The DASH dietary pattern may lead to an improvement in insulin sensitivity independent of weight loss .
The DASH diet may play an important role in glycemic control in long- term interventions .
OBJECTIVE Type 2 diabetes is a major public health problem .
The Dietary Approaches to Stop Hypertension ( DASH ) eating pattern may contribute to managing risk factors of type 2 diabetes .
The objective of this study was to conduct a systematic review and meta- analysis on r and omized controlled trials ( RCTs ) that examine the effects of DASH diet consumption on the indices of glycemic control such as fasting blood glucose ( FBG ) , serum fasting insulin level , and Homeostatic Model Assessment insulin resistance ( HOMA-IR ) .
Whole-grain intake and the risk of type 2 diabetes: a prospective study in men.
BACKGROUND Certain dietary components may play a role in the prevention of type 2 diabetes . OBJECTIVE We examined prospect ively the associations between whole- and refined-grain intake and the risk of type 2 diabetes  in a large cohort of men . DESIGN Men from the Health Professionals Follow-up Study without a history of diabetes or cardiovascular disease in 1986 ( n = 42898 ) were followed for < /=12 y. Intakes of whole and refined grains , measured every 4 y by use of food-frequency question naires , were used to predict subsequent type 2 diabetes risk through multivariate analysis . RESULTS We ascertained 1197 cases of incident type 2 diabetes . After adjustment for age ; physical activity ; cigarette smoking ; alcohol consumption ; family history of diabetes ; and fruit , vegetable , and energy intakes , the relative risk of type 2 diabetes was 0.58 ( 95 % CI : 0.47 , 0.70 ; P for trend < 0.0001 ) comparing the highest with the lowest quintile of whole-grain intake . The association was moderately attenuated when additionally adjusted for body mass index ( relative risk : 0.70 ; 95 % CI : 0.57 , 0.85 ; P for trend = 0.0006 ) . Intake of refined grains was not significantly associated with risk of type 2 diabetes . After further adjustment for magnesium intake , cereal fiber intake , and glycemic load , the association between whole grains and type 2 diabetes was attenuated and the trend no longer significant . CONCLUSIONS In men , a diet high in whole grains is associated with a reduced risk of type 2 diabetes in men that may be mediated by cereal fiber . Efforts should be made to replace refined-grain with whole-grain foods
