55465名调查参与者的年龄在50-65岁,其中7417人在随访期间被诊断为2型糖尿病;
每天摄入16克全谷物食物,可将男性和女性的2型糖尿病患病风险分别降低11%和7%;
对于男性,纳入研究的所有谷物(小麦、黑麦、燕麦)的摄入量均与2型糖尿病风险降低显著相关;
而女性中只有小麦和燕麦摄入量与2型糖尿病风险降低显著相关;
在不同的全谷物产品中,黑麦面包、全麦面包和燕麦片/木斯里麦片显著降低了男性和女性患2型糖尿病的风险。

Abstract:
BACKGROUND: Type 2 diabetes is a major health concern worldwide. Whole grains and cereal fiber may offer protective effects on type 2 diabetes risk. However, few studies have been conducted in cohorts with detailed information on whole-grain cereal intakes and product types and with wide ranges of intake.
Objective: We investigated the associations between whole-grain intake, including intakes of different cereal types and products, and the risk of type 2 diabetes in a population with wide and diverse whole-grain intake.
Methods: We used data from the Danish Diet, Cancer, and Health cohort including 55,465 participants aged 50-65 y at baseline. Of these, 7417 participants were diagnosed with type 2 diabetes during follow-up (median: 15 y). Detailed information on the intake of whole-grain products was available from a food-frequency questionnaire, and total whole-grain intake and whole-grain cereal types (wheat, rye, oats) were calculated in grams per day. Associations were examined by using Cox proportional hazards models with adjustment for potential confounders.
Results: Whole-grain intake was associated with an 11% and 7% lower risk of type 2 diabetes per whole-grain serving (16 g) per day for men and women, respectively [HR (95% CI)-men: 0.89 (0.87, 0.91); women: 0.93 (0.91, 0.96)]. For men, the intake of all whole-grain cereal types investigated (wheat, rye, oats) was significantly associated with a lower risk of type 2 diabetes, but only wheat and oats intake was significantly associated for women. Among the different whole-grain products, rye bread, whole-grain bread, and oatmeal/muesli were significantly associated with a lower risk of type 2 diabetes for both men and women.
Conclusions: In this cohort study, we found consistent associations between high whole-grain intake and lower risk of type 2 diabetes. Overall, an association was found for all different cereals and whole-grain products tested.
