Fish intake and type 2 diabetes in Japanese men and women: the Japan Public Health Center–based Prospective Study

Abstract

In a population with high fish and seafood intake, fish consumption was associated with a lower risk of type 2 diabetes in men but not in women.

Fish consumption is inversely associated with type 2 diabetes in Manitoba First Nations communities

“…Our findings are consistent with a number of previous population-based prospective cohort studies on the relationships between fish consumption and n-3 FAs intake on the one hand and T2D prevalence on the other, conducted among different populations (Patel et al 2009;Nanri et al 2011;Villegas et al 2011). Patel et al (2009 reported that consumption of one or more portion of fish per week decreased the OR for diabetes by about 25% compared with less than one portion per week in analyses adjusted for a number of risk factors for diabetes.…”

“…Patel et al (2009 reported that consumption of one or more portion of fish per week decreased the OR for diabetes by about 25% compared with less than one portion per week in analyses adjusted for a number of risk factors for diabetes. Nanri et al (2011) found that fish intake in men was significantly associated with a decreased risk of T2D with the OR values of T2D prevalence for the highest compared with the lowest quartile of intake being 0.73 (95% CI: 0.54-1.00) for total fish intake and 0.68 (95% CI: 0.5-0.92) for small and medium fish. Villegas et al (2011) found that the relative risks for quintiles of fish intake were 1.…”

“…Recent meta-analyses of prospective studies found that in the overall analysis, fish consumption and dietary n-3 FAs intake were not associated with lower risk of T2D (Wallin et al 2012;Wu et al 2012;Zheng et al 2012). However, geographical differences in the associations were demonstrated with a protective effect of fish and n-3 FAs consumption on T2D in Asian countries (Nanri et al 2011;Villegas et al 2011) and positive associations in the US population (Kaushik et al 2009). This heterogeneity may originate from several sources including genetic differences or genediet interactions (Dedoussis et al 2007;Lee et al 2011).…”

“…The results of epidemiological studies in general populations have been inconsistent regarding the association between fish consumption and n-3 FAs and T2D prevalence. Several prospective cohort studies reported protective effects of fish consumption and n-3 FAs intake on the risk of T2D (Patel et al 2009;Nanri et al 2011;Villegas et al 2011), whereas some studies suggest positive (Kaushik et al 2009;Djoussé et al 2011) or no associations (van Woudenbergh et al 2009). Meta-analyses reported geographical differences in the associations between fish consumption, n-3 FAs, and the development of T2D; a protective association was observed in the populations of Asian countries, and a positive association was observed in the American population (Muley et al 2014).…”

Dietary Protein Intake and Incidence of Type 2 Diabetes in Europe: The EPIC-InterAct Case-Cohort Study

“…In our analyses, protein from dairy and protein from cheese were not accountable for the reported reduced type 2 diabetes risk associated with dairy (14-16) and cheese consumption. Fish consumption is not associated with type 2 diabetes (20)(21)(22)(23)39), so possibly our observed association between animal protein and increased type 2 diabetes risk is counterbalanced by potential risk-reducing nutritional components of fish. The findings of this study did not confirm the suggested reduced type 2 diabetes risk associated with protein intake from plant products (especially legumes [18] and nuts [19]).…”
