PURPOSE OF REVIEW
The Covid-19 pandemic has daunted the world with its enormous impact on healthcare, economic recession, and psychological distress. Nutrition is an integral part of every person life care, and should also be mandatorily integrated to patient care under the Covid-19 pandemic. It is crucial to understand how the Covid-19 does develop and which risk factors are associated with negative outcomes and death. Therefore, it is of utmost importance to have studies that respect the basic tenets of the scientific method in order to be trusted. The goal of this review is to discuss the deluge of scientific data and how it might influence clinical reasoning and practice.
RECENT FINDINGS
A large number of scientific manuscripts are daily published worldwide, and the Covid-19 makes no exception. Up to now, data on Covid-19 have come from countries initially affected by the disease and mostly pertain either epidemiological observations or opinion papers. Many of them do not fulfil the essential principles characterizing the adequate scientific method.
SUMMARY
It is crucial to be able to critical appraise the scientific literature, in order to provide adequate nutrition therapy to patients, and in particular, to Covid-19 infected individuals.
目的综述
新冠疫情对全球医疗保健、经济衰退和心理困扰造成了巨大影响，令世界陷入恐慌。营养是每个人生活护理的重要组成部分，在新冠疫情期间，也应强制性地纳入患者护理。了解新冠病毒如何发展以及哪些风险因素与不良结局和死亡相关至关重要。因此，重要的是要有尊重科学方法基本原理的研究，以获得信任。本综述的目的是讨论大量的科学数据，以及这些数据如何影响临床推理和实践。
最近的发现
全世界每天都有大量的科学论文发表，新冠疫情也不例外。到目前为止，有关新冠病毒的数据来自最初受疾病影响的国家，主要是流行病学观察或观点论文。其中许多不符合适当科学方法的基本原理。
总结
为了能够为患者提供适当的营养治疗，特别是为新冠病毒感染者提供适当的营养治疗，批判性地评估科学文献至关重要。
