Whole Grain Bread Yes, Red Meat No

At the German Institute of Human Nutrition Potsdam-Rehbruecke, researchers performed a cross-sectional study on 2,198 men and women in the larger EPIC study, searching for biological predictors of diabetes and cardiovascular disease. They found that higher consumption of whole grain bread was significantly associated with lower levels of several biomarkers of obesity, inflammation and glucose metabolism, while higher consumption of red meat was associated with higher levels of GGT (gamma-glutamyl transferase, which can be indicative of congestive heart failure) and hs-CRP (a measure of inflammation also associated with heart disease).
