Pooled hazard ratios for type 2 diabetes were 0.81 for whole grain cold breakfast cereal and 0.79 for dark bread when comparing those consuming one or more servings a day to those consuming less than one serving a month.
Incorporating whole grain cold breakfast cereal and dark bread into the diet may significantly lower diabetes risk.

For individual whole grain foods, pooled hazard ratios (95% confidence intervals) for type 2 diabetes in participants consuming one or more servings a day compared with those consuming less than one serving a month were 0.81 (0.77 to 0.86) for whole grain cold breakfast cereal, 0.79 (0.75 to 0.83) for dark bread.
Why this rating
