This article presents findings from three separate data sets on food consumption in apparently healthy Malaysian adult males and females aged 22-60 years, and secondary data extracted from the Malaysian Adult Nutrition Survey (MANS) 2003. Assessment of food intake by 24-hour recall or the food diary method and use of the nutrient calculator- DietPLUS- to quantify intake of macronutrients and dietary fibre (DF) in the primary data, revealed low mean DF intakes of 10.7±1.0 g/day (Course participants, n=52), 15.6 ±1.2 (University sample, n=103), and 16.1±6.1 (Research Institute staff, n=25). An alarmingly high proportion of subjects (75 to 95%) in these three data sets did not meet the national population intake goal of 20-30 g DF/day. A list of 39 food items which contain fibre, extracted from the MANS 2003 report as being average amounts consumed daily by each Malaysian adult, provided 19.2 g DF which meant that >50% of Malaysian adults consumed less than the recommended DF intake of 20-30 g/day. This large deficit of actual intake versus recommended intakes is not new and is also observed in developed western nations. What is of great concern is that the preliminary findings presented in this article indicate that the national population goal of 20-30 g DF/day may be beyond the habitual diets of the majority of Malaysians. Appropriately, the authors propose the inclusion of a daily minimum requirement for DF intake in the Malaysian Dietary Guidelines, which would somewhat mimic the Malaysian Dietary Guidelines 1999 for dietary fat, as well as the stand taken by the Scientific Advisory Committee on Nutrition (SACN) of the United Kingdom. This minimum requirement, if agreed to, should not be higher than the 16 g DF or so provided by the hypothetical 'high-fibre' healthy diet exemplified in this article.
本文展示了来自三个独立数据集的研究结果,这些数据集涉及年龄在22至60岁之间、看似健康的马来西亚成年男性和女性的食物消费情况,以及从2003年马来西亚成人营养调查(MANS)中提取的二手数据。通过24小时回忆法或食物日记法评估食物摄入量,并使用营养计算器——DietPLUS——来量化原始数据中常量营养素和膳食纤维(DF)的摄入量,结果显示平均DF摄入量较低,分别为10.7±1.0克/天(课程参与者,n = 52)、15.6±1.2(大学样本,n = 103)和16.1±6.1(研究所工作人员,n = 25)。在这三个数据集中,令人震惊的是,高达75%至95%的受试者未达到国家人口每天摄入20 - 30克DF的目标。从2003年MANS报告中提取的一份包含纤维的39种食物清单,这些食物是马来西亚成年人每日平均消费量,提供了19.2克DF,这意味着超过50%的马来西亚成年人的DF摄入量低于建议的20 - 30克/天。实际摄入量与建议摄入量之间的这种巨大差距并非新鲜事,在西方发达国家也有观察到。非常令人担忧的是,本文提出的初步研究结果表明,国家人口每天摄入20 - 30克DF的目标可能超出了大多数马来西亚人的习惯饮食。相应地,作者建议在马来西亚饮食指南中纳入DF摄入的每日最低要求,这在一定程度上类似于1999年马来西亚饮食指南中对膳食脂肪的规定,以及英国营养科学咨询委员会(SACN)的立场。如果这一最低要求获得通过,不应高于本文中假设的“高纤维”健康饮食所提供的约16克DF。
