We observed that intake of total fish was associated positively with risk of type 2 diabetes (1). Stratification by type of fish showed that intake of lean fish tended to be associated with risk of type 2 diabetes, whereas intake of fatty fish was not. In line with our results, Boucher and Mannan (2) observed that overall fish intake was associated positively with glycemia in British Bangladeshi adults. In contrast, intake of fatty fish rich in vitamin D was associated with lower levels of glycemia. However, the intake of fatty fish in our study population (18% of total fish intake), and consequently of vitamin D from fish (12% of total vitamin D intake), was lower than observed by Boucher and Mannan. Therefore, we cannot exclude that higher intake of fatty fish may be associated with lower risk of type 2 diabetes. In our study, intake of dairy was the main contributor to total intake of vitamin D (29%), followed by intake of meat (28%), and eggs (13%).
