Introduction
The association between egg intake and risk of type 2 diabetes mellitus has been investigated in recent years in several prospective observational studies, which show contradictory results[1–4].Previous estimates from population-based surveys in Germany assume 7–8% of type 2 diabetics in the adult population [5–7] with a proportion of unrecognized (untreated) diabetes mellitus among the overall prevalence of over 20and up to 50% [5, 7–9]. Results vary however depending on the age group studied and the data pool used[10]. In one recent study a 9.5% prevalence of type 2 diabetes mellitus was calculated based on overall accounting data from German physicians who treat state-insured patients [11].
This article presents the results of systematic reviews and meta-analyses as well as more recent intervention and cohort studies examining the effects of egg intake on the risk of type 2 diabetes mellitus and cardiometabolic risk factors. Taking account of the previous article (part 1) which presented, inter alia, the status of current studies on the association between egg intake and cardiovascular diseases, the results are then discussed.
Abstract
Following on from the previous publication (part 1) summarizing study results on the association between egg intake and risk of cardiovascular diseases, the aim of this article was to assess the association between egg intake and risk of type 2 diabetes mellitus and the effect on cardiometabolic risk factors. Overall, study results from previous meta-analyses, systematic reviews and recently published cohort and intervention studies show no clear negative or positive effects of egg intake on the investigated outcomes. Therefore, the focus should be placed on overall nutrition quality rather than a discussion on limiting egg intake or associated dietary cholesterol.
