Welcome to Worth-a-Word Wednesdays, where I review and summarise a study or article 📖 that I think provides some useful and interesting information. This week – The association of saturated fat with cardiovascular disease! ❤️
Article Title: Meta-analysis of prospective cohort studies evaluating the association of saturated fat with cardiovascular disease
This study was published by Siri-Tarino, P. W., Sun, Q., Hu, F. B., & Krauss, R. M. (2010). In the American Journal of Clinical Nutrition, 91(3), 535-546.
This meta-analysis evaluated the evidence related to dietary saturated fat and its association with risk of coronary heart disease (CHD), stroke, and cardiovascular disease (CVD).
21 studies qualified for this analysis and the results are as follows;
•Markedly, studies that reported positive associations between saturated fat and CVD were specific to subgroups of the study population i.e- older vs younger participants, male vs female participants. 🧐
•10 of the studies evaluated did not report any statistically significant association between dietary saturated fat and CHD
•The authors stated that their results suggested publication bias 🚫, as that studies that showed an increased association between saturated fat and CVD were inclined to receive more favourable publication, 😮 “Our results suggested publication bias, such that studies with significant associations tended to be received more favourably for publication. If unpublished studies with null associations were included in the current analysis, the pooled relative risk estimate for CVD could be even closer to null.” 👍
•The analysis concluded that there is insufficient evidence from prospective studies to conclude that dietary saturated fat is associated with an increased risk of CHD, Stroke or CVD.👀
