Fatty acids (FAs) can be classified into saturated (SFA), unsaturated (poly-or monounsaturated) and trans FA. Recent studies have found that both the quantity and quality of dietary FAs may influence their role in metabolic pathways. Due to their chemical composition, some FAs play a major role in the development and progression of cardiovascular disease. This is especially true for SFA and n-3 polyunsaturated fatty acids, which include marine eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA). The proinflammatory effects of high SFA intake may increase the risk of atherosclerosis. On the other hand, dietary n-3 intake may reduce the risk of cardiovascular disease by decreasing atherosclerosis, inflammation, and thrombotic processes. The goal of this study was to review the current literature on the role of FA intake in the prevention and risk of cardiovascular disease.
Keywords: Fatty acids; cardiovascular disease
ARTICLE SUMMARYStrengths: The few studies linking diet and the consumption of fatty acids to cardiovascular disease increase the strength of this research. Limitations of this study: Literature review study with cross-sectional design.
Objectives: Body composition changes are associated with adverse effects such as increased insulin resistance (IR) in individuals with diabetes mellitus. This study aims to evaluate the association between different body adiposity markers and IR in adults with type 1 diabetes (T1D). Subjects and methods: The cross-sectional study included outpatient adults with T1D from a university public hospital in southern Brazil. The body adiposity markers studied were waist circumference (WC), waist-height ratio (WHtR), body mass index (BMI), conicity index (CI), lipid accumulation product (LAP) and body adiposity index (BAI). IR was calculated using an Estimated Glucose Disposal Rate (EGDR) equation (analyzed in tertiles), considering an inverse relation between EGDR and IR. Poisson regression models were used to estimate the odds ratio (OR) and 95% CIs of association of adiposity markers with IR. Results: A total of 128 patients were enrolled (51% women), with a median EGDR of 7.2 (4.4-8.7) mg.kg -1 .min -1 . EGDR was negatively correlated with WC (r = -0.36, p < 0.01), WHtR (r = -0.39, p < 0.01), CI (r = -0.44, p < 0.01), LAP (r = -0.41, p < 0.01) and BMI (r = -0.24, p < 0.01).
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
