Although St-Jules et al have presented the case for postprandial hyperkalemia with food, including plant foods, there (still) is little to no direct evidence supporting the occurrence of postprandial hyperkalemia, mostly due to a lack of studies performed exclusively using food. Food is different than salts or supplements, and it is likely that a banana behaves differently than potassium salts. A growing body of evidence supports the use of plant foods without causing hyperkalemia in patients with kidney disease. Currently, only 1 study has reported on the postprandial effects of hyperkalemia. In this study, there was a substantial reduction in the instances of postprandial hyperkalemia in participants consuming a diet that included more plant foods and more fiber. At the time of this writing, there is no evidence to support risk or safety of certain foods with regard to postprandial hyperkalemia, and additional research is warranted.
虽然 St-Jules 等人提出了食物（包括植物性食物）引起的餐后高钾血症的情况，但目前几乎没有直接证据支持餐后高钾血症的发生，这主要是因为缺乏专门使用食物进行的研究。食物与盐或补充剂不同，而且香蕉的行为可能与钾盐不同。越来越多的证据支持在不引起肾脏病患者高钾血症的情况下使用植物性食物。目前，只有 1 项研究报告了高钾血症的餐后影响。在这项研究中，参与者食用富含植物性食物和更多纤维的饮食后，餐后高钾血症的发生明显减少。在撰写本文时，没有证据表明某些食物与餐后高钾血症的风险或安全性有关，需要进一步研究。
