Chronic kidney disease (CKD) is a major global health challenge, significantly contributing to morbidity and mortality due to its strong association with cardiovascular complications, metabolic imbalances, and reduced quality of life. Among the various interventions for CKD management, nutrition therapy plays a critical role in slowing disease progression and improving patient outcomes. The Plant-Dominant Low-Protein Diet (PLADO) has emerged as a promising dietary strategy that prioritizes plant-based protein sources while restricting overall protein intake, offering potential renal, cardiovascular, and metabolic benefits. This review evaluates current evidence on the efficacy of PLADO in CKD management, analyzing its impact on renal function, cardiovascular health, and systemic inflammation. Key findings suggest that PLADO can delay CKD progression, reduce dialysis dependence, and mitigate cardiovascular risks through lower dietary acid load, increased fiber intake, and anti-inflammatory properties. Additionally, PLADO has been shown to support gut microbiota diversity and reduce uremic toxin production, offering metabolic advantages beyond kidney health. While PLADO appears nutritionally adequate, concerns remain regarding protein sufficiency, potassium management, and long-term adherence. Its successful implementation requires tailored meal planning, patient education, and regular clinical monitoring to optimize outcomes and mitigate potential risks. This review highlights the importance of integrating PLADO into CKD management as a holistic, patient-centered dietary approach, particularly in regions like Cyprus, where no studies have evaluated its applicability. By synthesizing existing research, this review provides insights for clinicians, dietitians, and researchers to further explore long-term outcomes, adherence strategies, and feasibility across diverse healthcare settings. Future studies should focus on large-scale randomized controlled trials (RCTs) to establish PLADO's role in CKD dietary guidelines and clinical practice.
慢性肾脏病(CKD)是一项重大的全球健康挑战,因其与心血管并发症、代谢失衡以及生活质量下降密切相关,对发病率和死亡率有显著影响。在慢性肾脏病管理的各种干预措施中,营养治疗在减缓疾病进展和改善患者预后方面起着关键作用。以植物为主的低蛋白饮食(PLADO)已成为一种有前景的饮食策略,该策略优先选择植物性蛋白质来源,同时限制总体蛋白质摄入量,具有潜在的肾脏、心血管和代谢益处。本综述评估了目前关于PLADO在慢性肾脏病管理中疗效的证据,分析了其对肾功能、心血管健康和全身炎症的影响。主要研究结果表明,PLADO可以通过降低饮食酸负荷、增加纤维摄入量和抗炎特性来延缓慢性肾脏病进展、减少透析依赖并降低心血管风险。此外,PLADO已被证明有助于维持肠道微生物群多样性并减少尿毒症毒素产生,除了对肾脏健康有益外,还具有代谢优势。虽然PLADO在营养方面似乎足够,但在蛋白质充足性、钾管理和长期依从性方面仍存在担忧。其成功实施需要量身定制的饮食计划、患者教育以及定期临床监测,以优化治疗效果并降低潜在风险。本综述强调了将PLADO作为一种全面的、以患者为中心的饮食方法纳入慢性肾脏病管理的重要性,特别是在塞浦路斯等地区,尚无研究评估其适用性。通过综合现有研究,本综述为临床医生、营养师和研究人员提供了见解,以便进一步探索不同医疗环境下的长期治疗效果、依从策略和可行性。未来的研究应侧重于大规模随机对照试验(RCT),以确定PLADO在慢性肾脏病饮食指南和临床实践中的作用。
