背景：膳食多胺已被证明对人体多胺库有重要贡献。了解不同食物中多胺（腐胺、亚精胺和精胺）的含量以及日常食物选择对多胺摄入量的影响是有意义的，因为这些生物活性胺与健康和疾病有关。目的：与符合瑞典营养建议的饮食相比，估计青少年多胺摄入量和食物对这种摄入量的贡献。设计：对青少年膳食摄入量和“理想饮食”（瑞典营养建议客观化[SNO]）食物清单进行横断面研究，利用食物中多胺含量的数据库计算多胺摄入量。为了估计多胺摄入量，从93名青少年中收集的7天称重食物记录被输入饮食软件（Dietist XP），包括食物中多胺含量的数据。根据SNO推荐的食品中多胺的含量也以同样的方式输入。结果：青少年平均每日多胺摄入量为316 +/- 170 μ mol/d，而根据SNO计算的贡献值较高，平均多胺摄入量为541 μ mol/d。在青少年的摄入量和SNO中，水果贡献了近一半的总多胺摄入量。青少年摄取量低于SNO计算值的主要原因是青少年组蔬菜摄取量较少。结论：平均每日总多胺摄入量与之前在欧洲报道的相似。根据瑞典营养建议的“理想”饮食，这种生物活性非营养素的摄入量将高于我们的青少年报告的摄入量，也高于之前从欧洲报告的摄入量。
Background: Dietary polyamines have been shown to give a significant contribution to the body pool of polyamines. Knowing the levels of polyamines (putrescine, spermidine, and spermine) in different foods and the contribution of daily food choice to polyamine intake is of interest, due to the association of these bioactive amines to health and disease.Objective: To estimate polyamine intake and food contribution to this intake in adolescents compared to a diet fulfilling the Swedish Nutrition Recommendations.Design: A cross-sectional study of dietary intake in adolescents and an 'ideal diet' (Swedish nutrition recommendations objectified [SNO]) list of foods was used to compute polyamine intake using a database of polyamine contents of foods. For polyamine intake estimation, 7-day weighed food records collected from 93 adolescents were entered into dietetic software (Dietist XP) including data on polyamine contents of foods. The content of polyamines in foods recommended according to SNO was entered in the same way.Results: The adolescents' mean daily polyamine intake was 316 +/- 170 mu mol/day, while the calculated contribution according to SNO was considerably higher with an average polyamine intake of 541 mu mol/day. In both adolescent's intake and SNO, fruits contributed to almost half of the total polyamine intake. The reason why the intake among the adolescents was lower than the one calculated from SNO was mainly due to the low vegetable consumption in the adolescents group.Conclusions: The average daily total polyamine intake was similar to that previously reported in Europe. With an 'ideal' diet according to Swedish nutrition recommendations, the intake of this bioactive non-nutrient would be higher than that reported by our adolescents and also higher than that previously reported from Europe.
