Introduction: the Roux-en-Y gastric bypass (RYGB) is considered to be an efficient treatment of obesity. There is an improvement in the dietary intake in the immediate postoperative period, but after the first year there is a tendency to return to the old pre-surgery habits. The objective of the present study was to compare the dietary intake of women in the late postoperative period after RYGB with the recommendations of the specific bariatric food pyramid. Methodology: the whole population of patients submitted to RYGB being accompanied by two out-patients departments of the Complexo Hospital de Clínicas of Universidade Federal do Paraná in the period from March to September 2017 were considered, selecting only those who conformed to the inclusion criteria. The analyses carried out were: the hospital records, anthropometric evaluation, basal metabolic rate by indirect calorimetry, food consumption and questionnaires concerning physical activity, food intolerance and the dumping syndrome. The food consumption was separated into food groups in order to compare with the specific pyramid. Descriptive analyses were used to characterize the sample. Results: it can be seen that the percent of macronutrients in relation to the total energy value (TEV) was within the values established by the recommended dietary allowances (RDA), although with respect to fiber, 68% of the participants showed a consumption below the adequate intake (AI). Inadequacy was observed for practically all the components when comparing the number of portions per food group of the bariatric pyramid, with the exception of the protein group. Conclusion: after RYGB, the dietary consumption was compromised in quantity and quality. In addition, in the late postoperative period, women tended to choose high calorie dense foods poor in fiber, a fact that is aggravated by the presence of food intolerances.
Roux-en-Y胃旁路术（RYGB）被认为是治疗肥胖症的有效方法。术后短期内饮食摄入量有所改善，但术后一年后，患者有恢复术前饮食习惯的趋势。本研究的目的是比较RYGB术后晚期女性的饮食摄入量与特定减肥食物金字塔的建议摄入量。方法：研究对象为2017年3月至9月期间在巴拉那联邦大学临床综合医院两个门诊接受RYGB手术的所有患者，仅选择符合纳入标准的患者。进行的分析包括：医院记录、人体测量评估、间接测热法测定基础代谢率、食物消耗情况以及关于身体活动、食物不耐受和倾倒综合征的问卷调查。将食物消耗情况按食物类别分类，以便与特定金字塔进行比较。采用描述性分析对样本进行特征描述。结果：可以看出，与总能量值（TEV）相关的宏量营养素百分比在推荐膳食摄入量（RDA）规定的范围内，不过，就纤维而言，68%的参与者摄入量低于适宜摄入量（AI）。在比较减肥金字塔中每个食物类别的份数时，除蛋白质类别外，几乎所有成分的摄入量均不足。结论：RYGB术后，饮食消耗在数量和质量上均受到影响。此外，在术后晚期，女性倾向于选择纤维含量低、热量密度高的食物，食物不耐受的存在加剧了这一情况。
