其中一半来自用脂肪烹制的土豆。在老年女性中，生水果和沙拉同样重要。豆类在年轻女性的可溶性NSP中占比约10%，熟蔬菜在老年女性的可溶性NSP中占比约10%。增加土豆的消费量作为获取高可溶性NSP摄入量带来的代谢益处的一种方式值得关注。
