Abstract

Objective

Individuals with chronic kidney disease (CKD) are at an increased risk for developing metabolic acidosis. Metabolic acidosis has been shown to worsen kidney function and exacerbate systemic inflammation. Diets high in protein foods can exacerbate metabolic acidosis as protein foods tend to be more acidic, while fruits and vegetables are more alkalotic. The main objective of this systematic review was to determine if higher consumption of fruits and vegetables in adults with CKD stages 1-5 reduces the rate of decline of estimated glomerular filtration rate.

Methods

Searches of Cumulated Index to Nursing and Allied Health Literature (CINAHL -Elton B. Stephens Company [EBSCO]), Cochrane Library (Wiley), Dissertation & Thesis Global (ProQuest), Embase (Elsevier), Medline (OVID), PubMed (National Library of Medicine), Scopus (Elsevier), and Web of Sciences (Clarivate) identified 1,451 articles published between January 2015 and June 2023.

Results

After independent review, 7 total studies were included. Six of the studies found an association between dietary acid load and progression of CKD.

Conclusions

Dietary counseling focusing on decreasing dietary acid load may be beneficial for individuals with CKD.

膳食酸负荷对慢性肾病患者肾小球滤过率的影响

导言：慢性肾脏病患者发生代谢性酸中毒的风险增加。研究表明，代谢性酸中毒会恶化肾功能，加剧全身炎症。高蛋白饮食会加重代谢性酸中毒，因为蛋白质食物偏酸性，而水果和蔬菜偏碱性。本系统综述的主要目的是确定患有慢性肾脏病 1-5 期的成人多吃水果和蔬菜是否会降低 eGFR 的下降率：在CINAHL (EBSCO)、Cochrane Library (Wiley)、Dissertation & Thesis Global (ProQuest)、Embase (Elsevier)、Medline (OVID)、PubMed (NLM)、Scopus (Elsevier)和Web of Sciences (Clarivate)中检索了2015年1月至2023年6月期间发表的1451篇文章：经过独立审查，共纳入 7 项研究。其中六项研究发现 DAL 与慢性肾脏病的进展存在关联：结论：以降低 DAL 为重点的饮食咨询可能对 CKD 患者有益。
