摘要

营养科学因其方法论而受到批评,其发现明显矛盾,并引发争议而非共识。然而,尽管对该领域的某些批评对于发展一门更有说服力的科学是有效和有信息的,但在这些论述中,对饮食和营养的研究也有一些独特的考虑,要么被忽视,要么被遗漏。在非传染性心脏代谢疾病的负担在人群中持续增加之际,正在进行的关于营养科学效用的批判性讨论正在进行。营养科学和其他学科领域的任务是建立一个转化证据库,以改善人口和个人健康,降低疾病风险。因此,探索营养研究的独特方法论和认识论考虑对于营养研究人员、学生和从业者来说是重要的,以进一步发展一门改进的营养科学学科。本文将扩展营养研究面临的一些挑战,讨论营养流行病学、随机对照试验和荟萃分析的方法学方面,以及如何将这些考虑因素应用于改进研究方法。还提出了一种实用的营养科学研究范式,将方法论置于其中心,允许我们如何获得知识和研究设计作为产生这些知识的方法这两个问题相互联系,为营养研究领域提供了一个框架,在这个框架内捕捉营养和饮食的全部复杂性。

Need for a nutrition-specific scientific paradigm for research quality improvement.

Nutrition science has been criticised for its methodology, apparently contradictory findings and generating controversy rather than consensus. However, while certain critiques of the field are valid and informative for developing a more cogent science, there are also unique considerations for the study of diet and nutrition that are either overlooked or omitted in these discourses. The ongoing critical discourse on the utility of nutrition sciences occurs at a time when the burden of non-communicable cardiometabolic disease continues to rise in the population. Nutrition science, along with other disciplinary fields, is tasked with producing a translational evidence-base fit for the purpose of improving population and individual health and reducing disease risk. Thus, an exploration of the unique methodological and epistemic considerations for nutrition research is important for nutrition researchers, students and practitioners, to further develop an improved scientific discipline for nutrition. This paper will expand on some of the challenges facing nutrition research, discussing methodological facets of nutritional epidemiology, randomised controlled trials and meta-analysis, and how these considerations may be applied to improve research methodology. A pragmatic research paradigm for nutrition science is also proposed, which places methodology at its centre, allowing for questions over both how we obtain knowledge and research design as the method to produce that knowledge to be connected, providing the field of nutrition research with a framework within which to capture the full complexity of nutrition and diet.
